Answered: Data from Modbus communications for Battery ESS (Generic) component

Mon, 19 Oct 2026 14:00:24 +0000

There is an example that utilizes Modbus server component inside of BESS (Generic) component. You can find it in example explorer under communication protocols>modbus>client and server components 2 hils.

Of course, you don't need two HIL devices for this, you can just leave part with Modbus server component (second HIL is used just for Modbus Client).

Hope this helps!

HIL604 loses PTP "Synchronized" ~15 s after start; simulation drifts -10 ppm vs grandmaster

Mon, 19 Oct 2026 13:21:28 +0000

Hello,

We use a HIL604 to drive IEC 61850-9-2 merging units that are themselves PTP-synchronized, so we need the HIL simulation to stay locked to the same PTP grandmaster. The HIL starts on a PTP second as expected, but it does not stay synchronized.

Setup

Device: HIL604, serial 00604-14-00536, firmware release 132776977 (as reported by the device manager), calibration date 2024-02-05.
Software: Typhoon HIL Control Center 2026.2, Python API typhoon_hil_api 1.31.3, controlled from a Linux PC (Debian 12) through the Python API.

Model: core/Time Synchronization component

sync_source PTP, eth_port 2, execution_rate 1e-4, no VLAN
ptp_config_select IEC61850-9-3: time_stamping hardware, network_transport L2, clientOnly 1, domainNumber 0, delay_mechanism P2P, logAnnounceInterval 0, logSyncInterval 0, logMinPdelayReqInterval 0, announceReceiptTimeout 3
The model is loaded, then the simulation is started again once PTP is present, so that it starts on a PTP second.
Network: HIL Ethernet port 2 connects to an industrial switch on our process bus. The grandmaster is a Meinberg on the same switch. Other PTP clients on the same switch with the same profile (linuxptp ptp4l, P2P, hardware timestamps) hold lock at about 200 ns rms, with a valid peer delay of about 570 ns.

What we observe

After a start, the Time Synchronization outputs read PTP = 1 and Synchronized = 1.
15.7 s after the start, Synchronized drops to 0 and stays 0 for the rest of the run. PTP stays 1 the whole time (polled once per second).
The simulation does not track the grandmaster's time. We measure the phase of a 50 Hz sine source from the HIL at a PTP-synchronized merging unit, which time-stamps its samples against the same grandmaster. Over 12 s windows the phase drifts by −6 to −11 ppm. A separate 90 s run gave a steady −9.4 ppm, i.e. the simulation time runs about 9.4 µs per second slow. The drift starts right after the start, while Synchronized is still 1.
−10 ppm over 15.7 s is about 150 µs, which may be the limit at which Synchronized is cleared.
Restarting the simulation (stop and start, no reload) repeats the pattern every time.

Questions

Does the HIL604 steer its simulation time base to PTP continuously during a run (full device synchronization over Ethernet port 2), or does it only align the start?
What condition clears the Synchronized output while PTP stays 1, and what is the threshold?
Is there a way to read the PTP servo state, offset and path delay of the HIL during a run (status component, log, or API call)?
Is this a known issue with HIL604 firmware or THCC 2026.2, and is it fixed in 2026.3 or later?
Would IRIG-B on the HIL604 keep the simulation locked during the run, if PTP cannot?

We can provide the model file, packet captures of the PTP traffic on the HIL port, and the phase measurements if useful.

Answered: Inter turn Short Circuit in 3 Phase Induction motor model

Mon, 19 Oct 2026 06:52:58 +0000

Greetings Daniel,

Typhoon’s ITSC model is based on Alberto Berzoy, Ahmed A. S. Mohamed, Osama Mohammed, Complex-Vector Model of Interturn Failure in Induction Machines for Fault Detection and Identification, IEEE, 2016 (link).

Severity factor µ: the fraction of a phase’s total series turns that are shorted, µ = N_shorted / N_total. It’s a pure turns ratio, not a percentage of resistance or current.

Rf: the resistance of the short-circuit path itself, separate from µ. It represents the fault’s own impedance.

Regarding your idea, we’ll keep it in consideration, but especially for real-time simulation, this level of detail would dramatically increase the computational power the model requires.

Best regards,

Parallel Connection of Two Photovoltaic System Inverters

Thu, 08 Oct 2026 05:36:09 +0000

Dear Sir/Madam,

Greetings.

I have been experimenting with the parallel connection of two photovoltaic (PV) power converters and have encountered problems that I am unable to resolve.

Specifically, I am analyzing two PV converters that are connected in parallel on the AC side, while their DC-side PV arrays can be considered to be connected in series. When I use isolation transformers between the grid and the AC side of both converters (Case 0), the system operates entirely according to my expectations and remains stable. Even when I remove one isolation transformer from Case 0 while keeping the other, the entire system still operates properly and stably. However, if I remove both isolation transformers from the model (Case 1), a system-wide malfunction occurs. This is manifested by oscillations in the DC quantities (current, voltage, and power), and PV converter No. 2 (PV_C_2) is unable to deliver power.

You can find both models (Case 0 and Case 1) at the following link: https://drive.google.com/file/d/1lpCIXH-3DtK7pMdBEZ4tkI5E0KwZtS7R/view?usp=sharing

I have searched for reasons in the literature and via AI, where I found that the issue might be caused by circulating currents between the two parallel-connected inverters, due to their PWM generators not being synchronized. Please let me know if you can help me improve the model to achieve synchronization between the two inverters, so I can attempt to resolve this drawback that way. I tried adding an external PWM signal to each inverter, but I was unsuccessful and do not see a way to synchronize the signals.

What is your opinion? Would this approach solve the problem? Is there an example of external control available somewhere?

I look forward to hearing from you as soon as possible.

Using THCC on a HPC cluster

Tue, 06 Oct 2026 07:27:57 +0000

Hello,

I have extended one of the Typhoon HIL IBR examples to include two IBRs. The resulting model requires significantly more RAM to compile than my workstation has available.

My university can provide access to HPC nodes with much larger memory capacity, so I'd like to install and run Typhoon HIL Control Center there.

I already have a valid Typhoon HIL licence, but I am unsure whether the current licence terms/documentation permit installation and use on a university HPC compute node.

Has anyone used Typhoon HIL Control Center on an HPC cluster or similar computing environment before?

Also, can anyone point me to a phrase in the current Typhoon HIL documentation or licence terms confirming that there is no restriction on using a valid user licence on a university HPC compute node?

I have already contacted Typhoon HIL support and am awaiting their response, but I would appreciate hearing from anyone who has done something similar in practice.

Kind regards,

Answered: HIL Scada vs TyphoonSim

Fri, 25 Sep 2026 19:32:42 +0000

It could be that your model contains some dynamics that are faster than the simulation step chosen for VHIL can track. TyphoonSim is an offline simulation tool, and it can adjust the step to capture all dynamics. On the other hand, VHIL (as an emulator of a HIL device) uses a fixed simulation step, and if you didn't set it properly, then you might experience different results. Anyway, you need to be a bit more specific in describing the difference, so that the cause can be identified.

ISO 15118-2 EVCC/SECC stuck at PowerDeliveryStart — EVSEPresentVoltage/Current stay at 0, never reaches CurrentDemand

Fri, 21 Aug 2026 12:10:04 +0000

Setup:

I'm new to Typhoon HIL and still learning the software. I'm simulating both the EV side and EVSE side on the same model (not on separate HIL targets) — using the ISO 15118-2 EVCC block and the ISO 15118-2 SECC block, connected through a contactor-based charging circuit model, all within one simulation. I'm testing a DC fast charging sequence.

Symptom:

The session progresses successfully up to PowerDeliveryStart, but does not move forward into CurrentDemand. EVSEPresentVoltage and EVSEPresentCurrent stay at 0 throughout, and the state machine just holds at this point rather than throwing any explicit error or fault code.

Question:

Since I'm still new to this environment, I'd appreciate guidance both on the expected signal chain and on whether simulating both EVCC and SECC together in a single model/HIL setup (rather than on separate targets) could itself be a factor here. Is there a known interlock (contactor feedback, target current/voltage validity, or IsEVReady) that must be satisfied before the EVCC block will issue the first CurrentDemandReq? What is the expected signal chain from PowerDeliveryRes to the first CurrentDemandReq inside this library block, so I can figure out where the chain is breaking?

Need the schematic for HIL DSP 180 Interface Board

Fri, 21 Aug 2026 12:09:59 +0000

Dear Typhoon HIL Team,

I am using the TMDSCNCD28P55X ControlCARD from Texas Instruments (TI) with the DSP180 Interface 1.3 board from Typhoon HIL.

The detailed documentation for the DSP180 Interface is available at:
https://www.typhoon-hil.com/documentation/typhoon-hil-hardware-manual/hil_dsp_180_interface/References/detailed_description.html

However, the pin mapping information provided in the documentation does not appear to fully match the TMDSCNCD28P55X ControlCARD, particularly for the analog output (AO) connections. It is therefore difficult for us to identify the correct connection and MCU/DSP pin mapping through the HSEC 180-pin connector.

Could you please provide the complete pin mapping between the DSP180 Interface 1.3 and the TMDSCNCD28P55X ControlCARD, including:

Analog Output (AO) channels and their corresponding DSP/MCU pins
Digital Input (DI) and Digital Output (DO) channels and their corresponding GPIOs
HSEC 180-pin connector pin numbers
Any relevant signal conditioning or scaling information

A complete pin-to-pin mapping table would be very helpful for us in configuring and using the TMDSCNCD28P55X ControlCARD with the DSP180 Interface.

Thank you for your support.

Answered: On choosing appropriate settings and execution rate for 100 kHz AO signals

Fri, 14 Aug 2026 07:38:40 +0000

Hi Uddhav,

Just so you know, you can continue commenting on the original post. That's the most efficient way to resolve things.

My response remains the same: The update rate of the analog outputs is equal to your time step. That means that the value of voltage on the analog output is updated once every several 100s of nanoseconds. Thus, it is expected that the waveform will appear as non-smooth at the analog output. That will be more visible the more you zoom in on the time axis.

Answered: Distorted waveforms at AOs of HIL 101 outputs in DAB ultracore example

Thu, 13 Aug 2026 14:01:28 +0000

Hi Uddhav,

The update rate of the analog output update rate is equal to the simulation time step (the "large one", used by the SPC, which is probably around 300-500ns). It is not as fast as the UltraCore step of 4.5ns on HIL101. This is a fundamental limitation in the hardware. In your case it looks as if the analog outputs are updated every 500ns. If you reduce your time step, you will have a better update rate, but best case scenario is 200--250ns, which will not yield fully smooth waveforms at 100kHz.

Is your controller directly sensing the transformer current in order to derive the control?

Wed, 08 Jul 2026 13:20:58 +0000

Regarding your question about the internal modulator, if you set the duty cycle to D through the "in" port, the modulator will generate two gate pulses with a duty cycle of D, phase-shifted by 180°. For a switching frequency of 10 kHz and a duty cycle of 0.25, the resulting gate signals are shown in the figure below.

The transformer parameters N1 and N2 represent the total number of turns in the primary and secondary windings, respectively.

Variable Load (Generic) does not draw power even with Pref set in per-unit and contactor closed — output stays near 0

Mon, 15 Jun 2026 07:01:02 +0000

Hi, I'm a bit stuck and hoping someone can point me in the right direction.

I have a simple microgrid running on a HIL 402: a Grid, a PV Power Plant (Generic), a Battery ESS (Generic) and one Variable Load (Generic), all on a common bus. I'm setting the load's Pref from a SCADA slider and measuring its power.

The issue is that the load just won't draw power. When I set Pref to 1.0 p.u. (which I'd expect to be full nominal), the load only shows about 0.01 kW, even though its nominal active power is 10 kW. The per-unit reference seems fine now since it's not saturating anymore, but nothing actually flows into the load. Meanwhile Grid and PV both read around 14 kW, so the sources are clearly working — the power just isn't reaching the load.

I've already sent Pref in per-unit, closed all the contactors in the panel init (including the load's, 'Variable Load (Generic)1.Grid Converter1.Contactor.S1'), and set the load Enable to 1.

So I'm wondering what I'm missing. Is there something else the Variable Load needs to actually start drawing power — some converter enable, a Qref, a connect signal, or a particular order I should follow? And is there a way to confirm the contactor is really closed during the simulation?

Thanks a lot for any help.

2. Most components that require a Grid Resources license, such as DER components (i.e. switching, average, and generic components that were part of the Microgrid toolbox) and Controller components (ie. components that were part of the Power Systems toolbox) can now be found in the Grid Resources category.

3. Load components have been moved to a new Sinks library category.

Sine Wave in VHIL but Mountain-shaped in C-HIL (TI C2000)

Mon, 04 May 2026 07:12:53 +0000

I am experiencing a strange discrepancy between my VHIL/HIL-to-HIL tests and my actual C-HIL setup.

My system overview:
- GFL inverter with LCL Filter (DC Link: 800V | Grid: 311 Vpeak).
- The plant (inverter and grid) built in Typhoon HIL simulator (HIL604)
- The controller programmed in TI C2000 MCU (Ti28069m) via PLECS Coder.
- PLECS Coder (MCU side) discretization is set to 1e-4. Typhoon HIL is set to "Auto" discretization.

I have successfully built and tested the complete control structure all the way to the outer loop (using power reference to generate the current reference). In this HIL-to-HIL environment, everything works great. Even when applying very high power references that cause some natural distortion, the grid current strictly maintains its sinusoidal shape.

When transitioning to the physical C-HIL, I rebuilt the system step-by-step.

The open-loop tests are perfectly fine (the TI MCU reads the ADC signals safely, and the PWM signals sent back to Typhoon HIL are correctly received).

However, the moment I close just the inner loop (current control), the system breaks. The grid current loses its sine shape entirely and becomes a mountain-shaped waveform.

Looking at the data, the output from the dq-to-abc transformation block shoots up to ~800V. Since the grid is 311V peak, the controller should ideally only demand around ~380V. This massive 800V request heavily saturates the PI controller and completely overmodulates the inverter. (I actually already tried manually scaling down this massive control output so it would safely fit into the PWM limits without overmodulating, but the resulting current still remained in that distorted, mountain-like shape.)

Are there specific execution/task synchronization settings between PLECS Coder and Typhoon HIL that I might have missed when transitioning from HIL-to-HIL to C-HIL? or any ideas on what this issue could be would be greatly appreciated!

Hello Daniel,

Without the model itself, or at least the error log you are receiving, it would be very difficult for us to determine the reason for the compilation failure.

Based on my experience, I can say that the dimensions of input signals for this component can sometimes be counterintuitive. For example, I would advise you to double-check whether the signals connected to the 'Pref' and 'Qref' terminals have a dimension of 3 as indicated in the documentation (LINK).

Answered: PFC boost converter in Typhoon HIL

Wed, 08 Apr 2026 06:48:26 +0000

Hi Mamadou,

I don't see any screenshots in your post.

Theoretically, there are two distinct segments of your model: Circuit and closed loop control. My advice would always be to try to run in open loop to make sure your circuit operates as expected - before closing the control loops. In case of boost PFC, you can do that by just feedforwarding the grid voltage to boost modulator.

One thing that you might want to make sure is to follow the guide from documentation on this link: https://www.typhoon-hil.com/documentation/typhoon-hil-software-manual/References/single-phase_diode_rectifier.html#:~:text=The%20default%20state,of%20the%20simulation.

You can also consider using TyphoonSim to develop the controls, as that simplifies the circuit modeling.

Hi,

Physical connection between HIL and Launchpad can be done using HIL TI Launchpad interface.

Connection between PC and HIL device is done the same way regardless of which controller and interface you're using. You can access the HIL remotely if it's connected to the network via Ethernet.

I'd say that the main bottleneck you're facing is connection between the Launcphad and the PC. Having that in mind, the best setup would be a PC connected to the HIL and the Launchpad, which you can access remotely using Remote Desktop connection.

Hi Genis Joan Romano,

Let me try to help you here.
The license key which you received for HIL404 as per the second attached screenshot is invalid for real-time execution as it is just a virtual key(not meant for real-time, can only run simulation in software virtually).

However, the device license key for HIL402 which you have available is something different. You must contact the concerned person who has purchased the HIL402 device and they will share the hardware device key with you. Once you receive the key for HIL402 device, open Typhoon HIL software, go to the license option and at the bottom of the pop-up screen you can see change license option(attached picture 1- red block). Once you click there, you can insert the new alpha-numeric license key and restart the software.

After restart, you will be able to see HIL402 in the license window and then your hardware connection will be formed from device manager.

Regarding firmware, once the device is connected, just click on the sync firmware option on the device manager window and your firmware will be automatically synchronized with your current software version(attached picture 2- red block).

Hope this helps.

Try to install one by one following order mentioned above and try to log in (restart software first) when you finish installation. If it asks for password to unpack certificate, type 1234.

Answered: Inquiry on UDP Communication Usage and MAC-Related Changes in Typhoon HIL 2025.4

Thu, 15 Jan 2026 16:42:36 +0000

Hello,

You are correct — in newer versions, the UDP communication module includes an option to configure the MAC address, more precisely the last digit of the MAC address.
This option was not available in previous versions.

There was a bug in earlier versions related to MAC address handling, which we fixed by introducing this new feature. This change may have affected backward compatibility; however, since the functionality worked correctly before, there is no reason it should not work again once everything is properly configured.

Based on the fact that everything was working correctly before, it is clear that you have a good understanding of how UDP communication works. Therefore, there is nothing specific we need to advise you on in this regard.

It is only necessary to configure the last digit of the MAC address again.

Please override the last digit of the MAC address as follows:

Enable “Override last digit in MAC address”

If you were using eth port 2, enter 5 in the “Source device MAC address” field

If you were using eth port 3, enter 6 in the “Source device MAC address” field

If you were using eth port 4, enter 7 in the “Source device MAC address” field

If you continue to experience issues with UDP communication, I recommend using Wireshark as a debugging tool to verify the communication and confirm that the MAC address is set correctly.

Hello Alejandro,

To answer the first question, currently there is no way to actively monitor the amount of sent messages other than monitoring elapsed time and dividing it by the sample time at which messages are sent from the send block. The UDP send and TCP send blocks also have a status function which returns how many messages weren't sent in case that is useful in your case. Perhaps you could also count received messages on the server which receives them.

As for defining IPs in the model initialization script there seems to be a bug currently so this cannot be done. One workaround is to have the send blocks be in a subsystem that way you can use the pre_compilation code in the mask editor to define IP addresses. I will attach an Example model so you can get a better idea of how this can be done.

Answered: Issues Using Three-Phase Core Coupling in Parallel Inverter Simulation

Mon, 22 Dec 2025 15:21:54 +0000

Hello,

I recommend you 2 ways:
Reviewing the Recommended coupling page in Typhoon Documentationas in the previous answer given. Especially with series or parallel connected inverters.

Second, try to add the snubbers, maybe you only finally need a resistor and not the full one, because without snubbers you can have great distortions than change the results from what was expected.

Hope, this could work.
Kind regards.

Execution rate of the Triangular Wave Source component will decide the resolution of the component output. You might want to make sure that your execution rate is at least 100 times shorter than your switching period.

Even better, consider using the PWM Modulator component, to make sure you have the maximum resolution.

Answered: Exporting data real time in VHIL mode or TyphoonSim

Hello Haydar,

For Virtual simulation, the possibility is to export data using data logging widgets only. You can use signal data logger for .MAT or .CSV data storing OR you can use stream data logger for .CSV, .H5 or .MF4. In case for higher data rates, it is not recommended to use .CSV format.
You can use TCP/UDP protocol incase of physical device connection over Ethernet only.
