Machines

This section describes the general properties of all machine components in Typhoon HIL's Schematic Editor, such as a three-phase induction machine, a permanent magnet synchronous machine with a cylindrical rotor, a DC machine, etc. There are currently 13 different machine components in Schematic Editor.

There are two basic approaches used in machine modeling: with current sources and voltage behind reactance (VBR). The first one is used for all the machines, while VBR models for induction and doubly-fed induction machines can be given on request.

All machines modeled as current sources have a Snubber tab in properties window where the value of snubber resistance can be set. This value can be set to an infinitive (inf) but it is not recommended when a machine is directly connected to the inverter, because a current source is directly connected to an open switch, as shown in Figure 1. Circuit representations of this circuit without and with resistors are shown in Figure 2 and Figure 3 respectively.

Figure 1: Machine connected directly to inverter

Figure 2: Circuit representation of machine and inverter when all the switches are open without resistors (not recommended)

Figure 3: Circuit representation of machine and inverter when all the switches are open with resistors (recommended)
