DC Constant Power Load

Description of the DC constant power load/source component in Schematic Editor

The DC Constant Power Load component, shown in Table 1, is a Schematic Editor library block from the Sources section. This component is capable of acting as either a DC load or source with current saturation capability. This component can be controlled from either HIL SCADA or from signal processing logic.

Table 1. DC Constant Power Load
component	component dialog window	component parameters
Single Phase Constant Power Load		Current limit Control method CPU core Execution rate Snubber resistance Signal access

Tab: General

The Current limit defines the value at which the output current will saturate.

There are two control methods avaliable: SCADA input and Signal input.

When the SCADA input method is selected, the power setpoint is provided via a built-in SCADA input (Pref). If this control method is selected, it is possible to specify on which CPU the signal processing in the component will be executed. If either option 1 or 2 is selected, signal processing will be executed on the selected core of the User CPU. If System is selected, signal processing code in the component will be mapped to the System CPU.
When the Signal inputs option is selected, power setpoints are provided through signal input port.

Execution rate is the signal processing time step for calculating output current value.

Figure 1. General tab in the DC Constant power load Properties window

Tab: Snubber

Since DC Constant power loads/sources are modeled as current sources, it is a good practice to add large resistances in parallel in order to avoid topological conflicts in the circuit. An example where this snubber resistance is required is when the contactor is directly connected to the power source. Without snubber resistances, the contactor switches cannot be opened as there must be a path for the current from the current source(s).
