Description

Variable Load network is based on the following circuit for threthree-phase load.

Mask Parameters

Resistor: This parameter sets the resistive value of RLC block.

Inductor: This parameter sets the inductive value of RLC block.

Capacitor: This parameter sets the capacitor value of RLC block.

Capacitor Resistor: This parameter sets the Capacitor resistive value of RLC block.

Sampling time: This parameter is used for offline simulation.

All the configurations mentioned above are only used for offline simulation.

Voltage Input Configuration

In order to map the voltage from variable load block back to eHS solver, variable load should be added as one custom input. And based on the following equations, each block has two outputs, where the first one represents voltage and the second one stands for current calculated in real-time simulation.

See the table below to know detailed info.

As an example, variable load input #1, #3 and #5 are mapped back to eHS solver since three are variable load blocks are used in eHS circuit.

Current Measurement Configuration

Under Variable Load Configurator mask, current measurement should target the one used in the eHS circuit. Based on the netlist info, Y01, Y02 and Y03 should be selected for current measurements of variable load blocks.
