Grid simulator
Description of the Grid Simulator component in Schematic Editor
The Grid Simulator is a component which consists of three single phase voltage sources, series resistances and inductances. It is used to simulate a three phase symmetric or asymmetric grid.
The internal structure of the Grid Simulator is shown in Figure 1. Phase voltage, line voltage and phase current measurements are included, as shown in Figure 1. In Table 1 the schematic symbol and properties window of grid simulator are shown.
