500kv Transformers Network Monitor

500kv Transformers Network Monitor

Description. One phase of a three-phase transformer is connected on a 500 kV, 5000 MVA network. The transformer is rated 500 kV/230 kV, 450 MVA (150 MVA per phase). The flux-current saturation characteristic of the transformer is modeled with the hysteresis or with a simple piecewise nonlinear characteristic. A Three-Phase Programmable Voltage Source is used to vary the internal voltage of
