This demo illustrates use of both SimPowerSystems and Simscape to model a On-Load Tap Changing (OLTC) 120/25 kV transformer regulating voltage on a three-phase 25-kV distribution network.

The demo is similar to the power_OLTCregtransformer demo of SimPowerSystems. However, instead of using Multi-Winding Transformer and Breaker blocks to perform tap selection, the OLTC regulating transformer provided in this model exploits Simscape flexibility to model a variable ratio transformer, thus avoiding use of switches. With this new model you can easily change the number of taps.

The model is connected to the SimPowerSystems network through Simscape Interface Elements blocks of powerlib library.
