Method to Eliminate Flux Linkage DC Component in Load Transformer for Static Transfer Switch
Figure 16
Waves of the transfer strategy with flux linkage DC component elimination. (a) Three-phase sag fault. (b) A phase line-open fault. From the top to bottom, they are AB, BC, and CA phase transformer voltage, A, B, and C phase load current, and AB, BC, and CA phase transformer flux linkage.
