Abstract：The co-phase power supply system was based on single power transformer with YN,d11-27.5 winding connection and four-leg active filters, which could save transformer and cancel section insulators. By controlling the active filter, not only the elimination of phase unbalance, harmonic filtering and reactive power compensation can be implemented, but also the capacity of transformer can be full used. Focused on the system, it was analyzed for its compensation current real-time detecting technology, and compensation device control technology. Simulation mode of the YN,d11-27.5 co-phase AT power supply system was built by Matlab/Simulink.
