Research on AC/DC Hybrid Iteration Flow Calculation Algorithm for Metro Power Supply System

Metro power supply system is a typical hybrid AC/DC power supply system. Compared with the AC power flow algorithm, the AC/DC power flow algorithm still isn't mature, especially in metro power supply system. The author referenced present AC/DC power flow algorithm and proposed a solution scheme for practical engineering. This algorithm can reduce power flow calculation time through adjusting the power flow calculation of DC iteration. The simulation results show that the algorithm can accurately calculate the metro power flow and simulate different operations. The result is closed to actual working conditions. Therefore, this hybrid iteration algorithm provides effective approach to calculate AC/DC power flow and is suitable for metro traction power supply system.
