英文摘要：

In the process of power grid construction, the problem of the transmission capacity bottleneck of voltage grade power flow is becoming more and more prominent, and the special high-voltage transmission capacity can＇t be fully utilized. Effective method is to improve the transmission capacity of the power flow section of the power flow section. Put forward a comprehensive evaluation method of multi voltage level of transmission channel flow, analysis and evaluation of different locations for the installation of phase shifter scheme optimization and uses the phase shifter to improve the optimal solution of the multi voltage grade power flow section. Simulation analysis of actual power grid. The simulation results can greatly improve the transmission capability of the power flow and can guide the installation position of the actual phase shifter, and have some guidance to the actual power network reconstruction and operation.
