The application of Distributed Power Flow Controller in Gan Quan–Xiang​ Fu 220 kV AC lines in Hu Zhou

Abstract

With the increase of the load, the proportion of receiving power and the proportion of new energy generation, the imbalance of power flow which is the mismatch between the line power flow and the current-carrying capacity becomes more and more serious in the process of power grid operation, resulting in the low operating efficiency of power grid assets. The Distributed Power Flow Controller (DPFC) is adopted to control the power flow, which has advantages of small size, light weight and low cost, etc. This paper introduces the working principle and development trend of DPFC and the configuration of DPFC in Gan Quan–Xiang Fu 220 kV line in Huzhou. Finally the simulation results is given to prove that DPFC can cooperate with AC line to operate stably.
