Abstract

Reactive power compensation scheme directly affects the overvoltage and safety operation of UHV AC transmission line. To maintain the voltage along the line in a reasonable range, reactive power compensation should change with the power flow dynamically. In the paper, a novel reactive power compensation scheme of UHV AC transmission line is proposed, which is based on the independent local power network. Compared to other plans, this method requires less reactive power compensation capacity of sending and receiving ends, and the transmission capability of UHV AC line can be increased through dynamic reactive power compensation adjustment with the change of power flow. Finally, the feasibility of this scheme is discussed through an demonstration UHV transmission line in China.
