| Abstract: | This paper lists out the transmission system equivalent circuit diagram,and builds the state matrix equations containing switch variables,according to the AC UHV experimental example projects of Jindongnan-Nanyang-Jingmen.It adopts Matlab 7.6/Simulink to build the UHV transmission system.Simulation and experiment results shows that AC UHV parallel reactor reactive power compensation can guarantee the stabilization of voltage under no load or light load condition;moreover it can restrain the power frequency overvoltage in sending and receiving ends by plunging into parallel reactors,under heavy load rejection condition.This design can improve the transient voltage stabilization of system. |
