Research on Emergency DC Power Support in Central China Power Grid
摘要
Abstract
The impact of HVDC power transmission modulation on security and stability of Central China power grid interconnected with North China power grid after the building up of 1000kV AC demonstration project is researched. The mechanism and implementation of emergency DC power support are analyzed and the simulation analysis on the ability of both interconnected power grid and UHVAC transmission line to bear the failure impact and the security and stability level of the whole system under the bipolar blocking occurred in HVDC system within Central China power grid is performed. Simulation results of emergency DC power support among four circuits of HVDC transmission lines within Central China power grid under bipolar blocking occurred in one circuit of HVDC transmission line show that it is efficient for keeping stability and reliability of power supply of interconnected power grid to adopt emergency DC power support within HVDC power transmission system..关键词
