摘要
分析了南方电网2种典型系统运行方式下,安顺开关站至天生桥二级电站的500 kV线路始端三永故障发生后系统的稳定性问题,揭示了不同方式下该故障发生后导致系统失稳模式变化的原因,用扩展等面积准则(EEAC)理论解释了系统在较低负荷水平下反而失稳的机理,并定量分析了系统运行方式对南方电网稳定性的影响。
Concerned with a three phase to ground permanent fault occurred at the Anshun Switch Yard side on the 500 kV An-Tian transmission line in the South China power grid, the instability mechanism of the South China power grid when such a fault occurred is analyzed with the EEAC theory. The qualitative and quantitative explanations are also given to the cause of the stability difference when the South China power grid is operated at two different dispatching modes.
