摘要
针对广西电网水电满发的迎峰度夏方式,以及枯大方式进行了广西电网动态稳定分析,并对多种检修方式进行了校核计算。全面分析正常方式和检修方式下广西电网存在的动态稳定问题。在广西电网完成PSS试验的机组PSS均投入运行的情况下,广西电网的动态稳定性良好。与广西电网范围内机组强相关的弱阻尼低频机电振荡模式的振荡频率一般都在1Hz以上,高于南方电网常见的区间振荡频率。
Dynamic stability of Guangxi power grid under high and low water level peek load operation modes is analyzed, and some repair modes are also verified by calculations. Results shows that Guangxi power grid has good dynamic stability when all PSS of generators which＇s PSS have been tested are put into use, and the oscillation frequencies of low damping oscillation mode that have strong correlations with generators in Guangxi power grid are above 1Hz, which is higher than the usual oscillation frequency area in CSG.
