| 摘 要： | 近年来华东电网缺电严重,电网比较薄弱,在某一故障情况下存在电压稳定性问题。为了解决华东电网的电压稳定性问题,有必要合理配置各区域无功补偿。介绍了通过特征值法研究华东电网的稳定性问题,并找出弱母线,给出合理的无功补偿方案。通过对2004年夏季华东电网数据的计算给出了弱母线位置以及相应的无功补偿容量。

| Abstract: | Because of the severe power shortage in East China Power Grid in recent years, the Grid becomes relatively weak, and has some problems in voltage stability when faults occur. To solve the voltage stability problems in the Grid, the reactive compensation should be reasonably configured in every area. Studying the voltage stability in East China Power Grid with the method of characteristic value, the problem buses can be found out, and the rational reactive compensation plan is given. Through calculations on the data of the Grid in the summer of 2004, the problem buses are located, and the relevant reactive compensation capacity is confirmed. |
