摘要
研究了小水电并网运行后给大电网安全稳定运行带来的影响,通过建立小水电模型和电压稳定数学模型对并网后的电压稳定性进行了计算分析,并分析了电力系统负荷连续增长情况下对电力系统电压稳定的影响,找出影响电力系统电压稳定的主要原因.
The effects of small hydropower grid-connection on the safe and stable operation of large power grids were investigated. ＂Fhrough the establishment of the small hydropower model and the mathematical voltage stability model, the voltage stability of the grid-connected system was calculated, and the impact of continuous load growth on voltage stability of the power system was analyzed. Finally, the main factors that affected voltage stability were identified.
