小水电电压稳定问题研究

Research on the Small Hydropower Voltage Stability

本文研究了小水电电源供电电压不稳问题。本文采用在水电站至主网的干线中段位置加装有载调压装置的方法调整小水电电源在丰水期和枯水期的供电电压,算例表明加装有载调压装置后,可明显降低丰水期小水电供电电压,控制线路电压在正常水平,提高了对用户的供电质量。

This paper studied the voltage instability problem of small hydroelectric power. In this paper the voltage regulator with load was installed in the middle of the trunk line between hydropower station and main grid to adjust the hydroelectric power supply voltage during the wet season and dry season, numerical example showed that after adding voltage regulator with load, the hydropower power supply voltage decreased obviously, circuit voltage was controlled in the normal level, the power supply quality to user improved obviously.
