利用并联电抗器改善电压质量的分析研究

Research and Analysis of Improving Voltage Quality by Shunt Reactor

黄山电网220 kV万安变电站的110、35 kV母线电压,在一定情况下会出现偏高的问题。分析了电压偏高的原因,提出并分析比较了在不同处加装不同容量并联电抗器进行调压的方案。降压效果的实测表明,并联电抗器投入运行后大大提高了电压合格率。最后,提出了几点改进建议。

The voltage values on 110 kV and 35kV buses in 220 kV Wanan substation of Huangshan power network are higher than normal in certain circumstances. After analyzing the reason of this voltage increase, the voltage regulating schemes by installing shunt reactors of different capacity in different places are proposed and compared. The practical measured voltage reduction effect shows that the voltage quality is greatly improved after the reactors have been put into operation, and finally several suggestions are proposed.
