江西电网无功平衡与调压计算分析

根据江西电网结构特点,分东、西、南、北、中5个区,进行了无功分层分区平衡计算,分析了江西电网无功补偿的现状和充裕度。利用四种负荷水平,对江西电网常见运行方式进行了调压计算。进而揭示了江西电网电压无功运行的特点。大负荷方式下,全网无功基本平衡,但分布不均衡;低电压问题逐步缓解,但末端地区在特殊方式下,低电压问题仍可能发生;高电压问题越来越突显,已成为调压的主要矛盾。

Analysis on Reactive Power Balance and Voltage Regulation Calculation

According to Jiangxi Power Grid structure, Jiangxi grid is divided into five areas. Then through reactive power balance calculation, status and margin of Jiangxi grid are analyzed. Voltage regulation is carried out under normal operation by using four loads to review characteristic of Jiangxi grid reactive operation. Under the large load, power grid realizes reactive power balance with unbalanced distribution. And low voltage will occurred in special mode in end areas while high voltage has become the severe problem.
