摘要(Abstract):
针对含小水电配电网长线路所存在的电压质量问题,以浙江青田高市175线为研究对象,提出了利用双向馈线自动调压器和线路自动无功补偿装置相结合解决低电压问题的方法。实际运行结果表明,该方法能有效改善枯水期及负荷较大时的调压效果,提高电压质量。
Aiming at voltage quality on long lines of distribution networks of small hydropower stations, the paper takes line 175 of Gaoshi in Zhejiang as a research object to propose a solution combining bidirectional feeder automatic voltage regulator(AVR) with automatic reactive power compensation device to low voltage. It is proved by actual operation that the method can effectively improve voltage regulation in low flow period and large load to enhance voltage quality.
