农村电网无功优化系统的分析与实现

The Analysis and Implementation of Reactive Power Optimization System of Rural Power Grid

对农网而言,静态无功补偿常见,动态无功优化系统十分少见。通过对农网的无功优化系统的分析并实施系统改造,可以起到改善供电电能质量、提高电压合格率、减少负载总电流及电压降、改善三相不对称状况、及时消除階波的功能,并可以根据优化分析结果,对运行中的电容器投切、有载调压配变分头的调节。

Static reactive power compensation for rural electric is common,but dynamic reactive power optimization system is very rare.Through the analysis for reactive power optimization system and the installation of reactive power compensation equipment,can improve power supply quality,improve voltage qualification rate and reduce the total load current and voltage drop,improve three-phase asymmetry,timely eliminate order wave function,and can according to the results of the optimization analysis of the running capacitor,the adjustment of the on-load voltage regulator with variable separately.
