Research of Reactive Power Compensation Optimization on Power Network Distribution Feeder

为解决电力系统无功规划设计和建设管理工作中存在的无功电源容量缺额大、功率因数低、线损率高、设备使用效率低、电压质量差等问题,根据配电网无功补偿的研究和现场应用现状,结合配电网的结构,针对线路负荷均匀分布与非均匀分布状态下并联电容器的最优补偿容量和最佳安装位置策略进行了较为系统研究,在分析并联电容器实现无功补偿的基础上,构建了实际模型,为解决相关问题提供了依据,具有一定的实际应用价值。

It can realize reactive power compensation by installing shunt capacitor on distribution feeder. It can reduce the power loss, increase transmission ability of power network and utilization ratio of equipment ,increasing the economic benefit of reactive power compensation devices, especially on the long distribution feeder. Based on the situation of regctive power compensation and distribution network＇s structure,the paper studies the optimum location and capacity of shunt capacitor when the load of distribution feeder is uniform and non-uniform. Based on analysed correlative factors of reactive power compensation by installing shunt capacitor ,the paper designs relative model and calculates it,which provids reference for correlated problems.
