低压配电网无功补偿方式及优化研究

Research on Reactive Power Compensation Mode and Optimization of Low Voltage Distribution Network

目前,无功补偿主要集中在中高压配电网,低压配电网补偿较少,导致低压配电网的线损增加,降低电网的输电电压,减少运行的经济效益.对低压无功补偿方式进行比较,阐述'2/3法则'的低压配电线路无功优化模式,并论述该法则的最优配置方法.研究结果显示,'2/3法则'显著改善低压配电网无功补偿的效益.

At present,reactive power compensation is mainly concentrated in medium and voltage distribution networks.The compensation of low voltage distribution network is less,resulting in increased line loss of low voltage distribution network,lowering transmission voltage of power grid and reducing economic benefits.The low-voltage reactive power compensation method is compared,and the“two-third rule”low-voltage distribution line reactive power optimization mode is described,and the optimal configuration method of the law is discussed.The research results show that the“two-third rule”significantly improves the efficiency of reactive power compensation in low-voltage distribution networks.
