基于遗传算法的低压配电系统无功补偿方法研究

Research on Reactive-Power Compensation Method in Low Voltage Distribution System Based on Genetic Algorithm

提出了一种基于遗传算法进行低压配电网动态无功补偿的方法,解决由于中性线断线造成中性点位移的问题。算例表明,应用该方法进行无功补偿,可使负载三相电压与额定电压的偏差控制在±5%内,优化负载运行条件。

In low voltage three-phase four-wire distribution system,the neutral-point would be displaced,three-phase voltage would be severely out-of-balance,the normal working of load would be influenced,even the electrical equipment would be damaged.A dynamic reactive power compensation method was presented to solve the neutral-point displacement because of neutral wire breaking.The calculating case indicated that the deviation between the three-phase voltage and rated voltage would be controlled in the acceptance range of-5% to ＋5% by this compensation method and the load operating condition would be optimized.
