摘要
为实现地铁交流供电系统无功平衡,以广州地铁18号线为例根据线路拓扑结构,分析造成无功过剩的原因,计算该线路供电系统的无功水平,考虑线路中无功补偿装置的补偿容量和补偿方式等因素,提出基于枚举法和粒子群算法的供电系统无功补偿方法,给出无功补偿策略。结合地铁18号线的线路数据进行仿真,结果表明,通过以上方法提出的无功补偿策略可使供电系统无功得到较好的平衡。
To realize reactive power balance in the power supply system of Guangzhou Metro Line 18,the causes of excess reactive power were analyzed based on the line's topology.The reactive power level of the line's power supply system was calculated by considering the compensation capacity and compensation mode of the reactive power compensation device in the line.A reactive power compensation method was proposed based on the enumeration method and particle swarm optimization algorithm,along with a reactive power compensation strategy.Using data from Line 18,simulation results demonstrate that the reactive power compensation strategies proposed by the aforementioned methods balance the reactive power of the power supply system.
