为实现广州地铁18号线供电系统无功平衡，根据线路拓扑结构，分析了造成无功过剩的原因，计算了该线路供电系统无功水平，考虑了线路中无功补偿装置的补偿容量和补偿方式等因素，提出了基于枚举法和粒子群算法的供电系统无功补偿方法，给出了无功补偿策略。结合18号线线路数据进行仿真，仿真结果表明，通过以上方法提出的无功补偿策略使得供电系统无功得到了较好的平衡。

In order to realize the reactive power balance of the power supply system of Guangzhou Metro Line 18, according to the topology of the line, the causes of excess reactive power are analyzed, the reactive power level of the line power supply system is calculated, and the compensation capacity and compensation mode of the reactive power compensation device in the line are considered. The reactive power compensation method based on enumeration method and particle swarm optimization algorithm is proposed, and the reactive power compensation strategy is given. Combined with the data of Line 18, the simulation results show that the reactive power compensation strategy proposed by the above methods makes the reactive power of the power supply system get a good balance.
