摘　　要：针对城市轨道交通牵引供电系统在非高峰时段功率因数低的问题,提出一种基于能馈式牵引供电装置的无功补偿方案。分析了供电系统非高峰时段无功功率较大的成因,介绍了能馈式牵引供电装置的基本结构和工作原理,并结合无功功率的分布提出了相应的无功补偿策略,最后通过一台2MW样机挂网试验验证了该补偿策略的可行性。Due to the low power factor of traction power supply system for urban rail transit in rush hours, a reac-tive power compensation scheme based on energy-feedback traction power supply system was proposed in this pa-per. The causes of the low power factor of power supply system were given, as well as the structure and working principle of the energy-feedback traction power supply equipment. A reactive power compensation strategy was pro-posed according to the distribution of reactive power. At last, a prototype rated 2MW was built and tested, and demonstrates that the reactive power compensation strategy proposed is feasible.
