The invention discloses an urban rail transit main substation power supply method based on an energy router. The method specifically comprises the steps that the energy router is composed of two AC/DC converters, two DC/DC converters and corresponding controllers; two medium-voltage buses in an urban rail transit main substation are connected to a direct-current bus through an AC/DC converter, and an energy storage system and a photovoltaic power generation system are flexibly interconnected and connected to the direct-current bus through a DC/DC converter; the controller is connected with the signal acquisition device and each switching device, and the functions of storage and scheduling of tractive power supply system return energy and photovoltaic power generation energy and voltage adjustment and power factor correction of two sections of medium-voltage buses of a main substation are achieved through a specific control algorithm. According to the invention, the functions of active power fusion, reactive power compensation, photovoltaic absorption and the like can be realized, and the capacity constraint of each converter is satisfied; and the construction cost is low, and the method is suitable for new line construction and existing line reconstruction.

    本发明公开了一种基于能量路由器的城市轨道交通主变电所供电方法,具体为:能量路由器由两个AC/DC变换器和两个DC/DC变换器及相应控制器构成;城轨交通主变电所中两段中压母线经过AC/DC变换器联结于直流母线,储能系统和光伏发电系统通过DC/DC变换器柔性互联联结于直流母线;控制器与信号采集装置和各开关器件相连,通过具体的控制算法实现牵引供电系统返送能量和光伏发电能量的存储与调度、主变电所两段中压母线的电压调整和功率因数校正功能。本发明可实现有功融通、无功补偿、光伏消纳等功能,并满足各变换器的容量约束;还具有造价低、适用于新线建设和既有线改造等优点。
