Description
technical field [0001] The application belongs to the technical field of urban rail transit, and in particular relates to an optimization method for an urban rail regenerative braking energy inverter feedback system. Background technique [0002] The general environment of rail transit is facing high requirements for energy saving, emission reduction and sustainable development. "Installing regenerative electric energy absorption devices in traction substations can improve the efficiency of regenerative braking of trains, reduce operating costs with less operating electric energy, and reduce atmospheric pollution." The design concept of "pollution" has been paid more and more attention in the construction and operation of rail transit at home and abroad. How to reasonably select the constant capacity and location scheme of the inverter feedback system in combination with the actual conditions of the line and the characteristic parameters of the train is very important.
