Abstract Research purposes: The reactive power compensation of urban rail transit is an important aspect of power supply system design, which is directly related to system economy and reliability. However, the current equipment selection and application in the industry have not been closely combined with engineering characteristics. Through this study, this paper proposed the principle of rational configuration of reactive power compensation devices and an optimization plan for collaborative compensation using regenerative braking devices under centralized power supply mode. Research conclusions: (1)The reactive power compensation scheme for urban rail transit needs to be designed specifically in combination with the gateway metering point and the structure of the system.(2)Based on the iterative algorithm of reactive power measurement, using multiple medium-voltage inverter-based regenerative braking devices to cooperate, the technical feasibility of realizing the precise reactive power compensation scheme in the form of fixed compensation is verified through practice, effectively realizing the reuse of equipment and reducing the investment in engineering construction.(3)The scheme of using regenerative devices for precise reactive power compensation can be applied to urban rail transit power supply system.
