Abstract Aiming at the power flow calculation and parameter design in the power supply system (the bidirectional converter device is the only converter), this paper establishes a power flow calculation model of urban rail power supply system considering the capacity constraint of the bidirectional converter device. According to the power flow calculation algorithm, a parameter design strategy of the bidirectional converter device based on the improved brute force search algorithm is proposed, which considers the splitting of each traction substation (TS). In the iteration, to obtain the limit solution set, the capacity, droop rate and no-load voltage are divided into three layers, and the results are based on the simulation without considering the capacity constraint of the bidirectional converter device. The actual case is studied. After considering the capacity constraint of the bidirectional converter device, the peak output power of TS is controlled, and the adjacent TSs can provide power support. The search number of the proposed strategy is 1.63% of the traditional brute force algorithm. In the example case, the train is 6B marshalling with the maximum speed of 80km/h, and the minimum capacity of the bidirectional current converter in the limit solution set is 7MW.

Key words： Bidirectional converter device parameter designing enhanced brute force capacity constraint
