Research on three-phase phase-controlled rectifier bridge load simulation method

In this paper, a novel simulation method of the three-phase phase-controlled rectifier bridge load is proposed. This method is very important for power electronic load (PEL) to test the power quality. About this content, there are few articles mentioned. Through the detailed analysis of three-phase phase-controlled rectifier bridge characteristics, a kind of load simulation algorithm is proposed. The algorithm can meet the requirements of simulation in different thyristor trigger angles. A current tracking control strategy of proportional controller and repetitive controller is put forward, which can improve the accuracy of the load simulation. Simulation and experiment verify the accuracy of the load instruction current algorithm, and the effectiveness of the current loop control strategy.
