A Novel Power Electronic Load Simulation Method

摘要

In this paper, a novel power electronic load (PEL) simulation method is proposed. The simulation object is three-phase phase-controlled rectifier bridge load. 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.
