电网模拟器的技术现状与发展

Current Status and Development of Grid Simulator Technology

本文首先总结了国内外关于电网模拟器的研究现状,然后从电网模拟器的拓扑结构与控制策略两个方面,讨论了三相分离型、基谐分解型、多电平基谐分解型、多电平DC-DC型四种拓扑结构和双闭环PID控制、比例谐振控制、重复控制、模糊控制、滑膜控制五种控制策略,并提出下一步的研究重点,对今后电网模拟器的研究具有一定参考价值。

This paper first summarizes the research status of grid simulators at home and abroad,and then discusses the three-phase separation type,the fundamental harmonic decomposition type,the multi-level fundamental harmonic decomposition type,and more from the two aspects of the topology and control strategy of the power grid simulator.Level DC-DC type four topology and double closed loop PID control,proportional resonance control,repetitive control,fuzzy control,synovial control five control strategies,and put forward the next research focus,the research on the future grid simulator has Certain reference value.
