Analysis of zero-sequence circulating current control method in parallel system of converter
摘要
Abstract
The development of new energy technology requires the power electronic equipment to increase power constantly,which leads to the generation of parallel system of power electronic equipment.In this paper,the reason of zero-sequence current of parallel converter was analyzed through the mean value model of multiple parallel converter system.Then,two methods of reducing zero-sequence circulating current were proposed.In order to further analyze the effect of the two methods,a SIMULINK simulation model was established.The simulation results show that both the PI control and deadbeat control can suppress the zero-sequence flow.But the control effect of PI control is more stable and more suitable for practical application.关键词
