摘要
在我国科学技术发展中,增加了对电力的需求,电力系统的电力电子化得到了迅猛发展,以适应时代发展的要求。在研究电力电子变压器中,拥有一定自平衡能力的自平衡式电力电子变压器得到发展和应用,成为配电网中的新式能量媒介。相比普通电力电子变压器,自平衡式电力电子变压器的优点是灵活可控、具有较高的功率密度,能对配电网中的不平衡状态有较好的应对。因此,主要介绍自平衡式电力电子变压器的内涵,并分析具体的控制方案。
In the development of science and technology in China, the demand for electricity is increased, electric power system has also been developed rapidly to meet the requirements of The Times.In the research of power electronic transformer, self-balancing power electronic transformer with certain self-balancing ability has been developed and applied, which has become the new energy medium in the distribution network.Compared to ordinary power electronic transformer,the advantages of self-balancing power electronic transformer are flexible and controllable, with high power density, which can deal with the imbalance in the distribution network better.This paper mainly introduces the connotation of self-balancing power electronic transformer and analyzes the specific control scheme.
