微电网中电力电子变压器的电压质量控制措施探折

Voltage Quality Control Measures of Power Electronic Transformer in Microgrid

电力电子变压器(PET)中含有多个直流环节,能够有效隔离微电网和主电网之间的频率和电气。面对大量的分布式能源入网和负荷的多样化需求,微电网面临的不稳定因素越来越多,而PET的电压质量直接影响整个微电网的稳定运行效率。因此,就微电网中PET的电压质量控制措施展开探讨。

The power electronic transformer(PET) contains multiple DC links,which can effectively isolate the frequency and electricity between the microgrid and the main grid. With the large amount of distributed energy access to the network and the diversified demands of the load,the unstable factors facing the microgrid are increasing. The voltage quality of PET directly affects the stable operation efficiency of the entire microgrid. This article discusses the voltage quality control measures of PET in the microgrid.
