The Research on Key Technologies of Power Quality Comprehensive Control In Complex Distribution Network

摘要

As new types of power sources and loads such as distributed photovoltaic and electric vehicle charging facilities are connected to the distribution network,the distribution network has become more variable and complex,and the simple distribution network has evolved into a complex distribution network.The access of new elements,especially the application of power electronic devices,has a great impact on the power quality of the distribution network.The technical framework of power quality comprehensive management of complex distribution network is proposed,and the corresponding technical route is put forward from three aspects:the influence of power electronic equipment application on power quality of distribution network,power electronic equipment modeling of distribution network,flexible monitoring of power quality and rapid control.
