【Abstract】 Considering the advantages and disadvantages of the traditional reactive power compensation device and static var generator as well as the coal mine load characteristics, this paper put forward two stages of reactive power optimization method which is bases on static var generator SVG and capacitor for reactive power optimization of distribution network. Two stages of reactive power optimization method is respectively based on active network loss and voltage deviation as objective function. The positions and capacity of compensation is determined by the sensitivity method and the improved PSO. The calculation results of the actual power system show that the loss of distribution network and voltage levels improved significantly. And the method is flexible, efficient, and easy to implement.更多还原
