Power quality of network was improved via delicacy management method

Voltage was an important index of power quality of network. In order to improve the power quality of network, Jiangsu Yixing Electrical Supply Co., Ltd relies on centralized control system for voltage and reactive power optimization, through comprehensive analysis about the eligible rate of busbar voltage, the management process of the eligible rate of busbar voltage of transformer substation was improved, and a series of analysis control tactics about the eligible rate of busbar voltage was formed. The level of management on voltage was improved further, through converting it into pre-control after the problem happens. This achievement was awarded the golden medal by the national quality inspection association, which has a certain promotional value.
