Automatic Voltage Control System Design And Realization In Nanchang Electric Power Grid

Power Systems and Electric Power Corporation to run the basic objective is the safety, quality and economic power to the users, while voltage is an important index of power quality. Use of reactive power and voltage control techniques to improve the voltage quality, reduce the reactive power flow, improve electrical power factor by the stable operation of the power system to reduce line loss and to ensure the safety of industrial and agricultural production, improve product quality, reduce electricity intensity and others have directly.Automatic Voltage Control (Automatic Voltage Control --- AVC) system-wide state of reactive power and voltage monitoring and analysis of centralized computing, from the overall perspective of the wide-area distributed reactive power optimization control device coordination, is to maintain the system voltage stability enhance the grid voltage quality and economic performance throughout the system level, to improve management of reactive power and voltage level of an important technical means.In this paper, domestic and foreign research-based, power grid as a model object of Nanchang, Nanchang automatic voltage control system network design and implementation of research testing.
