Centralized Control System Voltage And Reactive Power Optimization Based On Ann And Es Regional Power Grid

Voltage is one of important quality index of electric power. Power loss is an important synthesis technical and economic index of power companies. In the past several years, the problem of power loss is very serious. However, reactive compensation is an effective method to save power loss. Currently, improving voltage quality and saving power loss have been job emphasis of power companies. Reactive power/voltage control in region network is researched in this paper. The characteristics of compensation devices are introduced. Reactive power/voltage control models and rules of substation are analyzed, and an optimal method based on artificial neural network is mentioned. Design idea and knowledge constitute of a multi substations reactive power /voltage coordination control expert system which make use of results of single substation reactive power /voltage control neural networks are presented. At end of the paper a region real time reactive power/voltage concentrate automation control system is introduced.
