【Abstract】 The basic structure and key technologies of on on line stability control system of Central China power system are described. Based on the theory of large scale power system and real time information from EMS, the mode of hierarchical decision and hierarchical control are adopted, and the unified coordination among all of the stability control devices in whole network is implemented to attain the regional optimal control. By use of the presented system the tactic forms of stability control devices of the whole network can be refreshed within 5 to 10 minutes and the requirement of on line control is satisfied. In this paper the on line stability control project for Henan Provincial Power Network developed by Henan electric power dispatching centre and the obtained achievement from this project are presented.更多还原
