As province attempt,after realizing independent attempt in Chongqing power network,we cry for building modern energy management system (EMS).Among them,automatic generate electricity control (AGC) is one of the most basic and the most important composing parts.Chongqing power network had built,and run a modern energy management system (EMS) in July 2000. Because this system was based on traditional power monopoly under that situation,so it isn't adaptive in power market system. Accompanying power system reformation,Chongqing power network will be merged into the middle China power network. According to national' power attempt communicating center assessing measure,Chongqing power network modulates not only network frequency but also the power of Chuan Yu-the middle China network alliance line. In Chongqing power network,because the function of AGC isn't perfect,the frame of machinery unit isn't sound,and the speed of adjusting machinery unit is slow. So it's very difficult to achieve the targets. As a result,Chongqing network is confronted with the stress of pecuniary penalty. In order to resolve this problem,from technique and management,the main contents of my paper are as follows:The traditional arithmetic of automatic generation controller and it's deficiency;the main problem and fundamental solution of the automatic generate electrical controller of Chongqing power network;(3) The solution scheme of automatic generate electrical controller of Chongqing power network under the market.Though two year's study,I analyze the design of traditional AGC and its achieving mode. I'm clear about the situation and main problem of AGC of Chongqing network,putting forward the thoughtN policymaking and technique solution. It includes:solving "excess attempt" and "defective attempt" of AGC by load prediction in extraordinary shot time,that is preceding control technique;(2) enhancing the regulating capacity and speed of AGC of Chongqing network by 5 measure;Analyzing the policymaking that Chongqing network could achieve criterion now or afterThree Gorges power station running,discussing the managing measure how to enhance regulating capability of AGC of Chongqing network .Part research fruit has been applied in Chongqing power network,it brings into important play for the safety,economy,and running high quality of Chongqing network,and avoiding pecuniary penalty with SI CHUAN-CHONG QING power connecting line.
