摘　　要：本文介绍了某天然气电厂60MW联合循环机组AGC系统的实现概况。通过modbus协议实现了DCS和Mark-V的通讯以及省电网调度中心和DCS的通讯,设计出了负荷分配和控制的策略,并给出了控制sama图,完成了厂内的负荷摆动试验以及和省电网调度中心的联调试验。AGC试验负荷曲线和结果分析表明,该系统实现了联合循环机组发电自动控制的功能,确保了该电厂如期投入商业运行。This paper introduces the basic control system in a specific Zhejiaug gas power plant. It summarizes the problems encountered during AGC operation from communication between the DCS and Mark - V, also the communication between the control center of the grid and the DCS, a load attribution strategy was designed, which including the Sama control figure. According to the analyses of AGC test result, this system enhancing the units to realize AGC function and be put into run on time.
