二滩水电厂是二十世纪投产的国内最大水电站,担任着川渝电网的调频调峰任务。二滩水电厂自1998年首机发电并同步实现计算机监控,其监控系统有自己的一套相对独立的闭环调节程序及 AGC/AVC 程序,它与调速器、励磁自身闭环调节互为备用,且在发电初期调速器、励磁自身闭环调节程序还没有调试修改好的情况下运行工作在远方、手动、闭环调节投入方式下,用监控的闭环调节程序增/减负荷、调节频率、电压发挥着重要的作用,在调速器、励磁自身闭环调节程序调试好以后与调速器、励磁自身闭环调节程序互为备用。随着 AGC/AVC 的调试成功,二滩水力发电厂的自动化水平又上了一个台阶。它将调速器、励磁与计算机监控有机的结合起来,使运行人员可以在中控室计算机上手动增减负荷或者投入 AGC/AVC 自动实现调频调峰。
Ertan hydropower plant was put into operation in the twentieth century the largest hydropower station, as the Sichuan-Chongqing power grid frequency modulation peak task. Ertan hydropower plant first generation of power generation and synchronization of computer monitoring since 1998, the monitoring system has its own set of relatively independent closed-loop adjustment program and AGC / AVC program, which with the governor, the excitation of their own closed-loop regulation of each other as a backup, And in the early stage of power generation governor, the excitation of its own closed-loop adjustment program has not been debugged to modify a good case of work in the far, manual, closed-loop adjustment input mode, with the monitoring of closed-loop adjustment program increase / decrease load, adjust the frequency, voltage play An important role in the governor, the excitation of its own closed-loop adjustment process debugging and governor, excitation of their own closed-loop adjustment program each other as a backup. With the successful commissioning of AGC / AVC, the automation level of Ertan Hydropower Plant has reached a high level. It combines the governor, excitation and computer monitoring organically, so that operators can manually increase or decrease the load on the computer in the control room or automatic frequency modulation peak shaving AGC / AVC.
