基于调速器功率闭环模式的AGC性能优化

AGC Performance Optimization Based on Governor Power Closed-loop Mode

发电厂自动发电控制(AGC)调节速率和调节范围直接影响电网电能质量.文章介绍了董箐发电厂AGC调节速率、调节范围现状,分析了调速器系统开度模式下监控闭环调节和运行人员开机组合方式不科学对AGC调节速率和范围的影响,通过对调速器功率模式的研究和探索,对调速器系统控制模式实施技术改造,并通过改造后运行数据进行校验,有效改善了AGC调节速率和响应精度.

The adjustment rate and adjustment range of automatic generation control(AGC)in power plants directly affect the power quality of the power grid.This paper introduces the current situation of AGC adjustment rate and adjustment range of Dong Qing Power Plant,and analyzes the unscientifi c effect of the combination of monitoring closed-loop adjustment and operation personnel startup in the opening mode of the governor system on the AGC adjustment rate and range.The research and exploration of power mode,the technical transformation of the governor system control mode,and through the operation data after the transformation to verify,effectively improve the AGC regulation rate and response accuracy.
