基于“两个细则”的AGC控制优化案例

Case Optimization of AGC Control Based on"Two Detailed Rules"

在修订华中地区“两个细则”之后,大唐国际石柱发电公司1号机组经常性无法满足现有的AGC日均综合性能指标。针对这一问题,对该公司的AGC进行了深入分析,总结了AGC日均综合性能指标不合格的关键原因,并通过优化机组阀门曲线和AGC相关控制逻辑,成功解决了问题。相关分析与实践为类似条件下的AGC控制优化提供了参考。

After the revision of the"two detailed rules"in Central China region,Datang International Co.,Ltd.Unit 1 was often unable to meet the existing AGC daily average comprehensive performance indicators.This work focused on that anomaly and conducted in-depth analysis on the AGC control.The key reasons for the unqualified daily comprehensive performance indicators of AGC were explored,and the anomaly was successfully handled by optimizing the unit valve curve and AGC related control logics.The analysis and practice of this work provide useful information for AGC control optimization under similar conditions.
