摘　　要：梨园电厂机组在低水头运行工况下,调速器导叶在最大开限运行时,监控系统下发的功增令存在持续累加情况,导致监控系统减负荷时出现调节速率慢、响应时间长的现象。针对以上情况进行了原因分析,改进了PGV(综合负荷给定)控制策略,并进行了试验验证,取得了良好的效果。Under the low head operating condition of generator set in Liyuan Power Plant,when governor guide vanes are operating at the maximum opening limit,there is a continuous accumulation of power increase orders issued by monitoring system,resulting in slow regulation rate and long response time when monitoring system is reducing load.This paper analyzes the reasons for above situation,improves PGV control strategy,and conducts experimental verification,achieving good results.
