摘要
发电厂自动发电控制(AGC)由于其调节速度快、准确性高,在安装机组多的大、中型发电厂广泛运用,也取得了良好的效果。然而在实际应用中亦存在调节时机选择不合理导致有功偏差过大、参与安全稳定控制机组与联控矛盾、水电机组开停机过程中快速跨越振动区导致AGC控制偏差报警等问题,本文针对这些问题进行了分析,亦提出改进方案。
Auto Generation Control(AGC)is widely used in large and medium-sized power plants,good results have been obtained.However,there are also some problems in practical application,such as:active power deviation due to improper timing of adjustment,contradiction between security and stability control device and AGC,rapid change of active power during acrossing the vibration zone leading to AGC alarm and so on.This paper analyzes these problems and puts forward the improvement plan.
