摘要
原某电厂5台巨型水轮机组自动电压控制(AVC)调节合格率基本为92%左右,近3年时间通过分析励磁系统PSS和调差以及注入式定子保护等方面对AVC调节控制的影响,调整了励磁系统调差系数,更换了适用的无功变送器等,实施后AVC调节性能月调节合格率达到了99%以上,并对某电厂优化巨型水轮机组自动电压控制(AVC)调节功能、满足要求的技术指标和调节性能取得提升的几个重要影响因素进行分析。
The former qualified regulationrate of AVC of 5 giant turbine units in a power plant is about 92%.The adjusting coefficient of excitation system has been modified and the suitable reactive power transmitter has been replacedby analyzing the influence of excitation system PSS,adjusting difference and injecting stator protection on AVC in the last three years.After implementation,the qualified rate of AVC function monthly regulation is over 99%.Finally,several important factors of optimizing AVC function in the power planthave been analyzed,which meet the requirements of dispatching,and improve the regulation performance to meet the required requirements.
