摘要
低励动作导致自动电压控制(AVC)子站系统退出,影响电厂安全、经济运行。本文结合低励限制原理与低励修正依据,讨论低励修正对低励限值及自动电压控制-有功无功(AVC-PQ)定值的影响,通过分析低励修正的工程实测数据,总结合理的低励限值与AVC-PQ定值的设定策略,并通过专项试验验证其效果,在工程应用方面为电厂AVC子站系统运行优化提供有效参考。
Low excitation action leads to the exit of automatic voltage control(AVC)substation system,which affects the safe and economic operation of power plant.Based on the principle of low excitation limit and the basis of low excitation correction,this paper discusses the influence of low excitation correction on low excitation limit and AVC-PQ setting.Through the analysis of the measured data of low excitation correction,the reasonable setting strategy of low excitation limit and AVC-PQ setting is summarized,and its beneficial effect is verified through special tests.In the aspect of engineering application,it provides an effective reference for the operation optimization of power plant AVC substation system.
