电网双电压等级潮流约束下的水电站AGC功能策略设计

Design of station AGC function strategy hydroelectric power grid double voltage current constraints

本文主要针对国内一大型水电站AGC成组运行有功策略分配原则、220kV系统与550kV系统联络变4号主变压器不能过载运行,将4号主变压器功率纳入3号机组可调范围计算策略以及对多台机组成组下其组合振动区模型建立的方法进行了阐释,并对AGC投入的安全策略进行了分析。这可以对其他电站AGC策略设计提供相关参考。

This paper mainly for the domestic large-scale AGC group running active strategy allocation principle,220kV system and 550kV system of hydropower station with #4 main transformer cannot overload operation,the main transformer #4 pow-er into #3 machine adjustable range as well as the calculation method of multi machine group composed of the combined meth-od to establish vibration model are explained the security strategy,and analyzes theAGC investment.This can provide reference to the design of other powerr plant AGC strategy.
