根据二滩水电站机组振动区特性,推算出自动发电控制（AGC）不可分配区计算公式,计算出了机组在不同运行方式、不同发电水头下的不可分配区。在程序中设定AGC分配负荷时避开不可分配区,就可避免机组因负荷不可分配而运行在振动区,改善了机组运行工况,提高了AGC系统工作性能,为运行值班人员提供了参考数据和理论依据。同时,推算出了两振动区水轮发电机组AGC不可分配区计算公式,具有应用推广的价值。

Based on the vibration zone characteristic of units in Ertan hydropower station,the formula of the non-distributable zone of automatic generation control(AGC) is calculated,the non-distributable zone of units is computed under different operation modes and different water heads.The non-distributable zone is avoided in the program setting of AGC distribution load.It not only can prevent the unit from operating in the vibration zone when load cannot be distributed,but also can improve the operation condition of the unit and the performance of the AGC system.And it also provides reference data and theory foundations for operator on-duty.Moreover,the formula of AGC non-distributable zone of two vibration zone is calculated,which is worth popularizing.
