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。
According to the characteristics of the vibration zone of Ertan Hydropower Station, the calculation formula of the AGC area can be deduced, and the non-assignable area of the unit under different operation modes and different power heads is calculated. In the process of setting the AGC distribution load to avoid the unallocated area, to avoid the unit due to the load can not be assigned to run in the vibration zone, improve the unit operating conditions, improve the performance of the AGC system for the operation of the staff provided a reference Data and theoretical basis. At the same time, the calculation formula of the AGC distribution area of hydro-generator in two vibration zones is deduced, which has the value of application and popularization.
