| 摘 要： | 针对影响水轮机使用寿命与运行安全的气蚀和振动问题,从经济角度出发,用惩罚函数方法,有效地避开了机组的气蚀和振动区.在水电站自动发电控制AGC中,为避免负荷调整时频繁通过气蚀和振动区,以及机组的频繁开停,将机组的安全运行区以虚拟机组形式加入电厂的AGC优化计算中.

| Abstract: | Aiming at the problems of the cavitation erosion and the vibration effecting the service life and safety for a turbine, form the economical point of view, the penalty functions have been applied to away from regions of the cavitation erosion and the vibration. In the AGC of a hydropower station, in order to avoid passing the above mentioned regions and not start stop frequently, the safety regions of a unit have been used to calculate for optimization in the station with the form of virtual unit. |

| Keywords: | Automatic Generation Control (AGC) penalty function virtual unit cavitation erosion |
