The water-cooling system is very important for the safe operation of generator. The water leakage detection of the system is typically a problem of weak signal extraction under strong disturbances.
发电机内冷水系统是发电机组安全运行的一个重要组成部分，其渗漏监测是在强干扰下弱信号的识别问题。

When natural wind is weak, the wind helping machine can be started to increase wind speed, so as to ensure that electricity producing quantity of the generator is stable.
若自然风弱，可开启助风机加强风速，以保障发电机产电量 的稳定。
