摘　　要：在新能源大规模接入的情况下,由于新能源的随机性、波动性和间歇性,火电企业为适应负荷波动,扩大生存空间,需要充分释放火电机组的调节能力。在传统的机组调峰操作中,操作量比较大,而且操作人员的误操作率较高,造成设备磨损。本文结合生产实践,提出一种发电机解列灭磁,锅炉保持燃烧,汽轮机不打闸,维持3000Rpm定速的非常规方式,有效解决汽轮机转子寿命损耗和可能的动静碰磨问题。In the case of large-scale access to new energy,due to the randomness,volatility and intermittency of new energy,thermal power enterprises to adapt to the load fluctuations,expand the living space,it is necessary to fully release the regulating capacity of thermal power units.In the traditional peaking operation,the operating quantity is large,and the misoperation rate of the operator is high,which causes the equipment wear.Based on the production practice,an unconventional method of de-excitation of generator,keeping combustion of boiler and keeping 3000Rpm constant speed of steam turbine is put forward,effectively solve the steam turbine rotor life loss and possible dynamic and static friction problems.
