摘　　要：秦山核电厂330 MW级核电机组设计寿命30年,机组1991年12月并网发电。2018年,为配合核电机组延寿工作,秦山核电厂开展了发电机增容改造工作。原双水内冷发电机铭牌功率为330 MW,经过改造提升至350 MW。文章从发电机定、转子两方面分析,介绍发电机改造中的定转子改造工艺,最终通过改造后的发电机运行效果来证明改造的成功性。The design life of the 330 MW Qinshan nuclear power plant is 30 years,which was put into operation in December 1991.In 2018,the retrofit of the generator capacity carried out in Qinshan NPP to support the life extension of the nuclear power plant.The nameplate power of the original double water cooling generator is 330 MW,which was raised to 350 MW after the upgrading.This paper analyzes from two aspects of the stator and rotor,introduces the stator and rotor upgrading process in the generator upgrading,and finally proves the success of the upgrading through the operation effect of the transformed generator.
