摘　　要：对200MW以下汽轮发电机,可通过改进转子线圈的通风结构、引线和集电环结构,达到降低损耗、提高效率的目的。并通过性能比较,证明了目前对老机组转子的改造是提高机组性能的一种有效方法。This paper explains the rotor retrofit for turbine generator of below 200 MW. The efficiency is raised and the losses are reduced through improving the ventilation structure of rotor coil and the structure of lead wire and collector ring. It is proved that this is a kind of effective method to improve the performances of generator unit for the retrofit of rotor of aging unit at present time.
