摘　　要：为适应国产三缸三排汽200 MW汽轮发电机组全面技术改造的需要, 广东省沙角A电厂分别于2000年和2002年对一期3台200 MW机组中的2号和3号汽轮机进行了三缸通流改造, 同时对原发电机变压器组也进行了改造, 使机组增容至220 MW。为此, 对其发电机变压器组增容的情况进行了评估分析, 并对相关设备进行了改造。实际运行表明: 改造后发电机变压器组各项指标均在运行规程规定范围内。To meet the needs of overall technical reconstruction on Chinese-made 200 MW three-cylinder triple-flow turbo units,Unit 2 and Unit 3 steam turbines in the first phase project of Shajiao A Power Plant underwent three-cylinder throughflow transformation in 2000 and 2002 respectively.The generator-transformer units were also reconstructed so as to raise the capacity of the units to 220 MW.Evaluation analysis was made in this regard and relevant equipments transformed.Operation results show that all indices of the transformed generator-transformer units satisfy the corresponding operation code.
