| 摘 要： | 300MW级发电机普遍采用水氢氢冷却方式，全空冷方式发电机由于辅助系统简单，在发电厂运行、维护及安全等方面有着明显的优点，但亦存在着投资较高、效率略低的问题。通过对空冷发电机及水氢氢冷却发电机的技术经济指标比较，提出了单台空冷发电机基于一定寿命周期的边界价格。

| Abstract: | Compared with the normally adopted water-hydrogen-hydrogen cooled generator with a capacity of 300 MW,the air-cooled generator with simpler auxiliary systems has a lot of remarkable advantages in safety operation and maintenance for power plants.However,the air-cooled generator has also shortcomings,such as higher costs and lower efficiency.Technical and economical comparisons are made between the 300 MW air-cooled generator and the 300 MW water-hydrogen-hydrogen cooled generator,and the estimated marginal ... |
