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。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 price of a single air-cooled generator unit is presented based on a certain investment recovery period.
