为了降低发电水耗和提高水电站的经济效益,1979年10月,我所和电厂在接近设计水头时,对该厂1、2号机作了实际协联运行和各种定奖工况的绝对和相对效率试验。试验发现1、2号水轮机的协联关系不合理,影响机组的效率发挥,经检修反复调整协联关系后,已在三个协联工况的对比性效率试验基础上,找
In order to reduce the water consumption of power generation and improve the economic benefits of hydropower stations, in October 1979, when I and the power plants approached the design head, the actual operation of the No.1 and No.2 plants of this plant and the absolute conditions of various awards were made And relative efficiency test. It was found that the correlation between No.1and No.2 turbines was unreasonable, which affected the efficiency of generating units. After repeated adjustments to the syndication relationship after overhaul, it was found on the basis of the comparative efficiency test of three synergistic working conditions
