| 摘 要： | 针过石龙电站轴流转浆式水轮发电机组在甩负荷时出现抬机量过大的现象,从理论上进行了分析.通过采用重新校核、调整真空破坏阀开启力,增加补气量,及将导叶关闭由一段直接关闭改为分段关闭的方法,减小了机组甩负荷时的抬机量,保证了电站的安全运行.

| Abstract: | Taking the excessive machine lifting due to load rejection for kaplan turbine in Shilong Power station for example,this paper analyzes the reasons for the phenomenon theoretically and reduces machine lifting due to load rejection by rechecking,adjusting open force of vacuum breaker valve,adding air supply and closing entrance bucket separately instead of together,which guarantees the safe operation of power station. |
