国内外装有轴流转桨式水轮机的电站,都曾经发生过抬机事故:转轮和导叶被破坏、顶盖跳动、发电机转子上抬、发电机集电环被破坏等。本文对高坝洲水轮机在导叶和桨叶不协联关闭过程中,用电算法对转轮反向推力、机组转速变化、压力变化过程等进行了研究。 At home and abroad equipped with axial-flow paddle turbine power station, have been carried off the machine accident: the runner and guide vane is damaged, the top beating, the generator rotor lift, the generator collector ring is destroyed. In this paper, the high-latitude dam turbines in the guide vanes and blades are not closed during the closure process, the algorithm used on the runner reverse thrust, the unit speed changes, the pressure change process were studied.
