目前四川省农村水电站发电机调相运行大体有两种形式:一种是发电机不带水轮机运转;另一种是发电机带水轮机运转。第一种形式发电机消耗有功少(约占5%),水轮机由于不同时运转亦不存在磨损问题,并可随时进行检修;但缺点是:甩掉水轮机后,机组惯性力矩减少,对没有阻尼绕组的小型水轮 At present, there are basically two forms of generator phase modulation operation in rural hydropower stations in Sichuan Province: one is that the generator runs without a turbine and the other is a generator runs with a turbine. The first type of generator consumes less active power (about 5%), and the turbine does not have any wear problem due to the different running time. Maintenance of the turbine can be carried out at any time. However, the disadvantage is that after the hydraulic turbine is thrown off, the inertia moment of the turbine is reduced, Winding small water wheel
