1962年,在湖南省王家厂水电站采用水阻抗代替调压室,其投资约占调压室的1/3.此后,单机容量500千瓦以下的小型水电站,使用水阻抗作防飞逸措施比较普遍.以下介绍用水阻抗装置代替调压室的原理、设计方法和运行效果.一水阻抗装置代替调压室的基本原理水阻抗代替调压室的基本原理是,当机组甩负荷,发电机定子有功功率消失的同 In 1962, the water resistance of Wangjiadong Hydropower Station in Hunan Province replaced the surge chamber, which accounted for about 1/3 of the surge chamber. Since then, the use of water resistance as an anti-blow-out measure has become more common in small-scale hydropower stations with a capacity of 500 kW The following describes the principle of water resistance device instead of surge tank, design methods and operating results. A water resistance device instead of the basic principles of surge tank Water resistance instead of surge chamber basic principle is that when the unit load rejection, generator stator active The same power disappears
