一种改善水轮发电机组稳定性的方法

A Method of Improving the Stability of the Hydro Generating Unit

水轮发电机组流道内水压脉动是影响机组运行稳定性的重要因素之一 ,增大接力器容量可削弱机组流道水压脉动的影响 .实验证明 ,这是提高轴伸贯流机组稳定性的有效途径 .

Water pressure pulse in the water passages of the hydro generating unit is one of the factors effecting the unit stability. In order to reduce the influence of water pressure pulse in the water passages, the method to obtain higher stability of the tubular type hydro generating unit by increasing the servomotor capacity of the governor is introduced and the site tests verify its effect.
