针对1洞多机抽水蓄能电站水力机组过渡过程调节保证计算中相继甩负荷对尾水进口压力的影响问题,通过对某抽水蓄能电站输水系统洞径组合的比选,得出不同甩负荷形式对尾水进口压力影响程度不同,先甩N-1台机组、后甩尾水管道最长的1台机组尾水进口压力最危险;不同输水系统洞径对改善尾水进口压力的影响程度也不同。
Aiming at the influence of successive load rejection on the inlet pressure of tailrace in the regulation and calculation of the regulation of the transient process of a hydroelectric generating set in a 1-hole multi-machine pumped storage power station, different rejection The impact of the load form on the tail water inlet pressure is different from that of the first rejection of N-1 units, and the longest tail-water inlet pressure of the tail-watering pipes is the most dangerous. Different diameters of the water conveyance systems can improve the inlet pressure of the tail water The impact is also different.
