以赞比亚的卡邦波水电站为例,根据引水发电系统的布置,建立包括引水隧洞、水轮机、尾水调压洞、尾水隧洞的数值计算模型,模拟在机组开机、停机、甩负荷等各工况下,整个引水系统建筑物各部位的压力、蜗壳末端最大压力、机组转速上升以及尾水调压洞最高和最低涌浪;同时,论证了将尾水调压洞模拟为尾水调压室计算所得结果的可靠性。通过水机电联合模拟,得到了更可信的调节保证参数计算值。
以讚比亞的卡邦波水電站為例,根據引水髮電繫統的佈置,建立包括引水隧洞、水輪機、尾水調壓洞、尾水隧洞的數值計算模型,模擬在機組開機、停機、甩負荷等各工況下,整箇引水繫統建築物各部位的壓力、蝸殼末耑最大壓力、機組轉速上升以及尾水調壓洞最高和最低湧浪;同時,論證瞭將尾水調壓洞模擬為尾水調壓室計算所得結果的可靠性。通過水機電聯閤模擬,得到瞭更可信的調節保證參數計算值。

Take Zambia Kabompo hydropower station for example, according to the arrangement of power generation systems, numerical calculation models have been built, which including diversion tunnel, turbine, tailrace surge holes, tailrace tunnel, and under the situation of the system on working, halting, load shedding, the operating condition of each model has been simulated, and the pressure of various parts of the building, the maximum pressure of the end of volute, the unit speed rising and the highest and lowest surge of tailrace surge hole have been calculated, as well.Meanwhile, the tailrace surge hole can be simulated as a surge chamber.Through water machine combined simulation, the more credible calculation data is obtained.
