考虑了长引水隧洞的管流弹性、双调压井布置、轴流转桨式水轮机桨叶和导叶的协联、PID调速器的微分整定等因素,导得了能反映综合影响的调节稳定临界曲线统一算式。并用来对有长引水隧洞混流式水轮机(带有和不带有调压井)、较短引水隧洞转桨式水轮机(带有和不带有调压井)、长引水隧洞混流式水轮机(上下游均有调压井)的五个水电站作了计算示例。可供水电站设计者和运行者处理调节稳定问题时参考。
Taking into account the long diversion tunnel tube flow elasticity, dual surge shaft layout, axial turbine blade and guide vane association, PID governor differential tuning and other factors, has been able to reflect the overall impact of regulation and stability Critical curve unified formula. It is also used for the construction of Francis turbines with long diversion tunnels (with and without surge tanks), short diversion tunnel impeller turbines (with and without surge tanks), long diversion tunnel Francis turbines Downstream surge kits) for the calculation of five hydropower stations. For hydropower station designers and operators to deal with the issue of regulation and stability reference.
