摘要：

作为水电站中至关重要的组成部分,水轮机调节系统运行的正常与否直接关系到机组的安全与稳定。引水系统结构的复杂多样,不同类型的引水系统对水轮机调节系统的影响存在差异。文中首先在单压力引水管系统中,通过设置不同水击条件来分析系统相关参数的变化情况,再对单压力引水管系统和引水隧道-调压井-压力引水管系统做空载和小负荷扰动仿真对比。仿真结果表明,由于引水系统结构类型存在差异,在系统改变运行状态的初期,系统相关变化参数差异很大,但最终仍能趋于稳定。

Abstract:

As one vital component of a hydropower station, the normal operation of the turbine governing system is directly related to the security and stability of the hydro generator unit. Due to the complex and diverse structure of the diversion system, different types of diversion systems have different effects on the hydraulic turbine governing system. In this paper, the changes of relevant parameters of the hydraulic turbine governing system were analyzed by setting different water hammer conditions in the hydraulic system model of individual penstock. Then, the parameter waveforms of the hydraulic system model of individual penstock and the hydraulic system model of surge-penstock were compared under the simulation test of no-load and small-load disturbance. The simulation results showed that the relevant parameters were different at the initial stage of the system change operation because of the difference in the structure type of the diversion system, but it could stabilize in the end.

Key words: diversion system structure, hydraulic turbine governing system, surge tank, diversion tunnel, load fluctuation, simulation comparison
