大型国外水电站水轮机调速器仿真试验研究

Simulation Test Research on Hydraulic Turbine Governor of Large Foreign Hydropower Station

本文针对国外大型水电站卡里巴南岸扩机工程调速器稳定性分析要求,采用物理及数字的混合仿真方法,利用现场调速系统及导叶接力器等真实设备,对水轮机及引水系统、发电机及电网系统进行了建模,并将模型与现场设备有机结合,开展了机组开机、空载扰动、一次调频、甩负荷、孤网调节等现场模拟试验,最后对比最新行业标准对试验结果进行分析,测试验证了卡里巴调速系统的性能和功能,为水轮机调速器的仿真及稳定性分析提供了较重要的参考。

In this paper, aiming at the requirements for stability analysis of the turbine governor of Kariba South Extension station, adopting the hybrid simulation method of physical and digital, using the field governor system and guide vane servomotor equipment, The turbine and water diversion system, generator and power grid system were modeled through simulation equipment. Combining the model with field equipment, field simulation tests of unit startup, no-load disturbance, primary frequency modulation, load rejection and isolated network regulation were carried out. Compared with the latest industry standards, the test results are analyzed, and the performance and function of the system are verified. It provides a more important reference for the simulation and stability analysis of hydro turbine governor.
