摘要
无级调速机组可以根据不同的水头选择不同的运行转速,能够明显地改善水泵水轮机的水力性能,减少振动、空蚀和泥沙磨损,提高机组的运行稳定性。为了推进交流励磁机组在国内的发展,根据抽水蓄能电站工况和无级调速机组的自身特点分析其控制策略,并依照国外某项目的参数进行仿真,通过仿真验证了所提出控制策略的正确性,为工程应用提供了理论依据。
The stepless speed regulation unit of pumped storage power station can operate under different speed according to different head. This can significantly improve hydraulic performance, reduce vibration, cavitation and sand abrasion, and improve operational stability of pump-turbine. In order to promote the development of AC excitation unit in China, the control strategies of AC excitation are analyzed based on the working conditions of pumped storage power station and the characteristics of stepless speed regulation and the strategies are simulated in accordance with the parameters of a abroad project. The proposed control strategies are verified by the simulation results.
