我国蕴藏着众多适于冲击式水轮机组开发的水力资源,但由于大容量冲击式水轮机和调节控制系统的研究制造与核心技术主要掌握在少数欧美水电设备制造商手中,限制了其大规模开发利用。为保证研制的冲击式机组运行的高可靠性、高性能指标、高效率运行以及采购设备的高性价比,总结了多年来冲击式水轮机调速器研究成果与实践经验;通过首次在大型多喷嘴冲击式水轮机的控制中引入机组特性曲线因素、开创性地在电气调节器中采用3个CPU的系统方案和研发新型冲击式水轮机折向器控制装置等方法,研制并投运了特大型多喷嘴冲击式水轮机调速系统,取得了良好的经济效益和社会效益,能为特大型多喷嘴冲击式水轮机与调速系统的选型、设计、规范和应用提供技术支撑。
Abstract
China is abundant of hydraulic energy resources suitable for the development of impact turbine units. The core technologies of developing and manufacturing are mainly in the hands of a few European and American hydropower equipment manufacturers, hence having limited the development and utilization of large-capacity impact turbine and regulation control system. On the basis of summarizing the research and practice experiences, we propose an innovative scheme of adopting three CPUs in the electrical regulator, and a control device of impact turbine diverter by introducing the unit characteristic curve factor into the control of large multi-nozzle impact turbine for the first time. By putting into operation this speed regulating system, we have obtained good economic and social benefits. This research is expected to be conducive to the type-selection, design, standardization and application of extra-large multi-nozzle impulse turbine.
