在某一水头下 ,轴流转桨式水轮机导叶开度与桨叶转角有着最优的配合关系 ,即协联关系 ,当水头变化时 ,此协联关系曲线也随着变化 ,因此实时跟踪水头变化是必要的 ,通过研究转桨式水轮机的协联特性 ,设计研制了天桥水电厂水头自动跟踪装置 ,使水轮机运行保持在协联工况 ,并对这一协联控制系统进行研究 .
Under a certain head, the vane opening angle of the impeller with axial flow and the blade rotation angle have an optimal cooperation relationship, that is, the association relationship. When the water head changes, the relation curve of the association changes with time, so the real-time tracking The change of water head is necessary. Through the research of the joint characteristic of the rotary paddle turbine, the automatic head tracking device of Tianqiao hydropower plant is designed and developed to keep the turbine running in the joint working condition and to study the synergetic control system.
