摘　　要：在详细分析水轮机调速器液压控制系统的结构和工况的基础上 ,提出了一种新型的水轮机调速器液压控制系统 ,水轮机调速器并联型液压控制系统。它由 1个可连续调节流量的小流量阀和 1个开关型的大流量阀构成的并联系统完成自动调节控制。对它的控制策略及稳定性进行了分析 ,并对比例阀和方向阀并联系统进行了讨论。图 7表 1参In this paper, the structure and working conditions of hydraulic control system for hydraulic turbine speed governor will be studied in detail. According to this analysis, a new type sytem parallel connected hydraulic control system is employed to serve the hydraulic turbine speed governor. The control strategy and stability of this kind of hydraulic control system are discussed in this paper. Finally an example system parallel connected system with proportional valve and directional valve is discussed. Figs 7, table 1 and refs 3.
