    In the analysis of stability and rapid damping conditions of hydraulic turbine control system consisting of ideal speed governor with elastic follow-up device, this article takes into account the influence of hydraulic turbine characteristics. Six slope constants are chosen for representing the turbine character influence, and they vary with the types and the operating regimes of hydraulic turbines. Vishniegrasky's diagram(third order system transients) is utilized for the determination of conditions necessary...

    In the analysis of stability and rapid damping conditions of hydraulic turbine control system consisting of ideal speed governor with elastic follow-up device, this article takes into account the influence of hydraulic turbine characteristics. Six slope constants are chosen for representing the turbine character influence, and they vary with the types and the operating regimes of hydraulic turbines. Vishniegrasky's diagram(third order system transients) is utilized for the determination of conditions necessary for half a periodic regulating process. The calculation method with an example of optimum adjustment of governor parameters(temporary statism and isodrome time constant) with different types of turbines and operating regime is described. It is considered useful for setting the electrohydraulic speed governors, which have been widely employed in many hydropower plants.

    本文在有软反馈的理想调速器组成的水轮机调节系统的稳定性和快速衰減条件分析中,考虑了水轮机特性的影响.这种特性的影响以水轮机六种斜率常数来表征,而且随水轮机型式和运行工况不同而异。调节过程的快速衰减条件是根据所论系统的特征方程的常系数由维希尼格拉特斯基图来确定的.文中叙述了按水轮机不同运行工况进行调速器参数(暂态调差率和缓冲时间)最佳整定的计算方法和计算例。这对近来开始广泛采用的电液调速器运行有一定实用意义.

    The pressure tailrace tunnel of Jingpo Hu underground hydropower station is 7.8m in designed excavation diameter, has a length of more than 40m atits lower end passing through the strata of Tertiary formation which are softand liable to be weathered,and the rock surrounding the tunnel is of lowstability (Fig. 1). Shotcrete support experiment was carried out in theexperimental tunnel in July 1973. It proved that the application of shotcretefor temporary support can give good results in quickly sealing up the sur-rounding rock from weathering and in reducing the rock deformation. Theadoption of shotcrete support in such strata has also rendered economic benefitsand proved itself to be a good construction method.

    镜泊湖地下水电站的圆形有压尾水隧洞出口段,设计开挖直径为7.8米,其中长40余米一段穿越软弱易风化的第三纪地层,围岩稳定性很差。1973年7月进行了试验洞的开挖和喷混凝土试验,9月开始施工。实践证明对半胶结、软弱易风化的第三纪地层采用喷混凝土加固围岩,能有效地限制围岩变形发展,具有明显的经济意义,是一种较好的施工方法。
