This book contains English translations of 19 articles selected from the Chinese
Another Geotech Import: Deep Soil Mixing
A technique called deep soil mixing (DSM), imported from Japan, has been used to stabilize an existing dam foundation. When the Bureau of Reclamation discovered that Jackson Lake Dam had...
Capacity Increase of Multi-Jet Pelton Turbines
The recent connection to the grid of large capacity thermal stations, to meet the increasing demand, has entailed an evolution in the type of services required from storage plants with...
Maximum-Slew-Rate Nonlinear Control for Improved Transient Response in Hydrogenerators
This paper considers a linearized model for fixed blade turbines. This paper demonstrates that constant gate speed bang-bang control holds potential advantages over current control techniques....
Small Scale and Low Head Hydro Development in Canada: An Overview of Federal Activities and Policy
Through research and development, new small turbines have been tested and a Darrieus type vertical axis hydraulic turbine (VAHT) has been developed and field tested. Manuals for hydrologic...
Development of the Owyhee Dam Hydroelectric Project
The Owyhee Project Power Committee and Owyhee Irrigation District are developing the Owyhee Dam Power Plant, currently under construction in eastern Oregon. The power plant is being constructed...
Criteria for Selecting Turbine-Pumps Used in Mini-Hydro Power Units
The present paper is aimed at studying turbine-pump units operating at low heads. The proposed methodology is based on the global matching of the turbine and the pump so that both will...
Mini Hydro at the Hackett Mills Project
The project includes rehabilitation of a timber crib dam and the first use of a Right Angle Drive turbine in the United States to generate power from the 16 feet of head available at the...
Planning & Execution for Rehabilitation of Large Francis Turbine/Generator Units
This paper highlights some of the constraints in planning and execution of rehabilitation work which must be carried out within an extremely tight schedule, dictated by hydrological considerations...
Turbine Efficiency Loss Associated with Draft Tube Aeration
Draft tube aeration is one method for improving the dissolved oxygen content of hydroelectric discharges. A simple analytical procedure is presented for estimating the loss in turbine...
FEM-Flow Analysis in Hydraulic Turbomachinery Runners
Finite element calculations of the flow through distributor and runner of hydraulic turbomachines are presented. The method is quasi-3D and inviscid, but the deviations from a potential...
Francis Turbine Surge Prediction and Prevention
Every Francis turbine has some range(s) of load where the flow in the draft tube is subject to fluctuations. Various types of surge during 'steady-state' operation...
A New Turgo Turbine in China
In this paper a special runner bucket of the new Turgo turbine is illustrated and a comparison is made between the characteristics of the new Turgo and the ordinary Turgo turbine with...
