Electrical and Mechanical Design, Commissioning, and Performance of the Moose River Hydroelectric Project
The Moose River Hydroelectric Project is a single-unit run-of-river hydroelectric facility located near Lyonsdale, New York, and was developed by a private firm. The generating equipment...
Devil Canyon Powerplant Enlargement Project: Electrical Design Problems and Challenges
Devil Canyon Powerplant is a hydroelectric plant facility of the huge California Water Project. This powerplant is located 5 miles north of San Bernandino. It is currently being enlarged...
Torsion Rigid Gates and Their Hoisting Mechanisms
In Europe, installation of modern, steel, 'torsion-rigid', radial (tainter) gates and flaps, operated by one or more hydraulic hoists usually situated at the...
Critical Features of Custom Design Hydro Gates
Large hydro gates are custom designed to suit each particular installation. To prevent overlooking a feature that could lead to future problems, a check list of the numerous features should...
Crest Gates Design for Upper Mechanicville
This paper describes the design of flap-type spillway crest gates for the Upper Mechanicville Project, located on the Hudson River near Mechanicville, New York. These gates are being provided...
Oil Hydraulic Design for Turbine Control
The paper addresses three areas of Oil Hydraulic Design for Francis and Kaplan Turbines: smart accumulator condition sensors, high flow servo logic, and high pressures Wicket Gate cylinder...
Considerations to Be Taken in the Design of Speed Increasers for Hydroturbine Service
The paper discusses the incorporation of a speed increaser specification that is primarily functional yet one that will address the cost, reliability, efficiency, and life requirements...
Vibration Problems of Penstock Piping for a Vertical Tubular Hydraulic Turbine
Excessive vibration amplitudes were experienced in the vertical gated tubular units at the Great Falls Hydroelectric Project located in the City of Paterson, New Jersey. Vibration amplitude...
Turbine Runner Procurement for the Robert Moses Niagara Power Plant Upgrade
Procurement of the new runners involved the selection of two manufacturers who have entered into a design competition in which competing models will be tested in an independent hydraulic...
Development of High Specific Speed Pump-Turbines
The operational range of pump-turbines is continually increasing, especially in the direction of high specific speed installation. In this context, high specific speed refers to units...
Hydro Turbine Submergence
The elevation of a hydro-electric turbine above or below tailwater is based on hydraulic model studies to determine the critical sigma, defined as the ratio of barometric pressure plus...
Design Data of Kaplan and Bulb Turbine Units
Some basic statistical data covering geometrical and energy parameters for Kaplan and bulb turbine units are presented. These data are further compared as specific rations for both units,...
