Installation and Startup of the Idaho Falls Bulb Units
The Idaho Falls Low-Head Hydroelectric Demonstration Project consists of the redevelopment of three existing power plants using identical bulb turbines and generators. This paper summarizes...
A Marine Thruster in Small Scale Hydropower
A 70 kW hydroelectric plant utilizing a marine thruster as a turbine was commissioned in May, 1985. The thruster, the construction management, the site conditions and the testing program...
Design and Application of an Open-Loop Control System for Run of River Sites
This paper compares an open loop control system for variable geometry turbines to a closed loop system for fixed geometry turbines. The control systems were designed to operate three submersible...
Hydropower on a Wastewater Plant Outfall: Point Loma Hydro Project
The plant is on a bluff 90 feet above the Pacific Ocean where the primary treated effluent is discharged through a 2-mile-long (3. 2 kilometer) outfall pipeline. The head was previously...
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...
Operation of the Annapolis Tidal Straflo Unit
The Annapolis Tidal Generating Station, located at Annapolis Royal, Nova Scotia, is the first plant in North America to generate electricity by Tidal action. The facility, rated at 19....
North Fork Hydro Electric Power Station
Lake Hemet Municipal Water District has recently installed a hydro power station capable of producing approximately 200 KW of power during years of normal flow and 600 KW during periods...
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...
Case Study of Existing Site's Optimum Capacity
A study was performed to determine the optimum additional hydroelectric capacity for installation at an underdeveloped run-of-river hydro site. The added capacity will operate in conjunction...
Non-Federal Development at a Federal Dam: A Case Study
The 2. 8 MW Mt. Elbert Conduit Hydropower Project, developed by STS Energenics Ltd. Inc. , will begin operation mid-October, 1985. The powerhouse has been constructed and the turbine and...
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...
Uncertainty Analysis of Field Turbine Performance Measurements
This paper presents comprehensive uncertainty analyses of two different flow measurement methods for field tests on turbines. The 'water to wire' efficiency was...
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...
Rim-Drive Turbine for Low Head Applications
A turbine design and testing program was undertaken with the objective of developing a standardized turbine/generator arrangement that would be well suited to the 10 to 30 foot head range....
A Review of the Cross-Flow Turbine
The historical development of the cross-flow turbine is briefly presented together with a summary of the well-documented one-dimensional theory. Two-dimensional aspects of runner design...
Main Canal Headworks Hydroelectric Project
This project is being installed at the Dry Falls Dam, Coulee City, Washington, adjacent to the Main Canal Headworks which controls the irrigation releases to the Columbia Basin Project....
Micro PAT-Synchronous Generator Unit for Isolated Power Supply at Sultan Project Dam
The paper describes a unique application of a micro-PAT Unit installation utilizing downstream release flows for providing an isolated power supply at the Jackson (Sultan) dam in Washington...
Laser-2-Focus Flow Measurements in the Runner of a Bulb Turbine and Comparison with Calculation
Flow measurements are presented, which were carried out near and inside the 4-blade runner of an axial model bulb turbine of double adjustable type. These measurements were performed by...
