A Mathematical Model for Traveling Screens at Hydropower Plants
Hydroelectric projects cause significant mortality to fish migrating downstream. The current method to reduce fish mortality at hydropower plants is the use of traveling screens. In this...
The Impact of Inlet Flow Characteristics on Low Head Hydro Projects
This paper discusses the intake civil designs, addressing head loss and flow distribution into the turbine intake. The impact of poor flow quality on head losses, turbine performance,...
Analysis of Hydraulic Transients for Design and Operation of Two Powerhouses in Series
The Dinkey Creek Project will be located in the southern Sierra Nevada mountains 40 miles north-east of Fresno, California, and will develop about 4000 ft of gross head with a maximum...
Design and Operation of a Differential Surge Tank
The differential type of surge tank is more effective in operation than the simple type because it reacts more quickly to load changes of all sizes. The differential tank is also usually...
Case Study: Siphon Penstock Operations
Hydroelectric power plants utilizing siphon penstocks operating near Winter, Wisconsin and at Jim Falls, Wisconsin have met or exceeded expectations after fine tuning of the vacuum and...
TBM Tunnel Friction Values for the Kerckhoff 2 Project
In the mid-1970's Pacific Gas and Electric Company began design of the Kerckhoff 2 Hydroelectric Project, which supplements the Kerckhoff 1 project built in 1919. The Kerckhoff...
