Penstock Monitoring System in Active Landslide Areas
During initial planning of a high-head, five megawatt hydroelectric plant in Northern California, it was identified that the entire three-mile length of a 40 inches welded steel penstock...
New Demands for Hydro Unit Inspection and Preventive Maintenance
As the hydro industry enters the 90's, special interest has been drawn to the fundamental practice of hydro unit inspection and maintenance. New demands on hydropower equipment...
Rehabilitation of Dams, Spillways, and Hydroplants
Many older dams are in need of rehabilitation as a result of aging, deterioration, and more stringent safety standards. Concerns include deterioration of original construction materials,...
Operations and Maintenance Manual for Bradley Lake Hydroelectric Project
Bradley Lake Hydroelectric Project is located on the Kenai Peninsula of Alaska. The project consists of two 63 MVA turbine-generators fed via a single 3.5-mile-long penstock. The water...
Generation Control Methods for Operating Efficiency Improvement
One way to increase the energy production of a hydroelectric powerplant is to improve the power production efficiency, that is, obtain more energy for a given quantity of water through...
Dewatering Using a Floating Bulkhead Proves Flexible, Reusable and Cost Effective
Going beyond a traditional bulkhead dropped in place with a barge crane or crane hoist, a steel floating bulkhead was conceived to dewater powerplant intakes, gated spillway bays or outlet...
