Case Study in the Rehabilitation of a Pumped/Storage Installation - Salina Powerhouse Grand River Dam Authority
This paper presents a specific case study in the rehabilitation of a pump/turbine for the Grand River Dam Authority at its Salina plant. The study addresses problems such as cavitation...

Manicouagan 5?Additional Capacity Project
This paper, after presenting briefly the evolution of the peak demand characteristics of the Hydro-Quebec grid and what caused it, describes how newly installed capacity and equipment...

Transient Analysis of the Finchaa Hydroelectric Project
An iterative computer simulation procedure called LIQT (Liquid Transient), which performs simulations of hydraulic transients in closed conduit hydro-power systems, is used to estimate...

Turbine Conceptions for Low Heads and Their Application in US Hydro Power Stations
To improve the feasibility of small power plants standardized units were developed. The bulb turbine technology as well as the pit-type conception improve the feasibility of larger plants....

Quick Response on the Mississippi
In November 1987, the Mississippi River broke through the foundation of the St. Anthony Fall's Lower Dam Hydropower Plant. The plant's owner, the Northern State...

Preventive Maintenance: Fixing What Ain't Broke
Municipalities are often caught in the cycle of built-neglect-rebuild. For bridges, the solution is preventive maintenance: keep the bridges clean and painted, and they'll...
