Rain Data Telemetry for Operation of a Hydro-Reservoir
The Collywobbles hydro-electric station operates 42MW with very little river storage. Raindata is collected from 11 gauges distributed in the 5000 km**2 catchment and telemetered to a...
A Case Study of Hydropower Operation Based on Runoff Forecast
The intent of this paper is to outline a forecast approach developed to enable the operation of power storage projects, and to illustrate from employing the approach that overall system...
Modern Technology in an Ancient Environment?The Answan II Power Plant
The Aswan II power plant is located at the old Low Aswan Dam in Southern Egypt. This dam was constructed in the early years of the century in order to provide irrigation water for cash...
The Design of the Outlet for the New Koepchenwerk Pumpstorage Plant
The Koepchenwerk Pumpstorage Plant (1930) is going to be replaced by a new plant with a 150 MW Pumpturbine in a shaft. This paper explains the reasons for this replacement and gives a...
Civil Design of Underground Hydro Power Projects
Various reasons exist for the development of underground schemes. Limited space at dam sites in deep and narrow river valleys makes it favourable to separate the power house from the dam...
OK Menga Hydroelectric Project, Papua New Guinea
The Ok Menga project, currently under construction, consists of a run-of-river intake underground concrete and steel lined power conduit surface powerhouse with two 25 MW units and a 132...

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...
Development of Three Systems Operated Rev. Pump Turbine
In order to represent the development of reversible, single stage pump turbines in Yugoslavia, the three systems operated pump turbine (3SRPT) of the fourth unit of Moste hydro power plant,...
Fire Protection at the Grand Coulee Hydro Project
In the fall of 1980 a rupture of one of the Project's 525kV transmission cables occurred and created a fire. Power from three Third Powerplant 700MW units was interrupted,...
