Station Service Systems for Large Hydroelectric Generating Stations

Abstract: This paper is a review and comment on a number of factors to be evaluated in the design of a station service system. It deals particularly with auxiliary power schemes for large multi unit plants, and describes recent hydroelectric developments in Eastern Canada.

Northfield Mountain Pumped Storage Project

Abstract: The Northfield Mountain Pumped Storage Project will be a source of economical peaking power for the New England area, which continues to be an area of high transportation and fuel costs. In addition to the project’s capability to hydraulically store surplus power from conventional thermal and nuclear base load power sources, the 1,000,000 Kw facility will provide assured reserve (spinning reserve) capacity at extremely short notice. Emanating from this pumped storage project are accrual flexibilities in the form of multipurpose use which will provide optimum utilization of this project site. As well as providing a source of economic and instant power, the facilities encompass recreation and fish enhancement for public enjoyment. Further innovation utilizes the pumping and storage features to augment a major water supply system by diverting a portion of high freshet river flows which otherwise would be wasted.

Speed Regulation Study for Bay D’Espoir Hydroelectric Generating Station

Abstract: An island-wide power network has recently been built in Newfoundland, linking together the various local power systems for the first time. Power for this network will be provided from Bay d’Espoir powerhouse. Since most of the power stations already in operation are small and have slow governor times, it was important that the Bay d’Espoir units be able to respond quickly to major changes of load. A detailed study was therefore carried out using a computer to optimize the design parameters, the results obtained providing a detailed picture of the frequency changes resulting from various load changes on the system, and the corresponding water hammer and surge tank level fluctuations. A second study, now under way for the next stage of the project, shows the effect of increased load changes on the larger system.

Combustion in industrial gas turbines

Abstract: Publisher Summary This chapter discusses combustion in industrial gas turbines. Attempts have been made to operate industrial gas turbines on solid, liquid, and gaseous fuels of many different types, for application to the whole wide range of industrial and marine power production. The chapter discusses open, closed, semiclosed, and exhaust heated cycles. Long-life base load units have been derived by blending aero-techniques with steam turbine experience; short-life peak load units have been evolved by using aero-gas turbines as gas generators feeding power turbines. The fates of these many combinations of fuels, power plants, and applications have been determined by their technical feasibilities, practical operating characteristics, and overall running costs relative to the established prime movers. If the design of a single combustion chamber with a single atomizer and air register is attempted for an industrial unit of, say 4000 kW output, the resultant component may dominate the engine. In addition, to obtain an acceptable spray particle size would require a far higher fuel pressure than can be contemplated with confidence. Therefore, in large units, to obtain fine atomization, it is necessary to subdivide the fuel flow between a number of atomizers.
