Study of various parameters in diesel-generator sets

Abstract

A diesel generator is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. Diesel generating sets are used in places without connection to the powe grid, as emergency power-supply if the grid fails, as well as for more complex applications such as peak-lopping, grid support and export to the power grid.Setsizes range from 8 to 30 kW (also 8 to 30 kVA single phase) for homes, small shops & offices with the larger industrial generators from 8 kW (11 kVA) up to 2,000 kW (2,500 kVA three phase) used for large office complexes, factories.In addition to this there are factors which diesel generators depend on they are Ambient Temperature , Load on the Generator ,Altitude of operation of the generator.Ambient generator refers to the Inlet temperature .Because the generator works with the diesel engine, the heat that the diesel engine emit make ambient temperature more than 40 celcius. However temperature should be less than 40 celsius for operation. In the present work behaviour of 62.5 KVA Diesel-Generator is studied in ANSYS V13.0 (A licensed Institute software.) First a schematic approximation of the diesel-generator is drawn in the ANSYS Software and then the Experiments are mae to determine the temperature conditions of various surfaces under constant load.These observations are taken for the simulation in the software and the results are displayed.
