Abstract
A diesel generator set working at variable speed to save fuel is studied. The results of experimental studies of the operating modes of an autonomous diesel generator set are presented. Areas for regulating operating modes are determined. It is demonstrated that the transfer of the diesel generator set to variable speed of the diesel engine makes it possible to improve the energy efficiency of the autonomous generator source, as well as the environmental and ergonomic performance of the equipment as compared with general industrial analogues.
Highlights
All industrial diesel generator sets (DGSs) work at a constant speed with a wide range of changes in electric load
Experiments were conducted on the basis of a specific model of a diesel generator set, yet the theory of similarity of internal combustion engines and electrical machinery, as well as analogous results obtained by other researchers [10,11,12] make it possible to extend the conclusions to other DGSs with the same capacity range up to 100 kW
Specific fuel consumption for the production of 1 kWh of electrical energy is a key indicator of DGS energy efficiency
