An electronically controlled drive for marine generators operated at constant rotational speed by the main engine of ships (RCF gearing installation)
Diesel engines which drive an electric generator operate with diesel oil and have a relatively high fuel consumption. Installations exist in which the generator is connected permanently with the crankshaft or propeller shaft. However their rotational speed varies because of the changing sailing conditions of the ship. Therefore the frequency of the alternating current produced by the generator is not constant either and thus requires resetting before retransmission to the ship's power supply. The thyristors used for this cause a very large loss of energy, which offsets the saving in fuel. The objective of this project was therefore the development of a transmission element which solves this problem mechanically: an electronically controlled drive for marine generators operated at constant rotational speed by the main engine of ships (hereinafter referred to as RCF). In the meantime a further step towards energy conservation was achieved in the development of diesel engines: the turbo compound system (TCS). Savings :- - without TCS, with RCF E' = 191 t/year, - with TCS, without RCF E" = 229 t/year, - with TCS and RCF E = 436 t/year.
