Abstract

Steam turbine driven generating power plants have been of the main strength in electric power nets on land in these 30 years. However, the situation or condition is now changing, owing to circumstances of“Oil”.
In this paper, an establishment or a development of large electric generating power plants, founded on a new idea, which can be used not only in electric power nets on land but also in electric power plant barges and so on is proposed, in order to solve an electric power energy problem which is most important at present in the world economical problems.
The above electric power plants are based on the idea in which a plurality of diesel engines is combined with each other by a speed-up gearing in order to drive a large output power generator.
The feasibility of the above new power plants is largely dependent upon techniques which have been developed in fields of ship propulsion systems.
The special features of the above plants of the idea compared with steam turbine electric power plants having the same capacities are as follows:
(1) Costs of construction or building of the new plants are cheaper.
(2) Heat efficiencies of the new plants are higher.
(3) Practical differences of efficiencies between the said two plants become further larger, owing to features that the above new plants can easily be stopped through the night, and there are differences of efficiencies in partial load operation of the said two plants.
