  • Power generation cassette type power plant for marine electric propulsion and a controller thereof
    Patent number: 4808835
    Abstract: A power generation cassette type power plant for marine electric propulsion includes a multiplicity of power generation units each being formed as a power generation cassette including a power generator, a prime mover, for example an internal combustion engine for driving the power generator and a support structure for supporting the power generator and the engine internally. The support structure is formed in the same shape as that of a container for transporting cargo. When the power generators of the multiplicity of power generation units are operated in parallel to each other to supply electric power to a load, controllers serve to share the load to the generators properly.
