Electrical power distribution system, method for powering a corresponding task, propulsion system and method for a ship

A method of supply a charge via a system for distributing electrical energy, comprising:

• driving, by a heat engine, an assembly of electrical energy generators that supply a distribution network;
• recovering the heat energy generated during the operation of the heat engines and for vaporizing a working fluid;
• driving, by the working fluid, a steam turbine associated with a generator connected to the distribution network for converting the recovered heat energy into electrical energy and at least one frequency converter arranged between the distribution network and an electrical load;
• regulating the flow rate of the vaporized working fluid at maximum steam;
• and
• controlling the frequency of the distribution network.

Propulsion system for a ship, comprising:

• a principal heat engine driving a line shafting;
• an auxiliary electrical motor coupled to the line shafting and supplied by an electrical power distribution network, said distribution network being supplied by auxiliary heat engines associated with electrical energy generators;
• a heat exchanger configured for recovering the heat energy generated during the operation of the propulsion system and for vaporizing a working fluid;
• a steam turbine driven by the working fluid and associated with a generator connected to the distribution network for converting the recovered heat energy into electrical energy, and
• at least one frequency converter arranged between the distribution network and the auxiliary electrical motor,
• a controller configured for controlling the frequency of the distribution network, where the flow rate of the vaporized working fluid is regulated to a maximum value.
