METHOD FOR AUTOMATIC REGULATION OF VOLTAGE FREQUENCY, PROGRAMMING AND DISTRIBUTION OF ACTIVE LOAD BETWEEN DIFFERENT TYPES OF POWER SOURCES OF VESSEL Russian patent published in 2021 - IPC F02D29/06 

FIELD: electrical engineering.

SUBSTANCE: method is proposed for automatic regulation of the voltage frequency, programming and distribution of the active load between different types of power sources of a vessel. The invention can be used on ship-based automated power plants. The essence of the invention consists in equipping main engine (1) and auxiliary diesel generators (4.1, 4.2) with turbocompound systems containing booster electric machines (8, 14.1, 14.2); using booster electric machines (8, 14.1, 14.2) in the mode of electric engines at partial loads and in the mode of recycling gas turbine generators at normal loads of their diesels for adaptive regulation of air supply; parallel operation of autonomous diesel generators (4.1, 4.2), shaft generator (29), recycling gas turbine generators (8, 14.1, 14.2) and secondary resource source (40); forced load distribution between generators according to a criterion of the highest economic and environmental efficiency due to parallel operation unit (70); related regulation of the voltage frequency of a power grid by comparator (79) of actual and set frequency via electric consoles (28) of shaft generator and (26.1, 26.2) diesel generators.

EFFECT: introducing a criterion of the highest economic and environmental efficiency in the management of the parallel operation of different types of power sources, expanding the scope of application of the method on any composition of generator sets, removing the restriction from the load mode of diesel generators below 30% of the nominal one, simplifying management means.
