Hydrogen energy sources with current inverters in ship AC power plants

Abstract

The use of hydrogen energy sources is promising for the creation of ship electric-power systems. These sources have a number of significant advantages over conventional energy sources (diesel generators or turbine generators), such as the possibility to provide low-noise regimes of ship motion and creation of an airindependent shipboard power plant. Using hydrogen energy sources as components of electric-power systems along with conventional energy sources makes it possible to optimize the operation of diesel generators as regards minimum fuel consumption and provide a reserve of power. The article analyzes the structural variants of energy channels with hydrogen energy sources and current inverters providing parallel operation with diesel generators or turbine generators in ship ac electric-power plants. The problems of regulation and distribution of active and reactive powers between sources operating under a total load are considered. Comparative analysis of the generalized energy indicators and of the degree of distorting influence of energy channels with hydrogen energy sources on the voltage waveform of a ship electrical-power network in static operating modes is presented.
