Research on Current Adaption Control Strategy on Inverter of Ship

For the characteristics of heavy load and strong coupling of power system on ship, getting common positive and terrestrial active invert technologies together, current adaption control strategy on inverter is proposed in this paper for the research on the parallel technology of inverter and synchronous generator in hybrid energy system of ship. The control system model and method of determine key control parameters are gained by mathematical modeling and theoretical derivation. The research results indicate that the electrical system, parallel with inverter with proposed control strategy and synchronous generator, have advantages features of good steady and dynamic performance, higher power quality, high-efficiency of generator, and so on. This new type control strategy provides new research idea on new energy application on hybrid power supplies of ship, and have good application prospect on the application for inverter at new energy ship.
