摘　　要：针对船舶电力系统大负载、强耦合特点,结合陆上大电网并网逆变技术,提出逆变器电流随动控制策略,研究船舶多能源供电系统中逆变器与同步发电机并联供电技术。通过理论推导以及数学模型建立和仿真,获得控制策略实现及参数确定的方法。研究结果表明,所提出的逆变器控制策略与同步发电机并联构成的供电系统,具有稳定性高、动态特性好、供电质量优、发电机利用率高等优良性能,这种新型逆变器控制策略为新能源在船舶混合供电系统中的应用提供了新的研究思路,在船舶新能源逆变场合具有良好的应用前景。For the characteristics of heavy load and strong coupling of power system on ship, combined with the technology of grid-connected inverter on land, 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 the method of determining 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 of good stability, good dynamic performance, high power quality, high efficiency of generator and so on. This new 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 on new energy ship.
