摘　　要：采用PWM整流-逆变技术的新型船舶轴带发电系统是当今船舶行业的重点研究领域之一,而逆变器与柴油发电机组的长期稳定并联运行问题是该系统的关键问题之一,将柴油发电机组的有功功率-频率和无功功率-电压下垂特性引入到逆变器控制器可以解决该问题。介绍了新型船舶轴带发电系统的结构及运行原理,分析了基于引入的下垂特性的并联运行控制策略,基于Matlab/Simulink仿真软件建立了逆变器及其控制器、柴油发电机组以及系统仿真模型并进行了系统并联运行仿真。仿真结果表明控制策略是正确可行的。The novel shaft generating system using PWM rectifier and PWM inverter technology is one of the key research areas nowadays, and the long term parallel operation of the inverter and diesel generator set is one of the key problems of this system, the active power-frequency and reactive power-voltage droop characteristics of the diesel generator are introduced into the inverter controller to solve the problem. The system structure and operation principle of novel ship shaft generator system were proposed, the parallel operation control strategy based on the droop characteristics introduced was analyzed and the simulation models of the inverter with the controller, diesel generator set and the whole system were established based on the Matlab/Simulink software, with which the system parallel operation was simulated. The simulation results show that the control strategy is correct and feasible.
