摘要

为了提高常规轴带发电系统总体性能，本文研究了一种采用PWM逆变技术的新型船用轴带发电系统。通过采用虚拟发电机控制技术，使逆变器输出具有与柴油发电机组相似的电压．无功功率和频率．有功功率下垂特性。利用MATLAB／Simulink搭建了新型轴带发电机组的仿真模型，对控制策略进行了验证，为该系统应用于船舶的正确性和有效性提供了技术支撑。%In order to increase overall performance of the shaft generator system, a new type marine shaft generator system with PWM inverter is discussed in the paper The virtual synchronous generator control algorithm is adopted to achieve the frequency-active power and voltage-reactive power droop characteristics, which are similar with the diesel generator system. The simulation model of the new shaft generator system is built in MATLAB/Simulink, and the control algorithm is verified to support its correctness and effectiveness used on the ships.
