船舶电力系统中发电机控制负载有效性研究

Development of permanent magnet generator directly coupled marine propulsion system

船舶结构不断发展,其复杂性也越来越高,其中包括负载的复杂性。负载运行的电流、电压及功率都会对发电机产生一定的影响。本文通过研究电子负载的特性,选用双PWM变换器更为合理,通过控制电子元件的占空比大小,对实际负载进行模拟,建立PWM的数学模型,最后通过仿真平台对PWM变换器进行仿真验证,得出发电机对负载控制的有效性。

With the development of the ship's structure,its complexity is getting higher and higher,including the complexity of the load. Load running current,voltage and power will have some impact on the generator. By studying the electronic characteristics of the load,the choice of dual PWM converter is more reasonable,by controlling the duty ratio of the size of electronic components,the actual load simulation,the mathematical model of PWM,and finally through the simulation platform PWM converter was simulation verification,the validity of the generator load control.
