摘要
对船舶轴带双馈发电机的数学模型和控制方式进行了详细探讨,研究了船舶轴带双馈发电机的空载并网控制和功率解耦控制两种控制策略,并在Matlab/Simulink环境下,搭建了两种控制模式下的双馈发电仿真系统,对轴带双馈发电系统的相关动态和静态特性进行了仿真和分析。结果表明:轴带双馈发电机在空载并网控制模式下具有良好的跟随参考电压特性,在功率解耦控制模式下具有良好的功率解耦特性,对有功功率和无功功率给定能够快速响应,稳态误差被控制在较小范围内。
The mathematical model and control method of doubly fed shaft generator for ship are amply discussed. The two control strategies of free-load grid-connecting and power decoupling are researched. The simulation system of the doubly fed shqfi generator at two control modes is established under Matlab/Simulink environment. The characteristics of relevant dynam＆ state and static＂ state with the doubly fed shqft generator are simulated and analyzed The results demonstrate that the doubly.fed shaft generator has good performance on tracking the reference voltage under the mode of free-load grid-connection, and has good performance on power decoupling under the mode of power decoupling. It responds to active power and reactiw） power quickly and the steady-state error is controlled in a small range.
