船舶轴带无刷双馈独立发电系统的综合控制策略设计与仿真

为了提高船舶轴带无刷双馈独立发电系统的控制精度和鲁棒性,采用综合控制策略对传统基于功率绕组磁场定向的控制策略进行改进。综合控制策略不需要估算转子电流,减少了对电机参数的依赖,因此具有更强的鲁棒性。在Simulink中对综合控制策略在负载突变和转速突变工况下的控制效果进行仿真验证,结果表明综合控制策略相比传统基于功率绕组磁场定向的控制策略具有更好的控制精度和鲁棒性,更适用于船舶轴带无刷双馈独立发电系统。

Design and Simulation of a New Integrated Control Strategy for Ship Shaft Brushless Doubly-Fed Machine Stand-Alone Power Generation

In order to improve the accuracy and robustness of the control strategy of stand-Alone power generation system for marine shaft Brushless Double-Fed Machine, the comprehensive control strategy which including the control winding-side converter that based on the control current vector decoupling control and the power winding side converter that based on the power winding voltage orientation is proposed. The comprehensive control strategy does not need to estimate the rotor current and does not depend on the motor parameters. Therefore, it hasbetter robustness. Simulation results show that the proposed comprehensive control strategy is more robust and controllable than the traditional control strategy based on the magnetic field orientation of power windings in the Simulink environment under load abrupt and sudden speed change conditions, so it is more applicable to the stand-alone power generation system for marine shaft Brushless Double-Fed Machine.
