|
摘要
提出了一种并列结构混合励磁同步发电机,并对提出的交流励磁矢量控制策略进行了研究。首先,在混合励磁同步发电机的结构和工作原理的基础上,建立了数学模型,提出了一种利用电压空间矢量将交流励磁磁场定向于d轴的控制策略。然后,在MATLAB/Simulink环境下搭建了混合励磁发电机及励磁控制系统的仿真模型并进行了仿真研究。理论分析与仿真结果均表明,所提出的控制策略能够用最小的电励磁电动势得到最佳电压调整量,实现发电机输出电压稳定,并且输出电压的调节取决于励磁电压的q轴分量。仿真结果也表明该交流励磁控制系统具有良好的动态和稳态性能,负载变化时,发电机能够输出恒定的电压。
A coordinate structure hybrid excitation synchronous generator( HESG) was proposed and the AC excitation vector control strategy for HESG was investigated. Firstly,based on the structure and principle the mathematical model of HESG was established. One control strategy of AC excitation field oriented to the d-axis using voltage-space-vector was proposed. Then the model of HESG and its excitation control system were built and simulated with MATLAB / Simulink. The theory analysis and simulation results show that the proposed control strategy ensure that the system can achieve the optimal voltage adjustment with minimum excitation electromotive force and the output voltage adjustment only depends on the q-axis component of field voltage. And the simulation results also show that the system has good dynamic and steady-state performance,and the output voltage can keep constant when the load of HESG changes.
