永磁电机分布式发电PWM整流器的研究
摘要
由于传统的以集中式发电、超高压远距离输电为特征的电力系统的某些弊端,和传统能源资源的日益枯竭,分布式发电技术正越来越受到世界各国的重视,已经成为21世纪电力系统一个很重要的研究方向。
本课题以三相电压型PWM整流器在分布式发电系统中的应用为研究对象。根据永磁发电机的输出特性,首先对三相电压型PWM整流器的拓扑、工作原理进行了深入的分析,得出了其在不同坐标系下的一般数学模型,同时重点研究了电压矢量定向控制策略的电压、电流双闭环结构和PI控制参数设计。其次为了解决因永磁电机发电输出频率、幅值波动带来的锁相问题,将三相软件锁相技术引入到PWM变换器中,设计了三相软件锁相环的调节参数,并进行了模型仿真。然后结合空间矢量脉宽调制(SVPWM)原理,采用MATLAB7.3/Simulink6.5建立了PWM整流系统的仿真模型,通过对系统在实际工程应用中可能会出现的种种情况进行了模拟仿真,仿真结果验证了系统所采用的控制策略和锁相方法的可行性。最后以三菱公司的IPM和TI公司的TMS320F2812分别作为功率模块和控制核心,完成了整个系统的硬件和软件设计,进行了实验研究。

At the same time, the paper focus on the voltage -oriented vector control strategy with voltage and current dual-loop structure and the PI parameters design. Secondly, In order to solve the phase-lock issue, the paper introduced the Software Phase-Lccked Loop (SPLL) to the PWM converter. And based on the Space Vector Pulse Width Modulation (SVPWM) principle, the paper established a simulation model of PWM rectifier system using MATLAB7.3/Simulink6.5. It researched the simulations that may appear in actual engineering applications. The results verify that the system is feasible. Lastly, using TI’s TMS320F2812 chips as controllers, Mitsubishi company IPM module as a main circuit.It finished the three-phase voltage rectifier system hardware and software design.
