中文摘要:
      三相并网逆变器是分布式电源接入电网的重要接口,其控制性能直接影响电能的质量。应用现代控制理论的状态空间法建立了三相SPWM逆变器电路的状态空间模型,对系统能控性、能观性、稳定性进行了定性分析,采用MATLAB/Simulink软件建立了三相逆变器电路的仿真模型,并输出结果。仿真结果表明了应用状态空间法对三相并网逆变器电路进行建模分析的正确性,为进一步研究分布式电源并网特性从而获得更好的电能质量和电网稳定性提供了很好的方法。
英文摘要:
      The three-phase grid-connected inverter is an important interface between the distributed power source and the grid, and its control performance directly influences the quality of electric energy. In this paper, a state space model of the three-phase SPWM inverter circuit is established in the state space method applying modern control theory, and the controllability, observability and stability of the system is analyzed qualitatively. Furthermore, a simulation model of the three-phase inverter circuit is established by use of MATLAB/Simulink software, and output results are obtained. The simulation results show the correctness of the modeling and analysis of the three-phase grid-connected inverter circuit through use of the state space method, thus providing a good means for further study on distributed power supply to obtain better electric power energy and grid stability.
