基于光储直流微网逆变器的研究

Research of optical storage DC micro-grid inverter

随着微电网的应用越来越广泛,其主体设备并网变流器的研究已成为核心关注点.针对微网的特点,本文设计了一种基于三点比较跟踪法和SVPWM技术的三相微网逆变器.分析了逆变器工作原理和结构,并就微网逆变器MPPT算法和SVPWM的实现进行详细设计.在此基础上,建立了基于SVPWM的微电网逆变器模型,仿真并搭建实验平台验证所采用的MPPT和SVPWM方法的有效性.仿真和实验结果表明,相比传统的逆变器控制方法,本文的方法能够更好地实现微网电能的传输效果.

With the application of micro grid is more and more widely,the inverter as the main equipment has bec ome the core focus in the grid research.Aiming at the characteristics of the micro grid designs a three phase inv erter based on the three point comparative tracking method and SVPWM technology.The paper analyzes the wor king principle and structure of the inverter and major designs micro grid inverter MPPT algorithm and SVPWM.B ased on above,paper builds micro inverter model,and establishes simulation model and experimental platform to validate the effectiveness of the MPPT and SVPWM method.The results show that the control method can better achieve transmission effect of micro grid power.
