模块化高功率密度储能变流器的研究

Research on Modular High Power Density Energy Storage Converter

针对传统储能变流器升级困难、不易维护等缺点,研究了基于模块化设计理念的储能变流器,阐述了高功率密度的结构设计方法,为降低装置空间体积奠定了基础;研究了DC/DC与DC/AC各自独立的并联控制方法,为模块化储能变流器的扩容运行提供了技术支撑;研制了储能直流变流器与储能交流变流器,并针对并联控制方法进行了试验验证。

Aiming at the shortcomings of traditional energy storage converter,such as difficult upgrade and maintenance,the energy storage converter based on modular design concept is studied,and the structural design method of high power density is expounded,which lays a foundation for reducing the space volume of the device.The independent parallel control methods of DC/DC and DC/AC are studied,which provide technical support for the expansion operation of modular energy storage converter.Energy storage DC converter and energy storage AC converter are developed,and the parallel control method is tested and verified.
