飞轮储能的两种支承结构比较分析

Comparative Analysis of Two Supporting Structures for Flywheel Energy Storage

飞轮储能具有储能密度高、寿命长、不受充放电次数限制等特点,是目前最有发展前途的储能技术之一。分析了两种支承结构的飞轮系统形式,从理论分析上比较了两种不同的支承方式下飞轮系统的特点。结果表明,采用3自由度磁力轴承支承方式的飞轮系统具有良好的发展前景。

Flywheel energy storage system with the characteristics of high energy density, long service life and no restrictions on the number of charging and discharging is one of the energy storage technologies with best growth potential. The analysis on two supporting structures in the flywheel system has made a comparison of the characteristics given by the flywheel system under two different support pattern＇s from the viewpoint of theoretical analysis. The results show that the flywheel system supported by 3DOF magnetic bearing possesses sound potential for development.
