摘要
飞轮储能作为一种新型环保储能技术,在能源需求大幅提升的今天有着很广阔的运用前景。着眼于飞轮储能技术的一项难点——轴承支承系统,通过引入一种新型的无轴承悬浮技术,省去了传统支承系统的机械或电磁轴承,将飞轮转轴的悬浮与旋转驱动合二为一,并通过已成熟的多相电机技术及特有的控制策略加以实现。介绍了该新技术的基本原理、数学模型、控制策略及计算机仿真模型,并成功制作出符合要求的样机。
As a new type of environmentally friendly energy storage technology,flywheel energy storage technology has a wide application prospect because of the substantially increased energy demands.This article focuses on the bearing support system,which is a technical key point of the flywheel energy storage technology.A new type of non-bearing suspension technology is introduced,which eliminates the need for traditional mechanical or electromagnetic bearings,and combines the flywheel rotating drive with the suspending one.It has been achieved through traditional multi-phase motor technology and the unique control strategies.The article introduces the basic principles,mathematical models,control strategies and the computer simulation model of this new technology.A prototype has also been successfully produced to meet the requirements.
