摘 要

城市轨道交通作为大都市的首要交通体例，近些年来在海内的成长十分迅速。因为城轨站间间隔短，列车在频仍地起制动过程当中会发生大量的制动能量。因此，研究关于地铁再生制动能量的回收利用对于节约能源和可持续发展有着重大的意义和价值。

储能方式多种多样，各有其优势，但同样也有着其不足之处。这其中飞轮储能技术发展较其它储能技术较为成熟，因此成为再生制动能量回收利用研究的重点领域。

需要分别对飞轮储能系统的储能模式和释能模式两种工作模式下的飞轮电机设计相应的控制策略。分别采用前馈解耦的控制策略和逆系统方法对飞轮电机进行控制。

The study of Subway braking energy utilization based on Flywheel energy storage

Abstract

Urban Rail Transit as the Main Mode of Transportation in Metropolis. In recent years, the development of urban rail transit in our country is very prosperous. Due to the short distance between urban rail stations, the train will generate a large amount of braking energy during frequent braking. Therefore, study of regenerative braking energy utilization technology for urban rail transit has important significance and practical value on the energy-saving emission reduction and sustainable development.

There are various ways of energy storage, each with its own advantages, but it also has its own shortcomings. Flywheel energy storage system with rapid response speed, high power density, long life, and low pollution emissions, has become a key area for the study of regenerative braking energy recovery in subways.

The flywheel energy storage system has two working modes: energy storage mode and energy release mode, so it is necessary to design corresponding control strategies for the flywheel motors under these two working modes. Flywheel energy storage system adopts feed forward decoupling control strategy when working in energy storage mode. At the same time, the flywheel motor is controlled by the inverse system method to improve the control performance of the flywheel in the energy release mode.

Key Words: Regenerative braking；Flywheel energy storage；Control Strategy
