In recent years, smart grid construction led the development of high voltage, wind and other clean energy, energy storage technologies, the main energy storage including methods such as: batteries, superconducting, the flywheel, super capacitors and hybrid energy storage system. How to use the proper energy storage device to absorption and utilization of regenerative braking is a hot topic of energy. Flywheel energy storage system combines many advantages, developing very rapidly. Therefore, this paper proposed absorption of regenerative braking energy using flywheel energy storage system to improve the utilization of regenerative braking energy, and increase the reliability and stability of traction power supply system.This paper will establish urban rail transit power supply simulation system to analysis of regenerative braking energy, and then base on the simulation software-PSCAD/EMTDC, using Nanjing Metro Line fundamental for the basis simulation data. Quantitative analysis of the rail transit regenerative braking energy feature, to reveal how the remaining regenerative braking energy impacting of the urban transit system, and to reveal the operate characteristics of the braking resistor.This paper puts forward a method using flywheel energy storage system that is based on Permanent Magnet Synchronous Generator (PMSG) to regulate the regenerative braking energy. It is composed of electric motor and VSC PWM. This paper will research the principle of the Permanent Magnet Synchronous Generator (PMSG), and its modeling, control and simulation. This paper will use outer voltage loop control and inner current loop control, and joined traction energy storage logic relationship between train started and braked. Through the time-domain simulation of the flywheel energy storage in the traction power supply system to analysis its operation feature. The simulation results verify the feasibility of the flywheel energy storage system model and the control strategy.
