在地铁列车断路器动态特性检测中,引入飞轮储能系统能够有效回收列车再生制动能量,稳定断路器开关动作电压,但单飞轮储能系统容量较小,难以满足列车再生制动能量利用需求,飞轮储能阵列(FESA)是解决这一问题的有效手段.首先,分析飞轮储能系统的数学模型和运行特性;然后,考虑稳压节能及弱磁需求,给出基于多电压阈值的单飞轮储能系统控制策略,并在此基础上针对飞轮阵列均速控制和工作模式管理等核心问题,提出基于转差修正控制和基于"电压-转速-电流"三闭环控制的两种飞轮储能阵列控制策略;最后,通过仿真和实验验证飞轮储能阵列控制策略的可行性.
In the dynamic characteristic detection of subway train circuit breakers,the introduction of a flywheel energy storage system in the urban rail transit power supply system can effectively recover the regenerative braking energy of the train and stabilize the circuit breaker switch operating voltage.However,the single flywheel energy storage system has a small capacity,and it is difficult to meet the demand for train regenerative braking energy utilization.Flywheel energy storage array(FESA)is an effective means to solve this problem.This paper first analyzed analyzes the mathematical model and operating characteristics of the flywheel energy storage system.Then,considering the requirements for voltage stabilization,energy saving and field weakening,a control strategy for a single flywheel energy storage system based on multiple voltage thresholds was is given.Subsequently,aiming at the core issues of flywheel array speed-balance control and working mode management,two flywheel energy storage array control strategies based on speed-error regulation control and based on"voltage-speed-current"three closed-loop control were are proposed.Finally,the simulation and experiment verify that the proposed control strategy can be arrayed.the feasibility of flywheel energy storage array control strategy.
