摘要
储能技术是目前构建新能源产业格局的关键技术之一。首先,总结了传统储能系统的技术特点和不足,提出了一种新型飞轮组储能系统(FESS),并分析了其结构特点和工作模式;然后,建立了飞轮组储能系统的理论分析模型;最后,以地铁列车再生能量回收为案例,采用试验和MATLAB仿真分析,将其和传统的蓄电池组储能、电容器组储能系统进行了比较。研究结果表明:飞轮组储能系统在储能密度和峰值功率输入输出﹑充放电稳定性、响应时间﹑供电网波动等技术指标上较传统储能系统均有较大提升,且列车停车时耗电量减少,启动时牵引波动率明显下降。
Energy storage technology is currently one of the key supporting technologies for establishing a new energy industry pattern.The technical characteristcis and shortcomings of the traditional battery energy storages were summarized,thus a new energy storage device of flywheel energy storage system(FESS)was proposed,and its structure and work modes were explored.Secondly,the theoretical mode of FESS was established.Finally,taking the regenerative energy recovery of subway trains as an example,the experiment and MATLAB simulation analysis were carried out to compare the FESS with the traditional energy storage system of battery bank and capacitor bank.The results show that,the storage density,peak power input and output,charge and discharge stability,response time,power supply network fluctuation and other technical indicators of the FESS are greatly improved compared with the traditional energy storage systems,and the power consumption is reduced when the train is stopped,and the traction fluctuation rate is significantly reduced when the train is started.
