摘要
首先分析了飞轮储能系统中双向能量变流器的基本原理,然后提出了飞轮储能系统的充放电优化控制策略,包括充电时的改进复合控制策略和放电时的综合优化弱磁控制策略,解决了应用传统控制策略所面临的局限性,并给出系统控制框图。进行了仿真研究和实验验证,结果表明,所提出的充电控制策略适合飞轮工作模式,恒转矩控制至恒功率控制切换迅速;所提出的放电控制策略能在全功率范围内稳定直流母线电压,是有效的和可行的。
The principle of bi-directional converter of the flywheel energy storage system （FESS） is discussed in this paper. Then the optimization control strategies of charging and discharging for FESS is presented, including improved multiple control strategy for charging and integrated optimization flux-weak control strategy for discharging which is used to solve the limits of the traditional control strategies. Then the system control scheme is given. Simulation and experiment analysis are executed. The results show that the proposed charging strategy fits well with the working pattern of flywheel, and switching from constant torque control to constant power control is quick enough; the discharging strategy can stabilize the DC-link voltage under any possible output power, so both strategies are effective and practical.
