Buck模式超级电容储能系统优化设计
|
摘要
为进一步提高超级电容储能系统充电响应速率,提出电流电压双环补偿控制策略。建立脉宽调制(PWM)整流器触发网络、电压电流反馈网络以及Buck变换器的数学模型,给定系统参考值,形成双闭环网络控制;采用复频域特性分析方法进行系统参数补偿,搭建仿真和实验平台。结果表明,通过对超级电容储能系统的双闭环控制及电路补偿网络优化设计,系统的充电速度可提高25%。
In order to further improve the charging rate of ultracapacitor energy storage system,a current voltage double loop compensation control strategy is proposed.The trigger network of the pulse width modulation(PWM) rectifier,the voltage and current feedback network and the mathematical model of the Buck converter are set up.The reference value of the system is given, and the double closed loop network control is formed.The complex frequency domain characteristic analysis method is used to compensate the system parameters, and a simulation and experimental platform are built.The results show that the charging speed of the supercapacitor energy storage system is increased by 25% through the double closed loop control and the circuit compensation network optimization design.
