摘要
本文首先对超级电容储能系统的基本工作原理以及充放电特性做了分析,之后利用能量约束法和功率约束法对超级电容储能系统进行了合理的设计,使其容量得以优化。最后由变流器VSC电路,双向DC-DC变换器及超级电容器组建立超级电容储能系统的主电路模型。其主电路中通过变流器VSC可以实现交直流的转换和功率恒定;而双向DC-DC变换器的一般工作过程,是在Buck(降压斩波器)和Boost(升压斩波器)两种模式下完成的。并在此基础上对主电路优化后的控制策略和参数进行设计。
This article analyzes the basic working principle and charging and discharging characteristics of the supercapacitor energy storage system,and then uses energy constraint method and power constraint method to design the supercapacitor energy storage system reasonably,so as to optimize its capacity.Finally,the main circuit model of the supercapacitor energy storage system will be established by the VSC circuit of the converter,bidirectional DC-DC converter,and supercapacitor bank.The main circuit of the bidirectional DC-DC converter can achieve AC/DC conversion and constant power through the VSC converter.The general working process of the bidirectional DC-DC converter is completed in two modes:Buck(buck chopper)and Boost(boost chopper),and based on this,the control strategy and parameters of the optimized main circuit are designed.
