摘要
基于容量约束配置方法配置的超级电容阵列吸收功率远小于城市轨道交通车辆电制动功率,造成制动能量的浪费。由于超级电容阵列的充电初始电压值对其合理配置影响很大,存在理论上的最优值,因此在分析车辆再生制动电气特性基础上,建立超级电容阵列功率和容量需求数学模型,提出满足制动能量回收电气参数的功率-容量约束配置方法,然后从最低工作电压的角度对该方法中的充电初始电压进行优化,并给出超级电容阵列的优化配置流程。算例分析和仿真验证表明:基于功率-容量约束配置方法配置的超级电容阵列能够满足城轨车辆制动能量回收的需求,节能效果优于容量约束配置方法,且具有较高的节能/质量比。
Using super-capacitor bank with the capacitor constrained configuration method will cause braking energy to be wasted,because the absorbing power of super-capacitor bank is far less than the vehicle braking power of urban rail transit.The charging initial voltage of super-capacitor bank has a decisive effect on its reasonable configuration and has an optimal value theoretically.Therefore,based on analyzing the electrical characteristics of vehicle regenerative braking,a mathematical model of super-capacitor bank is developed taking into account power and capacitor constraints,and a power and capacitor constraints configuration method is proposed to meet the requirements of electrical parameters for braking energy recovery.Then a super-capacitor bank optimized configuration procedure is built from the view of the minimum operating voltage to optimize the charging initial voltage of the proposed method.The results of the case study and simulation has proved that the super-capacitor bank with the power and capacitor constrained configuration method can meet the requirements for the energy recovery of urban rail transit vehicle＇s electrical baking,has better energy-saving performance compared with capacity constrained configuration method,and has a higher energy saving/mass ratio.
