摘要

数字式雷达属于一种典型的脉冲负载,其具体特点表现为周期性的功率突增突减。光伏设备中的蓄电池由于充放电速率较慢,对于脉冲负载频繁的功率突变往往无法快速响应;而超级电容凭借其比功率大、充放电速度快的特点可以对尖峰功率做出快速补偿。基于此,文中提出利用混合储能的方法来解决脉冲负载供电中存在的问题。在Matlab/Simulink软件中搭建脉冲负载和光储系统的仿真模型,对比分析了蓄电池对脉冲负载单独储能和混合储能时系统运行参数。仿真结果表明:混合储能方案能有效且稳定地供电。
        Digital radar is a typical pulse load. The specific performance of pulse load is periodic sudden increase and anticlimax in power. The battery in photovoltaic power generation is unable to respond to frequent mutations in the load quickly,due to its slower charge-discharge rate. The super capacitor can make quick compensation for peak power by virtue of its high specific power and fast charging and discharging speed. Thus,a method of hybrid energy storage is proposed to solve the problems in the pulse load power supply. The mutation load causes a series of power quality problems. The simulation model of pulse load and photovoltaic energy system have been built in Matlab/Simulink. The performance comparison of battery separate energy storage and hybrid energy storage are compared and analyzed. It is shown that the hybrid energy storage scheme can provide effective and stable power supply to the pulse load.
