针对飞艇大功率设备起动时低压直流电网压降问题,对基于超级电容储能装置的供电系统进行研究。利用超级电容储能装置大电流放电特性,完成大功率用电设备启动,平衡母线电压。使用matlab/simulink建立电源系统模型和储能装置模型并进行仿真验证,结果表明该方法提高了低压直流供电系统瞬时大电流放电的能力,保证系统的运行稳定性。
Aiming at the problem of voltage drop of low voltage direct current (DC) power grid when airship high power equipment is started, the power supply system based on super capacitor storage device is studied. Use of super-capacitor storage device high-current discharge characteristics, complete high-power electrical equipment to start, balance the bus voltage. The power system model and energy storage device model are established by matlab / simulink and verified by simulation. The results show that this method improves the instantaneous high current discharge capability of low voltage DC power supply system and ensures the system stability.
