摘要
为保证风机的24 h不间断供电,提高电能质量,满足国家节能降耗和大储能的要求,提出了一种新型的井下局部通风机的储能型变流器装置,既能实现电网正常运行时的无功补偿和削峰填谷的作用,又能在系统停电时,作为应急电源使用。通过对该装置的基本工作原理进行介绍,探讨了储能系统稳态运行时的最佳控制方法,并结合煤矿的特殊性,对实际设备容量进行设计。
In order to ensure the local fan can work uninterruptly work everyday, improve power quality and meet the requirement of national energy saving and large energy storage, presents a new type of energy storage converter for underground fan, which can not only realizes the reactive power compensation and peak load shifting during normal operation of power network, but also be used as emergency supply when the power network is breakdown. By introducing the basic working principle of this device, chooses the optimal control method during the state of steady operation and designs the actual capacity of the equipment combining with the particularity of coal mine.
