摘要
该文介绍了一个矿井布置两部4800kW大功率矿井提升机,应用DTC电气传动技术,实现消除谐波、功率因数恒为1的目的,同时加速运行母线电压降小于4%。
This paper introduces that two 4800kW hoist were towered in same power supply,how to use the DTC driver to conform the standard of power,how to get rid of harmonious voltage and harmonious current,how to keep the power factor always 1,and how to keep the voltage drop under 4% when they are working at the same time.
