ABB中压变频传动系统失电跨越功能的研究与应用

Study and Application of ABB MV Drive Ride Through Function

为了在电网瞬间跌落或闪变的工况下保持变频器不跳闸,ABB中压变频器提供强大的失电跨越功能,当电网的瞬间闪变或工作电源切备用电源瞬间,变频装置短时不停机。详细介绍了ABB中压变频传动的失电跨越功能;并在ABB开发的中压传动仿真平台上对失电跨越功能进行仿真研究;最后在兰州石化天然气压缩机变频改造项目中成功应用;在理论分析、仿真研究和现场测试的基础上得出相应结论。

In order to keep the drive does not trip when the grid voltage sag or fluctuate,ABB MV drive provide powerful ride through function. When the grid voltage instantaneous fluctuates, the MV drive can continue run for short time without trip. The ABB MV drive ride through function was described, simulates study this function at the platform developed by ABB and tests this function at ABB factory test stand, finally successfully apply in one compressor retrofit project of the Sino Petrol Lanzhou. Corresponding conclusion can be made from theoretical analysis, simulation studies and field tests.
