介绍了一个基于Matlab 2013a的10 kV中压交流大功率变频器两种方式实现失电跨越的设计与实现。首先概述了压气站压缩机对供电可靠性要求高,然后针对榆林首站详细叙述了遭遇“晃电”时压缩机、变频器、电源之间的能量交换过程,并设计双电源同期备自投装置,实现两路电源在一路失电情况下,在200 ms以内以同期方式快速投入另一路正常电源,实现双电源无缝切换。具有很强的实用性及推广性。 This paper introduces a design and implementation of two ways to achieve power loss across 10 kV medium voltage AC high power inverter based on Matlab 2013a. First of all, the compressors of compressor station are described to have high requirements on power supply reliability. Then the energy exchange process between compressors, frequency converters and power supplies is described in detail for Yulin first station. Since the device, to achieve two power loss in the case of all the way, within 200 ms in the same period quickly into the other normal power supply to achieve seamless dual power switch. Has a strong practicality and promotion.
