Switching control between variable frequency and power frequency of emulsion pump in coal mine
In view of problem of high impulse current when scheme of multiple pumps linkage with one frequency converter applied in coal mine emulsion pump station, asynchronous switching and synchronous switching control scheme between variable frequency and power frequency of emulsion pump were proposed. The...
