Application of AC-AC Frequencyconversion Technology Based on SIMADYN-D Controller in Mine Hoist

Abstract

In order to solve the problem of capacity expanding of electric control system of mine hoist, an application scheme of AC-AC frequency-conversion with vector control based on SIMADYN-D controller and homemade power cabinet was proposed and the interface problem between SIMADYN-D controller and homemade power cabinet was analyzed. The actual application showed that applying the scheme can save cost of AC-AC frequency-conversion system, decrease energy dispassion and expand capacity of mine hoist.
