The correction of voltage sag on mining machines utilising a locally connected STATCOM in the IDEA lab

In mining power systems, voltage sag caused by the starting currents of direct-on-line asynchronous machines can affect adjacent plant. This paper utilises a STATCOM installed on the terminals of an asynchronous machine, implementing a voltage support algorithm, to correct voltage sag. Experimental results are presented from a three phase, low voltage system showing the local correction of voltage sag. Further, this paper presents the first experiment conducted in the IDEA laboratory, an initiative between CRCMining and the Power Group at the University of Newcastle, Australia.
