Ride-through solutions: Classification and comparison

In this paper, ride-through solutions for induction electric motors classified by the parameters of a voltage tolerance curve. Methods for comparison of such solutions offered under a uniform and others distribution of voltage sag parameters. For an uniform distribution of sag parameters we suggest to choose variant with minimal division ride-through solution cost and reduction trip area, for others distribution choose variant with minimal division ride-through solution cost and reduction trip volume. The proposed methods allow make decision on choice ride-through solution for industry bus taking into account voltage sag parameters distribution, including oil wells with ESP.
