Abstract: The phenomena of unexpected significant diminution of voltage on the connecting bars of the induction motors that drive industrial equipments determine their braking, the reduction of speed rotations without stopping them. When voltage recovers, induction motors begins to self-start. Do to the hard circumstances, not all of them can do it. That is why it is very important to know exactly the behaviour of each of induction motor of the group. The paper presents a method of computer analysis of the self-starting conditions providing professionals with a simple and efficient tool of evaluating the self-starting possibilities of induction motors sensitive to voltage drops and allowing them to find accurate technical solutions.

Brief Biography of the Speaker: Flavius Dan SURIANU was born in Timisoara, Romania on April, 2, 1949. He received the B.Sc. and the Ph.D. degrees in electric machines from the Politehnica University of Timisoara, in 1972 and 1987, respectively.
His academic career started in the autumn of 1977 at The Politehnica University of Timisoara where he is a professor in areas of Large Industrial Consumer Units, Identification and Mathematical Modeling of Power System Elements and Electromagnetic Compatibility. Since 2001 he is the head of the Power System Department. He has a remarkable scientific and didactic experience being the author of 16 books and of an E-book chapter, 89 papers published in national and international journals and conference proceedings and 67 research projects, mainly in the fields of transient and long term dynamics of power systems, mathematical models of large consumer units, high voltage and electromagnetic risk, electromagnetic compatibility, energy balances and renewable energies. He is a member of IEEE, CIGRE, AGIR (The General Association of the Engineers in Romania) and IRE - EURELECTRIC (The Romanian National Institute for Energy Development Studies).
