A Study of Transitional Modes of the Electric Network with the Powerful Electromechanical Load and FACTS

In this paper the flexible alternating current transmission system (FACTS) is proposed to minimize an influence of the direct start-up of a powerful induction motor (IM) that is a part of a node complex load (NCL) upon the modes of electric network (EN). Some results of model-calculation investigations of transients which appear in the EN during the direct start-up of four IMs, each having active power 8 MW are presented in the paper. These results confirm an effectiveness of the proposed FACTS.
