EIGEN-PROPERTIES BASED COHERENT MACHINE IDENTIFICATION AND STABILITY ENHANCEMENT USING WIDE AREA PSS IN MULTI MACHINE POWER SYSTEM
Abstract

Author(s): Sanjeev Kumar Kushwaha, Prof. Alka Thakur

This paper describes coherent areas and their tolerances in the inter-connected power system networks, non-generating buses are assigned to each group of coherent generator using similar coherency de tection techniques. The method is evaluated with four test systems and coherent generators and areas are obtained for different operating points to render a more accurate grouping approach which is valid across a wide range of naturalistic operating points of the system. Index Terms—Inter Area Oscillations, Coherency, Transient Stability, Eigen value analysis.
