Title: Wide area measurement based protection support during power swing

Abstract: Oscillation in power system occurs following fault, tripping of generator or load change. Such oscillation causes relay maloperation which may further lead to cascade tripping. This paper proposes a method to prevent maloperation of relays during power swing condition using wide area measurements system (WAMS). Features derived from WAMS data are used for assessing power swing condition to help network protection decision. It classifies a power swing according to its severity and its effect on the operation of relays in the system. Integration of information obtained from the features using fuzzy logic based algorithm is applied to derive the decision. Relaying strategy in the system can be adjusted depending on the state of the area (safe, alert, high-alert and unstable). The performance of the algorithm is tested on an Indian power system. © 2014 Elsevier Ltd. All rights reserved.
