Abstract
Abstract
Power swing is a phenomenon that is basically caused by large disturbances in the power system. If not blocked, it can cause incorrect operation of distance protection and result in incorrect or unwanted disconnection of transmission line switches. Furthermore, if not prevented, it can lead to serious damage to the generator. This paper describes the basics of power system stability during power swings, lists the effects on the distance or other relay during power swing, and presents methods for detecting power swing, both traditional and advanced. Additionally, it provides a description of the settings of the Power Swing Blocking (PSB) scheme to meet these requirements.
