What is Power Swings in Power System Protection about?
Power swings in power systems occur due to oscillations between generators and can lead to distance relays entering tripping zones, necessitating the ability to distinguish between faults and swings. The behavior of the system during these swings is analyzed using swing impedance charts, which illustrate the relationship between the impedance seen by the relay and the conditions of the generators. To prevent unwanted tripping during power swings, relays can be designed to only respond to fault conditions by
