Abstract
Power swing and out of step power generation are essential issues in power system stability study and power system protection and security study. Power swing – either it’s stable or unstable- can effect protection relays coordination – specially distance relay – and lead to unwanted trip or unwanted loose of power to a critical consumer. Therefore, it is important to find a way to unable these relays to distinguish between power swing phenomena and an electrical fault. Also, we have to find a relay that can differentiate between a stable power swing and unstable one. This is the focal point of this report.
