SYSTEMS AND METHODS FOR POWER SWING AND OUT-OF-STEP DETECTION USING TIME STAMPED DATA

摘要

A first intelligent electric device (IED) may be placed at a first location inan electrical power system and a secondIED may be placed at a second location in the electrical power system. Voltagemeasurements may be received from the first andsecond IEDs. The measurements may be time aligned and used to calculate anangle difference between the first location and thesecond location in the electrical power system. A slip frequency andacceleration may be derived from the angle difference. Theangle difference, slip frequency, and acceleration may be used to detect anout-of- step (OOS) condition in the electrical powersystem and/or a power swing between the first location and the second locationin the electrical power system. The angle difference,slip frequency, and acceleration may also be used to predicatively detect OOSconditions.
