  • Method and a system for a fast bus transfer in an electrical power system
    Patent number: 9923375
    Abstract: A method for synchronizing and connecting a first sub power system with a second sub power system with an intelligent electronic device (IED) by use of at least one switching device between the first sub power system and the second sub power system in an electrical power system is provided. The IED monitors power supply parameters such as voltage magnitude, phase and other derived parameters such as voltage and phase differences in the first sub power system and the second sub power system to identify at least one instance for fast bus transfer where the two sub systems have acceptable differences in magnitude and phase. The IED performs phase shifting and voltage magnitude correction in anticipation for synchronizing power supplies on connection at the identified instance.
