Embodiment Construction
[0040] The present invention will be further described below in conjunction with accompanying drawing.
[0041] The invention discloses a self-synchronizing longitudinal current differential protection method suitable for transmission lines, which includes the following steps:
[0042] A self-synchronizing current differential protection method suitable for transmission lines, comprising the following steps:
[0043] (1) The relay protection devices at both ends of the protected line collect in real time and obtain the ABC three-phase current sampling sequence; the two ends of the protected line are independently sampled, and the sampling process is not required to be strictly synchronized (the time scale density can be reduced), but it should be used. A high sampling frequency is used to ensure the accuracy of the time of failure and the accuracy of data synchronization. It is recommended that the sampling frequency is not lower than 3200 Hz, and the sampling frequency used i...
