Abstract :
This paper proposes a new technique in power line protection, the adaptive noncommunication protection. In this technique, protection relays make operate or restraint decisions, adapting to system and fault conditions, without the need for communication links. Operation without communication links to signal the remote end relay is achieved by the detection and identification of the operation of the circuit breaker at the remote end of the protected line section. An algorithm based on the symmetric components is proposed to detect and identify the balance condition of the system during the fault. The paper is focused on one of the three protection schemes based on the new technique, the delayed operation scheme. Simulation studies carried out for various systems and fault conditions have demonstrated the feasibility of the scheme.
