Study on the Technology of MPLS in Wide Area Protection System
Subject to protection of power system, the article analyzes the communication technologies suitable for the current WAPS like IP exchange technology and MPLS etc. and analyzes the feasibility of these technologies in the field of power system WAPS. After comparative analysis of the current communication means, i.e. physical media and communication model etc., the article proposes a WAPS communication network scheme based on MPLS technology. Finally, the article uses network emulation software OPNET to simulate the communication performance of this communication scheme, compares it with current WAPS communication networks and gets the conclusion that the proposed wide area communication network scheme meets WAPS communication requirements
