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

The Impact

Based on the topology of wide area protection system (WAPS), after studying the reliability of hardware system and information flow in the WAPS and establishing the reliability assessment model, the multi-service reliability analysis method with multi monitoring and protection tasks in WAPS was proposed. In the model, the impact of network quality of service (QoS) such as information flow loss and delay, is studied. On the base of the model, the multi-service reliability evaluation method is employed to analyze the reliability of a WAPS of IEEE14 node power system, and the key nodes of the WAPS is given, which provides a basis for improving the reliability of the WAPS.
