Background technology
Along with the development of power automation technology, electronic technology and computer network communication technology, electric power system has entered a high-speed development period, and electric power system is to intelligent, integrated future development.The construction of electric power system develops to horizontal and longitudinal both direction.Transversely, need between different operation systems to carry out data information sharing; In longitudinal direction, transformer substation system and scheduling back-up system, the superior and the subordinate dispatch between back-up system all to be needed to carry out sharing of data message.Presently, sharing of these data messages is mainly realized by electric power data network.Because the needs that electric power safety is produced, require electrical production transfer of data real-time, accurate and safety.But unavoidable generation communication failure in long range propagation process, as stuck in telecontrol communication machine process, communication link joint looseness, communications optical cable damages, communication equipment is subject to stronger electromagnetic interference etc., these faults cause transmission data not conform to the actual conditions, and then affect producers to the grasp of grid operating conditions and judgement.
The overall process of the through transfer of data of application of message, when transfer of data is interfered, will shows as message format and change, or message produces error code, causes electrical energy management system (EMS) to receive incorrect data.
Current disposition is, when a communication failure occurs, dispatching automation class, signal squad, three teams and groups of maintenance protection class carry out checking, processing in respective scope of offical duty, and three groups of personnel rush to the scene respectively and check respective equipment running status.According to statistics, in communication failure, Single Point of Faliure ratio is maximum, and troubleshooting mode so is not only delayed fault handling time, also causes the waste of human and material resources.
Summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of communication failure navigation system based on packet parsing.
The present invention is achieved through the following technical solutions:
