Research Of 104 Transmission Protocols For Network Access In Electric Power Dispatching System

The subject of network access in IEC 60870-5-104 transmission protocols for electric power dispatching system is researched in context.The thesis analysed the mechanism for this protocols and solved the problem of realization for 104 telecontrol module in CC-2000 dispatching automation system. The practical application is carried out in HPI real-time producting supervisal system.In sum, the main contents of this thesis include: The mechanism of IEC 60870-5-104 protocols is analysed carefully.The methods of realization 104 telecontrol module in CC-2000 dispatching automation system is put forward.The material scheme adopted in practical application for HPI real-time producting supervisal system is expounded.The design scheme and difficulties of software is analysed.The effect achieved in practical operation is validated.
