Design And Implementation Of IEC61850 Standard Server Program

IEC61850 is an international standard about substation automation system structure and data communication, the same world, the same standard, the impact of the industry and the market is revolutionary and long-term. The application of uniform standards for power system users and power equipment suppliers, and system integrators are also favorable. But agreement IEC61850 system is very large, to implementation of IEC61850 based on the whole system needs to solve many technical problems, plus international has many communication standard is introduced into the domestic power system, these standards are not uniform, such interoperability problems has also been substation automation system in the face of problems. At present, many existing substation systems still adopt the traditional protocol system, which brings some difficulties to the popularization of IEC61850..This thesis is aiming at the above problems, according to IEC 61850 protocol system as the object of study, in depth analysis of the protocol defined in the abstract communication service interface, logic node modeling, service layer mapping technology, consider how some achieved through traditional communication protocol system of substation system access to IEC61850 system, analysis of traditional communication protocol and conversion to IEC61850 protocol model were detailed research and analysis. The main content is:1. The research of IEC61850 Abstract communication service interface(ACSI, design ACSI basic data model, data model mainly expressed protocol defined in the service, logical device, logical node, the logic relation between data and attribute data, through design ACSI interface function and interface functions to achieve, logical device, logical node communication.2. To study the MMS service interface and BER encoding and decoding logic, MMS is application layer protocol, the design of MMS service interface for processing IEC61850 through the network transmission data, the BER encoding / decoding is also the MMS protocol defined content, IEC61850 protocol provides communication must be by BER coding decoding method for transmission of data encoding and decoding.3. study the ACSI service interface and MMS service interface mapping and front design ACSI service interface and MMS service interface is actually one-to-one, design a service interface mapping is ACSI data model of IEC61850 server or client data object or attribute data conversion for the data object and attribute of the MMS protocol is defined.4. The research of traditional communication protocol analysis. At the same time, the analytical data is converted to IEC61850 defines the ACSI data model, this part of the design as an independent program modules, easy to network engineering, paper will be the module definition for communication processor module.5. The SCL(substation configuration data file read to achieve, network engineering and communication data are through the configuration description, part of the contents of this design is mainly from the existing engineering configuration will be data read data model in IEC61850, used for the transmission of the communication.6. The research of IEC61850 server and client communication logic, logic design is mainly server data model is mapped to the client to display, and then through the model data access, real-time updates of data communication.
