Data interaction method and data interaction system for scheduling master station and transformer substation based on MMS (Multimedia Messaging Service)

Abstract

The invention discloses a data interaction method and a data interaction system for a scheduling master station and a transformer substation based on MMS (Multimedia Messaging Service). The data interaction method comprises the following steps: expanding a communication model based on MMS, obtaining a system description model of the transformer substation, confecting an agency service interface to the transformer substation; setting up the corresponding relation between a resource mark number of the scheduling master station and the resource access path of the transformer substation according to the agency service interface and the system description model of the scheduling master station, performing data interaction with the transformer substation. According to the data interaction method and the data interaction system, the communication is performed in an object-oriented way, thereby solving the problems in the traditional technology that necessary protocol conversion and message point table maintain are needed, and all information types in the intelligent transformer substations cannot be covered. Furthermore, the work load of manual maintaining and the error are reduced.

Description

technical field [0001] The invention relates to the communication technology of electric power equipment, in particular to an MMS-based data interaction method and system between a dispatching master station and a substation. Background technique [0002] With the development of computer technology and the continuous progress of power systems, power systems have higher and higher requirements for information sharing and application integration. To this end, the International Electrotechnical Commission has formulated a series of electrical standards, including the IEC 61970 standard and the IEC 61850 standard. [0003] The IEC 61970 standard defines an application program interface for the Energy Management System (EMS, Energy Management System), the purpose is to facilitate the integration of various applications within the EMS of different manufacturers, and to facilitate the interconnection of the EMS with other systems within the dispatch center, so as to realize Model ...

AI Technical Summary

Problems solved by technology

First of all, because the smart substation is based on the IEC 61850 standard and uses MMS for real-time data interaction, and the real-time data interaction with the dispatching master station still uses the traditional protocol method, which brings an additional work--61850 MMS The transformation of the communication method to the traditional protocol method; secondly, because the traditional protocol method does not support the object-oriented modeling method, the object of IEC 61850 must be converted into several information points, thus bringing complex communication information points to both parties Configuration work and information point maintenance work greatly increase the difficulty of debugging and maintenance, and indirectly increase the probability of communication errors; finally, due to various reasons, the conversion of IEC 61850 objects into traditional protocol methods requires When the information points, information loss occurs or the dispatching master station system cannot fully view the real-time data of all objects in the smart substation.
