Abstract
Disclosed is a power distribution network fault repair system data sharing method for an information exchange bus based on IEC 61968 standards. The method is such that, with data collected by subsystems serving as data models, a metamodel generating component abstractly generates a metamodel from the data models according to a four-layer metadata structure per the MOF standard. The metamodel comprising data model information and metamodel description information is transmitted to an IEC 61968-based power distribution network information exchange bus. A mobile operation terminal identifies via the metamodel description information and extracts from the power distribution network information exchange bus a required file, and a metamodel converting component converts a model definition into a program-understandable XML text according to the PMDL standard. The present invention implements rapid fault repair commanding service interoperation between different service systems, abstracts two information exchanging systems into two information objects, and views exchanged information as one file, thus facilitating system integration and information exchange.

DETAILED DESCRIPTION
The present invention is further described hereinafter with reference to the drawing. The following embodiments are merely used to more clearly illustrate the technical solutions of the present invention, and cannot limit the protection scope of the present invention.
DESCRIPTION
WG14 of the International Electrotechnical Commission TC57 has formulated IEC 61968 series standards, a specific service subset is generated by an information interaction model based on a CINI model, and specific service data format is regulated by xmL Schema, RDFS or SVG. CTIM uses a UN/IL (Unified Modeling Language) markup language definition to describe the device and function of the electricity system in the real world. However, since UNIL is too general and complex as a general modeling language, it is now difficult to generate a complete application system from the UML model. Metamodeling technology is one of the methods to solve this problem, the core idea thereof is that the domain experts customize a domain modeling language according to requirement, and then automatically obtain modeling tools that support the domain modeling language through the code generating technology. The metamodel is the abstraction of the model, the mutual mapping and mutual exchange of metadata between the metamodels are implemented by a common abstract language defined by N1OF. A semanteme of data is described by a model, a semanteme of the model is described by a metamodel, and a semanteme of the metamodel is described by the MOF. The semanteme of data can finally be expressed at the MOF level, which is the general expression of all metamodels.
As shown in Fig. 1, a data sharing method for a distribution network failure repair system of an information interaction bus based on IEC61968 standard includes the following steps.
In a first step, application systems of quick failure repair conducting services use data respectively as data model information, and the data model information is abstractly generated into a metamodel by a metamodel generating component with an MOF specification according to a four-level metadata structure.
The existing application system of quick failure repair conducting service includes following subsystems, such as a 95598 system, a GIS system, an electricity consumption information collecting system, a distribution automation system, a distribution production system and a mobile operating terminal. Corresponding metamodel is abstractly generated by each of the subsystems.
The 95598 system is an electricity customer service system that is established on a series of automatic systems, and is a computer integrated system that combines multiple medium, such as telephone and fax. The user can report to 95598 for repair while encountering power failure.
DESCRIPTION
The GIS system gives a geographic map, a single line drawing and a system network diagram of a failure area. At the same time, a GIS medium-and-low voltage terminal meter box is uniformly coupled with an electricity meter number of a customer to realize GIS spatial correlation of physical information from a transformer substation to each electricity customer in the grid In a second step, the metamodel containing data model information and metamodel description information is sent to the distribution network information interaction bus based on lEC61968, and the metamodel description information contains a data model class, a file attribute, and a relationship between the data models The 95598 system sends failure repair information and failure repair work order, the GIS system sends distribution device information and spatial location information of distribution line, the electricity consumption information collecting system sends distribution transforming power-losing alarm information, the distribution automation system sends remote signaling, remote measuring and load information, and the distribution production system sends a distribution equipment ledger, a power-cut plan, and defect and repair information.
In a third step, the identification is conducted by a mobile operating terminal through the metamodel description information, a file needed is extracted from the distribution network information interaction bus, and a model definition is converted into a program-understandable XML text according to a PMDL rule by a metamodel converting component.
At the same time, the GIS system downloads the real-time information of the distribution device, and the 95598 system downloads the repair progress plan and the unplanned power-cut information The mobile operating terminal downloads the repair work order and work instmction.
Assuming that the repair work order needs to be sent to the mobile operating terminal by the 95598 system in the failure repair conducting service, the steps are as follows.
In step Al, the 95598 system and the mobile operating terminal are abstracted into two information objects, and the interacted information is the failure repair work order, which is deem as one file. Each of the subsystems uses the collected basic data as data model information; and the data model information is abstracted by a metamodel generating component with a MOF specification according to a four-level metadata structure, which is further described into the _ s _
DESCRIPTION
metamodel The data information obtained by the 95598 system contains the failure repair work order.
In step A2, the metamodel containing the data model information and the metamodel description information is sent to the quick failure repair conducting information exchange bus based on IEC61968, when the 95598 system sends the repair work order file, the file needs to be described, and then is sent to the information exchange bus In step A3, the mobile operating terminal extracts the file needed from the distribution network information interaction bus through the description information in the metamodel, and a model definition is converted by a metamodel converting component into a program-understandable XIVIL text according to a PMDL rule; and the mobile operating terminal downloads the failure repair work order information file, and generates the quick failure repair command at the same time The quick failure repair conducting service information interaction method based on the metamodel above is modeled through the metamodel, and two systems conducting information interaction are abstracted into two information objects, and the interacted information will be deemed as one file, which can realize complete application system interoperability. The information interaction is realized through the distribution network information interaction bus based on IEC61968, and data collection, processing and storage device of various existing service application systems are fully used, which is simple and convenient; various service application systems have fewer interfaces and flexible operation mode; and the update and modification of a single service application system cannot affect the internal operation of other service application systems.
