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.

具体实施方式Detailed ways
下面结合附图对本发明作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。 The invention is further described below in conjunction with the drawings. The following examples are only intended to more clearly illustrate the technical solutions of the present invention, and are not intended to limit the scope of the present invention.
国际电工委员会TC57的WG14制定了IEC 61968系列标准，其中信息交换模型基于CIM模型生成具体的业务子集，并以XML Schema、RDFS或SVG等规定具体的业务数据格式。CIM采用UML(Unified Modeling Language统一建模语言)标记语言定义，用来描述现实世界中电力***的设备和功能。但是，因为UML作为一种通用建模语言而过于通用、复杂，现在还难以从UML模型生成完整的应用***。元建模技术是解决这个问题的方法之一，其核心思想是由领域专家按需定制领域建模语言，然后通过代码生成技术自动获得支持该领域建模语言的建模工具。元模型是对模型的抽象，元模型与元模型之间的相互映射、相互交换元数据是通过一种MOF定义的公共的抽象语言来实现的。数据的语义由模型来描述，模型的语义由元模型来描述，元模型的语义由MOF来描述。数据的语义最终可以在MOF这一层次被最终表达，这种表达方式是所有元模型的通用表达。WG14 of the International Electrotechnical Commission TC57 has developed the IEC 61968 series of standards, in which the information exchange model generates specific business subsets based on the CIM model and specifies specific business data formats in XML Schema, RDFS or SVG. CIM uses the UML (Unified Modeling Language) markup language definition to describe the devices and functions of the power system in the real world. However, because UML is too general and complex as a general-purpose modeling language, it is now difficult to generate complete applications from UML models. Meta-modeling technology is one of the methods to solve this problem. The core idea is that the domain experts can customize the domain modeling language on demand, and then automatically obtain the modeling tools that support the domain modeling language through code generation technology. The metamodel is an abstraction of the model. The mutual mapping between the metamodel and the metamodel and the exchange of metadata are realized by a common abstract language defined by MOF. The semantics of the data are described by models. The semantics of the model are described by a metamodel, and the semantics of the metamodel are described by MOF. The semantics of the data can ultimately be expressed at the MOF level, which is the universal expression of all metamodels.
如图1所示，一种基于IEC61968标准信息交互总线的配电网故障抢修***数据共享方法，包括以下步骤：As shown in FIG. 1 , a data sharing method for a distribution network fault repair system based on the IEC61968 standard information interaction bus includes the following steps:
步骤一，故障快速抢修指挥业务应用***将各自采集的数据作为数据模型信息，由元模型生成组件以MOF规范按照四层元数据结构再将数据模型信息抽象生成元模型。Step one, the fault rapid repair command business application system uses the data collected by each as data model information, and the metamodel generation component abstracts the data model information into a metamodel according to the four-layer metadata structure according to the MOF specification.
现有的故障快速抢修指挥业务应用***包括以下子***：95598***、GIS***、用电信息采集***、配电生产管理***、配电自动化***、移动作业终端。每个子***抽象生成相应的元模型。The existing fault rapid repair command business application system includes the following subsystems: 95598 system, GIS system, power information collection system, power distribution production management system, distribution automation system, and mobile operation terminal. Each subsystem abstract generates a corresponding metamodel.
其中95598***是电力客户服务***，其建立在一系列自动化***上，集电话和传真多种媒体的计算机集成***。当用户遇到用电故障时，能够向95598报修。The 95598 system is a power customer service system built on a series of automated systems, a computer integrated system that combines telephone and fax media. When the user encounters a power failure, he can report to 95598 for repair.
GIS***给出故障区域的地理图、单线图、***网络图。同时利用GIS中低压终端表箱与客户电能表编号统一耦合，实现电网从变电站到每个电力客户间物理信息的GIS空间关联。The GIS system gives a geographic map, a single line graph, and a system network map of the fault area. At the same time, the GIS medium-voltage low-voltage terminal meter box and the customer energy meter number are uniformly coupled to realize the GIS spatial correlation of the physical information of the grid from the substation to each power customer.
步骤二，将包含有数据模型信息和元模型描述信息的元模型发送到基于IEC61968标准的配电网信息交互总线上，元模型描述信息包含数据模型类、文件属性、数据模型间的关系。Step 2: The metamodel including the data model information and the metamodel description information is sent to the distribution network information interaction bus based on the IEC61968 standard, and the metamodel description information includes the relationship between the data model class, the file attribute, and the data model.

The GIS system sends the distribution equipment information and the spatial position information of the distribution lines. The electricity information collection system sends the distribution transformer power alarm information. The distribution automation system sends the remote signal and telemetry. And load information, the distribution production system sends the distribution equipment ledger, power outage plan, defects and maintenance information.
步骤三，移动作业终端通过元模型描述信息识别，并从配电网信息交互总线提取所需文件，由元模型转换组件按照PMDL规则将模型定义转换为程序可理解的XML文本。 Step 3: The mobile work terminal identifies the information through the metamodel description, and extracts the required file from the distribution network information interaction bus, and the metamodel conversion component converts the model definition into the XML text understandable by the program according to the PMDL rule.
同时GIS***下载配电设备实时信息，95598***下载抢修进度计划和非计划停电信息。移动作业终端下载抢修工单、作业指导书。At the same time, the GIS system downloads the real-time information of the power distribution equipment, and the 95598 system downloads the repair schedule and the unplanned power outage information. The mobile work terminal downloads the repair work order and the work instruction book.
假设需要令故障快速抢修指挥业务中95598***发送抢修工单到移动作业终端，步骤如下：Assume that the 95598 system in the fault rapid repair command service is required to send the repair work order to the mobile operation terminal. The steps are as follows:
A1，95598***和移动作业终端被抽象成两个信息对象，交互的信息即为故障抢修工单，将其视为一个文件。各个子***将采集到的基础数据作为数据模型信息；由元模型生成组件以MOF规范按照四层元数据结构将数据模型信息进行抽象进一步描述成为元模型。95598***获得的数据信息中包含故障抢修工单。The A1, 95598 system and the mobile work terminal are abstracted into two information objects, and the interactive information is the fault repair work order, which is regarded as a file. Each subsystem uses the collected basic data as data model information; the metamodel generation component further abstracts the data model information into a metamodel according to the four-layer metadata structure in the MOF specification. The data information obtained by the 95598 system contains the fault repair work order.
A2，将包含有数据模型信息和元模型描述信息的元模型发送到基于IEC61968的故障快速抢修指挥信息交换总线上；95598***发送抢修工单文件时需要对文件进行描述，然后发送至信息交换总线；A2, the metamodel containing the data model information and the metamodel description information is sent to the fault fast repair command information exchange bus based on IEC61968; when the 95598 system sends the repair work order file, the file needs to be described and then sent to the information exchange bus. ;
A3，移动作业终端通过元模型中的描述信息从配电网信息交互总线提取所需的文件，由元模型转换组件按照PMDL规则将模型定义转换为程序可理解的XML文本；移动作业终端下载故障抢修工单信息文件，同时生成故障快速抢修命令。A3, the mobile work terminal extracts the required file from the distribution network information interaction bus through the description information in the metamodel, and the metamodel conversion component converts the model definition into the XML text understandable by the program according to the PMDL rule; the mobile operation terminal downloads the fault The repair work order information file is generated, and the fault quick repair command is generated at the same time.
