发明内容Contents of the invention
本发明的目的就是为了解决上述问题,提供一种基于模型对象化语义的ICD检验方法,它具有解决ICD文件中各节点依赖关系正确性的校验难题优点。The object of the present invention is to solve the above-mentioned problems, and to provide an ICD verification method based on model object semantics, which has the advantage of solving the verification problem of the correctness of the dependency relationship of each node in the ICD file.
为了实现上述目的,本发明采用如下技术方案:In order to achieve the above object, the present invention adopts the following technical solutions:
基于模型对象化语义的ICD检验方法,主要包括以下步骤:The ICD inspection method based on model object semantics mainly includes the following steps:
步骤(1):按照IEC61850标准Schema模型(XML Schema)建立ICD文件的RDF Schema模型,建立相应的RDF Schema模型的原因是ICD文件中的节点之间存在着密切的依赖关系,适合用面向对象的数据模型来承载;所述RDF Schema模型是中国专利(申请号:201110227408.9,专利名称为:用于智能变电站设计的图形及RDF模型构建方法)里面提到的模型RDF Schema;Step (1): Establish the RDF Schema model of the ICD file according to the IEC61850 standard Schema model (XML Schema). The reason for establishing the corresponding RDF Schema model is that there is a close dependency between the nodes in the ICD file, which is suitable for object-oriented The data model is carried; the RDF Schema model is the model RDF Schema mentioned in the Chinese patent (application number: 201110227408.9, patent name: graphics and RDF model construction method for intelligent substation design);
步骤(2):RDF Schema模型对象化;将所有的ICD文件节点创建为面向对象的RDF数据对象实例,所有ICD文件节点之间的依赖关系也创建为具体的RDF数据对象关联,最终ICD文件中所有的节点将以RDF数据对象的形式存储到面向对象的数据模型中;Step (2): Objectify the RDF Schema model; create all ICD file nodes as object-oriented RDF data object instances, and create dependencies between all ICD file nodes as specific RDF data object associations. In the final ICD file All nodes will be stored in the object-oriented data model in the form of RDF data objects;
步骤(3):节点解析;如果ICD文件节点之间不存在依赖关系,语义校验将直接与事先按照IEC61850特定的数据限制定义建立好的标准规则库进行比对校验;而如果ICD文件节点之间存在依赖关系,语义校验就取出步骤(2)中存储的与该ICD文件节点存在依赖关系的RDF数据对象实例,结合事先按照IEC61850特定的数据限制定义建立好的标准规则库进行综合分析校验;Step (3): Node analysis; if there is no dependency relationship between ICD file nodes, the semantic verification will be directly compared with the standard rule base established in advance according to the specific data limit definition of IEC61850; and if the ICD file node There is a dependency relationship between them, and the semantic verification takes out the RDF data object instance stored in step (2) that has a dependency relationship with the ICD file node, and combines it with the standard rule base established in advance according to the specific data limit definition of IEC61850 for comprehensive analysis check;
步骤(4):得到校验报告。Step (4): Get the verification report.
所述步骤(3)的综合分析校验是根据标准规则库中对数据的限定,进行引用有效性验证,所谓引用有效性即ICD文件中逻辑节点与逻辑节点类型的匹配。所述步骤(3)的综合分析校验与比对校验的区别在于综合分析校验不但要进行ICD文件节点的校验,还需要对ICD文件节点之间的依赖关系进行校验。The comprehensive analysis and verification of the step (3) is to verify the validity of references according to the data limitation in the standard rule base. The so-called validity of references refers to the matching of logical nodes and logical node types in the ICD file. The difference between the comprehensive analysis verification and comparison verification in the step (3) is that the comprehensive analysis verification not only needs to verify the ICD file nodes, but also needs to verify the dependencies between the ICD file nodes.
所述步骤(3)的语义校验分为如下步骤:The semantic verification of the step (3) is divided into the following steps:
步骤(3-1):按照IEC61850标准Schema模型(XML Schema)建立相应的RDF Schema模型;Step (3-1): Establish the corresponding RDF Schema model according to the IEC61850 standard Schema model (XML Schema);
步骤(3-2):解析ICD文件节点,同时创建ICD文件节点的RDF数据对象实例并存储到面向对象的RDF数据模型中,将ICD文件节点之间的依赖关系也以RDF数据对象的形式存储到面向对象的RDF数据模型中,这样在RDF数据模型中将按面向对象的结构存储整个ICD文件节点信息;Step (3-2): Parse the ICD file nodes, create an RDF data object instance of the ICD file nodes and store them in the object-oriented RDF data model, and store the dependencies between the ICD file nodes in the form of RDF data objects into the object-oriented RDF data model, so that the entire ICD file node information will be stored in an object-oriented structure in the RDF data model;
步骤(3-3):如果ICD文件节点之间不存在依赖关系,将直接与事先建立好的标准规则库比对校验;如果ICD文件节点之间存在依赖关系,就从RDF数据模型中取出需要的RDF数据对象进行比对校验。Step (3-3): If there is no dependency relationship between the ICD file nodes, it will be directly compared with the pre-established standard rule base; if there is a dependency relationship between the ICD file nodes, it will be taken from the RDF data model The required RDF data objects are compared and verified.
所述步骤(2)的RDF Schema模型对象化是采用与IEC61850标准Schema模型相同的形式,用RDF描述IEC61850标准Schema模型,给出IEC61850标准Schema模型的RDF Schema;将SCL中的节点智能装置IED、访问点AccessPoint、逻辑设备LDevice、逻辑节点LN分别映射为RDF的智能装置IED模型类、访问点AccessPoint模型类、逻辑设备LDevice模型类、逻辑节点LN模型类;The RDF Schema model objectification of the step (2) adopts the same form as the IEC61850 standard Schema model, uses RDF to describe the IEC61850 standard Schema model, and gives the RDF Schema of the IEC61850 standard Schema model; The access point AccessPoint, the logical device LDevice, and the logical node LN are respectively mapped to the RDF intelligent device IED model class, the access point AccessPoint model class, the logical device LDevice model class, and the logical node LN model class;
所述ICD文件包含模型自描述信息、按工程远景规模配置实例化的DOI元素、数据对象实例DOI;所述数据对象实例DOI包含中文的“desc”描述和dU属性赋值和制造商(manufacturer)、型号(type)、配置版本(configVersion)、虚信号定义等智能装置重要信息,为保证每次变更迭代的ICD文件符合标准规范,以减少由于ICD文件的语法或语义错误带来的重复工作,应按照IEC61850标准和IEC61850《工程继电保护应用模型》规范对厂家提供的ICD模型文件进行语法、语义的校验。The ICD file includes model self-description information, DOI elements instantiated according to project vision scale configuration, and data object instance DOI; the data object instance DOI includes Chinese "desc" description and dU attribute assignment and manufacturer (manufacturer), Important information of smart devices such as model (type), configuration version (configVersion), virtual signal definition, etc., in order to ensure that the ICD file of each change iteration conforms to the standard specification, and to reduce duplication of work caused by syntax or semantic errors in the ICD file, it should be According to the IEC61850 standard and the IEC61850 "Engineering Relay Protection Application Model" specification, the syntax and semantics of the ICD model file provided by the manufacturer are verified.

步骤(1):按照IEC61850标准Schema模型(XML Schema)建立ICD文件的RDF Schema模型,之所以用RDF Schema模型来描述ICD文件中的节点,是因为ICD文件中的节点之间存在着密切的依赖关系,适合用面向对象的数据模型来承载;所述RDF Schema是RDF的词汇描述语言,简言之,RDF描述的是资源与资源之间的关系,而没有定义资源所属的类与类之间的关系,而RDF Schema定义了这方面的约束;所述RDF Schema模型是中国专利(申请号:201110227408.9,专利名称为:用于智能变电站设计的图形及RDF模型构建方法)里面提到的模型RDF Schema。步骤(2):RDF Schema模型对象化;将所有的ICD文件节点创建为面向对象的RDF数据对象实例,所有ICD文件节点之间的依赖关系也创建为具体的RDF数据对象关联,最终ICD文件中所有的节点将以RDF数据对象的形式存储到面向对象的数据模型中;Step (1): Establish the RDF Schema model of the ICD file according to the IEC61850 standard Schema model (XML Schema). The reason why the RDF Schema model is used to describe the nodes in the ICD file is that there are close dependencies between the nodes in the ICD file relationship, which is suitable to be carried by an object-oriented data model; the RDF Schema is the vocabulary description language of RDF. In short, RDF describes the relationship between resources and does not define the class to which the resource belongs relationship, and RDF Schema defines the constraints in this respect; the RDF Schema model is the model RDF mentioned in the Chinese patent (application number: 201110227408.9, patent name: graphics and RDF model construction method for smart substation design) Schema. Step (2): Objectify the RDF Schema model; create all ICD file nodes as object-oriented RDF data object instances, and create dependencies between all ICD file nodes as specific RDF data object associations. In the final ICD file All nodes will be stored in the object-oriented data model in the form of RDF data objects;
步骤(3):节点解析;如果ICD文件节点之间不存在依赖关系,语义校验将直接与事先按照IEC61850特定的数据限制定义建立好的标准规则库进行比对校验;而如果ICD文件节点之间存在依赖关系,语义校验就取出步骤(2)中存储的与该ICD文件节点存在依赖关系的RDF数据对象实例,结合事先按照IEC61850特定的数据限制定义建立好的标准规则库进行综合分析校验;Step (3): Node analysis; if there is no dependency relationship between ICD file nodes, the semantic verification will be directly compared with the standard rule base established in advance according to the specific data limit definition of IEC61850; and if the ICD file node There is a dependency relationship between them, and the semantic verification takes out the RDF data object instance stored in step (2) that has a dependency relationship with the ICD file node, and combines it with the standard rule base established in advance according to the specific data limit definition of IEC61850 for comprehensive analysis check;
步骤(4):得到校验报告。Step (4): Get the verification report.
所述步骤(3)的语义校验分为如下步骤:The semantic verification of the step (3) is divided into the following steps:
步骤(3-1):按照IEC61850标准Schema模型(XML Schema)建立相应的RDF Schema模型;Step (3-1): Establish the corresponding RDF Schema model according to the IEC61850 standard Schema model (XML Schema);
步骤(3-2):解析ICD文件节点,同时创建ICD文件节点的RDF数据对象实例并存储到面向对象的RDF数据模型中,将ICD文件节点之间的依赖关系也以RDF数据对象的形式存储到面向对象的RDF数据模型中,这样在RDF数据模型中将按面向对象的结构存储整个ICD文件节点信息;Step (3-2): Parse the ICD file nodes, create an RDF data object instance of the ICD file nodes and store them in the object-oriented RDF data model, and store the dependencies between the ICD file nodes in the form of RDF data objects into the object-oriented RDF data model, so that the entire ICD file node information will be stored in an object-oriented structure in the RDF data model;
步骤(3-3):如果ICD文件节点之间不存在依赖关系,将直接与事先建立好的标准规则库比对校验;如果ICD文件节点之间存在依赖关系,就从RDF数据模型中取出需要的RDF数据对象进行比对校验。Step (3-3): If there is no dependency relationship between the ICD file nodes, it will be directly compared with the pre-established standard rule base; if there is a dependency relationship between the ICD file nodes, it will be taken from the RDF data model The required RDF data objects are compared and verified.
所述步骤(2)的RDF Schema模型对象化是采用与IEC61850标准Schema模型相同的形式,用RDF描述IEC61850标准Schema模型,给出满足IEC61850标准Schema模型的RDFSchema模型;将SCL中的节点智能装置IED、访问点AccessPoint、逻辑设备LDevice、逻辑节点LN分别映射为RDF的智能装置IED模型类、访问点AccessPoint模型类、逻辑设备LDevice模型类、逻辑节点LN模型类;The objectification of the RDF Schema model in the step (2) adopts the same form as the IEC61850 standard Schema model, uses RDF to describe the IEC61850 standard Schema model, and provides the RDFSchema model that meets the IEC61850 standard Schema model; the node intelligent device IED in the SCL , access point AccessPoint, logical device LDevice, and logical node LN are respectively mapped to the RDF intelligent device IED model class, access point AccessPoint model class, logical device LDevice model class, and logical node LN model class;
所述ICD文件包含模型自描述信息、按工程远景规模配置实例化的DOI元素、数据对象实例DOI;所述数据对象实例DOI包含中文的“desc”描述和dU属性赋值和制造商(manufacturer)、型号(type)、配置版本(configVersion)、虚信号定义等智能装置重要信息,为保证每次变更迭代的ICD文件符合标准规范,以减少由于ICD文件的语法或语义错误带来的重复工作,应按照IEC61850标准和IEC61850《工程继电保护应用模型》规范对厂家提供的ICD模型文件进行语法、语义的校验。The ICD file includes model self-description information, DOI elements instantiated according to project vision scale configuration, and data object instance DOI; the data object instance DOI includes Chinese "desc" description and dU attribute assignment and manufacturer (manufacturer), Important information of smart devices such as model (type), configuration version (configVersion), virtual signal definition, etc., in order to ensure that the ICD file of each change iteration conforms to the standard specification, and to reduce duplication of work caused by syntax or semantic errors in the ICD file, it should be According to the IEC61850 standard and the IEC61850 "Engineering Relay Protection Application Model" specification, the syntax and semantics of the ICD model file provided by the manufacturer are verified.
所述ICD文件通过SCL(Substation Configuration Description Language)变电站配置描述语言进行描述,SCL是IEC61850规定的基于XML的对变电站自动化系统及其结构进行描述的一种语言,它受IEC61850规定的统一的Schema文件约束,如图3所示。The ICD file is described by the SCL (Substation Configuration Description Language) substation configuration description language. SCL is an XML-based language for describing the substation automation system and its structure specified by IEC61850. It is subject to the unified Schema file specified by IEC61850.
