中文摘要:由于缺乏有效管理手段，导致电网通信资源数据的完整性、一致性、有效性无法保障，影响电网通信专业服务质量。为此，提出了基于元数据的电网通信资源数据校核方法。该方法分为三个过程：利用网络捕包得到电网通信资源数据，将捕获的数据存入磁盘列阵内和电网通信资源数据多层次校核。多层次校核内的信息层校核将XSD推荐标准作为元数据实施驱动，利用XSD校核引擎实现信息校核；模型层校核将元数据模型内同公共信息模型OWL描述的本体文件作为元数据，校核电网通信网络各系统资源信息内提取的RDF格式模型实例；数据层校核以元数据模型内拓扑规则元数据作为校核依据，校核电网各系统中常见的孤岛、内外环等拓扑结构问题。实验结果表明：所提方法能有效验证电网通信资源数据的一致性、有效性和完整性，且校核精度较高达95%以上。

Data Checking Method of Power Network Communication Resources Based on Metadata

Abstract:Due to the lack of effective management means，the integrity，consistency and validity of power grid communication resources data can not be guaranteed，which affects the quality of service of power grid communication profession. To solve this problem，a metadata-based data verification method for power network communication resources is proposed. The method is divided into three processes：using network packet capturing to get the data of power grid communication resources，storing the captured data into disk array and multi-level verification of power grid communication resources data. Information layer verification in multi-level verification uses XSD recommendation standard as metadata driver and XSD verification engine to realize information verification. Model layer verification uses ontology files described by metadata model and public information model OWL as metadata to verify RDF format model extracted from the resource information of each system in nuclear power network communication network. Examples：Data layer checking is based on the metadata of the topological rules in the metadata model to check the common topological structure problems such as islands，inner and outer rings in various systems of nuclear power network. The experimental results show that the proposed method can effectively verify the consistency，validity and integrity of power grid communication resource data，and the verification accuracy is higher than 95%.
