ICD模型文件图形化配置形成与处理方案

Scheme of Graphical Configuration and Processing of ICD Model File

针对手工编辑维护模型文件工作量大,容易出错问题,提出一种IEC 61850模型文件站控层图形化建模方案,该方案中装置功能由图形化模块化功能元件组成,元件可由若干逻辑节点组成,在元件内以逻辑节点视图实现数据属性实例和程序变量映射。提出一种过程层数据发送接收的图形化解耦配置建模方法,研发人员先提供典型过程层配置模板,工程人员可根据实际情况修改发送–接收端子图配置,配套的工具软件根据拓扑关系自动形成过程层配置信息。针对模型文件前后变化导致升级工作较大的问题,提出一种模型文件增量更新算法,以智能比较新旧文件差异,最大程度地保留上次配置。上述方案经批量应用,实践表明,可有效提高智能变电站研发和工程实施效率。

A scheme for station level graphical modeling of IEC 61850 model file is proposed for the problems of heavy workload and easy to make errors in manual editing and maintaining model file. In this scheme, device function is composed of graphical and modular component, and the component can be composed of a number of logical nodes. Mapping between data attribute instances and program variable can be realized through logical node view within modular component. The scheme proposes decoupling-configuration modeling approach for data sending and receiving in process level, with which the engineers could accomplish graphical configuration of the send-receive terminals according to practical situation, based on typical configuration templates of process level supplied by R&D personnel, and the matched tools software generates configuration information for process level automatically according to the topological relation. To solve the problem that massive upgrade could be aroused by the altering of model file, an incremental updating algorithm is introduced, which implements intelligent comparison of old file and new file and retains previous configuration to the maximum degree. All the above-mentioned schemes have been widely used in intelligent substations, and practice shows that the schemes could observably improve the efficiency of development and engineering implementation.
