基于数据分类的JENA法在CIM的应用研究

Application and Research of the JENA in CIM Based on Data Partitioning

公共信息模型CIM定义了用于不同电力系统间交互数据的一个通用模型。在开发基于CIM数据模型的电力系统中,为实现电力系统的标准化集成,解决"信息孤岛"问题,需要在关系型数据库中对CIM数据模型进行导入导出操作。本文讨论的基于数据分类的JENA法,是为实现这种导入导出操作而对JENA法的一种改进。它是在JENA法的基础原理上,针对电力系统自身的实际情况,引入数据分类的思想,通过对电力系统不同性质的数据进行分类管理。实验验证结果表明这种方法可行有效且具有数据处理简单快捷、减轻网络负担和增大数据传输速度等优点。

CIM （Common Information Model） provides a common model for exchanging data in different power system. In the development of power system based on CIM data model, in order to implement the standard integration in power system and make data exchange easily, the CIM needs import and export from the relational database. This article studies an improved method which is the JENA based on data partitioning, saving the data by partition method through their different characteristics in power system of practical situation. Verification results shows that the method discussed in this article is reasonable and effective, and has some advantages of processing data easily and quickly, reducing the heavy burdens of network, increasing data rate.
