摘要
目前调控一体化系统所使用数据模型全部是关系型模型,关系型模型具备良好的扩展性,通用性强,但难以支持多维观察、数据钻取以及复杂的多维数据集运算等功能。对BI技术的建模思想进行介绍,然后结合电网调控系统的目前数据结构方式以及存在的不足进行分析,并提出基于BI的建模思想对电网调控的数据模型进行重新构造,建立一种电网调控多维方式的数据模型,同时分析多维数据模型在电网调控中应用的优势,为电网调控数据建模方式以及分析方式提供参考。
Multi-dimensional modeling methods of BI technology,to change the current EMS system using the data model is the relational model. The relational model has good expansibility,strong universality,but it is difficult to support multi-dimensional data,multi-dimensional observation,data drill and complex set of operations and other functions. The modeling idea of BI technology is introduced,and analysis is made combining with the current EMS system data structure mode and the existing shortcomings,Reconstruction of the grid regulation data model based on BI modeling is put forward,a multi-dimensional way of regulating the grid data model is established. At the same time the application analysis of multi-dimensional data model in grid control advantages is made,providing the reference for the data modeling and analysis of grid control mode.
