Application of Multi-dimensional Data Modeling in EMS System
Yin Shou-ya · Northeast Electric Power Technology · 2015
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.
