Liying Sui · Techniques of Automation and Applications · 2010
With the wide use of the real/historical-time database in power plant,mass production process data is preserved online in a long time.How to analyze the running law of the process inherented in these data is of great significance for improving the running management and decision-making level of power units.This paper introduces the Business Intelligence OLAP technology into production/historical analysis.First of all,OLAP system structure of power plant units is given.Then the theme of economics,security,environmental protection are designed and an economic analysis example is made.At last,the examples of establishment of thematic data warehouse based on economic conditions analysis are given and OLAP technology to analyze multi-dimensional is used.Examples show that the usage of OLAP technology in power plant to the production process historical data analysis not only can demonstrate the relationship between the data effectively but also reflect the operation status and running law of the process.
