Analysis of the DCS Historical Data for Estimation of Input Signal Significance

The paper is on technological parameters data processing and analysis for further input signal significance estimation. In the paper the data retrieving from distributed control system software and hardware complex historical database is described and the algorithm of data formatting and processing is presented along with the examples. The problem of input signal impact on thermal power plant technical-and-economic indices is addressed in the research. The chosen data analysis tools are described and the plots and diagrams used to illustrate the data are presented. The novel parameter and group of parameters visualization approach is introduced. The possible ways of automating the database interaction and data analysis are proposed.
