Document Type and Number:
WIPO Patent Application WO/2021/106328
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a plant operation support system which, for each control variable, can present a set value range which has a proven operation record and high reliability. This plant operation support system (1) is provided with: a category generation unit (502) which uses past operation data, including set values of control variables, to sort past operation data into categories with past disturbance information as parameters; a normal operation data extraction unit (503) which, for each of said categories, extracts operation data of times when the plant (301) has been operated normally; a set value range derivation unit (504) which, for each of said categories, uses the extracted operation data to derive a range of set values in each control variable within which normal operation has been carried out; and an operation condition presentation unit (505) which derives categories to which current disturbance information belongs and presents the range of set values for each of the control variables for the derived categories.
