Patent Searching and Data


Title:
プラント運用制御装置
Document Type and Number:
Japanese Patent JP4099334
Kind Code:
B2
Abstract:

To efficiently and stably perform plant operation by fast performing an arithmetic operation about an optimum operation plan with high accuracy even though a plant to be controlled is complex or of a large scale.

A process data storing part 4 stores a measurement value of process data obtained through a process controller 2 and data, such as various parameter setting values. A demand predicting part 5 predicts quantity demanded per unit time on the operating day for one day on the basis of the actual results of past demanding places obtained from the process data storing part 4 or weather information and other data. An operation planning part 6 calculates a device start and stop plan per unit time on the day on the basis of the quantity demanded per unit time for one day predicted by the demand predicting part 5 and the measurement value of the process with a genetic algorithm encoded by an integer gene.
