Operation condition evaluation apparatus, operation condition evaluation method, and control system for boiler

Abstract

An operation condition evaluation apparatus to evaluate operation condition of a boiler comprises an operation mode input section to receive an operation mode input of the boiler, a behavior model storage section to store behavior models indicating virtual behaviors of the boiler, a simulation section to apply the operation conditions to the behavior models and to compute virtual process values of the boiler, the operation conditions including a set of operation parameters which is set to each of plural manipulation ends provided with the boiler, a weighted coefficient storage section to store a weighted coefficient defined correspondingly to the operation mode for each of the virtual process values, and a score calculation section to determine the weighted coefficient corresponding to the input operation mode and to calculate an evaluation score of the operation conditions respectively based on a value obtained by multiplying the virtual process values by the weighted coefficient.
