Optimal load distributing system

Abstract

To provide an operation schedule that minimizes the fuel cost that involves a minimum number of input parameters, is calculated offline, and is arranged taking into account the output distribution among a plurality of units that minimizes the fuel cost. An optimal load distributing system for managing an optimal load distribution of a total output of a power plant composed of a plurality of units among the plurality of units has: a data inputting part 1 that is used for inputting plant specifications of each unit required for optimal load distribution; an optimal load distribution input file 2 that stores data input via the data inputting part; an optimal load distribution calculating part 3 that carries out an optimal load distribution calculation based on data stored in the optimal load distribution input file; an optimal load distribution output file 4 that stores the result of the calculation carried out by the optimal load distribution calculating part; an optimal load distribution pattern displaying part 5 that displays a sending-end characteristic curve for each unit, a fuel cost curve for each unit, a curve of the load optimally distributed to each unit versus the total output, a fuel cost curve for the total output, and fuel cost curves for comparison between a conventional load distribution and the optimal load distribution based on data stored in the optimal load distribution output file and the optimal load distribution input file; and an optimal load distribution schedule displaying part 6 that displays a power transmission time schedule table, a power transmission time schedule curve, and a fuel cost comparison table for different operating schemes.
