<p><P>PROBLEM TO BE SOLVED: To surely reduce the increment of fuel consumption by power generation while securing necessary electric power generation. <P>SOLUTION: This power generation controller acquires power cost (the increment of fuel consumption per unit electric power generation) by dividing the increment of a fuel consumption rate by power generation by the electric power generation of a generator 16 in specified calculation cycles during the operation of an engine, and computes a target power cost so that the charge/discharge income and expenditure of a battery 12 may be balanced based on data on the use frequency of the power cost, the average of the power cost, the average of a generative quantity, and the average power consumption. At this time, the number of samples is initialized each time when the number of samples of the data used for computation of the target power cost reaches a preset specified number NFClmt (each time one sample section terminates), and stores a final value of data in the memory of a controller 11, and corrects the data in this sample section, using the final value of the data in the last sample section stored in the memory according to the number of samples in this sample section, and computes the target power cost based on the data after correction. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
