<P>PROBLEM TO BE SOLVED: To improve operational efficiency while managing upper limit values such as a maximum output more strictly in a power station. <P>SOLUTION: A control device for a powers station includes: an electrical energy integration section for determining an integral value of instantaneous values of generated output as an integral electrical energy at every integration period; a first desired value calculation section for calculating a first desired integral value that is a desired value of integral electrical energy; a first subtraction section for subtracting a first desired instantaneous value that is a predetermined desired value from the instantaneous value of generated output to determine a first difference; a second subtraction section for subtracting the first desired integral value from the integral electrical energy to determine a second difference; and a first determination section for outputting a control signal to control power generation equipment such that the integral electrical energy matches the first desired integral value at the end of the current integration period on the basis of the first and second differences. If the second difference is positive at the end of the current integration period, the first desired value calculation section subtracts a value equal to or greater than the second difference from the first desired integral value at the end of the current integration period in determining the first desired integral value at the end of the next integration period. <P>COPYRIGHT: (C)2013,JPO&INPIT |
