摘要： PROBLEM TO BE SOLVED: To provide a generator output estimation method, and a system and a program thereof, which dispense with measurement because of frequent interruption of a generator even if there is secular and seasonal load fluctuation once a regression equation is acquired.SOLUTION: The estimation method of an output of a generator includes a first step for measuring electric quantity in an objective distribution line section, a second step for calculating a positive phase current and reverse phase current during a period while the generator is suspended, a third step for acquiring a regression equation of the positive phase current and the reverse phase current, a fourth step for acquiring a reverse phase current in a distribution line section, a fifth step for calculating an estimated value of the positive phase current during the period the generator is suspended, a sixth step for acquiring a positive phase current in the distribution line section during a period the generator is operated, and a seventh step for calculating a current deviation which is an output current of the generator. The regression equation of the positive phase current and the reverse phase current acquired in the third step is appropriately changed according to a secular and seasonal load fluctuation.
