<p>PROBLEM TO BE SOLVED: To control a power flow to be a forward flow which is a little larger than the demand power of important loads by a method wherein a generator output control means which controls the output of a private generator so as to have the power flow of a bus-bar be a power flow which is smaller than a predetermined value and flows an important load side to a general load side in a linking operation in accordance with the monitoring of a power flow monitoring means. SOLUTION: When the power of a bus-bar 1 is a forward flow exceeding the upper limit value of a reference terminal, an OR gate supplies the reduction command or increase command of a private generator output to an operating unit 14. In accordance with the command, the operating unit 14 changes the output of the private generator 13 in a reducing direction or increasing direction step by step. The output of the private generator 13 is controlled so as to have the power of the bus-bar 1 always be a forward power flow which is smaller that the upper limit value of a reference terminal. With this constitution, when a system power supply 9 and the private generator 13 are linked with each other for operation, the output of the private generator 13 can be always controlled to be a forward power flow a little larger than the hourly demand power of important loads.</p> |
