PURPOSE:To reduce the generating cost and improve the operation control of the group of a plurality of power stations by collectively controlling the operation of each power station from one centralized operation management device through digital high-speed transmission lines. CONSTITUTION:Each input-output device 2 is connected to a plurality of power stations 1 having the same function. Then each data management device 3 is connected to each input-output device 2 so that process signals can be collected and control signals can be transmitted from and to each power station 1. In addition, each data management device 3 is connected to a centralized operation management device 4 so that the operation of each power station 1 can be controlled on the basis of process or control signals from each power station 1 and power generation demands through a digital high-speed transmission line 5. Therefore, the generating cost can be reduced and the operation control and operation management can be improved, since the power output control and abnormality are not coped with individually by each power station. |
