Controller for heat power plant |
摘要 |
A master controller receives a load demand and a plurality of plant data from a heat power plant and outputs command signals on at least two of an electric power, a feed water flow rate, a fuel flow rate, an air flow rate and a recirculation gas flow rate of the plant required to achieve the load demand. A plurality of sub-loop controllers independently provided one for each of the command signals provide control quantities for controlling respective control ends in accordance with the command signals. A transmission loop is arranged between the sub-loop controllers and the master controller. Drive means drive the control terminals provided one for each of the control quantities supplied from the sub-loop controllers. An I/O bus is arranged between one of the sub-loop controllers and the drive means driven by the command signal for the one sub-loop controller. Detection means detect the plant data to be delivered to the master controller or the sub-loop controllers.
