<p>PURPOSE:To simplify a system and to reduce its cost by adding a sequence monitoring function which can easily confirm the progress state of the operation of a thermal power generation plant. CONSTITUTION:The sequence controller 1 for the thermal power plant which controls auxiliary machines in subloop units for the plant operation of the thermal power plant is provided with a monitoring processing unit 13 having the sequence monitoring function which can display and confirm the progress state of the sequence of the plant operation on a display device 14 at every breaking point. Operation progress data are sent, subloop by subloop, from sequence control units 2-4 to the monitoring processing unit 13 in the sequence controller 1 through a communication line 6. The monitoring processing unit 13 edits the operation progress data of the respective subloops into sequence monitoring data, which are displayed 14 as, for example, the sequence numbers of the subloops. The system if therefore simplified to reduce the cost.</p> |
