Description

  The present invention relates to a supervisory control system, and more particularly to a status display method of the supervisory control system.

  In a monitoring control system, an operator is informed by displaying on the display screen an interlock determination result for determining whether or not a control operation of each monitoring control target can be performed from status information of a plurality of monitoring control targets to be monitored and controlled. (Patent Document 1).

  In addition, the supervisory control system displays an overall system diagram that symbolizes the entire power system on the display screen, and when a switchgear operation or abnormality occurs due to a system fault, a device symbol corresponding to the switchgear is displayed in flicker. By doing so, there is something that informs the operator (Patent Document 2).

  However, according to the above conventional technique, only the result of the interlock determination is displayed on the display screen, and thus the current conditions of the interlock conditions and various conditions cannot be confirmed on the display screen. For this reason, when the interlock condition is satisfied when the control operation is performed, the operator needs to investigate the current state of the various conditions with reference to the drawings and the like, and the treatment after the interlock condition is satisfied cannot be performed smoothly. There was a problem.

  In addition, according to the above-described conventional technique, when the entire system diagram is displayed on the display screen, the device symbols are reduced due to display space restrictions. For this reason, there is a problem that it is difficult to distinguish a device symbol that has changed state from a device symbol that does not change state even if flicker display is performed.

  This invention is made in view of the above, Comprising: It is 1st to obtain the monitoring control system which can confirm the interlock condition at the time of interlock determination, and the present condition of various conditions on a display screen. Objective.

  A second object of the present invention is to obtain a monitoring control system capable of improving the visibility of a device symbol whose state has changed on the entire system diagram.

  In order to solve the above-described problems and achieve the object, the monitoring control system of the present invention includes an interlock determination processing unit that determines whether the control operation of the monitoring control target is possible based on the state of the monitoring control target, An interlock state display processing unit that performs display processing of whether or not the control operation of the monitoring control target is possible based on a determination result by the interlock determination processing unit, and whether or not the control operation of the monitoring control target is possible and the conditions used for the determination And an interlock condition display processing unit for displaying the relationship between the

  According to the present invention, there is an effect that it is possible to check the interlock condition at the time of interlock determination and the current state of various conditions on the display screen.
