Description

[Technical field]

[0001] The present application relates to a supervisory control system. [Background technology]

[0002] A monitoring and control system is a system that monitors and controls a monitoring target that consists of a number of facilities such as plants, water supply and sewerage, power systems, etc. Among them, a power system monitoring and control system is a system for monitoring and controlling a number of facilities such as power transmission lines, switches, substation equipment, and generators, and has a display device that can display the many facilities of the monitoring target.

[0003] There are several types of display devices incorporated into this power system monitoring and control system depending on the purpose. Among them, there is a display device that displays a diagram representing the equipment (hereafter referred to as equipment) for the entire power system under the jurisdiction of a single power system monitoring and control system, for the purpose of grasping the whole picture of the numerous pieces of equipment that make up the power system, and this is called a system monitoring panel.

[0004] Since the system monitoring panel also has the purpose of allowing multiple operators (operators of the power system monitoring and control system) to share the status of the equipment in the entire power system, a large display area is required, and a large screen monitor or a combination of multiple monitors is used.

[0005] On the other hand, in order to operate the power system monitoring and control system while keeping the entire display of the system monitoring panel in view, the operator performs operations (monitoring and control) on a device called an operation console that is located a certain distance away from the system monitoring panel.

[0006] In a power system monitoring and control system, if the jurisdiction area (scope of the power system) that is the subject of monitoring and control has a complex configuration and the number of facilities to be displayed on the system monitoring panel increases, it is necessary to expand the display area of ​​the system monitoring panel. However, if expansion is not possible, it is necessary to display the facilities on the system monitoring panel in a small size. This leads to problems with poor visibility of the system monitoring panel when the equipment configuration of the jurisdiction area is complex, leading to problems with poor work efficiency when the operator operates it. Another problem is that poor visibility of the system monitoring panel makes it easier for operators to make operational errors.

[0007] To address this issue, it is known that in order to avoid missing status changes in complex jurisdictional areas, equipment symbols corresponding to monitoring and control objects that have been determined to have a status change are highlighted on the system monitoring panel to improve visibility (see, for example, Patent Document 1).

[0008] It has also been disclosed that two display devices are placed on the console used by the operator, one for the operator and the other for displaying a specified partial screen, making screen selection easier and improving visibility (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

Alternatively, there is a problem that attention is drawn to the highlighted display, and monitoring on the system monitoring panel is neglected.

[0011] In Patent Document 2, although the screen specified by each individual operator can be displayed immediately, there is a problem in that the information cannot be shared among a plurality of operators.

[0012] The present application discloses technology for solving the problems described above, and aims to provide a power system monitoring and control system that can monitor the entire area under its jurisdiction, share information on status changes, etc. among multiple operators, and improve visibility. [Means for solving the problem]

[0013] The monitoring and control system disclosed in the present application includes a system monitoring panel capable of displaying a system monitoring panel image, which is an image showing the overall equipment status of a power system in a jurisdiction area that is the subject of monitoring and control, an image output device that receives information on each piece of equipment in the power system in the jurisdiction area, creates the system monitoring panel image, and outputs the system monitoring panel image to the system monitoring panel, a monitor that is installed adjacent to the system monitoring panel and has a display area smaller than that of the system monitoring panel, and an image pattern to be displayed on the monitor. A part of the display range of the system monitoring panel image is displayed, and a plurality of images showing the equipment status of a part of the equipment of the power system in the jurisdiction area are displayed in advance. and an operation console for registering the image output device. Well, the above The image output device is By the signal from the console, Noboru and displaying a selected image pattern from the plurality of image patterns recorded on the monitor, and when receiving a signal indicating an abnormality in the power system equipment in the jurisdiction area, selecting an image pattern including an abnormality occurrence location from the plurality of image patterns registered. On the monitor Automatically It is configured to display Effect of the Invention

[0014] According to the monitoring and control system disclosed in the present application, by placing a display device adjacent to the system monitoring panel, it is possible to obtain a power system monitoring and control system that can monitor the entire area under its jurisdiction while multiple operators can share information such as status changes and improve visibility. [Brief description of the drawings]

[Diagram 2] 2 is a diagram showing a display state of a monitor in the power system monitoring and control system according to the first embodiment. FIG. [Diagram 3] 1 is a hardware configuration diagram of a power system monitoring and control system according to a first embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the monitoring and control system disclosed in the present application will be described with reference to the drawings. In the following, a power system monitoring and control system will be described as a representative example of the monitoring and control system, but the present invention is not limited to a power system as long as multiple facilities such as plants, water supply and sewerage systems, etc. are monitored as a series of facilities. In addition, the same reference numerals in each drawing indicate the same or corresponding parts.

[0017] Embodiment 1 The power system monitoring and control system according to the first embodiment will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a power system monitoring and control system according to the first embodiment, and FIG. 2 is a diagram for explaining an example of a display state of a monitor provided in the power system monitoring and control system. The power system monitoring and control system 1 comprises a system monitoring panel 14 capable of displaying the entire jurisdiction area that is the subject of monitoring and control, an image output device 12 that receives information on each piece of power system equipment in the jurisdiction area that is the subject of monitoring and control via an external network 2 and outputs images to the system monitoring panel 14, an operation console 18 that an operator operates to perform control, and a monitor 16 that is installed adjacent to the system monitoring panel 14 and has a smaller display area than the system monitoring panel 14.

[0018] The image output device 12 is actually a group of several to several tens of computers, each equipped with an arithmetic unit, a storage unit, an operation device, a display unit, etc., connected via an information network. Here, they are collectively treated as the image output device.

[0019] Furthermore, the image output device 12 is connected to the system monitoring panel 14, the operation console 18, and the monitor 16 via a network within the power system monitoring control system 1. The image output device 12 creates an image showing the equipment status of the entire power system in its jurisdiction based on information on the equipment status of the power system in its jurisdiction area acquired from the external network 2. Hereinafter, this image will be referred to as a system monitoring panel image. The image output device 12 periodically updates the system monitoring panel image to the latest status based on the information it periodically acquires, and transmits it to the system monitoring panel 14.

[0020] The system monitoring panel 14 is a device equipped with a computer that serves as an image receiving section and an image display section. The system monitoring panel 14 periodically receives system monitoring panel images from the image output device 12 via the network within the power system monitoring control system 1. The system monitoring panel 14 displays the received system monitoring panel images. In other words, the system monitoring panel 14 displays an image showing the latest equipment status of the entire power system within its jurisdiction.

[0021] The operation console 18 is equipped with a computer and a display unit used by the operator for operation and control, and in this embodiment, an image pattern to be enlarged and displayed on the monitor 16 adjacent to the system monitoring panel 14 is created and registered in the image output device 12. The operator can select a registered image pattern and press a specific button on the operation console 18 to read out the image pattern registered in the image output device 12 and display it enlarged on the monitor 16.

[0022] In FIG. 2, for example, when operator A notices an abnormality in the equipment and presses a predetermined button on the operation console 18, a display request signal is sent from the operation console 18 to the image output device 12, and a selected image pattern from among preregistered image patterns is read from the image output device 12 and enlarged and displayed on the monitor 16. Operator A can check the enlarged and displayed abnormal part on the monitor 16 while monitoring the equipment status of the entire power system in the jurisdiction area displayed on the system monitoring panel 14. At the same time, if there are multiple operators, the equipment information recognized as an abnormal part by operator A can be enlarged and displayed on the monitor 16, and the information can be shared with operator B. Operator B can also continue to monitor the equipment status of the entire power system in the jurisdiction area displayed on the system monitoring panel 14.

[0023] As shown in FIG. 2, the monitor 16 should be placed next to the system monitoring panel 14, for example, side-by-side so that an enlarged display of points of interest can be confirmed in accordance with the equipment status of the entire power system within the jurisdiction area.

[0024] Image patterns that can be registered in advance in the image output device 12 from the console 18 include locations where abnormalities have occurred, locations requiring daily inspection, locations requiring periodic inspection, and the like. Display on the monitor 16 is not limited to pressing a button on the console 18, and emergency situations such as the occurrence of an abnormality may be automatically displayed on the monitor 16 from the image output device 12. The occurrence of an abnormality includes the occurrence of an accident and the occurrence of an abnormal event that may lead to an accident.

[0025] As described above, according to the power system monitoring and control system of the first embodiment, the monitor 16 having a smaller display area than the system monitoring panel 14 is installed adjacent to the system monitoring panel 14 capable of displaying the entire jurisdiction area to be monitored and controlled, and an enlarged image of a point of interest read out from an image pattern registered in advance in the image output device 12 is displayed on the monitor 16, so that a system monitoring and control system can be obtained in which multiple operators can share information such as status changes while monitoring the entire jurisdiction area, and visibility can be improved. Furthermore, improved visibility has the effect of improving the work efficiency of the operators and preventing erroneous operations.

[0026] Since the monitor 16 having a smaller display area than the system monitoring panel 14 is installed, it is possible to improve visibility at a lower cost than by updating the system monitoring panel 14 to one having an enlarged display area.

[0027] Furthermore, since the image to be enlarged and displayed is registered in advance as an image pattern, when an abnormality or accident occurs, the relevant portion can be quickly enlarged and displayed, enabling a quick response.

[0028] A monitor is installed adjacent to the system monitoring panel 14, so that it is possible to check enlarged areas of interest corresponding to the equipment status of the entire power system within the jurisdiction area, and it is also possible to respond to the location of an accident while continuing to monitor the entire system. Furthermore, since a monitor is installed adjacent to the system monitoring panel 14, information on the location of an abnormality or accident can be easily shared among multiple operators.

[0029] The power system monitoring and control system 1 is configured with a processor 100 and a storage device 200, as shown in FIG. 3, which is an example of hardware. Although the storage device is not shown, it includes a volatile storage device such as a random access memory and a non-volatile auxiliary storage device such as a flash memory. Also, instead of the flash memory, an auxiliary storage device such as a hard disk may be included. The processor 100 executes a program input from the storage device 200. In this case, the program is input from the auxiliary storage device to the processor 100 via the volatile storage device. Also, the processor 100 may output data such as a calculation result to the volatile storage device of the storage device 200, or may store the data in the auxiliary storage device via the volatile storage device. Also, the image output device 12, the system monitoring panel 14, and the operation console 18 of the power system monitoring and control system 1 may each have a hardware configuration as shown in FIG. 3.

[0030] Although exemplary embodiments are described herein, the various features, aspects, and functions described in the embodiments are not limited to application to a particular embodiment, but may be applied to the embodiments alone or in various combinations. Therefore, countless modifications not exemplified are assumed within the scope of the technology disclosed in the present specification, including, for example, modifying, adding, or omitting at least one component, and further, extracting at least one component and combining it with a component of another embodiment.
