Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic user interface and a monitoring control method for a power system, and more particularly to a graphic user interface and a monitoring control method applied to system monitoring.

[0002]

2. Description of the Related Art Monitoring and control devices for electric power systems originate in remote monitoring and control of power plants and substations, and are now widely used as power information control devices having both control system functions and information system functions. . In recent power information control devices, system operation, accident recovery, reliability monitoring, erroneous operation prevention, and the like have been added to the basic monitoring and control functions, and higher speed processing and higher responsiveness have been required. In addition, in order to use the information collected by online monitoring as management information and business support information, the entire power company exchanges and shares the power supply information from the central power supply dispatch office to the lower control stations and sales offices. A system operation related information system has also been realized. The “power system monitoring and control system” in this specification is used in a broad sense including these systems.

[0003] In the power system monitoring and control apparatus of such a large scale, databases distributed to each electric station are connected to a general-purpose network via a server, and can be accessed and used freely from anywhere. Further, in order to speed up the transmission of a huge amount of information, some recent systems draw the system diagram data by receiving a drawing function. On the other hand, a graphic user interface (hereinafter, referred to as a GUI) has been developed which conveys the status of the entire system and allows the user to intuitively and accurately make decisions and operations.
For example, Hitachi Review, Vol. 78, 1998, 21st to 25th.
As shown in the page “Intelligent Central Power Supply System Achieving Advanced System Operation”, the routes of power system diagrams to be monitored, power plants, substations, etc. are arranged on a map, providing the operator with a geographical sense. It enables suitable monitoring and visualizes tracks, power plants, and substations with colors and patterns according to the voltage class and operating conditions, making it easier for operators to grasp macroscopically. Further, the display device described in Japanese Patent Application Laid-Open No. H10-187233 discloses a monitor that displays a display portion of each facility by spotlight display means when the facility becomes abnormal on a screen displaying each facility and its system. Make it immediately recognizable. Further, the display device described in Japanese Patent Application Laid-Open No. H11-95965 periodically collects each state from each component of the system, and converts one cell on the screen to the state of the component at a certain time from the collected data. The cell is displayed with the brightness corresponding to the association and the state of the component.

[0004]

With the increase in the scale of the power system monitoring and control system, various kinds and a large amount of information can be used from any place, but the information can be efficiently or effectively determined in the conventional GUI. And flooding of information will occur.

[0005] Therefore, there is a demand for a screen configuration which facilitates macroscopic grasping while efficiently concentrating a large amount of information. For example, the power system diagram is used in all graphic user interfaces such as a central power supply dispatching office and subordinate control offices, as well as business offices. When a user at an arbitrary substation receives and restores the system diagram data, it is often difficult to grasp the location of the fault or the spread only by displaying the jurisdiction of the own substation. For this reason, other jurisdictions can be displayed together, so that the display of jurisdiction ranges and non-jurisdiction ranges, the superimposition of online information, etc. can be efficiently concentrated, and the user can easily understand macroscopically. Providing a possible system diagram screen is an important issue for a power information GUI.

Further, today's GUIs are not simply display screens for displaying information, but are editing means for selecting and processing information, and are operating means replacing conventional control panels. It is a tool for control. For example, in the monitoring and control work, the operator performs a corresponding measure while making a determination through three processes of grasping the outline, grasping the main cause, and grasping the auxiliary cause. For this reason, the operator cab is equipped with three CRTs. In addition, a plurality of CRTs are used to display a substation monitoring screen showing the substation names of main substations and numerical values as monitoring information in a tabular form, specify a substation, and pop up a substation system diagram, A trend graph for one piece of information is displayed by designating a predetermined location in the system diagram.

FIG. 6 is a view showing an example of an electric station monitoring screen.
An example is shown in which items to be monitored and their current values and reference values are displayed for each facility at each electric substation. In such a screen display, when the system is large-scale and there are many monitoring items, the screen is scrolled or a plurality of display devices 22 are arranged in order to display them at a time. Since it is difficult to understand simply by displaying the numerical values in the list in the list format, the trend graph can be displayed on the pop-up screen by appropriately specifying the items as described above. The monitoring of the system itself is performed by a computer, and the operator grasps the state of execution by displaying the screen. Monitoring the screen requires a conscious approach, and the operator must constantly pay attention to where to look.

As described above, the conventional system monitoring GUI
Is to select information from macro information to macro information in detail, so that an operator is required to perform an operation for that. In addition, many screens are prepared for each application, and it is necessary for the operator to operate the screen display while paying attention to the operation of a wide range of general systems, and to display each monitoring item on each screen. You need to pay attention. The one disclosed in JP-A-11-95965 is
Although the overall tendency can be grasped by the light and darkness of the small cell, no consideration is given to the detailed monitoring situation.

As described above, since an excessive load is imposed on the operator during monitoring, the monitoring G is effective for reducing the load.
UI is required.

A first object of the present invention is to provide a graphic user interface for monitoring and a monitoring control method which are effective in reducing a load, without imposing an excessive burden on an operator during monitoring.

A second object of the present invention is to provide a graphic user interface and a monitoring control method capable of grasping the monitoring performance in more detail. A third object of the present invention is to provide a graphic user interface and a supervisory control method capable of grasping an outline of execution and more detailed contents.

Reference numeral 10 is a monitoring screen required for power system monitoring and operation work, which is configured by a screen in which an operation unit and an application area unit are integrated. The monitoring screen of this embodiment is roughly divided into a system diagram and a monitor screen. The system diagram is an application of a menu of “macro” or “detailed system diagram”, and the monitor screen is an application of a menu of “system monitor”. The monitor is also referred to as monitoring.

FIG. 3 shows a state in which the macro system diagram screen being displayed is marked, and shows a state in which color dyeing is being performed as an example of the marking. In the macro system diagram, as described above, electric stations and the like are displayed in a rough geographical arrangement, so not only system equipment but also weather information and customer equipment that have a significant effect on system operation are displayed together. ing. For this reason, it is convenient to comprehensively grasp the general situation of the system operation. The screen shown in FIG. 3 displays an overview of system monitoring superimposed on this macro system diagram. In the example of FIG. 3, the supply area C1 has been monitored, and the supply area C2 is being monitored. In addition, on the display screen, the lower voltage system of the supply area C2 is displayed in a pop-up manner, so that the monitoring status of the lower voltage system can be displayed. A character is simultaneously displayed in the voltage sub-system displayed in a pop-up manner. In this example, the expression indicates that there is no operational problem with the voltage sub-system currently monitored.

The display processing shown in FIG. 3 will be described with reference to the flow shown in FIG. When monitoring control is started in step 30, a macro system diagram is displayed in step 31. In step 32, it is determined whether or not the displayed macro system diagram is to be deleted. However, the macro system diagram being displayed is deleted when the screen itself is deleted or the screen is switched to another screen. In step 33, it is determined whether or not the displayed macro system diagram has been interrupted to change the specifications of the monitor such as color dyeing. The specification of the marking such as color dyeing can be set at any time according to the request of the operator. When the specification such as color dyeing is changed, the specification change such as color dyeing is performed in step 34. To explain the color dyeing, the specification items of the color dyeing include the speed of the color dyeing at each electric station, and in the case of an electric station requiring attention, perform the operation slowly or easily as shown in FIG. In addition to the higher voltage system that can display the entire system, the lower system is also displayed as appropriate in one screen. The color dyeing only presents the status of monitoring to the operator, or the target monitoring result is also taken into account as shown in FIG. For example, whether the characters are displayed in addition to the colors as the monitoring result display as shown in FIG.

In step 35, an electric station of interest is set, and in step 36, the electric station of interest is monitored to perform color dyeing and the like. In step 37, it is determined whether or not the lower voltage system also performs color tinting or the like. When performing the color tinting or the like, in step 38, the lower voltage system color tinting or the like is performed. The color dyeing is performed periodically, and in step 39, it is determined whether or not monitoring of all the electric stations of interest or all of the electric stations in the display system has been completed. In step 40, the color dyeing or the like is reset and started again. As a marking method, besides coloring, there is a method of moving a character or a symbol in a screen.
Also, the display order of each electric station can be set in advance including the rule.

As described above, the progress status of the monitor is displayed in the macro system diagram by coloring, etc., so that the operator can grasp the whole picture of the system operation and monitor the monitor without being bothered by operations such as screen switching. You can grasp the progress.
Further, since the voltage lower-order system is displayed on the macro system diagram and the monitoring status of the voltage lower-order system can be monitored by coloring or the like, the monitoring execution status can be grasped in more detail. Also, by displaying the character, the status of the system can be grasped from the expression. Further, since specifications such as color dyeing can be set according to the purpose and preference, versatile use of the display screen becomes possible.

Further, the pace of color dyeing or the like can be set slightly faster, for example, in a portion having no problem, and a portion of a problem requiring caution can be set a little slowly. To notify that the monitoring is being performed. Further, not only the monitoring is being performed but also the status of the target can be roughly grasped by color-coding or the like according to the status of the target to be monitored.

Another embodiment of the present invention will be described with reference to FIG. FIG. 5 shows an example of a monitoring screen which is a system monitor but is different from the monitoring screen shown in FIG. The screen shown in FIG. 5 is roughly divided into three parts, and the respective partial systems and the associated electric stations are hierarchically displayed on the left part of the screen. In this display, the folder of the partial system is displayed in the system being monitored (also referred to as monitoring) so that it is possible to know which part of the entire system is being processed in order to make use of the limited space. The system that has been monitored (also referred to as "monitored") and some of the systems that have not been started are displayed. The monitored electrical system and the electrical station of the monitored system may be identified by changing color dyeing or the like.

Each monitor item of the electric station being monitored is displayed in the lower right part of the screen, and each trend graph is displayed in the upper right part of the screen above this display part. Since the screen shown in FIG. 5 displays more detailed contents than the screen shown in FIG. 3, on the right side of the screen, only the items of the operation important electric stations and the items requiring special attention are displayed. are doing. The arrangement of the sub-systems and the electric stations displayed on the left side of the screen can be designated in advance.

As described above, in this embodiment, the screen is divided and the monitored system, the electric stations of the system being monitored, the monitoring items, and the trend graph are displayed on one screen. Content can be understood.

Normally, a plurality of display devices are used for monitoring. By arranging the display screen shown in FIG. 3 and the display screen shown in FIG. 5 and synchronizing the processing such as color dyeing with each other, the display screen shown in FIG. The details of the execution can be understood by looking at the screen shown in FIG. 5 by looking at the outline of the execution on the screen shown in FIG. Note that even when a plurality of screens are arranged, it is possible to view the monitoring progress while switching the display of one screen, and to view the monitoring progress while switching the display even on one screen. In this case, since a plurality of screens need not be arranged for monitoring, there are advantages such as a reduced number of display devices.

In the above description, the GUI is one CRT
Although the description has been given of the case where the terminal is realized by the terminal 10 having the above, the present invention is also applicable to a screen such as a large screen or a console including a plurality of CRTs.
