Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supervisory control method and system thereof, and more particularly to a supervisory control method and system thereof suitable for improving usability when supervisory control means having a new function is added.

[0002]

2. Description of the Related Art The role of a supervisory control system is to perform control for acquiring data of a subject to be monitored and maintaining or correcting the subject to be monitored in an appropriate state. The relationship between the operator and the supervisory control system is to present the data obtained from the monitoring target as it is from the perspective of the supervisory control system or to present it in a form that is easy for the operator to use. Is to give a command to control the object to be monitored and to switch the function of the monitoring control system. Generally, a supervisory control system is composed of a plurality of supervisory control means such as a data collection device on a power system, a data recording device, and a numerical calculation program for calculating a signal for system control.

In the conventional supervisory control system, how to use the supervisory control means for supervisory control work and how to operate it are fixed within the range designed at the time of constructing the supervisory control system. The functions of multiple monitoring control means can be combined according to the work of the operator up to the combination range considered when designing the monitoring control system. For flexible operation of the monitoring system other than that combination, The operator must process the system monitoring work while considering the processing result of each monitoring control means. In addition, when a new monitoring control means is added to the monitoring control system, in order to effectively use the new function in combination with the conventional function, a major modification of the entire monitoring control system including the man-machine interface is required. is there.

For example, assume that the monitoring target is a power system and the operation purpose is to display the power flow of a certain facility in the power system. In this case, the function selection of the power flow display and the instruction of the equipment are made through the man-machine interface, and the screen showing the power flow is displayed. The display content may be, for example, to display the numerical values currently collected by the system data collection device, which is one of the monitoring control means. Depending on the operation of the operator, there is also a function to display the change in the power flow from today's morning to the present in a graph, and a function to display the change in the power flow based on the future power supply schedule and demand forecast. Conceivable.

For such a display, it is necessary to link with another monitoring control means such as a database that retains the history of electric power flow, a demand forecasting system, a database system of a grid operation plan, or the like. How to operate these multiple supervisory control means and how to display the data obtained from these means was fixed at the time of the initial design of the supervisory control system, and new functions should not be added. Have difficulty.

As a conventional technique for solving these problems, there is a technique of automatically changing the display contents of the display screen when a new monitoring function is added to the monitoring system. For example, in Japanese Patent Laid-Open No. 4-275025, when a new monitoring means is added, the source code of the display software held by the new monitoring means is transmitted to the display device via the LAN to update the display content.

[0007]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The prior art described in Japanese Patent Publication No. 25 is a configuration that does not stop the display of monitoring even when adding new monitoring means, and merely adds the display screen of the new monitoring means when adding new monitoring control means. Absent. Therefore, this conventional technique is merely a change for adding a new display screen, and it is not possible to extend the conventional display function by combining the added new function and the existing function.

In the current supervisory control system, the method of operating the functions of the supervisory control means is predetermined, and the operator devises various functions in order to flexibly process the supervisory work for controlling the variously changing objects. You have to use it. Further, even if a new monitoring control means is added, it is difficult to operate in cooperation with the existing monitoring control means, and in order to realize this, a large-scale modification of the entire monitoring control system is required. Moreover, since the supervisory control work is generally executed by a plurality of operators, it is necessary to coordinate the work among the operators. However, in the conventional supervisory control system, it is difficult to coordinate the work from the console assigned to the operator, and the work is coordinated by the large display panel where all the operators can confirm the whole information at the same time.

An object of the present invention is to provide a supervisory control method and a system thereof in which each operator can flexibly utilize the supervisory control function with respect to additional changes of supervisory control means.

[0010]

The above object is to provide one or more supervisory control means in a supervisory control system,
An input / output device for inputting information display to an operator and an operation instruction to the operator's supervisory control system, and a monitor control means corresponding to the operation instruction in the supervisory control system issued from the input / output device or the supervisory control means. To the input / output device, the monitoring control means, and a communication path for transmitting data and operation instructions between the operation analysis device, and the operation instruction of the operator and the data of the monitoring control means automatically. And a means for distributing to a suitable monitor control means.

[0011]

An operation analysis device for converting an operation instruction in the monitoring control system issued from the input / output device or the monitoring control means into an instruction to the corresponding monitoring control means is provided, and each monitoring control is performed based on the instruction of the operation analysis device. Since the means operates, even if the supervisory control means having a new function is added, if the operation analysis device knows the function of the supervisory control means, the operator knows the function of the newly added supervisory control means. Even without it, the function can be realized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a supervisory control system according to an embodiment of the present invention. The monitoring control system 100 of this embodiment
Is a large display device 101 and a plurality of small display devices 102, 10.
3,104 and input / output device 111,1 provided for each display device
12, 113, 114, and a plurality of monitoring control means 121, 122, 123 and an operation analysis device 130 which are connected to each input / output device via a communication path 140.

The input / output devices 111-114 display information relating to the controlled object and information relating to the supervisory control system on the display devices 101-1.
Display on screen 04. When an operator operates the touch panel or keyboard (not shown) of the display devices 101 to 104 to input system operation information and control commands, the input data is input to the input / output devices 111 to 114 through the communication path 140. It is notified to the monitoring control means 121 to 123 and the operation analysis device 130 via the.

The supervisory control means 121-123 have a data processing function for supervisory control, and control objects and input / output devices 111-11
4. Control target data, system operation information, and control commands obtained from the operation analysis device 130 through the communication path 140 are processed according to the purpose of monitoring control.

The operation analysis device 130, as shown in FIG.
The database control means 201 is provided, and this control means 201 is
Function item database 211 and operation analysis database 212
Then, the operation state database 213 is operated. In the function item database 211, the correspondence between the monitoring control means 121 to 123 and the functions they have is registered as the function items to be registered. The operation analysis database 212 includes each input / output device 111-
114 or the system operation information or control command issued by each of the monitoring control means 121 to 123 and the association with the function item are registered.
In the operation status database 213, the distribution of operation instructions between the currently used input / output device and the monitoring control means is registered.

The database control means 201 refers to the function item database 211 and the operation analysis database 212, selects a monitor control means corresponding to the purpose of monitor control, and distributes system operation information and control commands to the monitor control means. or,
If you add a monitoring control unit with a new function, update the function of an existing monitoring control unit, or stop the function of the monitoring control unit, update the registered contents of the database accordingly. Then, even if the configuration of the supervisory control system is changed, the system operation information is appropriately distributed to the supervisory control means. For example, when adding new monitoring control means to the monitoring control system, the relationship between this new monitoring control means and its function items is registered in the function item database 211.

FIG. 3 is a block diagram of a supervisory control system for monitoring the electric power system. Although the basic configuration is the same as that of FIG.
121, a display control device 122, a prediction device 123, and a system state calculation device 124.

The data collection device 121 acquires equipment data such as voltage and power flow from a plurality of slave station devices 151, 152, 153 monitoring equipment on the power system via the master station device 150, The equipment is provided with necessary equipment data in response to the requirements of other equipment in the supervisory control system.

The display control device 122 outputs information necessary for constructing a man-machine interface to the input / output devices 111-114.
Send to The information here is setting information indicating in what format data about the power system is displayed. The data display format is now called a dialog box or a figure.
It can be controlled in the form of types. The large display device 101 displays the entire current facility data of the power system to be displayed. To achieve this easily, the large display 10
It suffices for 1 to instruct via the input / output device 111 to deliver the data necessary for displaying the data of the entire facility data from the data collection device 121. The flow of instructions and data between the devices at this time is as shown in FIG. The vertical line represents the time axis, and the left and right arrows represent the instruction or data flow between the devices. In this case, the desired data display can be realized simply by instructing the data transfer between the two devices. That is, when the data display of the facilities 1 and 3 is designated, the input / output device 111 instructs the data collecting device 121 to transfer the data 1 and 3, and when the data 1 is transferred from the data collecting device 121, the input / output device is input. 111 displays the data 1 and displays the data 2 when the data 2 is transferred. However, if various data display controls are performed using other multiple monitoring control means, the flow of instructions and data of each device becomes complicated, and unless some measures are taken, maintenance and functions of the control system are performed. Expansion becomes difficult. However, in the present embodiment, since the operation analysis device 130 is provided and the function of each monitoring control unit that constitutes the monitoring control system is registered here,
It is possible to analyze which supervisory control means is required for the target processing, which facilitates maintenance and function expansion of the control system.

Hereinafter, the display device 102 used by the operator
When displaying the system diagram as shown in Fig. 4, the operation analyzer
Explain how the 130 works. FIG. 8 is a diagram showing a flow of instructions and data between the devices at this time.

When the operator wants to display the current data of a certain facility, for example, the power flow in a dialog, the operator designates the facility of the data representation format and the system diagram with a mouse or a light pen. In the example shown in FIG. 4, there are choices of "dialog" and "graphic display" as data display formats. Regarding the operation of displaying the data of the facility, the operation instruction “display the current data of the transformer on the display device 102” is transmitted to the communication path 140 by the input / output device 112.

The operation analysis device 130 analyzes this operation instruction. The analysis is performed by searching the corresponding function item using the operation instruction as a keyword. For example, a database of operation instructions and function items as shown in FIG. 9 is searched. If you add monitoring control means with new function items,
By updating this database and using the updated database, the operation analysis device can know the addition of a new function.

The database control means of the operation analysis device 130 of FIG. 8 makes an inquiry to the operation analysis database 212 of FIG. 9A, and the operation instruction may correspond to the dialog display format setting of the function item and the data transfer. Then, the function item database 211 of FIG. 9B is inquired, and it is known that the dialog display format setting is the function item of the display control device and the data transfer is the function item of the data collection device 121. Then, the operation analysis device 130 sends the current data of the transformer to the data collection device 121 by the input / output device 1.
The display control device 122 is instructed to deliver the data, and the display control device 122 is instructed to send a data display instruction in the form of a dialog box to the input / output device 112. Further operational analyzer 130
Causes the data collection device 121 to transfer the data to the input / output device 112 and to register in the operation state database 213 the current operation state that the data display format setting instructed by the display control device 112 is being used.

By the above operation, the input / output device 112 is
Data is displayed on the display device 102, for example, in a dialog format as shown in FIG. If the data collection device has not collected the data of the facility to be displayed, the data analysis device sends a message indicating that data has not been collected to the operation analysis device, and the operation analysis device sends a message that cannot be displayed to the input / output device.

Since the data transfer instruction and the data display format setting are independent, if the data display format is specially set when the data display operation is instructed, the same data is displayed by the display control device 112 as required by the operator. It can be displayed in various formats using the format set in. On the display device 103 shown in the lower part of FIG. 5, the power flow value is displayed in the size of the arrow on the system diagram. This is "graphical display" as the display format
This is because is selected.

When the setting of the display control device 122 is changed and the format for displaying the facility data in a graphic form cannot be used, the data format setting instructed by the operation analysis device 130 is changed to the dialog format. By doing so, the data display function can be supplemented. At this time, the operation status database in the operation analysis device is also updated to enable appropriate distribution of operation instructions.

Next, the mechanism by which the function is automatically reflected in the supervisory control system when a new supervisory control means is added will be described. The prediction device 123 illustrated in FIG. 3 is a device that predicts the future system state based on the data recorded in the system operation database 161. The system operation database 161 may be internal to the supervisory control system, but here it is assumed to be external as it is not referenced by other supervisory control means. The system status calculator 124 is
It is a device for calculating an error of equipment where data is not observed or an error of observed data based on data of a system obtained from the data collecting device or data obtained from other monitoring control means.

Now, the prediction device 123 and the system state calculation device 1
Suppose 24 was added to the supervisory control system. By this addition, new information is registered in the database in the operation analysis device 130. As a function of the prediction device 123, transfer of facility data at a predictable time is registered in the function item database. Further, as a function of the system state calculation device, transfer of all facility data that can be calculated is similarly registered. By updating these function item databases, the contents of the operation analysis database are also updated, and it becomes possible to transfer equipment data at consecutive points in time.

As a result, the graph format is added to the setting of the data format that can be displayed by the input / output device. By this addition, as shown in FIG. 6, a "graph" is added in the display format menu. Here, when the “graph” is selected and the operation instruction to display the power flow as the data of the transformer in the graph format is issued from the input / output device 114, the operation analysis device refers to the database by the operation analysis device. Analyze and distribute operating instructions to appropriate monitoring and control means. Then, the display control device is instructed to send the graph display format setting to the input / output device 114. In addition, the system state calculation device 124
Includes the data input / output device for the time required to display the data.
Instruct to send to 4. Furthermore, the prediction device 123 is instructed to send data at an arbitrary time required by the system state calculation device 124. As a result, future time data is predicted, and past data is obtained from the grid operation database. By the cooperation of the plurality of monitoring control means as described above, it becomes possible to display a graph of data as shown in FIG.

When a monitoring control means is newly added in this monitoring control system, a new function is additionally displayed on the menu as shown in FIG. 6, but it is assumed that the operator may overlook the addition of the new function only with this display. To be done. Therefore, in this embodiment, when the operator gives an instruction to display the system expansion message, as shown in FIG. 10, it is possible to easily know the addition of the function by the addition of the monitoring control means, and the additional function is immediately used. It becomes possible.

[0031]

According to the present invention, there is an advantage that the operator does not need to be familiar with the supervisory control means inside the supervisory control system in order to execute the supervisory control work. In other words, the operation instruction to display the equipment data is analyzed by the operation analysis device and distributed to the appropriate monitoring control means, so that even if the monitoring control means is changed or added, the operator needs to be aware of the change. Absent.

Further, according to the present invention, the function update of the supervisory control system can be automatically reflected in other supervisory control means or input / output device. For example, by adding a prediction device, the availability of the new display format can be automatically changed to the operation screen. Further, the operation analysis device instructs the system condition calculation device to retrieve the facility data at any time from the prediction device. This is because the database of the operation analysis device has a relationship between the operation instruction and the monitoring control means. This is possible by placing the concept of function items in the middle, rather than registering.
