Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention divides a system to be processed by a system such as a real-time computer system for monitoring and control of a power system into a plurality of system diagram screens, and expresses connection of system elements of the target system as network data of nodes and branches. The present invention relates to a method for automatically generating network data in a system to be used by utilizing.
[0002]
[Prior art]
A node in this type of network data is a network element having an unspecified number of connection points, and a branch is a network element located between nodes and having two connection points and connecting between nodes.
[0003]
In an electric power system, a bus and other electric circuits correspond to nodes, and a switch connecting electric circuits corresponds to a branch. Note that, depending on the use of data, the bus may be a node, and an electric circuit that cannot have three or more connection points may be one branch including a switch.
[0004]
The data expression of the network by the node and the branch is a data expression in a link data format for setting a branch connected to the node, a node connected to the branch, or both.
[0005]
In such a system in which the network to be monitored and controlled is constituted by one system diagram screen, there is a system which realizes an automatic generation method from the screen data, as shown in FIG. In a system configured with a plurality of system diagram screens, there are overlapping portions of system elements between screen data. In the figure, the screen blocks A to D are separated by broken lines, the intersections of the blocks are the overlapping portions of the screen, and the system elements of this overlapping portion exist in a plurality of screens.
[0006]
This overlapping portion is provided for the reason that a human can easily recognize the connection relationship between the system elements and other screens.For example, when the power system is to be monitored and controlled, the substation and the substation must be connected. The screen that displays the grids to be connected shall be a screen that partially includes the system elements of the substations at both ends.
[0007]
Screens including such overlapping parts of system elements do not have an effective method for automatically generating correct network data by extracting inconsistencies between screens due to erroneous input of data. Network data is created manually according to the data expression.
[0008]
[Problems to be solved by the invention]
In a system composed of a plurality of system diagram screens, data conforming to the data representation of nodes / branches is manually created and input. However, great effort is required for data creation and error extraction.
[0009]
In particular, in the automatic generation of network data from a plurality of screen data, it takes time to detect inconsistencies between screens due to erroneous input of screen data in overlapping portions between the plurality of screens.
[0010]
An object of the present invention is to provide a method that can automatically generate network data even when there are nodes / branches overlapping between a plurality of screens.
[0011]
[Means for Solving the Problems]
The present invention automatically generates network data by performing an erroneous data input check, a branch registration / node registration presence / absence check, and a node / branch connection condition inconsistency check for each screen data having an overlapping portion. It is characterized by the following method.
[0012]
In the system to be processed by the computer system is divided into a plurality of system diagram screens having overlapping portions with each other, and the connection of the system elements of the target system is created as network data of nodes and branches.
First check means for checking a data erroneous input with respect to each screen data having a system element serving as the node and the branch, its identification information, and connection information between the system elements;
For each screen data for which no erroneous input has been eliminated by the first check means, the presence or absence of system element branch registration and node registration is checked, and a new one is registered as a new registered branch or node. Means,
A third check unit that checks the screen data including the new registered branch and the node for inconsistency in the connection condition of the branch or the node with respect to the node or the branch,
Unless inconsistency between the divided screens is detected by each of the check means, it is generated as correct network data.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
The present embodiment will be described with reference to automatic generation of network data of a power system, but can also be applied to systems such as gas and water.
[0014]
In the automatic generation of network data of the power system, screen data to be input represents an electric circuit or a switch connecting the electric circuit, identification information of the electric circuit or the switch (hereinafter referred to as ID), and presence or absence of connection of the electric circuit switch. Information (coordinates on the screen, etc.). Note that devices such as a transformer are also included in the power system, but are omitted for simplification of description.
[0015]
Each screen representing a network includes mutually overlapping system elements, which are divided into a plurality of screens, for the purpose of representing connections between systems, and the like.
[0016]
Note that, as described above, the overlapping system elements originally include the substations on both ends of the screen that displays the system connecting the substations, and that the connection relationship with other screens for humans is included. Are inevitably provided because they can be easily recognized.
[0017]
In the present embodiment, in order to automatically generate network data, screen data is input, and data is output in accordance with the data representation of nodes and branches, including the connection of the system between a plurality of screens. To achieve this, the following data shall be included.
[0018]
(A) Data indicating a screen of a node and a branch that have already been registered.
[0019]
(B) Data indicating all the screens to be processed this time.
[0020]
(C) Data indicating a processed screen of the current processing target screen.
[0021]
(D) Data indicating the correspondence between the switch already registered as a branch and the branch.
[0022]
(E) Data indicating the correspondence between a node and a circuit already registered as a node.
[0023]
In the network data automatic generation method according to this embodiment, a computer is provided with a software configuration of a processing procedure shown in FIG. Each processing procedure individually performs the following processing for each divided processing target screen.
[0024]
(Step S1) Check for erroneous data input Verify that there is no basic erroneous data input below. This guarantees the validity of the subsequent processing.
[0025]
● Three or more electric circuits are connected to the switch, which is a system element.
[0026]
● The same switch is duplicated on the same processing target screen.
[0027]
(Step S2) Existence Check of Branch Registration Whether or not the switch connected to each electric circuit is already registered as a branch is checked by referring to the existing switch data. A switch registered in a branch is registered by having data associated with the branch.
[0028]
If the switch is not registered in the branch, the switch is separately registered as a new branch.
[0029]
This step S2 may be performed in the reverse order of the next step S3.
[0030]
(Step S3) Existence Check of Node Registration Whether or not each electric circuit is already registered as a node is checked with reference to existing electric circuit data. The electric circuit registered in the node is registered as having an association data with the node.
[0031]
If the circuit is not registered as a node, it is registered as a new node separately.
[0032]
(Step S4) Inconsistency Check of Separated Branches For each of the electric circuits registered in the node, the branch corresponding to the switch connected thereto and the connection branch of the node corresponding to the electric circuit are referred to the existing node branch data. To compare.
[0033]
In this comparison, if there is a branch that is missing this time and the branch is connected to another node in this screen, the switch and the electric circuit are assumed on the assumption that three or more nodes cannot be connected to the branch. Detects the possibility that the connection relation of the screen conflicts with other screens. In addition, the following conditions determine contradiction.
[0034]
● The node and the branch exist on another screen at the same time, and the screen is not on another screen to be processed or is a processed screen. If this condition is not satisfied, it can be determined that the connection has been changed, not a contradiction.
[0035]
(Step S5) Exceeding check of connection node Among the switches registered in the branch among the switches, the node corresponding to the electric circuit connected thereto and the connection node of the branch corresponding to the switch refer to the existing node branch data. And compare.
[0036]
In this comparison, if there is an inconsistent connection node in the existing data, the possibility that the connection relation between the switch and the electric circuit is inconsistent with another screen is detected on the premise that three or more nodes cannot connect to the branch. In addition, the following conditions determine contradiction.
[0037]
● The existing node exists on another screen, and the screen is not on another processing target screen or is a processed screen. If this condition is not satisfied, it can be determined that the connection has been changed, not a contradiction.
[0038]
(Step S6) Registration process of new branch and new node If no inconsistency between screens is detected in the above procedure, register / generate node / branch data including new nodes and branches as correct network data. .
[0039]
【The invention's effect】
As described above, according to the present invention, for each screen data, erroneous data input check, branch registration / node registration presence / absence check, and node / branch connection condition inconsistency check are performed, and thereby network data is Since automatic generation of node branch data from multiple screen data was previously prevented because of automatic generation, inconsistency detection between screens due to incorrect input of screen data at the overlapping part of system elements between multiple screens is automatically performed. It is possible to reduce human labor involved in data creation / verification, and eventually, development costs and system operation costs.
