Description

  The present invention relates to a power system diagram information generating system for generating power system diagram information indicating a power system diagram, a power system diagram information generating method for the power system diagram information generating system, and the power system diagram information generating system to the power system diagram information generating system. The present invention relates to a program for executing a generation method.

  In general, a power system diagram is a diagram representing a network of symbols that symbolizes components of a power system such as a generator, a load, a bus, a power transmission line, a circuit breaker, and a disconnector. The power system diagram information indicating the power system diagram is generated based on power supply information from a monitoring control device that monitors the power system, and is transmitted to, for example, a terminal of an employee of an electric power company that has jurisdiction over the power system. For example, every time the state of the power system changes, the power system diagram information generating device that generates power system diagram information receives the state change information from the monitoring control device and reflects it in the power system diagram (for example, Patent Document 1). reference.). Here, the power system diagram information generation device is installed at, for example, a central power supply command station that performs overall control and supply / demand operation of the power system, and the monitoring and control device operates, for example, for individual power plants. It is installed at a control station where monitoring is performed.

  In recent years, with the partial liberalization of electric power, for example, customers have defined the electric power generated by a specified scale electric power company (hereinafter referred to as “PPS”) as defined by the Electricity Business Law. It can be purchased through a transmission line, etc., under the jurisdiction of a power company that is a general electric company. Therefore, the PPS generator or the like is incorporated as a component in the power system described above. Since this power system diagram information includes not only the power company but also information related to PPS, the scope of disclosure is limited according to the disclosure destination by the Electricity Business Law. In general, a department that performs a series of operations related to power supply related to PPS is called a consignment department. For employees belonging to this consignment department, information on all components of the power system can be disclosed, while for employees belonging to non-consignment departments, the components related to PPS corresponding to the department Disclosure of information is prohibited. The act of prohibiting the disclosure of this information is called information blocking. For example, even in the consignment department and non-consignment department in the electric power company, some information is shared between departments to take accountability to the outside. For other certain information, it is obliged to block information between departments.

When the power system diagram information generation apparatus described above performs information blocking, power system diagram information that does not include information such as predetermined PPS (information blocked) is generated for each of a plurality of departments. When the power system diagram information generating device and the terminal of each department are connected to be communicable via, for example, an intranet within an electric power company, the power system diagram information generating device is shut off according to a request signal from the terminal. Power system diagram information is generated and returned to the terminal. In this case, for example, the power system diagram information generation device generates in advance a plurality of power system diagram information not including information such as predetermined PPS for each of a plurality of departments, and responds to the request signal. Select from and reply.

  However, in order to implement the information blocking described above, the power system diagram information generation device must generate power system diagram information for the number of departments in advance and store it in a predetermined database (storage unit). . Therefore, as the number of departments increases, the occupation ratio of the power system diagram information with respect to the capacity of the database increases, so the load on the database increases. This forces an expansion of the capacity of the database, and as a result, there is a risk of increasing the equipment cost.

  In addition, if there is a change in the department where the information block is implemented or the contents of this information block, each time this change is made, new power system diagram information for the number of departments must be generated and the aforementioned database must be updated. Don't be. This imposes a burden on, for example, an operator who manages the power system diagram information generation device, and may result in an increase in maintenance costs.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a power system diagram information generation system that can easily generate power system diagram information without placing a burden on the storage unit. is there.

  The invention for solving the above-mentioned problems includes: a first storage unit that stores power system diagram information in which all components of the power system are indicated by symbols; and a symbol that indicates all components of the power system. A second storage unit that stores mask information for masking specific symbols indicating some components of the power system, and reading from the first storage unit in response to a request signal for masking the specific symbols And a combination generation unit that combines the generated power system diagram information and the mask information read from the second storage unit to generate the power system diagram information masked with the specific symbol.

  According to this power system diagram information generation system, the composite generation unit can read different mask information from the second storage unit so as to mask different specific symbols according to the request signal, for example. Further, the combination generation unit combines each of the different mask information with, for example, one power system diagram information stored in advance in the first storage unit, and different specific symbols are masked according to the request signal. Different power system diagram information can be used. Since this mask information corresponds to only specific symbols, it can be easily changed, for example, compared to power system diagram information having symbols indicating all components of the power system. Therefore, for example, in the case of the power system diagram information generation system of the present invention, the first power system diagram information generation system of the present invention is compared with the case where a plurality of power system diagram information is generated and stored in advance for each of a plurality of assumed request signals. The load on the storage unit and the second storage unit is small. That is, for example, one power system diagram information stored in the first storage unit and a plurality of mask information stored in the second storage unit, for example, can be smaller in data size than a plurality of power system diagram information. .

  In addition, when the plurality of power system diagram information described above is generated and stored in advance, for example, every time a plurality of assumed request signals themselves are changed, all of the plurality of power system diagram information must be regenerated. I must. On the other hand, according to the power system diagram information generating system of the present invention, for example, only mask information may be changed. This is equivalent to the fact that power system diagram information can be generated relatively easily.

  As described above, a power system diagram information generation system that can easily generate power system diagram information without imposing a burden on the storage unit is provided.

  In the power system diagram information generation system, the second storage unit stores a plurality of mask information for masking a plurality of specific symbols indicating some components of the power system, and the combination generation unit In response to the request signal, by superimposing the power system diagram information read from the first storage unit and a plurality of mask information selectively read from the second storage unit, It is preferable that power system diagram information masking the specific symbols is generated.

  According to this power system diagram information generation system, for example, a plurality of specific symbols in one power system diagram information are selectively read out from a plurality of mask information stored in advance in the second storage unit. This mask information can be used for masking. Accordingly, different combinations of the plurality of specific symbols corresponding to different request signals may be made to correspond to different selection methods. This makes it easier to mask specific symbols and further reduces the load on the second storage unit.

  In the power system diagram information generation system, the second storage unit stores a plurality of mask information for masking a plurality of specific symbols indicating some components of the power system, and the combination generation unit In response to the request signal, a single mask information is generated from a plurality of mask information selectively read from the second storage unit, and is read from the first storage unit. It is preferable that power system diagram information in which the specific symbol is masked is generated by superimposing the information and the single mask information.

  According to this power system diagram information generation system, for example, for a combination of a plurality of specific symbols in one power system diagram information, a combination is selected from a plurality of mask information stored in advance in the second storage unit. Masking can be performed with the obtained single mask information. Accordingly, different combinations of the plurality of specific symbols corresponding to different request signals may be made to correspond to different selection methods. This makes it easier to mask specific symbols and further reduces the load on the second storage unit. Also, once this single mask information is generated, for example, when the same request signal is received subsequently, the above selection and combination operations can be omitted for the second and subsequent request signals. The power system diagram information can be generated more quickly with respect to the request signal.

In addition, the power system diagram information generation system includes a request signal generation unit that generates the request signal, and a display unit that displays the power system diagram information generated by the composite generation unit in response to the request signal. A terminal may be further provided.

You can browse the power system diagram information.

In the power system diagram information generation system, the first storage unit, the second storage unit, and the combination generation unit may be provided outside the terminal.
According to this power system diagram information generation system, since the terminal does not need to have, for example, a memory, a program, a module, or the like corresponding to the first storage unit, the second storage unit, and the synthesis generation unit, its equipment cost Can be saved. If the request signal generator of the terminal generates a request signal specific to the employee who uses the terminal, for example, the power system diagram information specific to the employee is generated outside the terminal. Is done. Therefore, since the display unit of the terminal only needs to have a function of displaying the generated power system diagram information, it is not necessary to have a different function for each terminal, and the equipment cost can be further reduced.

In the power system diagram information generation system, the terminal may include the second storage unit and the combination generation unit.
According to this power system diagram information generation system, since the terminal has the second storage unit and the composite generation unit, for example, only one power system diagram information needs to be transmitted to this terminal. Thereby, since the data transfer amount with respect to the communication line between a terminal and the 1st memory | storage part can be reduced, the installation cost can be saved more.

A mask information generator for generating mask information for masking the specific symbol in response to a request signal for masking a specific symbol indicating a part of the component, and reading from the storage unit in response to the request signal And a combination generation unit that combines the output power system diagram information and the mask information to generate power system diagram information in which the specific symbol is masked.

  According to this power system diagram information generation system, the mask information generation unit can generate different mask information so as to mask different specific symbols according to the request signal, for example. In addition, the synthesis generation unit combines each of the different mask information with, for example, one power system diagram information stored in advance in the storage unit, and different power systems in which different specific symbols are masked according to the request signal, respectively. Graphic information can be generated. Since this mask information corresponds to only specific symbols, it can be easily changed, for example, compared to power system diagram information having symbols indicating all components of the power system. Therefore, for example, in the case of the power system diagram information generation system of the present invention, compared to the case where a plurality of power system diagram information is generated and stored in advance for each of a plurality of assumed request signals, the storage unit The load against is small. That is, for example, one power system diagram information stored in the storage unit is smaller in data size than a plurality of power system diagram information.

  In addition, when the plurality of power system diagram information described above is generated and stored in advance, for example, every time a plurality of assumed request signals themselves are changed, all of the plurality of power system diagram information must be regenerated. I must. On the other hand, according to the power system diagram information generating system of the present invention, for example, only mask information may be changed. This is equivalent to the fact that power system diagram information can be generated relatively easily.

  As described above, a power system diagram information generation system that can easily generate power system diagram information without imposing a burden on the storage unit is provided.

  On the other hand, when it is determined that the power supply information is received from the monitoring control device 200 (S100: YES), the power system diagram information generating device 100 updates the power system diagram information database 131 based on the received power supply information (S101). ) Based on the updated power system diagram information database 131, new power system basic image data 134a is generated (see FIG. 5), and the basic image database 134 is updated (S102).

  Next, power system diagram information generation apparatus 100 (specifically, WWW server 150 therein) determines whether or not a request signal for requesting a power system diagram has been received from OA terminal 300 ( S103). This request signal is generated based on the browser program stored in the memory of the OA terminal 300 described above. In this browser program, for example, a browser program (for example, a WWW browser) for browsing a Web page generally used on the Internet is applied to the intranet 30 of the present embodiment. This browser program is configured such that, for example, when an update button on a menu screen displayed on the display 300b is clicked, the OA terminal 300 transmits a request signal. In addition, the operating system stored in the above-described memory of the OA terminal 300 is the browser program described above when an employee in a certain department A (FIG. 1) logs in the OA terminal 300 by putting his / her IC card over the card reader 300c. Is configured to start automatically, for example. Here, the request signal described above includes, for example, URL information indicating the WWW server 150 in the intranet 30, IP address information of the OA terminal 300, and ID information read by the card reader 300c of the OA terminal 300. It is a waste.

  If it is determined that the request signal has not been received from the OA terminal 300 (S103: NO), the power system diagram information generating apparatus 100 (specifically, the image data conversion server 120 therein) performs the above-described steps. The process of S100 is performed again.

  On the other hand, when it is determined that a request signal has been received from the OA terminal 300 (S103: YES), the power system diagram information generation device 100 (specifically, the WWW server 150 therein) refers to the ID information database 141. Then, information indicating the department to which the employee corresponding to the ID information included in the request signal belongs is acquired (S104).

  Next, the power system diagram information generation device 100 (specifically, the image data conversion server 120 therein) is prohibited from disclosing to the department identified in step S104 with reference to the cutoff information database 132. Information indicating a component (for example, a predetermined PPS generator) is acquired. In addition, the power system diagram information generation device 100 refers to the mask pattern information database 133 and acquires mask pattern information associated with information indicating the above components and information on the coordinates thereof. Furthermore, the power system diagram information generation device 100 acquires mask pattern image data 135a, 135b, and 135c corresponding to the mask pattern information from the mask pattern image database 135. Here, when there are a plurality of the constituent elements for the specified department, a plurality of mask pattern image data 135a, 135b, and 135c are acquired. The power system diagram information generation device 100 considers the coordinate information as a position with respect to the outline of the basic image data 134a, arranges mask pattern image data 135a, 135b, and 135c, and mask layer image data (for example, mask layer image data). Data 136b) (see FIG. 5) is generated and stored in the work database 136 (S105). The generation of the mask layer image data 136b is performed based on the above-described well-known drawing program.

In addition, the corresponding department image data (for example, department A image data 136d) is generated (see FIG. 5) and stored in the work database 136 (S106). The superposition is performed based on the above-described well-known drawing program.

  Next, the power system diagram information generation apparatus 100 (specifically, the WWW server 150 in this) corresponds to the corresponding department stored in the work database 136 for the IP address information of the OA terminal 300 included in the request signal. Image data (for example, image data for department A 136d) is transmitted. At this time, on the menu screen where the above-mentioned update button on the display 300b is clicked in the OA terminal 300, a power system diagram in which a predetermined component is not visible is displayed (S107).

  As illustrated in FIG. 5, in the basic image data 134a, all components of the power system are indicated by symbols. For example, an employee of department A of an electric power company inputs his / her IC card to the card reader 300c, logs in to the OA terminal 300, starts a browser program, and clicks an update button on the menu screen displayed on the display 300b. To do. At this time, a mask layer image 136b for masking the generator of the PPS generator whose disclosure to the department A is prohibited (for example, the center of the basic image data 134a in FIG. 5) is generated and superimposed on the basic image data 134a. Then, the department A image data 136d in which the corresponding generator is masked (hidden) is generated. On the other hand, in the case of an employee of department B of an electric power company, a mask layer image 136c that masks a generator of a PPS generator whose disclosure to department B is prohibited (for example, the right side of basic image data 134a in FIG. 5). The department B image data 136e is generated and superimposed on the basic image data 134a to mask the corresponding generator.

  In the present embodiment, one mask layer image data 136b is generated by combining a plurality of mask pattern image data 135a, 135b, and 135c, but is not limited to this. For example, there may be a plurality of sets of one mask layer image data composed of one mask pattern image data, and the plurality of sets may be regarded as one mask layer image data.

  In this embodiment, the mask layer image data 136b is generated every time a request signal is received and stored in the work database 136. However, the present invention is not limited to this. For example, mask layer image data for the number of departments may be generated in advance and stored in, for example, the mask pattern image database 135 or the like.
