Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In an embodiment, as shown in fig. 1, a power database model building method is provided, which is exemplified by applying the method to a power system server, and it is understood that the method may also be applied to a power system terminal, and may also be applied to a system including a terminal and a server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes the steps of:
step S101, a power system server acquires a plurality of power data collected by a plurality of power service systems and data fields of the plurality of power data.
The power data is data collected by the power service system, and may be a working voltage or a model of a transformer used by a certain power service system, an acquisition cost of the transformer, and the like, and the data field of the power data is a data field of the power data stored in the power service system. For example: the power service system stores the operating voltage of the transformer a as a1, the model as a2 and the purchase cost as a3, the operating voltage of the transformer B as B1, the model as B2 and the purchase cost as B3, and then stores the power data as a1, a2, a3, B1, B2 and B3, and the data field of the stored power data includes the operating voltage, the model and the purchase cost.
Step S102, the power system server converts the data field into a general field of a power grid general model according to a preset field mapping table; the field mapping table stores the corresponding relation between the data field of the power data and the general field of the power grid general model.
The power grid general model can be an enterprise public information model issued by southern power grid companies, comprises core data model standard specifications such as power grid resources, equipment, customers and measurement, and stores corresponding general fields. Because the data fields of the power data adopted by different service systems may be different, the power system server may convert the data fields of different power data in the plurality of power service systems into the unified general field of the power grid general model through a pre-stored field mapping table storing the correspondence between the data fields of the power data and the general field of the power grid general model.
For example: similarly, for a certain transformer manufacturer, the data field used by the power service system a may be the manufacturer, and for the power service system B, the data field used may be the transformer manufacturer, and the two power service systems adopt different data fields although both record the data of the transformer manufacturer. At this time, the power system server may convert the different data fields into a general field of the power grid general model through a field mapping table, where the general field may be a transformer manufacturer, and then the field mapping table stores a mapping between a manufacturer and a transformer manufacturer field and a mapping between a transformer manufacturer and a transformer manufacturer field, so as to convert both a manufacturer of the power service system a and a transformer manufacturer in the power service system B into the general field transformer manufacturer of the power grid general model.
And step S103, writing the power data into the power grid general model by the power system server according to the general fields to form a plurality of power grid general service models.
Specifically, after the data field in the power service system is converted into the general field of the power grid general model, the power system server may write the corresponding power data into the power grid general model according to the general field model, for example, write the power data stored in the field of the manufacturer in the power service system a into the general field of the transformer manufacturer in the power grid general model.
And step S104, the power system server performs data splicing on the power data of the plurality of power grid general service models, and establishes the incidence relation of the plurality of power grid general service models.
The incidence relation of the power grid general service models refers to the incidence relation of data between different power grid general service models, and specifically, certain power data may be stored in two different power service systems, for example: the transformer data of a certain transformer may be partially stored in the power service system a, such as a production system, or partially stored in the power service system B, such as a marketing system, and the number of the transformer has been normalized by the data fields of the production system and the marketing system in step S103, so that the power system server may splice the transformer data after the normalized data fields according to the same transformer number, thereby establishing the association relationship between the production system and the marketing system.
Step S105, the power system server builds a power database model based on the incidence relation.
After the power system server obtains the association relations of the plurality of power service systems in step S104, the power database model may be constructed based on the association relations, for example, a corresponding production marketing model may be constructed according to the correspondence relations between the production systems and the marketing systems, so that the production marketing model including both the production system data and the marketing system data is successfully constructed as the information model of the power database with unified power information.
In the method for constructing the power database model, a power system server acquires a plurality of power data acquired by a plurality of power service systems and data fields of the plurality of power data; converting the data field into a general field of a power grid general model according to a preset field mapping table; the field mapping table stores the corresponding relation between the data field of the power data and the general field of the power grid general model; writing the electric power data into the power grid general model according to the general fields to form a plurality of power grid general service models; performing data splicing on the power data of the plurality of power grid general service models, and establishing an incidence relation of the plurality of power grid general service models; and constructing a power database model based on the incidence relation. According to the method and the system, the data fields of the electric power data collected by the electric power service systems are converted into the general fields of the electric power grid general model through the electric power system server, the incidence relation of the general service model is established through a data splicing mode after the electric power grid general service model is formed, and the electric power database is established based on the incidence relation, so that the establishment of the electric power database with unified electric power information is realized.
In one embodiment, as shown in fig. 2, the plurality of power grid generic service models may include a first power grid generic service model and a second power grid generic service model, and step S104 may include:
step S201, the power system server obtains a splicing field and splicing data under the splicing field; the splicing field is a field which is used for carrying out data splicing on the electric power data of the plurality of power grid general service models in the general field of the power grid general model;
the splicing field is a field which is used for performing data splicing on the electric power data of the plurality of power grid general service models in the general field of the power grid general model. Specifically, the concatenation field may be selected by the power system server according to different power service systems, for example: for the production system and the marketing system, the splicing field can be selected as a common equipment number and the like, and is used as a field for performing data splicing on the power data of the power grid general service model formed by the production system and the marketing system.
Step S202, if the first power grid general service model stores first splicing data matched with second splicing data stored in the second power grid general service model, the power system server performs data splicing on the first power grid general service model and the second power grid general service model, and establishes an incidence relation between the first power grid general service model and the second power grid general service model.
After the power system server obtains the splicing field in step S201, first, power data under the splicing field may be extracted from the splicing field from the first power grid general service model obtained by converting the power service system a, respectively, to be used as first splicing data, and simultaneously, power data under the splicing field may be extracted from the second power grid general service model obtained by converting the power service system B, to be used as second splicing data, and if there is a match between the second splicing data and the first splicing data, data splicing is performed on data stored in the first power grid general service model and the second power grid general service model based on the splicing data, so as to establish an association relationship between the first power grid general service model and the second power grid general service model.
Further, the concatenation field may include: the power equipment codes corresponding to the power data; the power device code includes a first power device code and a second power device code, and step S202 may further include:
and if the first power equipment code which is the same as the second power equipment code stored in the second power grid general service model is stored in the first power grid general service model, the power system server performs data splicing on the first power grid general service model and the second power grid general service model, and establishes the incidence relation between the first power grid general service model and the second power grid general service model.
The splicing field adopted by the power system server can be a power equipment code corresponding to power data, and for transformer equipment, data splicing among a plurality of power grid general service models can be carried out in a transformer code mode. Specifically, the power system server may extract, from the first power grid general service model, first transformer codes of all transformer devices stored in the first power grid general service model, extract, from the second power grid general service model, second transformer codes of all transformer devices stored in the second power grid general service model, select, from the first transformer codes, first transformer codes identical to the second transformer codes, as power data for data splicing, and select, from the first power grid general service model, power data corresponding to the first transformer codes and power data corresponding to the second transformer codes in the second power grid general service model, and perform data splicing, thereby establishing the first power grid general service model and the second power grid general service model.
For the power data that cannot be represented in a digitally encoded form only by words, for example, the concatenation field may further include a power device name corresponding to the power data, and the power device name may further include a first power device name and a second power device name, then step S202 may further include:
and if the first power grid universal service model stores the first power equipment name matched with the keyword of the second power equipment name stored in the second power grid universal service model, performing data splicing on the first power grid universal service model and the second power grid universal service model, and establishing the incidence relation between the first power grid universal service model and the second power grid universal service model.
Specifically, the power system server may extract a first power equipment name from the first power grid general service model, extract keywords in the first power equipment name, select a second power equipment name matched with the keywords of the first power equipment name in a keyword fuzzy matching manner, perform data splicing on the first power grid general service model and the second power grid general service model based on the equipment name, and further establish an association relationship between the first power grid general service model and the second power grid general service model.
In the embodiment, the power system server realizes data splicing of the power data stored in different power grid general service models based on the general fields of the unified power grid general model, and further establishes the incidence relation of the multiple power grid general service models.
In one embodiment, if the field mapping table does not store the general field of the power grid general model corresponding to the data field of the power data, the power system server stores the data field of the power data into the field mapping table as the general field of the power grid general model.
Since the field mapping table is a mapping table for correspondence between data fields of power data and general fields of the power grid general model, there may be a case where a general field of the power grid general model corresponding to a data field of certain power data is missing in the mapping table. Therefore, in this case, the power system server may directly use the data field of the power data lacking in the mapping table as the general field of the power grid general model, store the field in the field mapping table, and write the power data of the data field into the newly added general field in the power grid general model.
In the embodiment, the data field of the power data which is not contained in the field mapping table is written into the field mapping table, so that the power data in the data field can be written into the corresponding power grid universal model, the integrity of the power data is ensured, and the data integrity of the constructed power database model is ensured.
In one embodiment, a power service system includes: at least one of a grid scheduling system, a geographic information system, a production system, a marketing system, or a metering automation system.
The power grid dispatching system is mainly used for acquiring main grid information, monitoring data of the main grid information, analyzing safety and the like, the geographic information system is a GIS system and is mainly used for acquiring geographic position information such as the position of power equipment and the like, the production system and the marketing system respectively store production information and marketing information of the power equipment such as physical equipment information and customer information, and the metering automation system stores metering information used for recording and describing metering relation information of customers and the electric energy meter.
Further, the power data may include: at least one of a main network model data, a first geographic information data, a second geographic information data, a production data, a marketing data or an electric power metering data; step S101, may further include: the power system server acquires main network model data from a power grid dispatching system according to a dispatching system file transmission protocol; acquiring first geographic information data from a geographic information system in a data synchronous extraction mode, and acquiring second geographic information data by monitoring an electronic handover interface of the geographic information system through a monitoring system; acquiring production data from a production database of a production system through a data replication tool of a headquarter data center, and acquiring marketing data from a marketing database of a marketing system; and/or acquiring power metering data from the metering automation system according to a metering system file transfer protocol.
The first geographic information data represents geographic information data acquired from a geographic information system at the first stage, and the second geographic information data represents geographic information data acquired from a geographic information system at the middle and later stages. Specifically, the power system server may obtain a plurality of power data from different power service systems in different manners, for example, the main network information of the power grid scheduling system and the metering information of the metering automation system may be obtained and updated in a manner of reading an E file in a File Transfer Protocol (FTP) manner; reading first-stage GIS data from a GIS platform in a data synchronous extraction mode, monitoring an electronic handover interface through a monitoring system, and synchronously acquiring later-stage GIS data; production data can also be obtained from a production database of the production system and marketing data can also be obtained from a marketing database of the marketing system through a data replication tool of the headquarters data center.
In the above embodiment, the power system server respectively acquires the power data acquired by different power service systems, and synchronously acquires the power data from the different power service systems by using different data acquisition manners on the basis, which is beneficial to improving the real-time performance and accuracy of the acquired power data, and further can improve the accuracy of the power data stored in the constructed power database.
