The following description of preferred embodiments of the invention will be made in further detail with reference to the accompanying drawings.
The application mainly provides a new method for inquiring the data of the power dispatching report, and mainly relates to a method for inquiring and acquiring the remote measuring data of the power dispatching. This application mainly is solved the inquiry of power scheduling telemetering measurement data among the prior art too loaded down with trivial details and because the too slow defect of inquiry speed that causes of attribute, through providing dedicated database and specific attribute to the realization is fast obtains corresponding telemetering measurement data according to telemetering measurement attribute, and concrete scheme is as follows:
the query method of the electric power telemetry data comprises two parts: a telemetry analysis library and a database generation part; and a data query portion.
The telemetry resolution library and database generation part comprises:
the method comprises the steps of analyzing and translating telemetering data uploaded by a transformer substation in advance, screening effective telemetering from the telemetering data uploaded by the power dispatching automation system by utilizing a front telemetering point number, analyzing and translating the name of the effective telemetering into the attribute of the effective telemetering data, and matching the attribute with a corresponding telemetering ID number. Correspondingly storing the attribute of the analyzed effective telemetering data and the telemetering ID number of the effective telemetering data together to form a telemetering analysis library;
in the prior art, the query time is influenced by the fact that more attributes of uploaded telemetry data are directly queried by using the uploaded telemetry data, and meanwhile, a lot of invalid telemetry data exist in the telemetry data, so that the telemetry attributes set by the method are the telemetry data required by query, and the valid telemetry attributes comprise the names of the transformer stations, the voltage levels, the equipment types and the telemetry types. As the telemetering data can be uploaded to the power dispatching system, for the purpose of realizing the query of the application, the uploaded telemetering data is screened, and screening is carried out by using the preposed point number, as shown in fig. 2, the preposed telemetering definition table is read, whether the telemetering data is valid is judged by using the preposed point number, the valid telemetering data is reserved, otherwise, the telemetering data is discarded, and the specific judgment mode is that the preposed point number of the telemetering data is more than 1, the telemetering data is valid, otherwise, the telemetering data is discarded. The prefix point number is an attribute of the telemetry data that indicates the telemetry data is in the set of telemetry data, and is fixed. The pre-definition table is a table of a database, and comprises a plurality of attributes, wherein the four attributes are available, and the parsing is to extract the four attributes. And then analyzing the attribute corresponding to the telemetry name through a front telemetry definition table: the method comprises the steps of storing the telemetry ID and the attribute matching mode of the telemetry ID to form a telemetry analysis library, then storing effective telemetry data in a database, and correspondingly storing the stored position and the telemetry ID in a telemetry sampling definition table in a matching mode, thereby forming a telemetry sampling definition table with the telemetry ID corresponding to the telemetry data storage position.
Storing the analyzed effective telemetering data in a database, and associating the effective telemetering data with the telemetering ID; storing the telemetry ID of the valid telemetry data in association with a database storage location of the valid telemetry data forms a telemetry sample definition table. Because the storage position of the effective telemetering data is stored in the telemetering sampling definition table, the corresponding effective telemetering data can be quickly read according to the storage position.
During query, the power dispatching system provides a selectable data search function, a user can input search data according to actual query requirements, can input query attributes and other contents, obtains corresponding telemetering ID according to the attributes of the effective telemetering data in the telemetering analysis library, and then searches the effective telemetering data related to the telemetering ID in the database according to the telemetering ID. The method comprises the steps of adding a retrieval function in the power dispatching system, using a human-computer interaction interface including but not limited to a mouse, a touch screen, a mobile phone terminal and the like as an input end of retrieval data, wherein the supported retrieval data comprise the attribute of telemetry data, inquiring telemetry ID matched with the input attribute data in a telemetry analysis library through the input attribute data, inquiring a storage address of the telemetry data corresponding to the telemetry ID in a telemetry acquisition definition table, reading the telemetry data stored at the address in a database to obtain the data required to be retrieved and inquired, and downloading or exporting, displaying and the like the data. During query, the position of the valid telemetry data stored in the database is mainly queried in the telemetry sampling definition table according to the valid telemetry ID, and then the corresponding valid telemetry data is queried and obtained according to the storage position.
The invention discloses a novel power dispatching report query method. The power dispatching report query method comprises two processes of generating a telemetering analysis library and querying data.
The method comprises the steps of firstly screening effective telemetering in a preposed telemetering sampling table of a dispatching automation system by using a preposed point number, then resolving the name of the effective telemetering into a transformer substation, a voltage grade, an equipment type and a telemetering type, and storing the resolved telemetering characteristics and a telemetering ID number thereof to form a telemetering resolving library.
The query data of the power scheduling report query method comprises the steps of firstly providing selectable query conditions according to contents in a telemetering analysis library, then searching a telemetering ID number in the telemetering analysis library according to the selectable conditions, then searching a database storage position in a telemetering sampling definition table according to the telemetering ID number, and finally reading database data according to the searched storage position.
The method for inquiring the power dispatching report can greatly reduce redundant telemetering data inquiry, avoids inquiring invalid data attributes, further improves the inquiry speed and accuracy of data, and is convenient for power dispatching personnel to make reports.
When the electric power data is inquired, only a front telemetering definition table and a telemetering sampling definition table in a dispatching automation system are needed, the front telemetering definition table is responsible for explaining and translating data uploaded by a transformer substation, and a Chinese name in a data explanation channel table is uploaded by using a front point number. And the telemetry sample definition table is a table for recording the storage position of the telemetry data in a database. As shown in fig. 1, the two tables may be related by telemetry ID number to enable indexing of the data.
The invention firstly utilizes the preposed point number to screen out the effective telemetering data, and abandons the ineffective telemetering data, thereby greatly reducing the searching range of the data. And then, the Chinese name in the prepositive telemetering sampling definition table is analyzed, and the Chinese name is analyzed into four parts, namely a voltage grade, a transformer station name, an equipment name and a telemetering type, so that effective telemetering data attributes can be screened out, and data searching can be directly and rapidly realized. And finally, storing the analyzed telemetering characteristics and the telemetering ID number thereof to form a telemetering analysis library.
The telemetering analysis library provided by the invention contains effective data to be inquired and effective attributes of the data to be inquired. And using the four analyzed characteristics of the remote measurement as selectable query conditions. The power dispatcher can retrieve the valid data and the telemetry attributes thereof according to the provided query conditions.
And searching the ID number of the determined telemetry in a telemetry analysis library according to the determined telemetry characteristics, searching the storage position of the telemetry in the data in a telemetry sampling definition table according to the telemetry ID number, and inquiring and reading the data according to the storage position.
It is clear that the specific implementation of the invention is not restricted to the above-described embodiments, but that various insubstantial modifications of the inventive process concept and technical solutions are within the scope of protection of the invention.
