Detailed Description
The invention will be described in detail below with reference to the drawings in connection with embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.
The following detailed description is exemplary and is intended to provide further details of the invention. Unless defined otherwise, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the invention.
Example 1
Referring to fig. 1, a model nesting and information interaction method for an inter-provincial and intra-provincial two-level power market, comprising the steps of,
firstly, automatically extracting keywords from an intra-provincial data model of each province through a background algorithm, and storing the keywords in a model name keyword data information table; and the keywords of the provincial data model of each province are encoded according to the unified rule; obtaining coded data information;
secondly, inputting the coded data information of each province into a database according to a unified rule, and displaying a mapping relation; nesting the provincial models of each province according to the mapping relation to form provincial models with uniform formats; information interaction is realized by using a provincial model with uniform format; the model conversion of the intra-provincial model nest is adopted to unify the model data of each provincial into inter-provincial models with the same format, so that the smooth reading of inter-provincial power transaction information is ensured;
thirdly, setting an automatic checking function, comparing an inter-province model formed by nesting inter-province models with an original inter-province model, and identifying and cross-comparing information of inter-province tie line channels according to keywords to generate model data of a missing end; and highlighting the model data of the missing end to be fed into the database.
The model nesting and information interaction method for the inter-provincial and intra-provincial two-stage power markets solves the main technical problem that the inter-provincial and intra-provincial information model is transmitted to inter-provincial transactions to cause information overlapping or inconsistent structures due to the difference between each inter-provincial power network model and the power transaction data structure; the method comprises the steps of converting different information models in a province into a unified province-to-province model by establishing a unified model converter, deleting redundant information, supplementing missing information, and carrying out self-building and alarming on the models by a tool to realize seamless nesting of the information models in each province. The model and the method can provide consistent and complete basic information model data for the stable and reliable operation of the electric power market transaction in provinces and provinces.
In the first step, taking the "group A and the second thermal power plant #1 machine" in the model as an example when extracting keywords, the background algorithm is automatically split into six name keywords of "A", "B", "second", "thermal power", "power generation" "# 1".
On the basis of embodiment 1, in the first step, the keywords of each provincial information model are identified and encoded, keywords are automatically extracted from the provincial data model through a background algorithm and are stored in a model name keyword data information table to be marked by a semicolon; "partition".
When encoding is performed according to the unified rule, the parameters set in the encoding rule include any one or more of the following parameters: name, type, province, capacity, voltage of the generator set. Taking the provinces as examples, the provinces can be ordered when coding is carried out, and then digital coding is carried out from top to bottom; for example, the code of Hebei province is 001, the code of Shanxi province is 002, etc.; the provinces can also be encoded according to pinyin, so that Hebei province is encoded as hebei, shanxi province is encoded as shanxi and the like; whether the digital coding or the pinyin coding is adopted, after keywords are extracted from the provincial database of each provincial, the keywords are coded according to a unified rule, so that nesting and interaction of subsequent models can be ensured.
In another embodiment of the present invention, when encoding the extracted keywords, the parameters may be set to priority, for example, priority order, and the priority order is sequentially set to name, type, belonging province, capacity and voltage of the generator set from first to second. By classifying the information according to priority, the proportion of comparison passing can be set according to single or grouping information; to reduce coding errors.
Between the first step and the second step, the coded data information of each province needs to be integrated after coding; deleting the repeated information; the information integration comprises the following two modes:
one way, for a plurality of data information pending of information appearing in different provinces, if the province of the data information can be determined, the data information is retained in the province model library according to the province of the data information, and duplicate information is deleted at the same time;
otherwise, if the province of the data information cannot be determined, pushing to manual selection and deleting the repeated information. In this way, it is described that the model boundary attribution of the data information is ambiguous, that is, multiple different information of the same model appear in two or more provinces, including, but not limited to: quotation data, physical topology data, network data, etc. Because the province can not be determined to be assigned to a certain province or to an inter-province model, the province model needs to be pushed to manual selection for comparison.
In the third step, the name, type, area, capacity and voltage level information of the generator set may be manually adjusted as required to generate missing end model data, and the missing model information may be stored in the database.
When automatic inspection is performed, the inspection time and the alarm level are set according to the model level or classification relation of the intra-provincial or inter-provincial models. The classification relationships include any one or more of the following: market members, generators, loads, and tie lines. The alarming mode comprises a front-end interface, a short message or a mail informing user.
As shown in fig. 2, a model nesting and information interaction system for provincial and inter-provincial power markets, for implementing the above method, comprises:
the background algorithm module 1 is used for extracting keywords from the provincial data model, storing the keywords in a model name keyword data information table, and encoding the keywords of each provincial model according to a unified rule; obtaining coded data information;
the database module 2 is used for inputting data according to unified rules through unified coded data information of each province; nesting the provincial models of each province according to the mapping relation of the data to form provincial models with uniform formats; information interaction is realized by using a provincial model with uniform format;
and the automatic checking module 3 is used for comparing the inter-province model formed by nesting the inter-province model with the original inter-province model, identifying and cross-comparing the information of the inter-province connecting line channel according to the keywords, automatically generating model data of the missing end, and supplementing the model data of the missing end into the database.
A model nesting and information interaction device for inter-provincial and intra-provincial power markets, comprising a memory for storing a computer program and a processor coupled to the memory; a processor for implementing the steps of the method as described above when executing the computer program.
