Power grid planning, also known as transmission system planning, is based on load prediction and power supply planning. The power grid planning determines when and where to put in what type of transmission line and the number of loops thereof so as to achieve the transmission capacity required in the planning period, and the cost of the transmission system is minimized on the premise of meeting various technical indexes.
In the field of power grid planning, in each feasibility research stage of medium and low voltage distribution network infrastructure projects, basic units (power supply substations) need to write feasibility research reports. The compilation of the feasibility research report needs to inquire a plurality of data from the power grid planning system, and because the data exist in different forms and the formats of the forms are inconsistent, the data can only be manually filled by workers at present, so that the problems of large filled data quantity, repeated work, difficult data check, high error rate and the like exist, and the feasibility research work quality of the infrastructure engineering is greatly influenced.
Specifically, please refer to fig. 2. In the conventional feasibility study approval process, the process is divided into four stages, and the content and time requirements of each stage are shown in fig. 2. Each stage is described in detail below.
First stage (power supply branch): the content completed by the corresponding professional responsible person or the main responsible person comprises content one: collecting a question bank, compiling and reporting a project research plan, a research adjustment plan and a content II: and editing and reporting the project researched scheme according to the review opinions.
Second stage (grid planning center): the content completed by its professional responsible person includes content three: issuing project plan (i.e. project workable plan, workable adjustment plan) to the third stage and content four: collecting the expert evaluation opinions, evaluating the project plan and issuing the evaluation opinions. And if the technical examination is not passed, the power supply branch office is led to complete the corresponding work content II. If so, the process proceeds to the third stage. Other tasks that need to be performed include checking the amount and archiving, etc.
Stage three (expert library): the project examination is completed by an expert group, and specifically comprises project scheme readiness examination, project scheme compliance examination, project scheme technical examination and project scheme implementation effect examination. And when the second-stage technology examination conclusion passes, project plan examination is required, and the second-stage verification amount is continued after the project plan examination passes.
Fourth stage (grid planning center): the central responsible person verifies that the amount is correct and then passes the project plan. If the audit is passed, filing processing is carried out; if the audit is not passed, the corresponding responsible person of the power supply branch office in the other first stage is responsible for revising the project scheme.
As can be seen from the above, the project research schemes and the research adjustment schemes are mainly compiled by the corresponding professional responsible persons or main responsible persons of each power supply branch office, and they need to perform data query from the power grid planning system to collect a problem library, which requires a large amount of data to be filled in. And the power grid planning system is mainly responsible for a power grid planning center, if data errors can cause errors of data filled by a power supply substation end but the errors are not found, the compiled project scheme can not pass examination, and the waste of manpower work is caused.
Based on the method, the invention provides a form generation method of a power grid planning system.
The following is a detailed description of an embodiment of a form generation method of a power grid planning system according to the present invention.

Therefore, the existing problem bank can be directly obtained from the power grid planning system by each branch office. The project plan compilation is carried out by directly utilizing the established question bank data, so that the workload of filling and reporting the data can be greatly reduced, and the data error probability is reduced.
The problem status table in the problem bank is established by professional responsible persons. As shown in fig. 3, a specific process of establishing the problem current situation table by the professional responsible person is that the professional responsible person cleans current situation data of all lines and transformers of the distribution network from the distribution network planning system, analyzes problems of the lines and the transformer area of the distribution network, and establishes a corresponding problem current situation table according to the problems of the lines and the transformer area of the distribution network. The problem status table specifically includes: the current situation and the existing problems of the medium-voltage public distribution line, the current situation and the existing problems of the public distribution transformer and the infrastructure project library of the medium-voltage and low-voltage distribution network.
The problem of possible errors also exists in directly obtaining the problem bank from the power grid planning system. Therefore, after acquiring the problem bank, the power supply branch needs to verify the quality of the data in the problem bank and check whether the data is wrong. If there is a mistake, the data with a problem in the question bank needs to be modified. Specifically, the data with problems in the problem database is modified by the power supply branch office and reported to the relevant professional responsible person (referring to the professional responsible person in the power grid planning center), so that the professional responsible person modifies the database (namely, the problem database) according to the modified data.
S200: and a power supply substation end creates a current situation analysis table with a theme corresponding to the problem current situation table, and captures column labels of the problem current situation table as column labels of the current situation analysis table.
For example, a "medium-voltage power supply line current status analysis" table corresponding to "medium-voltage utility distribution line current status and existence of problem" and a "utility distribution line current status analysis" table corresponding to "utility distribution line current status and existence of problem" are newly created. Column labels of the problem presence table need to be captured as column labels of the presence analysis table.
For example, the column labels of the "area and county", the "substation name" and the "feeder name" of the column label are extracted from the "current situation and problem existing medium-voltage public distribution line" table as the column labels of the "current situation analysis of medium-voltage power supply line" table.
And (3) capturing the 'the region and county', the 'transformer substation name', the 'feeder line name' and the 'distribution transformer name' of the column labels from the 'public distribution transformer current situation and problem existing' table as the column labels of the 'public distribution transformer current situation analysis' table.
S300: and the power supply branch terminal fills the data corresponding to the problem current situation list label into the table corresponding to the current situation analysis list label.
It should be noted that, from "current state of medium-voltage public distribution line and problem," grab column label "safe current (a)", "substation name", "fault indicator (set) with communication function", "two remote terminals (set)", "power supply radius (km)", "power supply section classification", "connection mode", "feeder name", "end voltage (kV)", "annual power supply amount (kWh)", "annual maximum current (a)", "annual maximum load rate (%)", "three remote terminals (set)", "whether or not optical fiber coverage is achieved", "area country", commissioning date "," line property "," main cable model "," main cable length (km) "," main overhead line length (km) "," main insulated overhead model "," power supply voltage (km) "," power supply section classification "," line mode ", and" state of the power supply section ", and" line quality ", respectively, The current situation analysis of the medium-voltage power supply line of the corresponding line is filled in 33 data corresponding to the model number of the bare trunk conductor, the number of automatic sections of the trunk line, the total trunk length (km), the attached public variable capacity (kVA), the attached public variable transformer number, the attached public transformer total number, the attached capacity (kVA), the attached special variable capacity (kVA), the attached special transformer number and the like.
The method comprises the steps of filling 19 data corresponding to the public distribution transformer current situation and the existing problems, such as 'the district and county belonging to a public distribution transformer' from a grabbing column label ',' the power supply partition classification ',' the distribution transformer name ',' the distribution transformer model ',' the rated capacity (kVA), 'the commissioning date', 'the substation name', 'the feeder name', 'the number of outgoing lines and loops (loops) of a transformer district', 'the main line path of a transformer district low-voltage main line', 'the power supply radius (m),' the load property ',' the number of users (users) realizing one meter, the number of smart meters (blocks), 'the number of users (users) realizing low-voltage meter reading', and the like, into 'the public distribution transformer current situation analysis' of the corresponding public transformer.
S400: and the power supply branch terminal generates a feasibility research report or feasibility research summary according to the content of the current situation analysis table.
It should be noted that the generated feasibility study report or the feasibility study summary also needs to be uploaded to the power grid planning system.
The embodiment provides a method for generating a form of a power grid planning system, which comprises the steps that a power supply branch end obtains a problem base from a power grid planning system, then a corresponding current situation analysis table is built on the basis of the problem base, data of the current situation analysis table are filled by using the corresponding relation between the problem current situation table and the current situation analysis table in the problem base, and finally a feasibility research report or feasibility research summary can be generated by using the content of the current situation analysis table. Compared with the traditional process, the problem situation table is generated at the power grid planning system end, so that the problem base is formed for the power supply substation end to compile the project scheme, and the problems that compiling personnel of each power supply substation inquire data from the power grid planning system, the data volume is large, repeated work is difficult, the data checking is difficult, the error rate is high and the like in manual data filling are avoided.
