Description

Technical Field

[0001] The invention belongs to the technical field of power transmission and transformation, and in particular relates to a fast and universal method for generating design parameters of a 35kV substation. Background Art

[0002] Driven by the power reform policy, distribution network users have increasingly urgent demands for electricity and higher requirements for power supply quality. In recent years, considering the reliability and convenience requirements in operation and maintenance, more and more corporate users have chosen to build 35kV substations on their own. In urban distribution networks, 35kV substations are more widely used and are closer to residents.

[0003] The design of 35kV substations by distribution network users mainly relies on professional design consulting companies for engineering design. The process is time-consuming and requires a lot of initial investment. It is difficult to quickly adapt to the needs of ordinary users, and the progress of power construction cannot quickly respond to the effect of shortening the construction cycle.

[0004] On the other hand, the existing 35kV substation design plan is presented in an overly professional way. Distribution network users, including corporate users who build their own substations and ordinary people, find it difficult to quickly and intuitively obtain key information about the proposed substation, such as the land size, investment cost, noise level, and appearance after completion, which are of greatest concern to users. As a result, distribution network users have difficulty in quickly and correctly interpreting the station construction information, which prolongs the design time. Summary of the invention

[0005] In order to overcome the defects and shortcomings of the prior art, the purpose of the present invention is to provide a fast and universal 35kV substation design parameter generation method, which is convenient for ordinary distribution network users to quickly extract key information for station construction.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A fast and universal method for generating design parameters of a 35 kV substation is operated in a substation design software of a computer device, and comprises the following steps: S1. According to the functional level requirements of the corresponding 35kV substation construction, the standardized layout principle of each functional layer module is set, and then the electrical equipment required by each functional layer module is modeled as a unit cabin model inside a rectangular block with set length, width and height; S2. According to the transportation conditions of the site and the distribution of the operation and maintenance channels of each functional layer module, each functional layer module is selected to form a corresponding unit cabin combination, and the relevant parameter information of the unit cabin is extracted to form a parameter information package of the corresponding unit cabin; S3. According to the electrical wiring diagram of the 35kV substation, the required unit cabins are retrieved and spliced ​​to form a layout diagram of the corresponding functional level; S4. According to the spliced ​​layout diagram, the parameter information packages of all unit cabins are superimposed together to generate the entire station information parameter package of the 35kV substation.

[0007] Preferably, the functional level requirements for building the 35kV substation include: main transformer, 35kV power distribution, 10kV power distribution, station transformer, grounding transformer, secondary equipment and other functions.

[0008] Preferably, the standardized layout principles of each functional layer module include: (1) Minimize the total footprint of each functional layer module; (2) The main transformer functional layer modules are arranged in a row on the ground, with an operation and maintenance channel of no less than one meter in width between the unit cabins where each transformer is located; (3) The 35kV power distribution function layer module and the 10kV power distribution function layer module are both arranged on the ground, and the 35kV power distribution function layer module and the 10kV power distribution function layer module are both arranged close to the main transformer function layer module; (4) The station transformer function layer module and the grounding transformer function layer module are preferably arranged without occupying any space. The station transformer function layer module and the grounding transformer function layer module are arranged on the second floor of the 35kV power distribution function layer module and / or the 10kV power distribution function layer module; In other embodiments, the station transformer functional layer module and the ground transformer functional layer module may also be arranged on the ground and be adjacent to the 10kV power distribution functional layer module, or be arranged in the area occupied by the 10kV power distribution functional layer module; (5) The secondary equipment function layer module is arranged on the second layer of the 35kV power distribution function layer module and / or the 10kV power distribution function layer module; (6) When the size of the splicing boundary between the functional layer modules differs from the size of the splicing boundary less than the set difference, the size of the corresponding functional layer module at the splicing boundary is modified to be equal to the size of the splicing boundary of another functional layer module to be spliced. The specific size refers to the length, width and height.

[0009] Preferably, the following design principles are adopted when forming the combination of unit cabins: (a) In order to facilitate the rapid retrieval of unit cabins for design, the unit cabins are subdivided according to the number of electrical equipment, and the name suffix of each unit cabin model is set to represent the number of electrical equipment; (b) First determine the type of electrical equipment, layout the unit cabins based on operation and maintenance requirements, and then determine the electrical structure of each unit cabin considering transportation conditions; (c) The floor plan module of each unit cabin is formed. The economic cost is marked in the upper left corner of the floor plan, the height of the unit cabin is marked in the upper right corner, and the dotted line indicates the splicable boundary of the unit cabin.

[0010] Preferably, the relevant parameter information of the unit cabin includes operating noise, floor space, cabin height, number of electrical equipment, and economic cost.

[0011] Preferably, the types of corresponding unit cabins include main transformer unit cabin, 35kV distribution switch cabinet unit cabin, 10kV distribution switch cabinet unit cabin, station transformer unit cabin, grounding transformer unit cabin, and control room unit cabin.

[0012] Preferably, when the corresponding unit cabins are retrieved for splicing, the selection and quantity of the electrical equipment need to be retrieved according to the unit cabin parameter information package, and the corresponding splicing boundaries are aligned to perform the model combination of the unit cabins according to the given layout principle.

[0013] Compared with the prior art, the present invention has the following advantages and beneficial effects: Compared with the shortcomings of the conventional 35kV substation in the prior art, which has a large workload for on-site survey and a long design and construction period, and thus cannot meet the needs of distribution network users for rapid station construction, the present invention compiles the entire station information into an information parameter package, so as to facilitate the formation of a design scheme that is generally applicable to various types of distribution network users during the design phase; the design scheme of the conventional 35kV substation is complex and difficult for distribution network users to interpret quickly and correctly, the present invention enables distribution network users to quickly obtain the corresponding station construction information through the information parameter package prepared, thereby speeding up the progress of station construction design.
