[0001] The invention belongs to the technical field of distribution network design, and in particular relates to a method and device for optimizing the K value of a distribution network conductor. Background Art

[0002] Conductors are an important part of the distribution network. The conductor K value is an important parameter of the conductor. It is the ratio of the maximum allowable tension of the conductor to the rated breaking force of the conductor. The actual tension of the overhead conductor can be determined by the conductor K value, which facilitates the design of other factors of the distribution network, such as conductor sag value, pole selection, etc. It is an important parameter to ensure the safety of the distribution network.

[0003] In the process of distribution network design, the setting of conductor K value is usually determined according to the type of distribution network, the type of conductor and the regulations of the power grid project area.

[0004] However, due to differences in climate and terrain conditions in various regions, the conductor K value determined by the above method usually does not match the overall distribution network, which will lead to inaccurate pole models selected in subsequent processes such as pole type selection, posing a safety hazard to the operation of the distribution network. Summary of the invention

[0005] The purpose of the present invention is to provide a method and device for optimizing the K value of a distribution network conductor, so as to improve the selection accuracy of the K value of the conductor, provide a data basis for the subsequent distribution network design process, and reduce the safety hazards of the distribution network.

[0021] Furthermore, assigning K value to the pole position with non-open tension resistance property in the distribution network includes:

[0022] Get the K value of the rod points at both ends of the tension section where the rod points with the tension property turned off are located;

[0023] When the K values ​​of the rod points at both ends of the tension section are both the first K value or the second K value, the first K value or the second K value is assigned to the rod points that do not have the tension property turned on.

[0024] Furthermore, when the K values ​​of the rod points at both ends of the tension section are respectively the first K value and the second K value, the second K value is assigned to the rod point that does not have the tension property turned on.

[0025] Furthermore, checking the initial K value based on the cross arm bending moment includes:

[0026] Compare the cross arm bending moment with the allowable bending moment of the cross arm angle:

[0028] Furthermore, before obtaining the initial K value that passes the verification, the following steps are also included:

[0029] Subtract the first threshold from the initial K value that has passed the verification and then add the second threshold; the second threshold is less than the first threshold;

BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Figure 1 This is a flow chart of a method for optimizing the K value of a distribution network conductor according to an embodiment of the present invention;

[0044] Figure 2 The present invention is a schematic structural diagram of a device for optimizing the K value of a distribution network conductor according to an embodiment of the present invention. DETAILED DESCRIPTION

[0045] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] In the design process of the distribution network, a large number of calculations are integrated. After determining the type of pole at each pole location, the K value of the conductor needs to be calculated so that the accurate model of the pole can be calculated through the K value of the conductor. The K value is the ratio of the maximum allowable tension of the conductor when stringing to the rated breaking force of the conductor, and is a commonly used data in the power system. In layman's terms, it also reflects the tightness of the conductor, which is an important technical indicator in the design of the distribution network and is related to the safety of the distribution network.

[0047] The present invention discloses a method for optimizing the K value of a distribution network conductor. Figure 1 As shown, the following steps are included: step S110, obtaining the tension property of each pole point in the distribution network, and generating a pole point set with open tension property; step S120, assigning an initial K value to each pole point in the pole point set; step S130, selecting a first K value and a second K value from a number of initial K values; wherein the first K value is less than the second K value; step S140, assigning a first K value or a second K value to each pole point in the pole point set; step S150, assigning a K value to a pole point with non-open tension property in the distribution network; step S160, determining the K value of the conductor between two adjacent pole points according to the K values ​​of the two adjacent pole points.

[0048] The present invention assigns an initial K value to each pole point, selects a first K value and a second K value from multiple initial K values, and determines the conductor K value by using the first K value and the second K value. This can improve the selection accuracy of the conductor K value, provide a data basis for the subsequent distribution network design process, and reduce the safety hazards of the distribution network.

[0049] Since the K value reflects the tightness of the conductor in the distribution network and is a complete conductor in a tension section, there should be a unique K value in a tension section. The calculation of the K value should be based on the tension section, that is, the set of pole positions with tension properties turned on.

[0050] In one embodiment, assigning an initial K value to each pole site in the pole site set includes: assigning an initial K value to each pole site according to a geographical location of the power grid project, or assigning an initial K value to each pole site according to a type of conductor.

[0051] Specifically, when selecting the initial K value, if there is a regulation (industry standard or regional standard, etc.), the initial K value is obtained according to the regulation. If there is no regulation, it is determined whether it belongs to the Southern Power Grid project. If so, the default initial K value of the Southern Power Grid project is used. If there is no regulation and it does not belong to the Southern Power Grid project, the initial K value is determined according to the type of wire, such as the initial K value of the bare wire is 2.5, the initial K value of the insulated wire is 3.0, and so on.

[0052] The initial K value is the basic value of the conductor K value. In the distribution network design process, since the adjustment of the conductor K value involves a large amount of data, usually the conductor K value is not calculated in detail. Any slight error will bring unexpected consequences. Therefore, the conventional practice is to use the initial K value to design the distribution network without optimization.

[0053] In the embodiment of the present invention, after a detailed investigation and analysis of the role of the conductor K value and its impact on other components, it is found that although recalculating the conductor K value will increase the amount of calculation to a certain extent, it will also greatly increase the operational safety of the distribution network. On the other hand, it can also provide data support for the subsequent determination of the pole model, and then select a more suitable pole model, so as to achieve the purpose of reducing the total cost of the distribution network.

[0054] In an embodiment of the present invention, verifying the initial K value based on the cross-arm bending moment includes: comparing the cross-arm bending moment with the allowable bending moment of the cross-arm angle steel; when the cross-arm bending moment is greater than or equal to the allowable bending moment, increasing the initial K value by a first threshold to obtain a new initial K value, and recalculating the cross-arm bending moment using the new initial K value until the cross-arm bending moment is less than the allowable bending moment to obtain an initial K value that passes the verification.

[0055] For the convenience of calculation, an initial K value is assigned to each rod position in the rod position set. Then, the corresponding wire breaking force is queried in the wire model database according to the wire model. , then through Calculate the tension of the conductor on the cross arm, that is, the conductor tension , K is the initial K value, and finally To determine the calculated cross arm bending moment M Is it less than the allowable bending moment of the cross arm angle steel? , when it is less than, it means that the current initial K value meets the requirements, otherwise increase the initial K value and continue to repeat the verification process. n is the number of cross arms at the pole position, is the maximum value of the conductor ice coating and the active load. For the first n The distance between a pole position and the previous pole position.

[0056] As a specific method, in the process of increasing the K value, the initial K value is added to the first threshold, and verification is continued until the changed initial K value passes the verification, so that the initial K value that passes the verification is obtained.

[0057] In order to save calculation time, the first threshold is usually set to a larger value, but due to the large value of the first threshold, the accuracy of the K value that has been verified may be reduced. For example, when the K value is 4.5, it is verified to be passed, and the first threshold is 0.8, the K value is 5.3, but when the K value is 4.9, it may have been verified to be passed, but due to the large span of the threshold of 0.8, the optimal K value is missed.

[0058] Therefore, the first threshold is subtracted from the initial K value that has passed the verification, and then the second threshold is added; the second threshold is less than the first threshold; the initial K value after adding the second threshold is used to calculate the theoretical pole strength, and the execution continues.

[0059] Therefore, when the K value that passes the verification is obtained, the first threshold is subtracted from the K value and the second threshold is added. The second threshold here is less than the first threshold, and the second threshold is the calculation accuracy of the K value. In other words, the accuracy of the initial K value is adjusted by adding two thresholds to make the initial K value more accurate.

[0060] For example, the initial K value is 2.5, and the first K value increase threshold is 0.5. When the K value is checked, the K value is 4.5 and the check fails, but the K value is 5.0 and the check passes. At this time, the K value that passes the check is 5.0. However, since the K value increases directly from 4.5 to 5.0, and the K value precision requirement is 0.1, the precision is not high when the K value is 5.0, and then the K value is accurately checked when the K value is 4.6 (the calculation process is 5.0-0.5+0.1=4.6). Specifically, the calculation starts with a step size of 0.1. If the check passes when the K value is 4.6, the final K value that passes the check is 4.6. If the K value is 4.6 and the check fails, the K value is set to 4.7 for verification. If the check still fails, the K value is set to 4.8 for further verification. If the check still fails, the K value is set to 4.9 for further verification. If the check still fails, 5.0 is taken as the K value that passes the check.

[0061] When the K value of each pole point with tension resistance is verified, in order to simplify the construction of the distribution network, the verified initial K values ​​are sorted to obtain a K value set, and then the first K value and the second K value are selected from the K value set based on the selection threshold, thereby reducing the difficulty of distribution network construction.

[0062] In this embodiment, the sorting method can be from large to small or from small to large. The largest K value is determined as the second K value. When the K values ​​are arranged from large to small, the K values ​​of the first 20% positions are determined as the first K value. Then, each pole point in the pole point set is assigned a first K value or a second K value. The specific rule is: when the K value is greater than the first K value, the second K value is used as the K value of the pole point. When the K value is less than or equal to the first K value, the first K value is used as the K value of the pole point.

[0063] After assigning the first K value or the second K value to each pole point in the pole point set, the method further includes: comparing the K values ​​of the pole points at both ends of each tension segment; when the K values ​​of the pole points at both ends of the tension segment are not equal, re-obtaining the tension properties of each pole point in the distribution network and continuing the execution.

[0064] That is to say, after determining the K values ​​of all rod points with open tension properties, the K values ​​of the rod points at both ends of each tension segment must be equal. If the K values ​​of the rod points at both ends of a certain tension segment are not equal, the tension segment needs to be reset.

[0065] Specifically, in this embodiment, the tension property of the previous rod point of the rod point corresponding to the second K value is modified to the open tension property, and then the process returns to the representative span calculation step to continue execution.

[0066] Of course, it is not impossible for a tension section to have two K values. There are some exceptions where two K values ​​will appear. For example, when the tension section has only two rod positions, the K values ​​of the two rod positions may be different. In another case, if all the rod positions in the tension section do not have the tension wire conditions, the tension section may also have two K values. In this case, the second K value is assigned to the rod position that does not have the tension property.

[0067] In one embodiment, after the K values ​​of all the pole positions with tension properties are determined, assigning K values ​​to the pole positions with non-open tension properties in the distribution network includes the following steps: obtaining the K values ​​of the pole positions at both ends of the tension section where the pole positions with non-open tension properties are located; when the K values ​​of the pole positions at both ends of the tension section are the first K value or the second K value, assigning the first K value or the second K value to the pole positions with non-open tension properties. In another special case, when the K values ​​of the pole positions at both ends of the tension section are the first K value and the second K value, respectively, assigning the second K value to the pole positions with non-open tension properties.
