Description

Technical Field

[0001] This disclosure relates to the field of power transmission line technology, and in particular to a method, apparatus and electronic device for calculating the swing angle coefficient. Background Technology

[0002] In power transmission line engineering, the planning of the tower head is a crucial component of tower design, and meeting insulation coordination requirements is a vital condition for designing the dimensions of the tower head components. To determine the tower head dimensions for various tower types, the swing angle of the insulator strings under different operating conditions, such as high operating voltage (strong winds), switching overvoltage, lightning overvoltage, and operational procedures, needs to be considered. In practical design, the allowable swing angle of the tower can be determined by the planned swing angle coefficient K. v It is calculated under the planned operating conditions, conductor and insulator string type conditions.

[0003] When the tower needs to be used for different working conditions, different conductors, and different insulator string types (lengths), the planned swing angle coefficient K is then adopted. v The value used to determine the allowable swing angle, and then to judge the gap between the insulator string and the tower components, clearly contains errors, resulting in the gap not meeting the requirements. If an increased K is assumed to be used... v The value is used as the allowable K value for the proposed tower. v If the value is too high, it will cause the towers to be replaced with larger ones.

[0036] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0037] The method and apparatus for calculating the swing angle coefficient according to embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0038] Figure 1 This is a flowchart illustrating a method for calculating the swing angle coefficient provided in an embodiment of this disclosure. This method can be executed independently or in conjunction with any other embodiment of this application.

[0039] like Figure 1 As shown, the method includes the following steps:

[0040] Step 101: Obtain the swing angle coefficient of the plan, and determine the vertical span corresponding to the swing angle coefficient of the plan based on the swing angle coefficient of the plan.

[0041] It should be noted that the swing angle coefficient calculation method provided in this embodiment can be executed by a swing angle coefficient calculation device. This device can be an electronic device, or software installed in an electronic device, and can be configured according to actual needs.

[0042] In this embodiment of the disclosure, after obtaining the planned swing angle coefficient K v1 Then, based on the swing angle coefficient K of the plan, v1 Determine the swing angle coefficient K of the plan. v1 The corresponding planned vertical span l v1 .

[0043] It should be noted that in related technologies, the planned sway angle coefficient K v This is the ratio of the vertical span to the horizontal span of a straight-line tower, and it can be used to calculate the allowable sway angle during tower design. This sway angle can be determined by the planned sway angle coefficient K. vIt is calculated under the planned operating conditions, conductor, and insulator string configuration. In other words, the planned swing angle coefficient corresponds to the planned operating conditions, the planned conductor, and the planned insulator string.

[0044] In some implementations, the planned sway angle coefficient K v1 Corresponding planned vertical span Among them, l H T is the planned horizontal span of the tower. +40 T1 represents the conductor tension of the planned conductor at high temperature (+40 degrees Celsius), W1 represents the conductor tension of the planned conductor under the planned operating conditions, and a represents the tower height difference coefficient.

[0045] It is understandable that the parameter T +40 T1 and T1 can be calculated from the conductor characteristic curve of the planned conductor.

[0046] Step 102: Calculate the planning sway angle corresponding to the planning sway angle coefficient based on the vertical span of the plan.

[0047] In this embodiment of the disclosure, based on the planned swing angle coefficient K v1 The sway angle coefficient K of the plan was calculated. v1 The corresponding planned vertical span l v1 Afterwards, it is possible to determine the vertical span l according to the plan. v1 Calculate the sway angle coefficient K of the plan. v1 Corresponding planning swing angle

[0048] In some implementations, the planned sway angle coefficient K v1 Corresponding planning swing angle Among them, P I For the wind load of the planned insulator string, G I P1 represents the self-weight of the planned insulator string, P1 represents the wind load on the planned conductor under the planned operating conditions, and W1 represents the vertical load on the planned conductor.

[0049] It should be noted that, in this embodiment, the wind load and self-weight of the insulator string have a relatively small impact on the calculation result of the sway angle coefficient, and are assumed to remain constant in this embodiment. Additionally, the planned horizontal span l of the tower... H It remains unchanged.

[0050] In this embodiment of the disclosure, the allowable sway angle of the planned tower remains unchanged under different operating conditions (such as strong wind, switching overvoltage, lightning overvoltage, strong wind, switching overvoltage, etc., i.e., different wind speeds, temperatures, etc.).

[0051] In this embodiment of the disclosure, the allowable sway angle of the planned tower remains unchanged under different conductor conditions (different conductor parameters).

[0052] In this embodiment of the disclosure, the allowable sway angle of the planned tower changes under different insulator string types (different insulator string lengths).

[0053] Step 103: Based on the equivalent model of the insulator string of the transmission tower, determine the equivalent tower slope of the left and / or right tilt of the transmission tower body according to the planned sway angle, the planned length of the insulator string, and the gap requirement value under the planned working conditions.

[0054] In this embodiment of the disclosure, the equivalent tower slope of the transmission tower body to the left and / or right can be determined based on the equivalent model of the insulator string of the transmission tower, according to the planned swing angle, the planned length of the insulator string, and the gap requirement value under the planned working conditions.

[0055] In this embodiment of the disclosure, without the need for a single-line diagram of the transmission tower (i.e., the external dimensions of the transmission tower are unknown), the equivalent tower body slope θ of the left and / or right deviation of the transmission tower body can be further calculated based on the equivalent model of the transmission tower insulator string.

[0056] In some embodiments, the equivalent model of the transmission tower insulator string is at least one of the following: an equivalent model of the centerline of a double-circuit (lower phase) insulator string; an equivalent model of the centerline of a single-circuit (side phase) insulator string; an equivalent model of the outline of a double-circuit (lower phase) insulator string; and an equivalent model of the outline of a single-circuit (side phase) insulator string. The above models are as follows... Figure 5-8 As shown, this will be described in detail later, and will not be repeated here.

[0057] Step 104: Determine the target vertical span corresponding to the target insulator string length based on the equivalent tower slope.

[0058] In some implementations, the target sway angle corresponding to the target insulator string length can be determined based on the equivalent tower slope and the target insulator string length; and then the target vertical span corresponding to the target insulator string length can be determined based on the target sway angle.

[0059] Step 105: Calculate the target swing angle coefficient corresponding to the target insulator string length based on the target vertical span corresponding to the target insulator string length.

[0060] In some implementations, the target swing angle coefficient corresponding to the target insulator string length can be determined based on the target vertical span corresponding to the target insulator string length and the conductor tension under the planned operating conditions.

[0061] In this embodiment of the disclosure, the operating conditions and the conductors in the planning conditions may also be changed.

[0062] In some implementations, when the planned operating conditions change to a target operating condition, the vertical span corresponding to the target operating condition can be determined based on the planned sway angle and the conductor wind load under the target operating condition. Furthermore, the sway angle coefficient corresponding to the target operating condition can be determined based on the target vertical span corresponding to the target operating condition and the conductor tension under the target operating condition.

[0063] In some implementations, the conductor in the planning conditions is changed to a target conductor. The target vertical span of the target conductor can be determined based on the planned sway angle, the wind load on the target conductor, and the vertical load on the target conductor. Furthermore, the target sway angle coefficient of the target conductor can be determined based on the target vertical span and the conductor tension of the target conductor.

[0064] In this embodiment, by obtaining the planned sway angle coefficient, the planned vertical span corresponding to the planned sway angle coefficient is determined. Based on the planned vertical span, the planned sway angle corresponding to the planned sway angle coefficient is calculated. Based on the shape of the transmission tower, the equivalent tower slope of the transmission tower is determined according to the planned sway angle, the planned insulator string length, and the gap requirement value under the planned working conditions. Based on the equivalent tower slope, the target vertical span corresponding to the target insulator string length is determined. Based on the target vertical span corresponding to the target insulator string length, the target sway angle coefficient corresponding to the target insulator string length is calculated. This method can accurately calculate the equivalent sway angle coefficient under different working conditions, conductors, and insulator string configurations without requiring other operations such as drawing gap diagrams. The operation is simple and convenient, effectively improving the engineering design efficiency of transmission towers. It effectively avoids situations where the gap between the insulator string and tower components does not meet the requirements due to incorrect equivalent values ​​of the sway angle coefficient, or where the allowable sway angle of the proposed tower is calculated using an artificially increased sway angle coefficient, resulting in a tower that is too large for the intended size.

This sway angle can be determined by the planned sway angle coefficient K. v It is calculated under the planned operating conditions, conductor, and insulator string configuration. In other words, the planned swing angle coefficient corresponds to the planned operating conditions, the planned conductor, and the planned insulator string.

[0070] In some implementations, the planned sway angle coefficient K v1 Corresponding planned vertical span Among them, l H T is the planned horizontal span of the tower. +40 T1 represents the conductor tension of the planned conductor at a high temperature (+40 degrees Celsius), T1 represents the conductor tension of the planned conductor under the planned operating conditions, and W1 represents the vertical load of the planned conductor.

[0071] It is understandable that the parameter T +40 T1 and T1 can be calculated from the conductor characteristic curve of the planned conductor.

[0075] Step 203: Calculate the target vertical span corresponding to the target operating condition based on the planned sway angle and the wind load on the conductor under the target operating condition.

[0076] In this embodiment, the allowable sway angle of the planned tower remains unchanged under different operating conditions (such as strong winds, switching overvoltages, lightning overvoltages, etc., i.e., different wind speeds, temperatures, etc.). Therefore, the planned sway angle is calculated... Afterwards, the swing angle can be determined according to the plan. Given the wind load P2 of the planned conductor under the target operating condition, determine the target vertical span l corresponding to the target operating condition. v2 .

[0080] It is understandable that the parameter T +40 T2 can be calculated from the conductor characteristic curve of the planned conductor.

[0081] In this embodiment, by obtaining the planned sway angle coefficient, the planned vertical span corresponding to the planned sway angle coefficient is determined. Based on the planned vertical span, the planned sway angle corresponding to the planned sway angle coefficient is calculated. Based on the planned sway angle and the conductor wind load under the target operating condition, the target vertical span corresponding to the target operating condition is calculated.

[0123] Step 404: Determine the target swing angle corresponding to the target insulator length based on the equivalent tower slope and the target insulator string length.

[0124] In this embodiment of the disclosure, after calculating the equivalent tower slope θ of the transmission tower, since the clearance requirement and margin S under the planned operating conditions are known, it is possible to determine the appropriate insulator string length l based on the equivalent tower slope θ and the target insulator string length l. c2 Determine the length l of the target insulator c2 Corresponding target sway angle

[0125] In some implementations, the equivalent model of the transmission tower insulator string is determined to be the equivalent model of the centerline of a double-circuit (lower phase) insulator string, such as... Figure 5 As shown, based on this wind deflection diagram, we can obtain:

[0126]

[0127] Where b is the horizontal distance from the suspension insulator string hanging point to the horizontal intersection of the tower body and the hanging point, S is the clearance requirement and margin under the planned operating conditions (strong wind, switching overvoltage, lightning overvoltage, strong wind, switching overvoltage, etc.), l c2 For the target insulator string length, Let θ be the target sway angle, and θ be the equivalent tower slope.

[0128] Similarly, the target swing angle in Equation 3 can be solved using a trial-and-error method.

[0129] In some implementations, the equivalent model of the transmission tower insulator string is determined to be the equivalent model of the centerline of a single-circuit (side-phase) insulator string, such as... Figure 6 As shown, based on this wind deflection diagram, we can obtain:

[0130]

[0131] Where b is the horizontal distance from the suspension insulator string hanging point to the horizontal intersection of the tower body and the hanging point, S is the clearance requirement and margin under the planned operating conditions (strong wind, switching overvoltage, lightning overvoltage, strong wind, switching overvoltage, etc.), l c2 For the target insulator string length, Let θ be the target sway angle, and θ be the equivalent tower slope.

[0132] Similarly, the target swing angle from method 4 can be used.

[0133] In some implementations, the equivalent model of the transmission tower insulator string is determined to be an equivalent model of the outline of a double-circuit (lower phase) insulator string, such as... Figure 7 As shown, this model, based on Equation 3, also needs to consider the influence of the length of the low-voltage side connecting tower hardware of the insulator string, the horizontal spacing of the split (including the equalizing ring, etc.), and the vertical spacing of the split (including the small sag, etc.).

[0134] In some implementations, the equivalent model of the transmission tower insulator string is determined to be an equivalent model of the outline of a single-circuit (side-phase) insulator string, such as... Figure 8 As shown, this model, based on Equation 4, also needs to consider the influence of the length of the low-voltage side connecting tower hardware of the insulator string, the horizontal spacing of the split (including the equalizing ring, etc.), and the vertical spacing of the split (including the small sag, etc.).

[0135] Step 405: Determine the target vertical span corresponding to the target insulator string length based on the target swing angle.

[0136] In this embodiment of the disclosure, after calculating the target sway angle Then, it can be based on the target's swing angle. Determine the target vertical span l corresponding to the target insulator string length. v4 .

[0137] In some implementations, based on the target yaw angle Calculate the vertical span corresponding to the length of the target insulator string. Among them, P I For the wind load of the planned insulator string, GI P1 represents the self-weight of the planned insulator string, P1 represents the wind load on the planned conductor under the planned operating conditions, and W1 represents the vertical load on the planned conductor.

[0138] Step 406: Determine the swing angle coefficient corresponding to the length of the target insulator string based on the target vertical span and the conductor tension under the planned working conditions.

[0139] In some implementations, the swing angle coefficient corresponding to the length of the target insulator string Among them, l v4 The target vertical span obtained in step 405, l H Where W1 is the planned horizontal span of the tower, W1 is the planned vertical load of the conductor, a is the tower height difference coefficient, and T is the planned horizontal span of the tower. +40 T1 is the conductor tension of the planned conductor under high temperature (+40 degrees Celsius).

[0140] It is understandable that the parameter T +40 T1 can be calculated from the conductor characteristic curve of the target conductor.

[0141] In this embodiment, by obtaining the planned sway angle coefficient, the planned vertical span corresponding to the planned sway angle coefficient is determined. Based on the planned vertical span, the planned sway angle corresponding to the planned sway angle coefficient is calculated. Based on the shape of the transmission tower, the equivalent tower slope of the transmission tower is determined according to the planned sway angle, the planned insulator string length, and the gap requirement value under the planned operating conditions. Based on the equivalent tower slope and the target insulator string length, the target sway angle corresponding to the target insulator length is determined. Based on the target sway angle, the target insulator length is determined. The target vertical span corresponding to the insulator string length is used to determine the swing angle coefficient corresponding to the target insulator string length based on the target vertical span and the conductor tension under the planned working conditions. This allows for accurate calculation of the equivalent swing angle coefficient under different working conditions, conductors, and insulator string configurations. The operation is simple and convenient, effectively improving the engineering design efficiency of transmission towers. It effectively avoids situations where the gap between the insulator string and tower components does not meet the requirements due to incorrect equivalent swing angle coefficient values, or where artificially increased swing angle coefficients are used to calculate the allowable swing angle of the proposed tower, resulting in towers being built too large for smaller ones.

[0155] As one possible implementation, the fourth computing module 904 is also used for:

[0156] In response to a change in the operating condition from the planned condition to the target operating condition, the target vertical span corresponding to the target operating condition is determined based on the planned sway angle and the conductor wind load under the target operating condition.

[0157] As one possible implementation, the fifth computing module 905 is also used for:

Furthermore, it eliminates the need for other operations such as drawing gap diagrams, making the operation simple and convenient. This effectively improves the engineering design efficiency of transmission towers and avoids situations where the gap between the insulator string and tower components does not meet requirements due to incorrect equivalent values ​​of the sway angle coefficient, or where artificially increased sway angle coefficients are used to calculate the allowable sway angle of the proposed tower, resulting in towers being oversized instead of undersized.
