Description

Technical Field

[0001] This invention relates to the field of icing measurement technology, and in particular to a method, apparatus, electronic device, and storage medium for measuring wire icing. Background Technology

[0002] Icing is a natural phenomenon. If icing applied to power lines, communication lines, buildings, and other facilities exceeds their capacity, it may cause damage or destruction. Therefore, it is necessary to obtain information on the amount and trend of icing at or near these facilities in a timely manner in order to take necessary measures.

[0003] In existing technologies, methods for obtaining the actual icing thickness can be broadly categorized into online monitoring and manual measurement methods. Online icing monitoring devices used on transmission lines often require the installation of measuring equipment on the main load-bearing suspension or tension insulator strings. This involves significant engineering work and may also create safety hazards. Manual measurement methods typically determine the actual icing thickness by collecting icing samples, measuring the wire diameter, the length and short diameter of the wire after icing, the icing length, and weighing the icing. However, this method cannot obtain icing thickness in a timely manner and has certain limitations, requiring substantial manpower and resources. Summary of the Invention

[0004] In view of this, in order to solve the technical problems of existing online monitoring methods for wire icing having safety hazards, manual measurement methods not only failing to obtain icing thickness in a timely manner, but also having certain limitations and requiring a large investment of manpower and resources, this invention provides a method, device, electronic device and storage medium for measuring wire icing.

[0021] Using a preset second algorithm, the resultant force direction, the resultant force magnitude, the wind speed, the included angle, and the attribute parameters are calculated to obtain the average ice thickness under the actual ice density of the target wire.

[0022] The actual icing density of the target wire is determined based on the average icing thickness and the attribute parameters.

[0023] Based on the average ice thickness and the actual ice density, determine the standard value of ice thickness under the target wire standard ice density;

[0024] The average ice thickness, the actual ice density, and the standard ice thickness are determined as the icing parameters of the target wire in the icing environment.

[0025] As one possible implementation, the attribute parameters include the diameter and length of the target wire. The step of using a preset second algorithm to calculate the average icing thickness of the target wire under the actual icing density, based on the resultant force direction, the resultant force magnitude, the wind speed, the included angle, and the attribute parameters, includes:

[0026] By inputting the direction of the resultant force, the magnitude of the resultant force, the wind speed, the included angle, the diameter, and the length into the following set of equations, the average icing thickness under the actual icing density of the target wire is obtained:

[0027]

[0033] Secondly, embodiments of the present invention provide a measuring device for wire icing. A target wire is placed in an icing environment to be measured. The target wire is horizontally suspended through two preset fixed points. A tension measuring device is installed on the suspension wire at each fixed point. An environmental detection device is installed in the icing environment. The measuring device for wire icing includes:

[0034] The first determining module is used to determine the attribute parameters of the target wire, wherein the attribute parameters are the initial parameters of the target wire before icing;

[0035] The second determining module is used to determine the resultant force suspending the target wire by means of the tensile measuring device and to determine the current environmental parameters of the icing environment by means of the environmental detection device when it is determined that the target wire is iced.

[0039] The technical solution provided by this invention involves setting a target wire in an icy environment to be measured. The target wire is horizontally suspended through two preset fixed points, and a tension measuring device is set on the suspension wire at each fixed point. An environmental detection device is set in the icy environment. The method determines the attribute parameters of the target wire, which are the initial parameters of the target wire before icing. When it is determined that the target wire is icy, the resultant force suspending the target wire is determined by the tension measuring device, and the current environmental parameters of the icy environment are determined by the environmental detection device. Based on the attribute parameters, resultant force, and the aforementioned environmental parameters, the icing parameters of the target wire in the icy environment are determined. This technical solution involves suspending the target wire in an icy environment and, upon confirming icing, acquiring the resultant force on the suspended wire and environmental parameters under icing conditions. Based on these attribute parameters, resultant force, and environmental parameters, the icing parameters of the target wire in an icy environment are determined. This avoids the safety hazards caused by adding measuring sensors to the insulator hardware strings that mainly bear the wire load in existing online measurements of transmission lines. It also avoids the limitations of manual measurement methods and the large amount of manpower and resources required. This solution enables a more accurate and simpler method to promptly determine the icing data of the target wire in an icy environment, thereby determining the severity of icing based on this data and allowing for timely and accurate implementation of corresponding anti-icing, anti-icing, and de-icing measures.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] See Figure 1 This is a schematic diagram of an application scenario involved in an embodiment of the present invention.

[0049] Figure 1 The application scenario shown is an icy environment to be measured. The icy environment may include: a wire sample 11 of a preset length (hereinafter referred to as "target wire 11"), two fixed points 12 for suspending the target wire, a tension measuring device 13 set on the suspension wire of each fixed point, and an environmental detection device 14 installed in the icy environment.

[0050] The target wire 11 can be a wire sample with preset gravity, diameter, and length. Optionally, the target wire 11 can be a round wire, a square wire, or a diamond-shaped wire; this embodiment of the invention does not impose any limitations on this.

[0051] Prior to this, since the icing thickness of round wire is the most representative data among the icing data that needs to be obtained, the target wire 11 mentioned above can be a round wire.

[0052] The two fixing points 12 mentioned above can be used to suspend the target wire. Optionally, each fixing point 12 can suspend one end of the target wire 11.

[0053] The aforementioned tension measuring device 13 can be a tension sensor, or it can be both a tension sensor and an angle sensor. This embodiment of the invention does not impose any limitations on this. Figure 1 The application scenario shown uses only the tensile measuring device 13 as a tensile sensor for illustration.

[0054] The aforementioned environmental monitoring device 14 may include, but is not limited to, a wind direction measuring device, a wind speed measuring device, and a temperature measuring device. The wind direction measuring device can be used to measure the wind direction in an icing environment. The wind speed measuring device can be used to measure the wind speed in an icing environment. The temperature sensor can be used to measure the current temperature of the icing environment.

[0055] In one embodiment, when the tension measuring device 13 includes only a tension sensor, the tension sensor can be used to measure and obtain the magnitude of the resultant force suspending the target wire. Each tension sensor can be used to measure the tension at one end of the target wire; therefore, the magnitude of the resultant force suspending the target wire can be the sum of the tensions from the two tension sensors.

[0056] In another embodiment, when the tension measuring device 13 includes a tension sensor and an angle sensor, the tension sensor can be used to measure the suspension tension of the target wire 11, and the angle sensor can be used to measure the angle between the suspension wire of the target wire 11 and the vertical line perpendicular to the ground, i.e., the wind deflection angle, so as to calculate the suspension tension and the wind deflection angle according to the laws of mechanics, thereby obtaining the magnitude and direction of the resultant force of the target wire 11.

[0057] In this embodiment of the invention, the target wire 11 is installed in an icing environment where the icing parameters are to be measured. If a power transmission line used in actual applications is erected in the icing environment, then since it is installed in the same icing environment, the icing condition of the power transmission line erected in the icing environment can be determined by measuring the icing parameters of the target wire.

[0058] In one embodiment, the target wire 11 should meet the following conditions: First, it should have good hardness and be not easily bent when subjected to icing; second, it should have a suitable diameter, and if necessary, the influence of wire diameter on icing thickness can be considered according to relevant literature; third, the surface roughness should be basically consistent with the requirements of the simulated object or the corresponding standard; fourth, the length of the target wire 11 should be basically consistent with the distance between the two suspension wire fixing points 12; fifth, after suspension, the suspension wire should be perpendicular to the ground, the target wire 11 should be parallel to the ground, and the tension measured by the tension measuring device on the two suspension wires should be consistent, and the value should be half the weight of the target wire 11 when there is no wind and no ice.

[0059] In one embodiment, the tension measuring device 13 for the suspension line at each fixed point 12 should be as lightweight as possible to avoid significantly affecting the accuracy of the measured tension, suspension line deflection angle, etc. Depending on the needs and technical conditions, the aforementioned tension measuring device 13 can measure multiple physical quantities, such as the magnitude and direction of the resultant force.

[0060] It should be noted that the method of setting up the aforementioned target cable 11 can be as follows: Figure 1 The suspension method shown can also be a support method, and the embodiments of the present invention do not limit this.

[0061] The method for measuring wire icing provided by the present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the present invention.

[0062] See Figure 2 This is a flowchart of an embodiment of a method for measuring wire icing provided by the present invention. Figure 2 The procedure shown is for measurement Figure 1 The icing parameters of target cable 11 in an icing environment in the application scenario. For example... Figure 2 As shown, the process may include the following steps:

[0063] Step 201: Determine the attribute parameters of the target cable. The above attribute parameters are the initial parameters of the target cable before icing.

[0064] The aforementioned attribute parameters refer to the initial parameters of the target cable before icing, that is, the attribute parameters of the target cable when it is installed, which may include, but are not limited to, the initial weight, diameter, and length of the target cable.

[0065] In this embodiment of the invention, a technician can set up a target wire in an icy environment to be measured. The target wire is horizontally suspended through two preset fixed points, and a tension measuring device is installed on the suspension wire at each fixed point. An environmental monitoring device is also installed in the icy environment. Optionally, the environmental monitoring device can be installed in a location outside the target wire in the icy environment, such as next to the target wire, or at any location at the same height as the target wire.

[0066] In one embodiment, the executing entity of this invention may obtain the aforementioned attribute parameters of the target wire from a preset database.

[0067] In another embodiment, the executing entity of this invention can obtain the aforementioned attribute parameters of the target cable input by the user through a visual interface.

[0068] Step 202: If the target wire is found to be icy, determine the resultant force suspending the target wire using a tensile measuring device, and determine the current environmental parameters of the icing environment using an environmental monitoring device.

[0069] The aforementioned environmental monitoring device can be used to detect environmental parameters in an icy environment, including but not limited to: wind direction measuring device, wind speed measuring device, and temperature measuring device. Correspondingly, the aforementioned environmental parameters may include wind speed, wind direction, and temperature.

[0070] The aforementioned tension measuring device can be used to measure the resultant force of a suspended target wire. The tension measuring device may include a tension sensor, or a tension sensor and an angle sensor.

[0071] The resultant force of the aforementioned suspended target wire may include the magnitude of the resultant force, or the magnitude and direction of the resultant force.

[0072] In one embodiment, when the above-described tension measuring device includes only a tension sensor, the tension sensor can be used to measure and obtain the magnitude of the resultant force suspending the target wire. Each tension sensor can be used to measure the tension at one end of the target wire; therefore, the magnitude of the resultant force suspending the target wire can be the sum of the tensions from the two tension sensors.

[0073] In another embodiment, when the above-mentioned tension measuring device includes a tension sensor and an angle sensor, the tension sensor can be used to measure the suspension tension of the suspended target wire, and the angle sensor can be used to measure the angle between the suspension wire of the suspended target wire and the vertical line perpendicular to the ground, i.e., the wind deflection angle, so as to calculate the suspension tension and the wind deflection angle according to the laws of mechanics, thereby obtaining the magnitude and direction of the resultant force of the suspended target wire.

[0074] In one embodiment, the environmental measurement device may include a temperature measurement device. Therefore, the execution subject of this embodiment can measure the temperature value under icing conditions using the temperature measurement device and determine whether the temperature value is less than a preset temperature threshold. If the temperature value is determined to be less than the temperature threshold, it can be determined that the target wire meets the icing conditions, and thus the target wire is determined to be iced, thereby executing this step.

[0075] Based on this, when the target wire is determined to be icy, the executing entity of this embodiment of the invention can determine the resultant force suspending the target wire through a tensile measuring device, and determine the current environmental parameters of the icy environment where the target wire is located through an environmental detection device.

[0076] Step 203: Based on the above attribute parameters, resultant force, and environmental parameters, determine the icing parameters of the target wire in an icing environment.

[0077] The aforementioned icing parameters may include the icing thickness and density of the target wire, as well as the estimated icing type, etc., and the embodiments of the present invention do not limit these parameters.

[0078] In practical applications, icing is primarily caused by meteorological conditions. Icing can occur when environmental conditions such as temperature, humidity, and wind speed reach certain values. Overhead power lines, wind turbine blades, and buildings, widely distributed in icing environments, are particularly vulnerable to the adverse effects of icing. Therefore, it is necessary to conduct icing measurements, data accumulation, and analysis to promptly understand icing and its growth trends and take necessary measures. Icing thickness, especially when converted to standard density (900 kg / m³), is also crucial. 3 The average icing thickness of round wires is often used as a measure of the severity of icing.

[0079] In this embodiment of the invention, the executing entity can determine the icing parameters of the target wire in an icing environment based on the aforementioned attribute parameters, resultant force, and environmental parameters. If a power transmission line is assumed to be in this icing environment, since the target wire and the power transmission line in the actual application are in the same icing environment, determining the icing parameters of the target wire in the icing environment allows for the determination of the icing parameters of the power transmission line in the actual application. This enables prevention and disaster analysis based on the icing parameters, as well as the determination of de-icing initiation, de-icing current magnitude, and estimated de-icing time based on these parameters.

[0080] As for how the icing parameters of the target wire in an icing environment are determined based on property parameters, resultant force, and environmental parameters, these will be explained in detail below. Figure 3 and Figure 4 The process shown will be explained in detail here.

[0081] The technical solution provided by this invention involves setting a target wire in an icy environment to be measured. The target wire is horizontally suspended through two preset fixed points, and a tension measuring device is set on the suspension wire at each fixed point. An environmental detection device is set in the icy environment. The method determines the attribute parameters of the target wire, which are the initial parameters of the target wire before icing. When it is determined that the target wire is icy, the resultant force suspending the target wire is determined by the tension measuring device, and the current environmental parameters of the icy environment are determined by the environmental detection device. Based on the attribute parameters, resultant force, and the aforementioned environmental parameters, the icing parameters of the target wire in the icy environment are determined. This technical solution involves suspending the target wire in an icy environment and, upon confirming icing, acquiring the resultant force on the suspended wire and environmental parameters under icing conditions. Based on these attribute parameters, resultant force, and environmental parameters, the icing parameters of the target wire in an icy environment are determined. This avoids the safety hazards caused by adding measuring sensors to the insulator hardware strings that mainly bear the wire load in existing online measurements of transmission lines. It also avoids the limitations of manual measurement methods and the large amount of manpower and resources required. This solution enables a more accurate and simpler method to promptly determine the icing data of the target wire in an icy environment, thereby determining the severity of icing based on this data and allowing for timely and accurate implementation of corresponding anti-icing, anti-icing, and de-icing measures.

[0082] See Figure 3 This is a flowchart of an embodiment of another method for measuring wire icing provided by the present invention. Figure 3 The process shown is in Figure 1 Based on the illustrated process, taking a tensile testing device (including a tensile sensor) and an environmental monitoring device (including a wind direction measuring device and a wind speed measuring device) as an example, this section describes in detail how the icing parameters of the target wire are determined in an icing environment. Figure 3 As shown, the process may include the following steps:

[0083] Step 301: Determine the attribute parameters of the target cable. The above attribute parameters are the initial parameters of the target cable before icing.

[0084] For a detailed description of step 301, please refer to the description in step 201, which will not be repeated here.

[0085] Step 302: When it is determined that the target wire is icy, the magnitude of the resultant force suspending the target wire is measured and obtained by a tension sensor, and the wind direction of the icing environment is determined by a wind direction measuring device, and the wind speed of the icing environment is determined by a wind speed measuring device.

[0086] Step 303: Determine the angle between the wind direction and the axis of the target wire.

[0087] The following provides a unified explanation of steps 302 and 303:

[0088] The aforementioned tension sensor is used to measure and obtain the magnitude of the resultant force on the suspended target wire.

[0089] The aforementioned wind direction measuring device is used to measure wind direction in icy environments.

[0090] The aforementioned wind speed measuring device is used to measure wind speed in icy environments.

[0091] The wind direction and speed mentioned above refer to the wind direction and speed in the icing environment where the target wire is located.

[0092] The magnitude of the resultant force mentioned above refers to the resultant force of the suspension target wire, which can be the sum of the tension of the tension sensor corresponding to the suspension wire at each fixed point.

[0093] In one embodiment, when the execution subject of this invention determines that the target wire is icy, it can measure and obtain the magnitude of the resultant force suspending the target wire through a tension sensor, measure the wind direction of the icing environment through a wind direction measuring device, and measure the wind speed of the icing environment through a wind speed measuring device.

[0094] Then, the angle between the aforementioned wind direction and the axis of the target wire can be determined. The aforementioned angle can be positive or negative, and this embodiment of the invention does not limit it.

[0095] Step 304: Obtain the preset density of icing for the target wire.

[0096] The aforementioned preset density refers to the preset icing density of the target wire, which can be determined by technicians based on their measurement experience.

[0097] In one embodiment, since the actual icing density of the target wire cannot be calculated, the implementing entity of this embodiment can obtain the density obtained by a technician based on measurement experience as a basis for calculation, so as to determine the icing parameters of the target wire in the icing environment according to the preset density.

[0098] Optionally, the executing entity of this embodiment of the invention can obtain the preset density of icing of the target wire input by the technician through a visual interface, so as to determine the icing parameters of the target wire at the preset density.

[0099] Step 305: Using the preset first algorithm, calculate the preset density, resultant force, wind speed, included angle, and attribute parameters to obtain the thickness value of the icing of the target wire at the preset density.

[0100] Step 306: Convert the thickness value of the icing of the target wire at the preset density to the standard thickness value at the standard density.

[0101] Step 307: Determine the thickness value and the standard thickness value as the icing parameters of the target wire in an icing environment.

[0102] The following provides a unified explanation of steps 305 and 306:

[0103] The first algorithm mentioned above refers to a preset algorithm. The execution subject of this embodiment of the invention can use the first algorithm to calculate the preset density, resultant force, wind speed, included angle and attribute parameters to obtain the thickness value of the ice coating of the target wire at the preset density.

[0104] The above attribute parameters are the initial parameters of the target cable. They can be the attribute parameters of the target cable before installation, and may include the initial weight, diameter, and length of the target cable.

[0105] In this embodiment of the invention, the preset density, resultant force, wind speed, included angle, initial gravity, diameter, and length of the target wire can be input into the equation set in the following formula (I) to obtain the thickness value of the icing of the target wire at the preset density, and the thickness value is determined as the icing parameter of the target wire in the icing environment.

[0106] Formula (1)

[0107] Among them, the above As the initial gravity, the above For the preset density of the target wire, the above For gravitational acceleration, the above The above refers to the thickness value of the ice coating on the target wire. For the diameter of the target wire, the above For length, the above For dynamic reference wind pressure, the above The angle mentioned above is the included angle, and T is the magnitude of the resultant force mentioned above. The above is the component of the force acting on the target wire perpendicular to the ground. The component of force perpendicular to the axis of the target wire, as described above For the component force parallel to the axis of the target wire, the above For the aforementioned wind speed, the aforementioned The above is an air density correction factor. This refers to the amount of air per unit volume.

[0108] Optionally, when limiting wind speed requires altitude correction or the temperature deviates significantly from 15°C, the above... The values ​​are given in the corresponding table of IEC 60826; otherwise, 1.0 is used. The above... At 15℃ and 101.3 kPa, a concentration of 1.225 kg / m³ was measured. 3 .

[0109] Optionally, by solving the system of equations in equation (I) above, the thickness of the icing on the target wire at the preset density can be obtained. .

[0110] It should be noted that since the target wire is not long enough, the wind force on the cross-section of the target wire, including the icing, should be considered during the calculation. Therefore, a dynamic reference wind pressure can be added to the above equations. This dynamic reference wind pressure is related to the height of the target wire. Taking this dynamic reference wind pressure into account can eliminate the influence of the altitude of the target wire on the measured icing parameters of the target wire in an icing environment.

[0111] In one embodiment, after obtaining the thickness value of the icing of the target wire at a preset density, in order to more accurately measure the thickness of the icing of the target wire, the thickness value at the preset density can be converted into the thickness value at a standard icing density (hereinafter referred to as the "standard thickness value" for ease of description). The standard density can be 900 kg / m³. 3 .

[0112] Specifically, the thickness of the icing on the target wire at a preset density can be converted into a standard thickness value at a standard density using the following formula (II):

[0113] Formula (II)

[0114] Among them, the above The above refers to the standard thickness value for icing of the target wire. For the diameter of the target wire, the above The above is the preset density for icing the target wire. The above refers to the thickness value of the ice coating on the target wire. The standard density for icing the target wire.

[0115] The aforementioned thickness values ​​and standard thickness values ​​can then be determined as the icing parameters for the target wire in an icing environment.

[0116] Furthermore, in one embodiment, the environmental monitoring device may also include a temperature measuring device for measuring the ambient temperature of the icing environment. Therefore, the aforementioned environmental parameters may also include the ambient temperature of the icing environment.

[0117] Based on this, in execution Figure 3 Before the process shown, it can be determined whether the ambient temperature is lower than the preset ambient temperature threshold.

[0118] Optionally, if it is determined that the ambient temperature is lower than the ambient temperature threshold, it indicates that the current icing environment has reached the conditions for freezing, and therefore, the procedure can be executed. Figure 3The steps shown in the process are used to calculate the icing thickness of the target wire and determine the icing situation.

[0119] Conversely, if the ambient temperature is determined to be greater than or equal to the ambient temperature threshold, it indicates that the current icing environment has not reached the conditions for icing, and the target wire is not iced. In this case, the process can be terminated and repeated. Figure 3 The steps of the process shown.

[0120] The technical solution provided by this invention determines the attribute parameters of the target wire, which are the initial parameters of the target wire before icing. When icing is determined, a tension sensor determines the magnitude of the resultant force suspending the target wire, a wind direction measuring device determines the wind direction of the icing environment, a wind speed measuring device determines the wind speed of the icing environment, and the angle between the wind direction and the axis of the target wire is determined. A preset density of icing on the target wire is obtained. A preset first algorithm is used to calculate the preset density, resultant force, wind speed, angle, and attribute parameters to obtain the thickness value of icing on the target wire at the preset density. The thickness value of icing on the target wire at the preset density is converted into a standard thickness value at a standard density. The thickness value and the standard thickness value are determined as the icing parameters of the target wire in the icing environment. This technical solution determines the icing thickness of the target wire at a preset density by using environmental parameters such as wind speed, wind direction, and the angle between the wind direction and the axis of the target wire. This thickness is then converted into a standard thickness value at a standard density. The thickness value and the standard thickness value are used to define the icing parameters of the target wire in an icing environment. This avoids the safety hazards caused by adding measuring sensors to the insulator hardware strings that mainly bear the wire load in existing online measurements of transmission lines. It also avoids the limitations of manual measurement methods and the high manpower and material costs. This allows for a more accurate and simpler method to promptly determine the icing data of the target wire in an icing environment, thereby determining the severity of icing and enabling timely and accurate implementation of corresponding anti-icing, anti-icing, and de-icing measures.

[0121] See Figure 4 This is a flowchart of an embodiment of a method for measuring wire icing provided by the present invention. Figure 4 The process shown is in Figure 1 Based on the illustrated process, taking a tensile testing device (including a tensile sensor and an angle sensor) and an environmental monitoring device (including a wind direction measurement device and a wind speed measurement device) as examples, this section specifically describes how to determine the icing parameters of the target wire in an icing environment. Figure 4 As shown, the process may include the following steps:

[0122] Step 401: Determine the attribute parameters of the target cable. The above attribute parameters are the initial parameters of the target cable before icing.

[0123] For a detailed description of step 401, please refer to the description in step 201, which will not be repeated here.

[0124] Step 402: When it is determined that the target wire is icy, the tension of the suspension wire suspending the target wire is measured and obtained by the tension sensor, the angle between the suspension wire suspending the target wire and the vertical line perpendicular to the ground is measured and obtained by the angle sensor, i.e., the wind deflection angle, the wind direction of the icing environment is determined by the wind direction measuring device, and the wind speed of the icing environment is determined by the wind speed measuring device.

[0125] Step 403: Calculate the tension of the suspension line and the wind deflection angle according to the laws of mechanics to obtain the magnitude and direction of the resultant force.

[0126] Step 404: Determine the angle between the wind direction and the axis of the target wire.

[0127] The following provides a unified explanation of steps 402 to 404:

[0128] The aforementioned tension sensor is used to measure and obtain the suspension tension of the target wire. Each suspension wire can be equipped with a tension sensor, and the suspension tension obtained by each tension sensor can correspond to the suspension tension of the target wire suspended by each suspension wire. Correspondingly, the total suspension tension of the target wire can be the sum of the two suspension tensions.

[0129] The aforementioned angle sensor can be used to measure and obtain the angle between the suspension line of the target cable and the vertical line perpendicular to the ground, that is, the wind deflection angle corresponding to each suspension line of the target cable.

[0130] The wind direction measuring device described above can be used to measure the current wind direction in an icing environment.

[0131] The aforementioned wind speed measuring device can be used to measure the current wind speed in an icy environment.

[0132] The wind direction and speed mentioned above refer to the wind direction and speed in the icing environment where the target wire is located.

[0133] The magnitude of the resultant force mentioned above refers to the magnitude of the resultant force suspending the target wire, and the direction of the resultant force mentioned above refers to the direction of the resultant force suspending the target wire.

[0134] The aforementioned included angle refers to the angle between the suspension line at the fixed point and the vertical line perpendicular to the ground, and this included angle can be directly measured by the aforementioned angle sensor.

[0135] In one embodiment, when the execution subject of this invention determines that the target wire is icy, it can measure and obtain the suspension tension of the target wire by means of a tension sensor, measure the wind direction of the icy environment by means of a wind direction measuring device, measure the wind speed of the icy environment by means of a wind speed measuring device, and determine the wind deflection angle between the suspension wire and the vertical line perpendicular to the ground by means of an angle sensor.

[0136] Based on this, the executing entity of this invention can calculate the tension of the suspension line and the wind deflection angle between the suspension line and the ground according to the laws of mechanics, thereby calculating the magnitude and direction of the resultant force of the suspended target line. Correspondingly, the resultant force of the suspended target line can include the magnitude and direction of the resultant force.

[0137] Then, the angle between the aforementioned wind direction and the axis of the target wire can be determined. The aforementioned angle can be positive or negative, and this embodiment of the invention does not limit it.

[0138] Step 405: Using the preset second algorithm, calculate the resultant force direction, resultant force magnitude, wind speed, included angle, and attribute parameters to obtain the average icing thickness under the actual icing density of the target wire.

[0139] The above-mentioned actual icing density refers to the actual icing density of the target wire.

[0140] The aforementioned second algorithm refers to a preset algorithm. The execution subject of this embodiment of the invention can use the second algorithm to calculate the resultant force direction, resultant force magnitude, wind speed, included angle, and attribute parameters to obtain the average icing thickness of the target wire under the actual icing density.

[0141] The above average ice thickness refers to the actual ice thickness of the target wire, which is the average thickness under the actual density of the ice.

[0142] The aforementioned attribute parameters refer to the initial parameters of the target wire before icing, which may include the diameter and length of the target wire.

[0143] Based on this, the executing entity of this invention can input the resultant force direction, resultant force magnitude, wind speed, included angle, diameter, and length into the equation set in equation (iii) below to obtain the average icing thickness of the target wire under the actual icing density:

[0144] Formula (3)

[0145] Among them, the above The above represents the average ice thickness. For diameter, the above For length, the above For dynamic reference wind pressure, the above For the direction of the above resultant force, the above The angle mentioned above is the included angle, and T is the magnitude of the resultant force mentioned above. For the component of force perpendicular to the ground acting on the target wire, the above For the component force perpendicular to the axis of the target wire, the above For the component force parallel to the axis of the target wire, the above For wind speed, the above The above is an air density correction factor. This refers to the amount of air per unit volume.

[0146] Optionally, when limiting wind speed requires altitude correction or the temperature deviates significantly from 15°C, the above... The values ​​are given in the corresponding table of IEC 60826; otherwise, 1.0 is used. The above... At 15℃ and 101.3 kPa, a concentration of 1.225 kg / m³ was measured. 3 .

[0147] Therefore, by solving the equations in equation (iii) above, the average ice thickness of the target wire under the actual ice density can be obtained.

[0148] It should be noted that, since the target wire is not long enough, the wind force acting on the cross-section of the target wire, including the icing area, should be considered in the calculation. Considering the influence of the target wire's altitude on air density and wind pressure, a dynamic reference wind pressure calculation formula is added to the above equations. Incorporating this dynamic reference wind pressure can minimize the impact of the target wire's altitude on the measured icing parameters of the target wire in an icing environment.

[0149] Step 406: Determine the actual icing density of the target wire based on the average icing thickness and attribute parameters.

[0150] Step 407: Determine the standard value of icing thickness under the target wire standard icing density based on the average icing thickness and the actual icing density.

[0151] Step 408: Determine the average ice thickness, actual ice density, and standard ice thickness as the icing parameters of the target wire in an icing environment.

[0152] The following provides a unified explanation of steps 406 to 408:

[0153] The aforementioned attribute parameters refer to the initial parameters of the target wire before it is covered with ice. In addition to diameter and length, they may also include the initial gravity of the target wire.

[0154] The aforementioned standard icing density refers to the standard icing density of the target wire, which can be 900 kg / m. 3 .

[0155] The above-mentioned standard value for icing thickness refers to the thickness of the icing on the target wire at the standard density.

[0156] In practical applications, the actual ice density of transmission line wires can be used to determine the icing characteristics. Combined with the ice thickness, the icing characteristics are a crucial factor in determining the magnitude of the de-icing current and the duration of the de-icing process, thus facilitating the overall planning and scheduling of de-icing for multiple transmission lines. However, in existing technologies, online monitoring of transmission line icing has failed to effectively obtain measured results of ice density.

[0157] Based on this, the executing entity of this invention can, after calculating the average ice thickness of the target wire at the actual ice density, further determine the actual ice density of the target wire based on the average ice thickness and attribute parameters.

[0158] Specifically, the aforementioned attribute parameters may include the initial weight, diameter, and length of the target wire. The executing entity of this embodiment can input the average ice thickness, initial weight, length, and diameter into the following formula (iv) to obtain the actual ice density of the target wire:

[0159] Formula (IV)

[0160] Among them, the above For the actual icing density of the target wire, the above The above is the component of the force acting on the target wire perpendicular to the ground. As the initial gravity, the above The above represents the average ice thickness. For the diameter of the target wire, the above The length of the target wire.

[0161] Based on this, the actual icing density of the target wire can be obtained by solving the above formula (iv).

[0162] Subsequently, after determining the average icing thickness and actual icing density of the target wire, the executing entity of this embodiment can further convert the average icing thickness and actual icing density of the target wire under icing conditions into standard icing thickness values ​​under standard icing density, so as to provide technicians with more accurate icing parameters of the target wire under icing conditions. The aforementioned standard density can be 900 kg / m. 3 .

[0163] Specifically, the average ice thickness and the actual ice density mentioned above can be used to determine the standard value of ice thickness under the target wire standard ice density using the following formula (V):

[0164] Formula (5)

[0165] Among them, the above The above are standard values ​​for icing thickness. For diameter, the above For the actual icing density, the above The above represents the average ice thickness. This is the standard icing density.

[0166] By solving equation (v) above, the standard value of icing thickness under the standard icing density of the target wire can be obtained.

[0167] Subsequently, the average ice thickness, the actual ice density, and the standard value of ice thickness can be determined as the icing parameters of the target wire in an icing environment.

[0168] Furthermore, after determining the average density of icing on the target wire, the executing entity of this embodiment can infer the icing type of the target wire based on the average density and determine the icing type as the icing parameter of the target wire.

[0169] Furthermore, in one embodiment, the environmental monitoring device may also include a temperature measuring device for measuring the ambient temperature of the icing environment. Therefore, the aforementioned environmental parameters may also include the ambient temperature of the icing environment.

[0170] Based on this, in execution Figure 4 Before the steps of the process shown, it can be determined whether the ambient temperature is lower than the preset ambient temperature threshold.

[0171] Optionally, if it is determined that the ambient temperature is lower than the ambient temperature threshold, it indicates that the current icing environment has reached the conditions for icing, and the target wire may be icing. Therefore, the procedure can be executed. Figure 4 The steps shown in the process are used to calculate the icing thickness of the target wire and determine the icing situation.

[0172] Conversely, if the ambient temperature is determined to be greater than or equal to the ambient temperature threshold, it indicates that the current icing environment has not reached the conditions for icing, and the target wire is not iced. In this case, the process can be terminated and repeated. Figure 4 The steps of the process shown.

[0173] The technical solution provided in this invention determines the attribute parameters of the target wire, which are the initial parameters of the target wire before icing. When icing is confirmed, a tension sensor measures and obtains the suspension tension of the target wire, and an angle sensor measures and obtains the angle between the suspension line and the vertical line perpendicular to the ground (i.e., the wind deflection angle). A wind direction measuring device determines the wind direction of the icing environment, and a wind speed measuring device determines the wind speed of the icing environment. The suspension tension and wind deflection angle are calculated according to mechanical laws to obtain the resultant force and the net force. The direction is determined by the angle between the wind direction and the axis of the target wire. Using a preset second algorithm, the resultant force direction, resultant force magnitude, wind speed, angle, and attribute parameters are calculated to obtain the average icing thickness under the actual icing density of the target wire. Based on the average icing thickness and attribute parameters, the actual icing density of the target wire is determined. Based on the average icing thickness and actual icing density, the standard value of icing thickness under the standard icing density of the target wire is determined. The average icing thickness, actual icing density, and standard value of icing thickness are determined as the icing parameters of the target wire in an icing environment. This technical solution, by including an angle sensor for the suspension wire in the environmental monitoring device, can utilize the angle sensor to measure the angle between the suspension wire and the vertical line perpendicular to the ground. Based on this angle, the average ice thickness of the target wire at the actual ice density, as well as the actual ice density of the target wire, can be determined. This provides technicians with more accurate icing parameters for the target wire in an icing environment. This avoids the safety hazards caused by adding measuring sensors to the insulator hardware strings that mainly bear the wire load in existing online measurements of transmission lines. It also avoids the limitations of manual measurement methods and the large investment of manpower and resources. It achieves a more accurate and simple method to promptly determine the icing data of the target wire in an icing environment, and based on this icing data, to determine the severity of icing, thereby enabling timely and accurate implementation of corresponding anti-icing, anti-icing, and de-icing measures.

[0174] To verify the above Figure 3 and Figure 4 The consistency of icing parameters of the target wire measured by the process shown in the diagram under an icing environment is illustrated below with an example:

[0175] Assuming the property parameters of the target cable and the environmental parameters when the target cable is iced, and utilizing... Figure 3 The icing parameters calculated by the process shown are shown in Table 1 below:

[0176] Table 1

[0177]

[0178] As shown in Table 1 above, the average icing density (i.e., the preset density) of the target wire set by the technicians is 0.6 tons / m. 3 Based on this, according to Figure 3 The target wire thickness calculated by the process shown is 20.11 mm, and the standard thickness under standard icing density is 15.087 mm.

[0179] Then, using the above data, the wind deflection angle of the target wire suspension can be deduced to be 6.856°.

[0180] Continue by applying items 1-13 in Table 1 and item 14 in Table 2 below (that is, assuming the wind deflection angle of the target wire suspension is 6.856°), according to... Figure 4 The process shown calculates the icing parameters of the target wire in an icing environment, resulting in the information in Table 2 below:

[0181] Table 2

[0182]

[0183] As shown in Table 2 above, the calculated actual icing thickness (i.e., average icing thickness), average density (i.e., actual icing density), and standard icing thickness values ​​for the target wire are consistent with those obtained according to... Figure 3 The icing parameters calculated by the process shown are consistent.

[0184] Therefore, the above Figure 3 and Figure 4 The icing parameters of the target wire measured by the process shown are consistent under icing conditions.

[0185] See Figure 5 This is a flowchart illustrating another embodiment of the method for measuring wire icing provided by this invention. Figure 5 As shown, the process may include the following:

[0186] First, set the target wire. Specifically, you can choose a tensile testing instrument, an anemometer, or other mounting accessories that can transmit measurement results, such as a temperature sensor, a fixing point for suspending the target wire, and a suspension wire. Simultaneously, select the diameter of the round wire used as the sample. and length In addition to other required properties (such as initial gravity).

[0187] Next, the sample cable (target cable) is horizontally installed at the location where the icing thickness needs to be measured, i.e., the icing environment, and the azimuth angle of the sample cable installation and the altitude of that location are obtained. This altitude can be the actual altitude of the wire in this icy environment.

[0188] Next, the initial weight of the sample wire was measured under windless and ice-free conditions. And calibrate the tensile force measuring device.

[0189] Optionally, when the sample wire becomes icy, the total weight of the sample wire after icing plus the weight of the icing can be obtained. Wind speed V, and the angle between the wind direction and the axis of the sample wire. .

[0190] Next, determine whether there is a wind deflection measuring device for suspending the sample wire and whether there is a certain wind speed.

[0191] Optionally, if there is no wind deflection measuring device for suspending the sample wire and there is wind, the ice density set by the technician can be obtained, and the equations in equation (I) above can be solved to obtain the corresponding ice thickness of the wire. And the ice thickness (standard thickness) of the standard ice density of the sample wires is calculated in real time during operation. .

[0192] Conversely, if a device for measuring the wind deflection angle of the suspended sample wire is available, and a certain wind speed is present, the angle between the suspended wire and the vertical line to the ground can be obtained. And calculate the vertical component of the force on the suspension wire. Then, by solving the system of equations in equation (III) above, the icing thickness of the sample wire under actual conditions is obtained. Then calculate the actual average density of icing on the sample wire. This allows for the estimation of icing characteristics based on the average density. Simultaneously, the icing thickness of the sample wire, converted to the standard ice density, can also be calculated. .

[0193] The technical solution provided by this invention determines different methods for determining icing parameters based on whether there is a wind deflection measuring device for suspending the sample wire and a certain wind speed. This allows for accurate, simple, and efficient measurement of the icing parameters of the target wire, which in turn determines the severity of icing. Consequently, appropriate anti-icing, anti-icing, and de-icing measures can be taken in a timely and accurate manner.
