Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for determining windage conditions of a conductor, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than presented herein.
Fig. 1 is a flow chart of a method for determining windage yaw of a conductor according to an embodiment of the invention. As shown in fig. 1, the method may include the steps of:
and S102, acquiring the sag of the target position and the wind deflection angle of the wire.
In the technical solution provided by step S102 of the present invention, the target position may be any position on the wire, and the sag of the target position on the wire and the wind deflection angle of the wire may be obtained through the three-dimensional laser point cloud model.
Optionally, the sag generally refers to a vertical distance between a lowest point of a wire and a connecting line between two suspension points when the suspension heights of the wires on two adjacent base electric poles are the same on a flat ground, and when the transmission distance is longer, a slight sag is formed due to the self weight of the wires, so that the wires are in a shape of a catenary. The sag in the embodiment can refer to the vertical distance between any point on the lead and a connecting line between suspension points when the suspension heights of two end points of the lead on two adjacent base electric poles are different on a flat ground.
Optionally, the wind deflection angle generally refers to an included angle formed by the overhead transmission line and a vertical position of the overhead transmission line when the overhead transmission line deviates from the vertical position under the action of wind force.
And step S104, determining a target distance between the target position and the target object based on the sag and the yaw angle.
In the technical solution provided in step S104 of the present invention, after the sag and the windage yaw angle are obtained, geometric operation may be performed on the sag and the windage yaw angle, so as to determine a target distance between a target position on the wire and a target object under the action of wind.
Alternatively, the target distance in this embodiment may be the perpendicular distance between the target location on the wire and the target object.
Alternatively, the target object in this embodiment may include the ground, trees, houses, slopes, adjacent pylons, adjacent wires, and the like.
And step S106, determining the windage yaw position of the wire based on the target distance.
In the technical solution provided in step S106 of the present invention, after the target distance between the target position on the wire and the target object is determined, the windage yaw position of the wire under the action of wind force can be determined according to the target distance through the three-dimensional laser point cloud model, and the windage yaw position can be used to represent the distance of the wire from the original position.
Through the steps S102 to S106, the sag of the target position and the wind deflection angle of the wire are obtained; determining a target distance between the target position and the target object based on the sag and the yaw angle; a windage yaw position of the wire is determined based on the target distance. That is to say, the embodiment determines the target distance between the wire and the target object through the sag of any point on the wire of the power transmission line and the wind deflection angle of the wire, and because the target distance is the position behind the wind deflection of the wire, the wind deflection position of the wire can be determined based on the target distance, thereby solving the technical problem of low accuracy in determining the wind deflection position of the wire, and achieving the technical effect of improving the accuracy in determining the wind deflection position of the wire.
The above-described method of this embodiment is further described below.
As an alternative implementation, step S102, acquiring the sag of the target position of the wire, includes: acquiring a first horizontal distance and a first vertical distance between a target position and one end of a wire; acquiring a second horizontal distance and a second vertical distance between the target position and the other end of the wire; acquiring a first difference between the first vertical distance and the second vertical distance, and acquiring a first product between the first difference and the second horizontal distance; acquiring a first sum between the first horizontal distance and the second horizontal distance, and acquiring a first quotient between the first product and the first sum; determining the sag based on the second vertical distance and the first quotient.
In this embodiment, when the sag of the target position on the wire is obtained through the three-dimensional laser point cloud model, the horizontal distance and the vertical distance between the target position and the two end points of the wire may be obtained first, and then the sag of any point on the wire may be obtained by performing mathematical operation on the horizontal distance and the vertical distance.
Alternatively, the end point of the wire in this embodiment may also be referred to as a suspension point.
Alternatively, the elevation of one end of the wire may be greater than the elevation of the other end of the wire in this embodiment.
Alternatively, the embodiment may use three-dimensional analysis software to measure the horizontal distance and the vertical distance between any one position on the wire and the suspension points on both sides of the wire.
As an alternative embodiment, determining the sag based on the second vertical distance and the first quotient includes: acquiring a second sum between the second vertical distance and the first quotient under the condition that the elevation values of the two ends of the lead are both larger than the elevation value of the target position; the second sum is determined as sag.
In this embodiment, in the case that the elevation values of the suspension points on both sides of the wire are both greater than the elevation value of the target position on the wire, the sag of the target position may be calculated by the following formula:
Figure BDA0002793721300000051
wherein HOCA sag that can be used to represent a target location; xAMay be used to represent a first horizontal distance; xBMay be used to represent a second horizontal distance; h isAMay be used to represent a first vertical distance; h isBMay be used to represent the second vertical distance.
As an alternative embodiment, determining the sag based on the second vertical distance and the first quotient includes: acquiring a second difference between the first quotient and a second vertical distance under the condition that the elevation value of one end of the lead is greater than that of the target position and the elevation value of the target position is greater than that of the other end of the lead; the second difference is determined as sag.
In this embodiment, when the elevation value of one end of the wire is greater than the elevation value of the target position, and the elevation value of the target position is greater than the elevation value of the other end of the wire, that is, the elevation value of the target position is located between the elevation values of the suspension points on both sides of the wire, the sag of the target position may be calculated by the following formula:
Figure BDA0002793721300000052
optionally, the embodiment may write a program in MATLAB based on the above two formulas, so that after inputting the horizontal distance and the vertical distance between any one position on the wire and the suspension points on both sides of the wire, the sag of the position on the wire may be automatically obtained.
As an alternative embodiment, obtaining the wind deflection angle of the wire includes: acquiring the line weight of the wind load and the wire, and determining a second quotient between the wind load and the line weight; based on the second quotient, a wind deflection angle is determined.
In this embodiment, when obtaining the wind deflection angle of the wire, the wind load of the wind power received by the wire and the line weight (dead weight) of the wire may be obtained first, then the quotient of the wind load and the line weight is redone, after obtaining the quotient of the wind load and the line weight, the angle of the wind deflection angle may be obtained by using a trigonometric function, and the trigonometric function value of the wind deflection angle may be calculated by the following formula:
Figure BDA0002793721300000061
where θ may be used to represent the angle of the wind deflection angle; wFMay be used to represent wind load; wDMay be used to represent the wire weight of the wire.
In the above embodiment, after the trigonometric function value of the wind deflection angle is obtained, the angle value of the wind deflection angle can be determined according to the obtained trigonometric function value.
Alternatively, in this embodiment, the wind load may be calculated by the following formula:
WF＝α·W0·μz·μSC·βc·l·D·sin2β
wherein, alpha can be used for representing the wind pressure uneven coefficient; w0Can be used to express the reference wind load, and the calculation formula can be: where v may be used to represent wind speed; mu.szThe method can be used for representing the wind pressure height change coefficient; mu.sSCCan be used to represent wire form factor; beta is aCCan be used to represent the wire wind load adjustment coefficient; l can be used for representing the horizontal span of the tower; d may be used to represent the wire outer diameter; beta may be used to denote the angle of the wind direction to the wire direction.
Optionally, in this embodiment, the wind pressure height variation coefficient may be 1.56, the conductor form coefficient may be 1.2 when the outer diameter of the conductor is less than 17mm, 1.1 when the outer diameter of the conductor is greater than or equal to 17mm, and the conductor wind load adjustment coefficient may be 1.
Optionally, in this embodiment, because the wind speeds are different, values of the uneven wind pressure coefficients may also be different, so that when the wind speed of the environment where the wire is located changes, the wind deflection angle of the wire at different wind speeds can be calculated through different uneven wind pressure coefficients, and the values of the uneven wind pressure coefficients can be shown in table 1:
TABLE 1 wind pressure uneven coefficient value-taking table
Wind speed v (m/s) <20 20-27 ≥27-31.5
Α 1 0.75 0.61
Alternatively, in this embodiment, the wire weight of the wire may be calculated by the following formula:
WD＝m·l·g
where m may be used to represent the mass per unit length of wire; l can be used for representing the horizontal span of the tower; g may be used to represent gravitational acceleration.
As an optional embodiment, before determining the target distance between the target position and the target object based on the sag and the yaw angle, the method further comprises: in the case where the wind speed is zero, a third vertical distance between the target position and the target object is acquired.
In this embodiment, in order to determine the windage yaw position of the target position on the wire under the action of the wind force, it is necessary to first determine an original position where the target position on the wire is located under the condition that the wind force is zero, and use the original position as a reference position, so as to determine the windage yaw position of the target position on the wire relative to the original position under the action of the wind force, where the third vertical distance may be used to indicate the original position where the target position on the wire is located under the condition that the wind force is zero.
As an alternative embodiment, determining the windage yaw position of the conductor based on the target distance includes: acquiring a third difference between the target distance and a third vertical distance; a windage yaw position is determined based on the third difference.
In this embodiment, when the wind speed is determined to be zero, after the third vertical distance between the target position and the target object is determined, the difference between the third vertical distance and the target distance may be determined through a three-dimensional laser point cloud model, so that, according to the obtained difference, the distance that the target position on the wire deviates from the original position thereof when the wire is subjected to the wind force is determined, and according to the distance, the windage yaw position of the target position on the wire is determined, which may be used to indicate the distance that the target position on the wire deviates from the original position thereof when the wire is subjected to the wind force.
Optionally, the embodiment may utilize three-dimensional point cloud analysis software to determine the position relationship between the target position on the wire and the target object, so as to calculate and analyze the safe distance between the target position on the wire and the target object after windage yaw at different wind speeds of the wire.
Optionally, the embodiment may utilize a three-dimensional laser scanner to perform three-dimensional reconstruction on the power transmission line, so as to obtain a three-dimensional point cloud model of the power transmission line, accurately reduce the three-dimensional structure and size of the power transmission line, and further simulate the line operation condition through windage yaw calculation.
In the related art, when the windage yaw position of the line is calculated, the windage yaw position of the line is calculated based on infrastructure design parameters of the power transmission line, and because the related art does not consider the actual operation condition of the power transmission line and is only used for simple electrical distance measurement, the calculated windage yaw position of the line has large deviation from the actual condition, and the problem of inaccurate calculation of the windage yaw position of the actual lead occurs.
According to the method for determining the windage yaw position of the wire, the target distance between the wire and the target object is determined through the sag of any point on the wire of the power transmission line and the windage yaw angle of the wire, and the target distance is the position behind the windage yaw of the wire, so that the windage yaw position of the wire can be determined based on the target distance, the technical problem of low accuracy of determining the windage yaw position of the wire is solved, and the technical effect of improving the accuracy of determining the windage yaw position of the wire is achieved.
