[0002] The power system is an electricity production and consumption system composed of power generation, transmission, transformation, distribution and power consumption. It converts primary energy in nature into electricity through mechanical energy devices, and then supplies electricity to various users through transmission, transformation and distribution. However, in the process of power transmission, transmission lines are prone to conductor dancing. Conductor dancing is a low-frequency, large-amplitude self-excited vibration phenomenon caused by uneven ice coverage along the circumference of overhead wires under the action of lateral wind force. Once the transmission line dances with a large amplitude, it is easy to cause phase-to-phase flashover, causing line tripping and power outage, which brings great harm to the safe operation of the power grid.
[0003] The existing technology for monitoring the galloping of transmission line conductors is to install a wire clamp at a specified position of the conductor, install a displacement sensor on one side of the wire clamp, and install a vibration sensor at a specified distance from the outlet on the other side of the conductor, and use the bending amplitude method to measure the dynamic bending strain of the conductor. However, the current conductor galloping monitoring method uses a contact measurement method, which is easy to interfere with or affect the measured conductor, and the measurement range is limited, and it is impossible to perform large-scale conductor galloping monitoring;
[0004] To this end, the present invention proposes an intelligent monitoring method for transmission line conductor dancing based on radar technology. Summary of the invention

[0016] Step S22, then obtaining the dancing amplitude of the conductor segment in the transmission line each time it dances, traversing and comparing the dancing amplitudes each time it dances, obtaining the maximum value of the dancing amplitude and recording it as the dancing amplitude upper limit FDi;
[0017] Step S23, finally obtaining the number of times the conductor segment in the transmission line faces the wind YFi and the wind force at each time, and adding and averaging the wind force at each time to obtain the wind force FLi of the conductor segment in the transmission line;
[0018] Step S24, combining the conductor length CDi of the conductor segment in the transmission line, the dancing monitoring value WJi of the conductor segment in the transmission line is calculated by a formula, and the specific formula is as follows:
[0019] WJi=[(WCi+YFi)×a1+FDi×a2+FLi×a3+CDi×a4]×LVi; where a1, a2, a3 and a4 are weight coefficients;

[0054] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0055] Example 1: Please refer to Figure 1-Figure 5 As shown, the technical solution provided by the present invention is: an intelligent monitoring method for the dancing of transmission line conductors based on radar technology, the method is specifically as follows:
[0056] First, the transmission line is divided into conductor segments through transmission towers;
[0057] Step S1, obtaining historical dancing data of different conductor segments in the transmission line and historical environmental data of the area where the conductor segments are located;
[0058] It should be specifically explained that the historical dancing data is the dancing failure rate, the number of dancing times and the dancing amplitude of each dancing of the wire segment within the historical time period, wherein the historical time period includes but is not limited to the previous week, the previous month, the previous quarter or the previous year. In order to avoid a large number and a large data time span, in this embodiment, the preferred historical time period is the previous week. The dancing failure rate is obtained by dividing the number of power failures caused by the dancing of the wire segment by the number of historical dancing times. The dancing failure rate can be zero. The dancing amplitude is the deviation angle of the wire segment when it dances. The deviation angle is the angle between the surface where the wire segment is in a static state and the surface where the wire segment is when it dances. The deviation angle is the degree of the deviation angle, such as Figure 2 As shown, in the static state, the plane formed by the conductor segment is AB. When the conductor segment dances westward, the plane formed by the conductor segment is A1-B1. The plane AB and the plane A1-B1 form an angle α, and α is the deviation angle.
[0059] The historical environmental data includes the number of times the conductor segment faces the wind during the historical period and the wind force each time it faces the wind. If the conductor segment is in a south-north direction and the wind direction is in an east-west direction, that is, the direction of the conductor segment is not exactly the same as the wind direction, the wind direction at this time will cause the conductor segment to dance, and the number of times it faces the wind is recorded. If the conductor segment and the wind direction are exactly the same, the wind direction at this time will not cause the conductor segment to dance, and the number of times it faces the wind is not recorded.
[0060] Step S2, obtaining the conductor length of the conductor segment in the transmission line, and establishing a measurement and control standard for the conductor segment based on historical dancing data and historical environmental data;
[0061] In this embodiment, step S2 includes the following sub-steps:
[0062] Step S21, obtaining the galloping fault rate LVi and the galloping number WCi of the conductor segment in the transmission line, where i is the number of the conductor segment;
[0063] Step S22, then obtaining the dancing amplitude of the conductor segment in the transmission line each time it dances, traversing and comparing the dancing amplitudes each time it dances, obtaining the maximum value of the dancing amplitude and recording it as the dancing amplitude upper limit FDi;
[0064] Step S23, finally obtaining the number of times the conductor segment in the transmission line faces the wind YFi and the wind force at each time, and adding and averaging the wind force at each time to obtain the wind force FLi of the conductor segment in the transmission line;
[0065] Step S24, combining the conductor length CDi of the conductor segment in the transmission line, the dancing monitoring value WJi of the conductor segment in the transmission line is calculated by a formula, and the specific formula is as follows:
[0066] WJi=[(WCi+YFi)×a1+FDi×a2+FLi×a3+CDi×a4]×LVi; where a1, a2, a3 and a4 are weight coefficients, and a1>a2>a3>a4 is defined;
[0067] Step S25, obtaining the measurement and control standard of the conductor segment in the transmission line according to the dancing monitoring value, specifically:
[0068] If WJi∈[Y1, Y2), the conductor segment in the transmission line implements the third measurement and control standard;
[0069] If WJi∈[Y2, Y3), the conductor segment in the transmission line implements the second measurement and control standard;
[0070] If WJi∈[Y3, +∞), the conductor segment in the transmission line implements the first measurement and control standard; where 0<Y1<Y2<Y3;
[0071] Among them, the measurement and control standards cover the number of measurement and control points when measuring and controlling the conductor segment, the measurement and control intensity of the first measurement and control standard is higher than the measurement and control intensity of the second measurement and control standard, the measurement and control intensity of the second measurement and control standard is higher than the measurement and control intensity of the third measurement and control standard, the number of measurement and control points corresponding to the first measurement and control standard is more than the number of measurement and control points corresponding to the second measurement and control standard, the number of measurement and control points corresponding to the second measurement and control standard is more than the number of measurement and control points corresponding to the third measurement and control standard, and the corresponding number of test points on the conductor segment is at least two groups;
[0072] In practice, the measurement and control standard may also cover the number of measurement and control times of the conductor segment. Therefore, the number of measurement and control times corresponding to the first measurement and control standard is greater than that corresponding to the second measurement and control standard, and the number of measurement and control times corresponding to the second measurement and control standard is greater than that corresponding to the third measurement and control standard.
[0073] Step S3, monitoring the dancing of the conductor segments in the transmission line according to the corresponding measurement and control standards, and installing corresponding measurement and control equipment;
[0074] Specifically, Figure 3 As shown, the measurement and control equipment is specifically a millimeter-wave radar, which includes a signal transceiver, wherein the signal transceiver has signal receiving and signal receiving functions, the reflector is installed at the measurement and control point on the wire segment, and the signal transceiver is placed directly below the measurement and control point. At the same time, the signal transceiver has a reflector tracking function, that is, when the reflector moves, the signal transceiver can adjust the angle of signal reception and transmission by itself.
[0075] Step S4, collecting real-time dancing data of the conductor segment based on the measurement and control equipment, and analyzing the dancing degree of the conductor segment on the transmission line according to the real-time dancing data;
[0076] Among them, Figure 4As shown, the real-time dancing data is the real-time adjustment angle of the signal transceiver corresponding to the wire segment, and the real-time interval distance between the signal transceiver and the reflector. The real-time interval distance can be calculated by the signal rate and the transmission and reception time.
[0077] In this embodiment, step S4 includes the following sub-steps:
[0078] Step S41, obtaining the initial spacing distance CJio between the reflector and the signal transceiver at the measurement and control point on the conductor segment in a static state, where o is the number of the measurement and control point;
[0079] Step S42, then obtaining the real-time distance SJio between the reflector and the signal transceiver at the measurement and control point on the conductor segment;
[0080] Step S43: if the real-time interval distances between the reflector and the signal transceiver at all the measurement and control points on the conductor segment are equal to the corresponding initial interval distances, no operation is performed;
[0081] Step S44, if the real-time interval distance between the reflector and the signal transceiver at any measurement and control point on the conductor segment is not equal to the corresponding initial interval distance, the distance fluctuation value BDio of the reflector at the corresponding measurement and control point on the conductor segment is obtained by subtracting the initial interval distance from the real-time interval distance; when there is only one measurement and control point where the real-time interval distance between the reflector and the signal transceiver is not equal to the corresponding initial interval distance, the distance fluctuation value of the reflector at the corresponding measurement and control point on the conductor segment is used as the distance abnormality value JLYi of the conductor segment; when there are multiple measurement and control points where the real-time interval distance between the reflector and the signal transceiver is not equal to the corresponding initial interval distance, the distance fluctuation values are traversed and compared to obtain the maximum value and used as the distance abnormality value JLYi of the conductor segment;
[0082] Step S45, similarly, when there is only one measurement and control point where the real-time interval distance between the reflector and the signal transceiver is not equal to the corresponding initial interval distance, the real-time adjustment angle of the signal transceiver corresponding to the reflector at the measurement and control point is obtained as the angle abnormal value JDYi of the conductor segment; when there are multiple measurement and control points where the real-time interval distance between the reflector and the signal transceiver is not equal to the corresponding initial interval distance, the real-time adjustment angles of the signal transceivers corresponding to the reflectors at different measurement and control points are traversed and compared to obtain the maximum value of the real-time adjustment angle as the angle abnormal value JDYi of the conductor segment;
[0083] Step S46, substitute the distance abnormal value and the angle abnormal value into the calculation formula WYi=JDYi×b1+JLYi×b2 to calculate the galloping abnormal value WYi of the conductor segment in the transmission line; in the formula, b1 and b2 are both weight coefficients;
[0084] Step S47, if the dancing abnormality value is less than or equal to the first dancing abnormality threshold, the dancing degree of the wire segment is slight dancing;
[0085] If the dancing abnormality value is greater than the first dancing abnormality threshold and less than or equal to the second dancing abnormality threshold, the dancing degree of the wire segment is moderate dancing;
[0086] If the dancing abnormality value is greater than the second dancing abnormality threshold value, and the first dancing abnormality threshold value is less than the second dancing abnormality threshold value, then the dancing degree of the wire segment is severe dancing.
[0087] Step S5, executing a management method for the conductor segment in the transmission line in combination with the dancing degree;
[0088] Specifically, step S5 includes the following sub-steps:
[0089] Step S51, if the dancing degree of the wire segment is slight dancing, the wire segment is monitored daily to prevent the dancing degree from getting worse;
[0090] Step S52, if the dancing degree of the conductor segment is moderate dancing, applying an anti-dancing device to the conductor segment at a large spacing;
[0091] Step S53, if the dancing degree of the wire segment is severe dancing, an anti-dancing device is applied to the wire segment at a small spacing;
[0092] Among them, the anti-dancing devices include but are not limited to line-installed wire clamps, rotary spacers, phase spacers, and double-swing anti-dancing devices.
[0093] Due to the adoption of the technical solution of this embodiment, based on the historical dancing data of different conductor segments in the transmission line and the historical environmental data of the area where the conductor segments are located, and then combined with the conductor length of the conductor segments in the transmission line, a measurement and control standard adapted to the conductor segments in the transmission line is established;
[0094] At the same time, when this embodiment monitors the dancing of the conductor segment in the transmission line according to the adapted measurement and control standard, the real-time dancing data of the conductor segment is collected through the measurement and control equipment, and the dancing degree of the conductor segment on the transmission line is analyzed based on the real-time dancing data, and finally the management method of the conductor segment in the transmission line is implemented in combination with the dancing degree.

The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.
