Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transmission tower monitoring, more particularly, it relates to a transmission tower tilt real-time monitoring method and system under complex wind field action. BACKGROUND

[0002] Transmission tower tilt is mainly caused by tower site loose soil and adverse weather factors, resulting in overall tilt of the tower or partial structure deformation tilt. Since the transmission tower is located at a high position of the power transmission line, under adverse natural environments such as typhoon, sandstorm, and rainstorm, the upper end of the transmission tower is prone to large amplitude shaking. The transmission towers at both ends of the power transmission line are prone to cause power transmission line breakage during large amplitude shaking. The power transmission line is more prone to breakage after the transmission tower tilts. Therefore, monitoring the state of the transmission tower is beneficial to timely maintenance and emergency disposal for ensuring safe operation of the transmission tower.

[0003] At present, for the transmission tower tilt caused by static environment, such as the transmission tower tilt caused by tower site loose soil, the tilt state of the transmission tower can be monitored by a tilt angle sensor. However, for the transmission tower tilt caused by dynamic environment, such as typhoon, sandstorm, and rainstorm, the transmission tower will shake under the action of the wind field. The tilt angle and tilt direction are different under the influence of different wind fields. Therefore, the tilt state of the transmission tower cannot be directly judged by the angle value collected by the tilt angle sensor, whether it is self-tilt or wind-induced vibration.

[0004] Therefore, how to research and design a transmission tower tilt real-time monitoring method and system capable of overcoming the above defects is a problem that needs to be solved at present. SUMMARY

[0054] In order to make the purpose, technical scheme and advantages of the application more clear and explicit, the application is further described in detail below in combination with the embodiments and drawings, and the illustrative embodiments of the application and the description thereof are only used to explain the application, and do not constitute a limitation on the application.

[0055] Embodiment 1: A power transmission tower tilt real-time monitoring method under the action of complex wind field, as shown in Figure 1 includes the following steps:

[0056] S1: Establish a three-dimensional coordinate system with the target tower as the origin, and establish a fitting function between each axial vibration component and the corresponding axial wind speed component according to the historical vibration data of the target tower under the action of different wind speeds;

[0057] S2: Collect real-time vibration data in the current monitoring period, and select a plurality of vibration sections with stable wind speed from the real-time vibration data, and determine the stable wind speed of each vibration section;

[0058] S3: Select two vibration sections with the highest difference priority value from the plurality of vibration sections as the first section and the second section;

[0059] S4: Calculate the theoretical vibration deviation of the corresponding axial according to the fitting function of each axial and the stable wind speed of the first section and the second section;

[0060] S5: Determine the actual vibration deviation of the corresponding axial according to the real-time vibration data corresponding to the first section and the second section;

[0061] S6: Perform logical judgment on the actual vibration deviation of each axial and the theoretical vibration deviation of each axial, and if there is a case that the actual vibration deviation does not conform to the judgment logic of the theoretical vibration deviation, output an early warning signal indicating that the target tower is in tilt deformation.

[0062] It should be noted that the historical vibration data can be measured by a vibration sensor to measure the vibration amplitude, and then the maximum vibration amplitude is selected as the historical vibration data; in addition, an acceleration sensor can also be used to measure the vibration acceleration.

[0063] The establishment process of the fitting function is as follows: decompose the wind speed acting on the target tower into axial wind speed components in the three-dimensional coordinate system; extract the axial vibration components in the three-dimensional coordinate system from the historical vibration data; and fit the axial vibration components and the corresponding axial wind speed components to obtain a fitting function with the axial wind speed component as the abscissa and the axial vibration component as the ordinate.

[0064] It should be noted that the fitting function can be a linear function or a nonlinear function, for example, a curve function fitting using the least square method.

[0065] If the wind speed changes quickly, different wind speed actions need to overcome the previous vibration, so as to ensure the accuracy and reliability of monitoring, the section with relatively slow wind speed change needs to be selected. In the embodiment, the wind speed in the vibration section is in a stable state, and the determination process is as follows: the wind speed size and the axial angle of each axis contained in the stable wind speed in the vibration section are extracted; the maximum allowable wind speed deviation in different axes is calculated by combining the preset maximum wind speed deviation angle, the wind speed size and the axial angle; the actual maximum wind speed deviation in different axes in the vibration section is obtained, and if the actual maximum wind speed deviation in each axis does not exceed the maximum allowable wind speed deviation in the corresponding axis, the wind speed in the corresponding vibration section is in a stable state.

[0066] In the determination process of whether the wind speed in the vibration section is in a stable state, the influence of the full-range fluctuation of the wind speed in the three-dimensional coordinate system on the fluctuation of the single-axis wind speed component is comprehensively considered, and the actual maximum wind speed deviation in different axes is compared with the maximum allowable wind speed deviation in different axes, so that whether the wind speed in the vibration section is in a stable state can be quickly judged, and the identification and judgment efficiency is high.

[0067] In the embodiment, the determination process of the stable wind speed in the vibration section is as follows: the average value of the wind speed size of the full-section wind speed in the vibration section is taken as the wind speed size of the corresponding stable wind speed; and the average value of the axial angle of the full-section wind speed in the same axis in the vibration section is taken as the axial angle of the corresponding stable wind speed in the corresponding axis.

[0068] As shown in Figure 2 , it is assumed that the preset maximum wind speed deviation angle is a, the stable wind speed in the vibration section m is v m , and the axial angle of the axis i is Then the wind speed size is |v m |; the angle degree of the two limit cases of the maximum vibration deviation allowed in a single axis is 2a, and the maximum vibration deviation is the projection distance of 2a in the axis.

[0069] Therefore, the projection distance TY is:

[0070] After simplification, the calculation formula of the maximum allowable wind speed deviation is as follows:

[0071]

[0072] Wherein, represents the maximum allowable wind speed deviation in the axis i in the vibration section m; |v m | represents the wind speed size of the stable wind speed in the vibration section m; represents the axial angle of the stable wind speed in the vibration section m and the axis i; a represents the preset maximum wind speed deviation angle.

[0073] In the embodiment, the calculation formula of the difference priority value is specifically as follows:

[0074]

[0075]

[0076]

[0077] wherein, represents the difference priority value between the vibration section n1 and the vibration section n2; δ1 represents the priority value determined by the angle difference; k1 represents the weight coefficient corresponding to the angle difference; δ2 represents the priority value determined by the wind speed difference; k2 represents the weight coefficient corresponding to the wind speed difference; and β represents the spatial included angle of the two vibration sections in the three-dimensional coordinate system. represents the wind speed of the steady wind speed in the vibration section n1. represents the wind speed of the steady wind speed in the vibration section n2.

[0078] The present application considers the influence of the angle difference and the wind speed difference on the vibration deviation when screening the first section and the second section, and selects the two sections with smaller wind speed difference and close to 90° angle difference as the first section and the second section as far as possible, so as to ensure the calculation accuracy of the theoretical vibration deviation and the actual vibration deviation, thereby improving the accuracy and reliability of the tilt deformation monitoring.

[0079] It should be noted that the difference priority value can also consider the angle difference or the wind speed difference alone, which is not limited herein. In addition, the specific calculation method of the priority value determined by the angle difference and the wind speed difference is not limited to the above method, for example, other functions with consistent positive and negative correlation can also be added.

[0080] In addition, the expression of the logical judgment is specifically as follows:

[0081]

[0082] wherein, represents the theoretical vibration deviation of the first section and the second section in the axial i, which is calculated by the absolute value of the difference between the two theoretical axial vibration components calculated by combining the fitting function with the axial wind speed components of the two sections; and L i，w represents the allowed vibration error in the axial i. represents the actual vibration deviation of the first section and the second section in the axial i, which is calculated by the absolute value of the difference between the actual axial vibration components of the two sections.

[0083] It should be noted that the vibration error allowed in the axial direction can be adaptively adjusted according to the sensitivity of monitoring, and the vibration error corresponding to the upper limit value and the lower limit value can be different.

[0084] Embodiment 2: A power transmission tower tilt real-time monitoring system under the action of a complex wind field, which is used to realize the power transmission tower tilt real-time monitoring method under the action of a complex wind field as recorded in Embodiment 1, as shown in the figure, comprising a function fitting module, a stationary analysis module, a section screening module, a theoretical calculation module, an actual analysis module and a logical judgment module. Figure 3

[0086] Working principle: The actual vibration difference and the turn-by-turn vibration difference of the power transmission tower under the action of different wind speeds are analyzed, and then the actual vibration difference and the turn-by-turn vibration difference are compared to judge whether the power transmission tower is in a tilt state caused by its own structural deformation or damage. When the power transmission tower is in a dynamic change tilt state after being acted on by two different wind speeds, it can also be accurately monitored, and real-time early warning can be performed when the power transmission tower is in a wind-induced vibration process.
