Description

Technical Field

[0001] The present invention relates to the technical field of overhead cables, and in particular to an intelligent assessment system for galloping risks of overhead cables. Background Art

[0002] The dangers of overhead cable galloping are significant. Repeated bending can cause metal fatigue and shorten service life, potentially leading to cable breakage and tower collapse, disrupting the normal supply of electricity and communications. Furthermore, the dynamic tension generated by galloping can damage hardware, insulators, and other equipment, posing a serious threat to public safety and social stability.

[0003] The invention patent with application number 202010984547.5 discloses a method for detecting the dancing of a transmission line cable, which includes: using a transmission line cable dancing detection device to calculate the maximum sag of the cable. The measured value of the dancing detection module can calculate the angle between the three directions of x, y, and z axes relative to the direction of gravity, that is, the angle of gravity when the transmission line is dancing is detected. The tangent slope of the transmission line at the device is obtained through this angle, and the y-axis in the coordinate system is the direction of gravity; the transmission line cable dancing detection device is characterized in that it includes: an external Shell, power supply module, main control circuit board, dancing detection module, communication transmission module; the power supply module, main control circuit board, dancing detection module and communication transmission module are arranged in the shell; the shell is provided with a shell upper frame, a shell bottom frame and an isolation pad, and the middle part of the lower end of the shell upper frame and the middle part of the upper end of the shell bottom frame are both provided with cable grooves; the shell upper frame and the shell bottom frame tightly lock the tested cable in the cable groove through the isolation pad; the shell upper frame and the shell bottom frame are respectively sealed by the upper frame cover and the bottom frame cover; the power supply module is electrically connected to the main control circuit board, the dancing detection module and the communication transmission module respectively.

[0004] The application aims to solve the problem that "with the expansion of my country's power grid and the frequent occurrence of large-scale extreme weather, the probability of transmission line galloping accidents has increased significantly. In order to improve the power grid's ability to resist natural disasters and ensure that the power grid can operate safely and stably and provide reliable power supply under severe natural conditions, it becomes extremely important to carry out research on the transmission line galloping mechanism, sag detection methods and anti-galloping measures."

[0005] However, currently, most of the overhead cable galloping monitoring is based on collected digital data for risk monitoring, and most of them do not have visualization conditions;

[0006] To this end, we propose an intelligent assessment system for the galloping risk of overhead cables. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the prior art, the present invention provides an intelligent assessment system for the galloping risk of overhead cables, which solves the technical problems raised in the above-mentioned background technology.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] An intelligent assessment system for the galloping risk of overhead cables, comprising:

[0010] A monitoring module is used to monitor the dancing information of overhead cables in real time; a construction module is used to receive the dancing information of overhead cables monitored by the monitoring module and to construct an overhead cable dancing model based on the overhead cable dancing information; a creation module is used to create a safe space for the overhead cable dancing model; a rendering module is used to obtain the overhead cable dancing model constructed in the construction module and the safe space for the overhead cable dancing model created in the creation module, and to render the overhead cable dancing model and the safe space for the overhead cable dancing model; an evaluation module is used to receive the overhead cable dancing model and the safe space for the overhead cable dancing model rendered in the rendering module, and to evaluate whether the overhead cables are safe and the dynamic trend of risks based on the rendered overhead cable dancing model and the safe space for the overhead cable dancing model; an output module is used to obtain the evaluation results of whether the overhead cables are safe and the dynamic trend of risks in the evaluation module, and to output the evaluation results.

[0011] Furthermore, the monitoring module is provided with submodules at the lower level, including:

[0012] Positioning unit, used to locate the position information of overhead cables in real time;

[0013] a storage unit, configured to receive the position information of the overhead cable located by the positioning unit and store the position information of the overhead cable;

[0014] Wherein, the positioning unit is integrated by position sensors, and there are no less than two groups of position sensors. The position sensors are all deployed on the surface of the overhead cable, and one group of the position sensors is deployed at the midpoint of the monitored target overhead cable. The position sensors are deployed equidistantly on the surface of the overhead cable, and the position sensors are deployed on one side of the overhead cable based on the midpoint of the overhead cable. The system end user of the positioning unit defines an operating cycle, and the positioning unit continuously operates based on the operating cycle to locate the position information of the overhead cable. The storage unit runs synchronously with the positioning unit, and the overhead cable position information is distinguished and stored based on the positioning timestamp of the overhead cable position information.

[0015] Furthermore, the number of position sensors of the positioning unit is determined by: the higher the safety requirement of the overhead cable, the longer the length of the overhead cable, the larger the diameter of the overhead cable, and the more frequent the bad weather in the area where the overhead cable is located, the more position sensors are set, and vice versa.

[0016] The distance between the position sensor deployed at the midpoint of the overhead cable and the farthest group of position sensors deployed on the overhead cable follows the following rules: the higher the safety requirements of the overhead cable, the longer the length of the overhead cable, the larger the diameter of the overhead cable, the more frequent the severe weather in the area where the overhead cable is located, and the higher the accuracy requirements for dancing monitoring, the farther the distance between the two groups of position sensors, and vice versa, the closer the distance between the two groups of position sensors.

[0017] Furthermore, the overhead cable galloping information received by the construction module is derived from a storage unit of a lower submodule of the monitoring module. The construction module continuously receives and distinguishes the stored overhead cable position information in the storage unit based on a time sequence, and constructs the overhead cable galloping model based on the continuously received overhead cable position information.

[0018] The logic of the building module to construct the overhead cable galloping model is:

[0019] The construction module operates based on a time sequence from early to late to receive a set of overhead cable position information in the divided intervals each time, connects the overhead cable position information in the divided intervals adjacent to each other, and obtains a set of multi-segment line models;

[0020] When setting a construction module to construct a set of overhead cable dancing models, the number of the overhead cable position information source partitions used is no less than three groups, that is, no less than three groups of polyline models are constructed based on no less than three groups of partitions;

[0021] Connecting each set of overhead cable position information representing the positioning units on the polyline model adjacent to each other to construct a set of closed three-dimensional models, which are recorded as overhead cable dancing models;

[0022] The overhead cable dancing model constructed by running the construction module is stored in the construction module.

[0023] Furthermore, the overhead cable dancing model constructed by the construction module and the overhead cable dancing model safety space created by the creation module are both constructed and created in the same three-dimensional space;

[0024] The creation module is internally provided with submodules, including:

[0025] An editing unit, used by a system end user to edit position coordinates in a three-dimensional space for constructing a galloping model of an overhead cable;

[0026] Among them, there are no less than eight groups of position coordinates edited by the system-side user in the editing unit, and the eight groups of position coordinates are adjacent to each other in three-dimensional space to obtain a group of limited and closed spatial areas, namely the overhead cable dancing model safety space.

[0027] Furthermore, during the operation phase of the rendering module, the overhead cable dancing model and the overhead cable dancing model safety space are rendered in two different colors.

[0028] Furthermore, the logic for evaluating whether the overhead cable is safe in the evaluation module is:

[0029] Whether the rendered dancing overhead cable model is exposed within the rendered dancing overhead cable model safe space;

[0030] If yes, it means that the overhead cable is in an unsafe state; if no, it means that the overhead cable is in a safe state.

[0031] Furthermore, the evaluation logic of the dynamic trend of overhead cable risk in the evaluation module is expressed as follows:

[0032]

[0033] Where: N is the dynamic trend performance value of overhead cable risk; n is the set of corner points on the overhead cable dancing model; d(p i ,p(near) space ) is the distance from the i-th corner point on the overhead cable galloping model to the nearest point on the boundary of the overhead cable galloping model safety space; ω i To find d(p i ,p(near) space ) when the configuration weight is set; N1, N2, and N3 are the dynamic trend performance values ​​of overhead cable risk for the latest three groups of requests;

[0034] Among them, if equation (2) in the above formula is established, it means that there is a risk of overhead cable dancing. Conversely, if the situation is not in equation (2), it means that the risk of overhead cable dancing is yet to be determined.

[0035] Furthermore, the configuration weight is greater than zero and less than or equal to one, and obeys: the farther the source position sensor corresponding to the i-th group of corner points on the overhead cable dancing model is from the midpoint of the overhead cable, the smaller the value, and vice versa.

[0036] Furthermore, the monitoring module is interactively connected to a positioning unit and a storage unit at a lower level through a wireless network, the monitoring module is interactively connected to a construction module through a wireless network, the construction module is interactively connected to the storage unit through a wireless network, the construction module is interactively connected to a creation module through a wireless network, the creation module is interactively connected to an editing unit through a wireless network, the creation module is interactively connected to a rendering module and an evaluation module through a wireless network, and the rendering module and the evaluation module are interactively connected to the output module through a wireless network.

[0037] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0038] The present invention provides an intelligent assessment system for the galloping risk of overhead cables. During operation, the system senses the galloping information of the overhead cables through positioning sensors, thereby constructing a visual galloping model of the overhead cables based on the galloping information of the overhead cables, further setting a safe space for the overhead cable galloping model, and comparing the safe space of the overhead cable galloping model with the overhead cable galloping model to determine whether the galloping problem of the overhead cable is within a safe and controllable range. At the same time, based on the changes in the galloping model, the system synchronously assesses the galloping risk situation of the overhead cables, thereby bringing comprehensive safety management to the overhead cables.

[0043] The present invention will be further described below with reference to the embodiments.

[0044] Example 1:

[0045] This embodiment is based on an intelligent assessment system for the risk of galloping of overhead cables. Figure 1 Shown, including:

[0046] Monitoring module, used to monitor the dancing information of overhead cables in real time;

[0047] The monitoring module is equipped with submodules, including:

[0048] Positioning unit, used to locate the position information of overhead cables in real time;

The positioning unit continuously operates based on the operation cycle to locate the position information of the overhead cable. The storage unit operates synchronously with the positioning unit and distinguishes and stores the overhead cable position information based on the positioning timestamp of the overhead cable position information.

[0051] A construction module is configured to receive the overhead cable galloping information monitored by the monitoring module and construct an overhead cable galloping model based on the overhead cable galloping information;

[0052] The overhead cable dancing model constructed by the construction module and the overhead cable dancing model safety space created by the creation module are both constructed and created in the same three-dimensional space;

[0053] The creation module has submodules set up inside, including:

[0054] An editing unit, used by a system end user to edit position coordinates in a three-dimensional space for constructing a galloping model of an overhead cable;

[0055] The editing unit includes at least eight sets of position coordinates edited by the system end user, and the eight sets of position coordinates are adjacently connected to each other in three-dimensional space to obtain a set of limited and closed spatial areas, namely, the safe space of the overhead cable dancing model;

[0056] Creation module for creating a safe space for the overhead cable dancing model;

[0057] a rendering module, configured to obtain the overhead cable dancing model constructed in the construction module and the overhead cable dancing model safety space created in the creation module, and render the overhead cable dancing model and the overhead cable dancing model safety space;

[0058] an evaluation module configured to receive the overhead cable dancing model and the overhead cable dancing model safety space rendered by the rendering module, and evaluate the safety of the overhead cable and its risk dynamic trend based on the rendered overhead cable dancing model and the overhead cable dancing model safety space;

[0059] The evaluation logic of the dynamic trend of overhead cable risk in the evaluation module is expressed as follows:

[0060]

[0061] Where: N is the dynamic trend performance value of overhead cable risk; n is the set of corner points on the overhead cable dancing model; d(p i ,p(near) space ) is the distance from the i-th corner point on the overhead cable galloping model to the nearest point on the boundary of the overhead cable galloping model safety space; ω i To find d(p i ,p(near) space ) when the configuration weight is set; N1, N2, and N3 are the dynamic trend performance values ​​of overhead cable risk for the latest three groups of requests;

[0062] Among them, based on the above formula, if formula (2) is established, it means that there is a risk of overhead cable galloping. On the contrary, if it is not the case of formula (2), it means that the risk of overhead cable galloping is yet to be determined;

[0063] The configuration weight is greater than zero and less than or equal to one, and obeys: the farther the source position sensor corresponding to the i-th group of corner points on the overhead cable dancing model is from the midpoint of the overhead cable, the smaller the value, and vice versa;

[0064] The output module is used to obtain the evaluation results of whether the overhead cables are safe and the risk dynamic trend in the evaluation module, and output the evaluation results;

[0065] The monitoring module is interactively connected to the positioning unit and the storage unit through a wireless network. The monitoring module is interactively connected to the construction module through a wireless network. The construction module is interactively connected to the storage unit through a wireless network. The construction module is interactively connected to the creation module through a wireless network. The creation module is interactively connected to the editing unit through a wireless network. The creation module is interactively connected to the rendering module and the evaluation module through a wireless network. The rendering module and the evaluation module are interactively connected to the output module through a wireless network.

[0066] In this embodiment, the monitoring module operates to monitor the dancing information of the overhead cable in real time, the positioning unit locates the position information of the overhead cable in real time, the storage unit synchronously receives the position information of the overhead cable located by the positioning unit, and stores the position information of the overhead cable. The construction module further receives the dancing information of the overhead cable monitored by the monitoring module, and constructs an overhead cable dancing model based on the dancing information of the overhead cable. The editing unit synchronizes the system end user to edit the position coordinates in the three-dimensional space of the overhead cable dancing model. The creation module is post-operated to create a safe space for the overhead cable dancing model, and then the rendering module obtains the safe space. The overhead cable dancing model constructed in the construction module and the overhead cable dancing model safety space created in the creation module are taken, and the overhead cable dancing model and the overhead cable dancing model safety space are rendered. The evaluation module further receives the overhead cable dancing model and the overhead cable dancing model safety space rendered in the rendering module, and evaluates whether the overhead cable is safe and the risk dynamic trend based on the rendered overhead cable dancing model and the overhead cable dancing model safety space. Finally, the evaluation results of whether the overhead cable is safe and the risk dynamic trend in the evaluation module are obtained through the output module, and the evaluation results are output.

[0067] Through the operation of the system in the above embodiment, a visual dancing safety monitoring and prediction service is provided for the overhead cable, ensuring that the overhead cable performs daily power transmission and distribution tasks more safely and stably.

[0068] See also Figure 2 As shown in the figure, based on the marks in the figure, in Figure (a), based on the arrow instructions, the construction process of the overhead cable dancing model is shown, and based on Figure (b), the safety space of the overhead cable dancing model is shown.

[0069] Example 2:

[0070] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The following is a further detailed description of an intelligent assessment system for the risk of overhead cable galloping in Example 1:

[0071] The number of position sensors in the positioning unit follows: the higher the safety requirements of the overhead cable, the longer the overhead cable, the larger the diameter of the overhead cable, and the more frequent bad weather in the area where the overhead cable is located, the more position sensors are set. Conversely, the fewer position sensors are set;

[0072] The distance between the position sensor deployed at the midpoint of the overhead cable and the farthest group of position sensors deployed on the overhead cable follows the following rules: the higher the safety requirement of the overhead cable, the longer the length of the overhead cable, the larger the diameter of the overhead cable, the more frequent the severe weather in the area where the overhead cable is located, and the higher the accuracy requirement for dancing monitoring, the farther the distance between the two groups of position sensors will be, and vice versa, the closer the distance between the two groups of position sensors will be.

[0073] The overhead cable galloping information received by the construction module is from a storage unit of a lower submodule of the monitoring module. The construction module continuously receives and distinguishes the stored overhead cable position information in the storage unit based on a time sequence, and constructs an overhead cable galloping model based on the continuously received overhead cable position information.

[0074] The logic of the building block to construct the overhead cable galloping model is as follows:

[0075] The construction module operates based on a time sequence from early to late to receive a set of overhead cable position information in the divided intervals each time, connects the overhead cable position information in the divided intervals adjacent to each other, and obtains a set of multi-segment line models;

[0076] When setting a construction module to construct a set of overhead cable dancing models, the number of the overhead cable position information source partitions used is no less than three groups, that is, no less than three groups of polyline models are constructed based on no less than three groups of partitions;

[0077] Connecting each set of overhead cable position information representing the positioning units on the polyline model adjacent to each other to construct a set of closed three-dimensional models, which are recorded as overhead cable dancing models;

[0078] The overhead cable dancing model constructed by running the construction module is stored in the construction module.

[0079] In this embodiment, through the above settings, further operation data support is provided for the system in Example 1, ensuring that the system in Example 1 can operate stably, complete the visual dancing monitoring of the overhead cable, and ensure the safe and stable daily operation of the overhead cable.

[0080] Example 3:

[0081] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The following is a further detailed description of an intelligent assessment system for the risk of overhead cable galloping in Example 1:

[0082] During the running phase of the rendering module, the overhead cable dancing model and the overhead cable dancing model safety space are rendered in two different colors.

[0083] The logic for evaluating whether overhead cables are safe in the assessment module is:

[0084] Whether the rendered dancing overhead cable model is exposed within the rendered dancing overhead cable model safe space;

[0085] If yes, it means that the overhead cable is in an unsafe state; if no, it means that the overhead cable is in a safe state.

[0086] Through the above settings, further operation logic limitations are provided for the rendering module and evaluation module of the system in Example 1.

[0087] In summary, in the above embodiment, during operation, the system perceives the dancing information of the overhead cable through positioning sensors, and thus constructs a visual dancing model of the overhead cable based on the dancing information of the overhead cable, further sets a safe space for the overhead cable dancing model, and compares the safe space of the overhead cable dancing model with the overhead cable dancing model to determine whether the dancing problem of the overhead cable is within a safe and controllable range. At the same time, based on the changes in the dancing model, the overhead cable dancing risk situation is synchronously evaluated, bringing comprehensive safety management to the overhead cables.

[0088] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
