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 based on overhead cables. Background Art

[0002] The dancing of overhead cables is extremely harmful. It will cause the cables to bend repeatedly, leading to metal fatigue and reducing their service life. It may cause accidents such as cable breakage and tower collapse, affecting the normal supply of electricity and communications. At the same time, the dynamic tension generated by the dancing may also damage equipment such as hardware and insulators, seriously threatening public safety and social stability.

[0003] The invention patent with application number 202010984547.5 discloses a method for detecting the dancing of a power transmission line cable, which comprises: using a power transmission line cable dancing detection device to calculate the maximum sag of the cable, and 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 the direction of gravity when the transmission line is dancing, and 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 power transmission line cable dancing detection device is characterized in that it comprises: an external Shell, power module, main control circuit board, dancing detection module, communication transmission module; the power 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 plate and the bottom frame cover plate; the power 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: "With the expansion of the scale of my country's power grid and the frequent occurrence of large-scale extreme weather, the probability of transmission line dancing accidents has increased significantly. In order to improve the ability of the power grid 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 conduct research on the transmission line dancing mechanism, sag detection methods and anti-dancing measures."

[0005] However, currently, most of the galloping monitoring of overhead cables is based on the 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 overhead cable dancing model safe space created in the creation module, and to render the overhead cable dancing model and the overhead cable dancing model safe space; an evaluation module is used to receive the overhead cable dancing model and the overhead cable dancing model safe space 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 overhead cable dancing model safe space; 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, used 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 the position sensors are no less than two groups. 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 positioning unit has a system-side user-defined operation cycle, and the positioning unit continuously operates based on the operation 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 subject to: 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, the fewer position sensors are set;

[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 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.

[0017] Furthermore, the overhead cable dancing information received by the construction module is derived from a storage unit of a lower submodule of the monitoring module, and 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 dancing model based on the continuously received overhead cable position information;

[0018] The logic of the building module to build the overhead cable dancing model is:

[0019] The construction module operates based on the time sequence from early to late to receive the position information of the overhead cables in a group of partitions each time, and connects the position information of the overhead cables in the partitions adjacent to each other to obtain a group of multi-segment line models;

[0020] The number of the overhead cable position information source partitions used by the construction module when constructing a set of overhead cable dancing models is set to be 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 group of overhead cable position information representing the positioning unit on the polyline model adjacent to each other to construct a group of closed three-dimensional models, which are recorded as overhead cable dancing models;

[0022] The overhead cable dancing model constructed by 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, when rendering the overhead cable dancing model and the overhead cable dancing model safety space, the rendering is distinguished by using two different colors.

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

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

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

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

[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 ith group of corner points on the overhead cable dancing model to the nearest point on the boundary of the safety space of the overhead cable dancing model; ω i To find d(p i ,p(near) space ) when the configuration weight is used; N1, N2, and N3 are the dynamic trend performance values ​​of overhead cable risks of the latest three groups of requests;

[0034] Among them, based on the above formula, if formula (2) is established, it means that there is a risk of overhead cable dancing. On the contrary, if it is not the case with formula (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, the larger the value.

[0036] Furthermore, the monitoring module is interactively connected to a positioning unit and a storage unit via a wireless network, the monitoring module is interactively connected to a construction module via a wireless network, the construction module is interactively connected to the storage unit via a wireless network, the construction module is interactively connected to a creation module via a wireless network, the creation module is interactively connected to an editing unit via a wireless network, the creation module is interactively connected to a rendering module and an evaluation module via a wireless network, and the rendering module and the evaluation module are interactively connected to the output module via 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 dancing risk of overhead cables. During operation, the system senses the dancing information of the overhead cables through positioning sensors, thereby constructing a visualized dancing model of the overhead cables based on the dancing information of the overhead cables, further setting a safe space for the dancing model of the overhead cables, and comparing the safe space of the dancing model of the overhead cables with the dancing model of the overhead cables to determine whether the dancing problem of the overhead cables is within a safe and controllable range. At the same time, based on the changes in the dancing model, the dancing risk situation of the overhead cables is synchronously assessed, thereby bringing comprehensive safety management to the overhead cables.

[0051] A construction module is used to receive the overhead cable dancing information monitored by the monitoring module, and to construct an overhead cable dancing model based on the overhead cable dancing 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] There are no less than eight sets of position coordinates edited by the system end user in the editing unit, and the eight sets of position coordinates are adjacently connected to each other in the three-dimensional space to obtain a set of limited and closed space areas, namely, the overhead cable dancing model safety space;

[0056] Creation module for creating safe spaces for overhead cable dancing models;

[0057] A rendering module is used 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 is used to receive the overhead cable dancing model and the overhead cable dancing model safety space rendered in the rendering module, and evaluate 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;

[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 ith group of corner points on the overhead cable dancing model to the nearest point on the boundary of the safety space of the overhead cable dancing model; ω i To find d(p i ,p(near) space ) when the configuration weight is used; N1, N2, and N3 are the dynamic trend performance values ​​of overhead cable risks of the latest three groups of requests;

[0062] Among them, if equation (2) is established based on the above formula, it means that there is a risk of overhead cable galloping. On the contrary, if it is not in equation (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 is subject to: 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, the larger the value;

[0064] The 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 output the evaluation results;

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 the safety of the overhead cables and the dynamic trend of risks based on the rendered overhead cable dancing model and the overhead cable dancing model safety space. Finally, the evaluation results of the safety of the overhead cables and the dynamic trend of risks 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 cables, ensuring that the overhead cables perform 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 arrows, 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] Embodiment 2:

[0070] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The intelligent assessment system for the risk of overhead cable dancing in Example 1 is further described in detail:

[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 dancing information received by the construction module is derived from the storage unit of the 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 the time sequence, and constructs the overhead cable dancing model based on the continuously received overhead cable position information.

[0074] The logic of building the overhead cable dancing model is as follows:

[0075] The construction module operates based on the time sequence from early to late to receive the position information of the overhead cables in a group of partitions each time, and connects the position information of the overhead cables in the partitions adjacent to each other to obtain a group of multi-segment line models;

[0080] Embodiment 3:

[0081] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The intelligent assessment system for the risk of overhead cable dancing in Example 1 is further described in detail:

[0082] When the overhead cable dancing model and the overhead cable dancing model safety space are rendered during the rendering module operation phase, they are rendered differently using two different colors.

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

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

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

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

[0087] In summary, in the above-mentioned embodiment, during operation, the system senses the dancing information of the overhead cable through the positioning sensor, thereby constructing a visual dancing model of the overhead cable based on the dancing information of the overhead cable, and further setting the safety space of the overhead cable dancing model. The overhead cable dancing model safety space is compared 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 the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
