Description

Technical Field

[0001] The invention relates to the technical field of high-altitude power transmission lines, and in particular to a device for limiting wind deviation and fluttering of high-altitude power transmission lines and a method for using the device. Background Art

[0002] The bare conductors of overhead transmission lines are generally not static. They will dance under the influence of various natural conditions such as wind and ice. If the dancing amplitude is too large, it will cause phase flashover, short circuit, and even tripping of the line, resulting in serious accidents such as large-scale power outages, causing significant economic losses to society.

[0003] According to a device for suppressing the dancing of an overhead power transmission line disclosed in China Publication No. "CN111478261B", the device includes a conductor, a support rod, a pulley assembly, a counterweight, a synthetic insulator, a main insulating rope and a load-bearing insulating rope. The support rod is buried obliquely on the ground, the fixed pulley is arranged above the movable pulley, the fixed pulley is connected to the support rod, the main insulating rope is wound around the conductor, two synthetic insulators are connected to the two ends of the main insulating rope, one end of the load-bearing insulating rope is connected to the upper end of the movable pulley, and the other end of the load-bearing insulating rope is connected to the lower end of one of the synthetic insulators after passing through the fixed pulley and the movable pulley in turn, and the counterweight is connected to the lower end of the movable pulley. The present invention is flexible and reliable to use, has a reasonable design, and uses a pulling method to suppress the dancing of the line to ensure the safe operation of the power transmission line. In addition, there is no need to arrange a pulling device at both ends of the line, and the line can be pulled at any position of the transmission line.

[0004] The above patent documents and prior art have the following technical problems when used:

[0005] Problem 1: Traditional wind deflection prevention technology for transmission lines can only be applied to a specific wind speed range or simple wind direction. It is difficult to effectively suppress the wind deflection of the line under complex and changeable wind conditions. Previous methods were mostly passive defense, such as increasing the strength of the tower and increasing the line spacing, but these measures cannot fundamentally solve the problem of wind deflection.

[0006] Problem 2: The existing transmission line monitoring system only monitors a few parameters and cannot fully reflect the actual status of the line. The sensor accuracy is limited, resulting in inaccurate judgment of wind yaw. Traditional control decisions often rely on manual experience or simple models, with slow data processing speed and unable to adjust control strategies in time according to changes in wind yaw.

[0007] Problem three: Traditional transmission line repair relies on manual inspections to find problems before arranging maintenance, which results in time lags. In addition, in some complex environments, such as mountains and canyons, it is difficult for maintenance personnel to quickly reach the damaged location. Manual inspections and repairs of high-altitude transmission lines pose great safety risks, especially in severe weather or high altitude areas, where the maintenance risk is high and is not conducive to actual use.

[0058] Specific embodiment 3: Figure 1-6 As shown, according to the contents in the above specific embodiments, the following contents are further disclosed:

[0059] In the above device architecture, the specific contents of each device are as follows:

[0060] The wind direction sensor of the pulse jet device adopts three-dimensional ultrasonic wind direction measurement technology, and the wind speed sensor uses the laser Doppler speed measurement principle with a measurement accuracy of ±0.1m / s. The pulse jet device is equipped with a pressure regulating valve and a pulse controller. The pressure regulating valve adjusts the jet pressure according to the command, and the pulse controller is used to accurately control the frequency and duration of the jet. The jet device is set up in a group every 5-10 meters along the transmission line. The specific value can be adjusted according to factors such as the line voltage level and the wind conditions in the area. For example, for high-voltage and windy areas, it can be set to a group of 5 meters, and for areas with slightly lower voltage levels and relatively mild wind conditions, it can be set to a group of 10 meters. Each group contains 3-5 jet nozzles, which are determined according to factors such as the line diameter. The number of jet nozzles can be appropriately increased for thick lines. The direction of the jet nozzle is at an angle of 30°-60° to the direction of the line. This angle is obtained through wind tunnel experiments and simulation calculations. Within this angle range, it is better to destroy the aerodynamic conditions of wind deviation and dancing.

[0061] The power module of the plasma flow generator adopts a high-frequency high-voltage power supply, which can output electrical energy with a frequency of 10kHz-50kHz and a voltage of 5kV-20kV. The electrode system adopts special electrode materials such as tungsten-copper alloy, which has a high melting point, high conductivity and good corrosion resistance. The electrode shape is a needle-plate structure, which is conducive to the generation of stable plasma under high voltage. The gas supply system can accurately control the gas flow rate at 0.1-1L / min, which is determined according to the needs of plasma generation and regulation. According to different environmental conditions, argon can be selected in areas with high humidity, and helium and other gases can be selected in areas with relatively dry air and more dust. A generator is installed every 10-20 meters around the transmission line. It is determined according to the line length and wind deviation and dancing risk assessment. The gas supply system can accurately control the gas flow rate and type, select argon, helium and other gases according to different environmental conditions, and install multiple generators around the transmission line.

[0062] The superconducting coil of the dynamic magnetic field suppression module is made of high-temperature superconducting materials, such as yttrium barium copper oxide superconducting materials, with high critical current density (greater than 10 5A / cm²) and low AC loss (less than 10⁻³W / kg). It is installed on the insulating bracket around the transmission line, keeping a distance of 0.5-1 meter from the line to avoid electromagnetic interference to the normal operation of the line while ensuring the effect of the magnetic field. It is connected to the superconducting current controller and equipped with a low-temperature cooling system, such as a liquid helium cooling system, which can maintain the temperature below the critical temperature of the superconducting material, about 77K-90K. The superconducting current controller can adjust the current to generate the corresponding magnetic field according to the dancing parameters in less than 0.1 second.

[0063] The intelligent magnetic material of the dynamic magnetic field suppression module uses new materials with magnetostrictive effect and controllable magnetism, such as Terfenol-D alloy, etc. Through nanotechnology and material composite technology, it is made into a film with a thickness of 0.1-0.5 mm or tiny particles with a diameter of 0.5-2 mm, and evenly coated on the surface of the transmission line or embedded in a specific protective casing. The protective casing uses insulating, high-strength composite materials, such as glass fiber reinforced epoxy resin). Magnetic field sensors and stress sensors are installed every 2-5 meters on the transmission line, which are determined according to the line length and the requirements for data accuracy and are connected to the magnetic material control system.

[0064] In the IoT monitoring network of the data monitoring and processing module, the sensor is connected to the local data acquisition node through ZigBee, LoRa wireless communication modules or fiber-optic wired communication.

[0085] In the above-mentioned entire device architecture, the algorithm content and steps for data processing are as follows:

[0086] Machine learning algorithms used in big data analysis and early warning model building

[0087] In the process of big data analysis and early warning model establishment, the neural network algorithm of the machine learning algorithm is used to establish a wind deviation and dancing prediction model. The forward propagation formula of the multi-layer perceptron can be expressed as:

[0088] For input layer to hidden layer:

[0089] ;

[0090] ;

[0091] in:

[0092] : is the first Input features, representing the characteristic variables in the input data, such as wind speed value, wind direction angle value, etc. These are the basic data used to analyze and predict wind swing;

[0093] is the number of input layer features;

[0094] Is the connection input layer neurons to the hidden layer The weight of each neuron indicates the strength of the connection between the input layer neurons and the hidden layer neurons. Different weight values ​​will affect the transmission and processing of information in the network. The weight is continuously adjusted through training to achieve the best prediction effect.

[0095] : Hidden layer The bias of each neuron provides an adjustable offset for each hidden layer neuron, which helps the neural network to better fit the data and make it more expressive.

[0096] :It is the hidden layer The weighted sum of the inputs of each neuron is the weighted sum of the input values ​​received by the neurons in the hidden layer. It combines the information transmitted by each feature of the input layer through the corresponding weights and the influence of the bias.

[0097] :It is the hidden layer The neurons are activated by the function The output after is the output value of the hidden layer neurons after being processed by the activation function. The activation function (such as the commonly used Sigmoid, ReLU, etc.) can introduce nonlinear factors, enabling the neural network to handle complex nonlinear relationships, thereby better modeling complex phenomena such as wind yaw and flutter.

[0098] From the hidden layer to the output layer, the output layer has only one neuron for predicting the probability of wind yaw, etc.:

[0099] ;

[0100] ;

[0101] in, is the number of neurons in the hidden layer, is the connection hidden layer neurons to the output layer The weight of a neuron, The output layer The bias of a neuron, The output layer The weighted sum of the inputs of the neurons, is the final prediction output, such as the probability of wind yaw. :The final prediction result, such as the predicted probability value of wind yaw dance, is the judgment of the entire neural network on the wind yaw dance-related situation after a series of calculations and processing based on the input data.

[0102] The implementation steps are as follows:

[0103] Sp1: Data collection and preprocessing: Collect various monitoring data including wind speed, wind direction, line vibration, etc., and store them according to time series, sensor type, line location and other dimensions. Use Spark, Flink and other technologies to clean the data and extract features, remove noise, outliers and duplicate data, and extract key features as input for the neural network.

[0104] Sp2: Network structure design: determine the number of layers of the neural network (such as the setting of input layer, hidden layer, output layer), the number of neurons in each layer, and the selection of activation function, etc.;

[0105] Sp3: Initialize weights and biases: Randomly initialize all weights in the network , and bias , ;

[0106] Sp4: Forward propagation calculation: According to the above formula, the preprocessed input data is calculated through the input layer and hidden layer in turn, and finally the prediction result of the output layer is obtained. ;

[0107] Sp5: Calculate the loss function: based on the prediction results and the actual wind yaw and actual situation (through actual observations or known label data; calculate the loss function value; such as mean square error MSE, etc.; the loss function is used to measure the gap between the predicted result and the actual situation;

[0108] Sp6: Back propagation update: Using optimization algorithms such as gradient descent, back propagation updates the weights and biases in the network according to the gradient information of the loss function to reduce the loss function value and make the prediction results more accurate;

[0109] Sp7: Repeat training: Repeat steps Sp4-Sp6 until the predetermined training stop condition is reached, such as reaching a certain number of training rounds, the loss function value is less than a certain threshold, etc.

[0110] Operation logic: The input layer receives various pre-processed monitoring data features. After these data are multiplied by the corresponding weights and added with the bias, they are weighted summed and activated in the hidden layer to obtain the output of the hidden layer. The output of the hidden layer is then used as the input of the next layer. After a similar calculation process, the prediction result of the wind yaw is finally obtained in the output layer. Then, the loss function is calculated by comparing with the actual result, and the weight and bias are adjusted in reverse according to the gradient information of the loss function, so as to continuously optimize the prediction ability of the network, so that it can more accurately predict the probability, amplitude and time of wind yaw.

[0111] Able to handle complex nonlinear relationships: There is a complex nonlinear relationship between wind fluctuations and a variety of factors (wind speed, wind direction, line status, etc.). The neural network introduces nonlinear factors through the activation function, which can well model and predict this complex relationship. By continuously training and updating weights and biases, the neural network can automatically adapt to different data distributions and characteristics, so as to better fit the actual situation and improve the accuracy of the prediction. A fully trained neural network can make reasonable predictions for unseen data (new monitoring data) and has a certain generalization ability, which helps to give early warning of wind fluctuations and provide a scientific basis for taking prevention and control measures.

[0112] The cloud computing platform in the data collaborative processing module uses the gradient descent algorithm for model update and optimization:

[0113] When conducting more comprehensive and in-depth analysis on the cloud computing platform and using machine learning models to update and optimize the wind yaw and gallop prediction model and control strategy, optimization algorithms such as the gradient descent algorithm are used to adjust the model parameters;

[0114] For a parameter vector with parameters, such as weights and biases in a neural network, the loss function is , the formula for updating parameters is:

[0115] ;

[0116] in, , : represent the updated and current parameter vectors respectively. In a neural network, the parameter vector contains all adjustable parameters such as weights and biases. The performance of the model is optimized by continuously updating these parameters.

[0117] : Learning rate, which determines the step size of each parameter update. If the learning rate is too large, it may cause the parameters to update too quickly, miss the optimal solution, or even increase the loss function value; if the learning rate is too small, the parameter update will be very slow and the training time will be very long. Therefore, it is necessary to choose a reasonable learning rate;

[0118] : The gradient of the loss function at the current parameter vector. The gradient indicates the direction in which the loss function changes fastest at a certain point. By updating the parameters in the opposite direction of the gradient, the loss function value can be gradually reduced, thereby optimizing the model.

[0119] For the weight of a layer in a neural network (Take the update from input layer to hidden layer as an example), let the loss function be , then its gradient calculation can be expressed as:

[0120] ;

[0121] in, is the output layer outputs (such as predicted windage-related indicators), is the number of outputs of the output layer, is the hidden layer The weighted sum of the inputs of the neurons, as in the previous formula ;

[0122] : represents the partial derivative of the loss function with respect to a particular weight, which measures the effect of changing the weight on the loss function value. By calculating the partial derivatives of each weight, we can know how to adjust these weights to reduce the loss function value;

[0123] :This is a formula for the derivation of a composite function, which is used to calculate the loss function for a certain weight The partial derivative of

[0124] in, Represents the loss function for the output layer The partial derivative of the output, which reflects the impact of the change in the output result on the loss function;

[0125] Represents the output layer The output pairs of the hidden layer The partial derivative of the weighted sum of the inputs of neurons, which describes the impact of information transfer from the hidden layer to the output layer on the output result;

[0126] Represents the hidden layer The weighted sum of the inputs of neurons to a certain weight The partial derivative of Impact on the weighted sum of hidden layer inputs.

[0127] Implementation steps:

[0128] Sp1: Initialization parameters: First determine the initial parameters of the model (such as a neural network) (including all weights and biases, etc.), which can be initialized randomly;

[0129] Sp2: Calculate loss function: Calculate loss function based on current parameter values, input monitoring data, and corresponding real wind yaw and waving conditions (such as through actual observations or known label data);

[0130] Sp3: Calculate the gradient: Calculate the gradient of the loss function at the current parameter vector according to the above formula. This may involve calculating the derivative of a composite function, such as calculating the partial derivatives of each weight and bias in a neural network.

[0131] Sp4: Update parameters: Update the parameter vector according to the calculated gradient and the set learning rate according to the formula;

[0132] Sp5: Repeat Sp2-Sp4, and keep repeating the above steps until the predetermined training stop condition is reached (such as reaching a certain number of training rounds, the loss function value is less than a certain threshold, etc.).

[0133] Operation logic: First, the input monitoring data is predicted according to the current model parameters to obtain the prediction results. Then, by comparing with the actual wind yaw and flutter situation, the loss function value is calculated to measure the gap between the prediction result and the actual situation. Next, the gradient of the loss function at the current parameter vector is calculated. This gradient indicates how the parameters should be adjusted to reduce the loss function value. Finally, the parameters are updated according to the gradient and learning rate to continuously improve the prediction ability of the model, thereby more accurately optimizing the wind yaw and flutter prediction model and control strategy, and effectively optimizing the model: By continuously updating the parameters in the opposite direction of the loss function gradient, the prediction ability of the model can be gradually improved, thereby more accurately predicting the relevant situations of wind yaw and flutter, such as the probability, amplitude and time of occurrence. There is no need to manually adjust the various parameters of the model, but automatically adjust them according to the data and loss function, saving labor costs and being able to adapt to different data situations and prediction needs. By optimizing the model, it can better fit the training data, and at the same time improve the prediction ability of unseen data, that is, the generalization ability, which helps to more accurately warn and control wind yaw and flutter in practical applications.

[0146] Data flow and processing on the cloud computing platform: Receive key data uploaded by edge computing nodes, as well as more extensive meteorological data (such as more comprehensive meteorological information obtained from the meteorological department), and power grid operation data (data about the operating status of the entire power grid), and use the Kubernetes distributed computing architecture to manage and schedule resources to conduct a more comprehensive and in-depth analysis of these data, including using Spark, Flink and other technologies for data cleaning and feature extraction, removing noise, outliers and duplicate data, extracting key features such as wind speed change rate, wind direction change frequency, line vibration spectrum, and magnetic field intensity change trend as machine learning model input, updating and optimizing the wind swing prediction model and control strategy through the machine learning model, and sending collaborative control instructions to the edge computing nodes based on the evaluation results, including precise control parameters of equipment such as jet devices, superconducting coils, and magnetic material control systems, so as to achieve efficient control of the entire system, dynamically adjust the parameters of each device, and effectively suppress wind swing.

[0147] Output data, warning information output: In the big data analysis and warning model establishment link, through deep mining and analysis of massive monitoring data, a more accurate wind yaw and flutter prediction model is established using machine learning algorithms. Combined with meteorological data and transmission line operation data, the probability, amplitude and time of wind yaw and flutter are predicted in advance, and warning information is issued when it may occur. These warning information can be sent to the terminal equipment of the relevant monitoring center or operation and maintenance personnel so that prevention and control measures can be taken in time.

[0148] Control command output: After a comprehensive and in-depth analysis, the cloud computing platform sends coordinated control commands to the edge computing nodes, including precise control parameters of the jet device, superconducting coil, magnetic material control system, etc. The edge computing nodes precisely control the corresponding equipment according to these commands, realize efficient control of the entire system, and dynamically adjust the parameters of the active interference airflow system and the dynamic magnetic field suppression system to effectively suppress wind yaw.

[0149] Equipment status and line repair related output: For the line repair module, when performing repair tasks, the micro crawler robot and the flying micro robot cluster can feed back the relevant status information of the repair process (such as repair progress, whether the repair is completed, etc.) to the control center through the communication module they carry, so as to monitor the entire repair process. At the same time, when the sensor detects damage to the line or wind deflection protection device, the relevant damage information will also be fed back to the control system as output data to start the repair module for repair operations.
