Description
TECHNICAL FIELD
[0001] The present application relates to the field of urban carbon emission monitoring and management, and particularly relates to a carbon emission monitoring and management method and system for a substation. BACKGROUND
[0002] As an important hub of power transmission and distribution, the energy efficiency and emission level of substations directly affect the overall carbon emission performance of the urban power supply area. Therefore, for real-time monitoring and management of substation carbon emissions, not only accurate data collection and analysis are needed, but also deep integration with the overall operation status of the urban power supply area is needed to ensure the accuracy of monitoring and the comprehensiveness of management. However, existing substation carbon emission monitoring methods are usually limited to carbon emission estimation of a single device or a local area, and do not take into account the dynamic changes of the entire urban power supply network.
[0003] The existing carbon emission monitoring technology mainly relies on data collection of local equipment and carbon emission calculation based on emission factors, which has obvious limitations. First, the monitoring method mostly relies on the operation data of a single device, such as the energy consumption of a transformer or a switching device, but the carbon emissions of these devices only account for a part of the emissions of the entire substation or urban power supply system. Second, the power load, energy structure, external climate, and other factors of the urban power supply area are also changing, and if these factors are not fully collected and considered, the accuracy of the monitoring results will be greatly reduced. For example, during peak electricity consumption, the load of the substation may fluctuate sharply, causing significant changes in its carbon emission level, and this dynamic change is not effectively monitored, affecting the true reflection of the emission data.
[0004] In addition, the existing monitoring system has serious deficiencies in data collection and cannot comprehensively obtain the operation status of the substation and its surrounding area. For example, some systems only focus on energy consumption data, ignoring environmental factors, device operation efficiency, system scheduling strategies, and other key factors. The incompleteness of these data leads to inaccuracy in carbon emission monitoring and cannot effectively reflect the carbon emission level of the substation under different loads and different operating conditions. Therefore, the existing technology needs to be improved, and a more comprehensive monitoring method should be adopted to integrate more operating data and environmental factors to provide more accurate basis for carbon emission management of substations.

[0045] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and the present application will be further described in detail below with specific embodiments in conjunction with the drawings.
[0046] As shown in Figure 1 , a carbon emission monitoring and management method for substations includes the following steps:
[0047] A1, collect carbon emission related information of substations in urban power supply areas, the carbon emission related information of the substations includes different urban power supply area different electricity group different regional power consumption data and different regional population change before the occurrence of the urban power supply area different electricity group electrical equipment operation efficiency information within a preset time;
[0048] In order to realize the state monitoring management of large-scale different climate, environment and city power supply area, first of all, the carbon emission related information of the substation of the city power supply area needs to be collected. These data can provide information about the performance of the city power supply area in the running process, different regional power consumption data and related electrical equipment operation efficiency information, which provides the basis for subsequent state evaluation and different regional population change adjustment;
[0049] The electrical equipment operation efficiency information of different power groups in the city power supply area includes:
[0050] Load rate and power factor: collect the load rate and power factor of the city power supply area, and analyze the fluctuation of the load rate and power factor; The fluctuation of load rate and power factor can reflect the stability of the city power supply area. The load rate and power factor parameters of the city power supply area need to be collected in unit time, and the fluctuation is recorded.
[0051] Device loss: based on the temperature monitoring device to monitor and collect the device loss of the city power supply area, including the maximum, average and variance of the device loss, etc. The change of device loss can reflect the mechanical operation state of the city power supply area and the change of the population of different regions.
[0052] Running time: use the power equipment monitoring platform to monitor and collect the running time change of the city power supply area, including the running time inside and outside the device. The abnormal change of running time can indicate that the city power supply area has overload, poor heat dissipation and other changes of the population of different regions.
[0053] Device health status: based on the remote sensing system to monitor and collect the device health status signal generated by the city power supply area, and analyze it. The device health status signal can provide the state information inside the city power supply area.
[0054] Load change: based on the household management system to collect the load change around the city power supply area, and count the influence change caused by different load changes, and count the abnormal change of the influence caused by different load changes.
[0055] Power quality: monitor and collect the power quality of the city power supply area, analyze the peak value and fluctuation interval of the device loss change, and the test result of the power quality can provide information about the insulation performance.
[0056] By collecting and recording the electrical equipment operation efficiency information of these different power consumption groups, an information library of the urban power supply area is established for subsequent data analysis, correlation analysis and model ReLU function calculation. The load rate and power factor are collected in unit time, and the equipment loss, operation time, equipment health status, load change and power quality are collected according to the preset urban area distribution. By collecting the carbon emission related information of the transformer substation in the urban power supply area, the basic data of the performance and different regional power consumption data of the urban power supply area in the operation process can be provided, which provides an important basis for subsequent state evaluation, different regional household population change adjustment and performance optimization.
[0057] By analyzing the carbon emission related information of the transformer substation, the stability, mechanical operation state, insulation performance and potential different regional household population change of the urban power supply area can be revealed. In addition to the fluctuation data of the load rate and power factor, the urban power supply area is comprehensively monitored and managed through various detection means such as air temperature monitoring device, power equipment monitoring platform, equipment health status detection, household management system and power quality detection. The state information of the urban power supply area is collected from different angles to improve the accuracy of different regional household population change detection and adjustment.
[0058] By collecting the carbon emission related information of the transformer substation in the urban power supply area and the electrical equipment operation efficiency information, the performance, different regional power consumption data and electrical equipment operation efficiency information of the urban power supply area can be comprehensively understood, and the basic data and basis for subsequent state evaluation, different regional household population change adjustment and performance optimization are provided.
[0059] A2、According to the electrical equipment operation efficiency information statistics, the electrical equipment operation efficiency information of different power consumption groups in the urban power supply area is classified to obtain the statistical area different climate, environmental electrical equipment operation efficiency information species, emission source type and greenhouse gas concentration. The statistical area different climate, environmental electrical equipment operation efficiency information species include load rate and power factor, and the emission source type and greenhouse gas concentration include equipment loss, operation time, equipment health status, load change and power quality.
[0060] In this step, according to the electrical equipment operation efficiency information statistics, the electrical equipment operation efficiency information of different power consumption groups in the urban power supply area is classified, and the electrical equipment operation efficiency information of different power consumption groups is divided into two different information, i.e. statistical area different climate, environmental electrical equipment operation efficiency information species, emission source type and greenhouse gas concentration.
[0061] The load rate and power factor are included in the information of the electrical equipment operation efficiency in different climates and environments in the statistical area. The data can be collected by monitoring and collecting the load rate and power factor parameters of the city power supply area per unit time;
[0062] The emission source type and greenhouse gas concentration include equipment wear and tear, operation time, equipment health, load change, and power quality, which are used to monitor and collect the state of equipment wear and tear, operation time, equipment health, load change, and power quality during operation in the city power supply area;
[0063] The classification basis of the information of the electrical equipment operation efficiency in different climates and environments in the statistical area, the emission source type, and the greenhouse gas concentration is:
[0064] Different types of different regional population changes correspond to different electrical equipment operation efficiency information. By classifying the load rate and power factor separately from other multiple characteristic data, different types of different regional population changes can be more targeted for judgment and analysis. Load rate and power factor fluctuations are more easily related to different climates and different regional population changes, while equipment wear and tear, operation time, sound, and other data are more easily related to mechanical or insulating different regional population changes. Load rate and power factor are more convenient to collect in unit time monitoring and management. Through these data, preliminary different regional population changes can be quickly judged;
[0065] The emission source type and greenhouse gas concentration involve more sensor collection and detection equipment, which requires a certain amount of time and cost for collection. Therefore, by pre-setting a pre-set emission factor type, if the management emission factor of the information of the electrical equipment operation efficiency in different climates and environments in the statistical area is less than the pre-set emission factor type, the emission source type and greenhouse gas concentration can be avoided from being frequently set, thereby improving the management effect.
[0066] By dividing the electrical equipment operation efficiency information into two information, different types of different regional population changes can be more targeted for judgment and analysis. By pre-setting a pre-set emission factor type, if the management emission factor of the information of the electrical equipment operation efficiency in different climates and environments in the statistical area is less than the pre-set emission factor type, the emission source type and greenhouse gas concentration can be avoided from being frequently set, thereby improving the management effect. By classifying different types of electrical equipment operation efficiency information, more accurate judgment and adjustment results can be obtained by comprehensively analyzing the relevance between different characteristic data.
[0067] A3, upload the information of different climate, environmental electrical equipment operation efficiency, information types, emission source types, greenhouse gas concentrations and corresponding different regional power consumption data of different power consumption groups in the city power supply area to the graph convolutional neural network model, establish meteorological condition electrical equipment operation efficiency fluctuation management algorithm and different regional, emission source distribution electrical equipment operation efficiency fluctuation management algorithm;
[0068] The establishment steps of the meteorological condition electrical equipment operation efficiency fluctuation management algorithm are:
[0069] According to the carbon emission related information of the city power supply area substation collected in step A1, the information types of different power consumption groups of electrical equipment operation efficiency in the city power supply area and the corresponding different regional power consumption data are sorted out;
[0070] The information types of different climate, environmental electrical equipment operation efficiency in the statistical area are processed and spatio-temporal convolution is performed to convert the original data into practical features for use by the graph convolutional neural network model;
[0071] According to the problem description, select a graph convolutional neural network model suitable for this scenario, use the selected algorithm to calculate the model ReLU function, and adjust the parameters of the model;
[0072] After the ReLU function calculation is completed, the relevant parameters of the model are extracted as the output of the meteorological condition electrical equipment operation efficiency fluctuation management algorithm.
[0073] The establishment steps of the different regional, emission source distribution electrical equipment operation efficiency fluctuation management algorithm are:
[0074] According to the carbon emission related information of the city power supply area substation collected in step A1, the information types of different power consumption groups of electrical equipment operation efficiency in the city power supply area and the corresponding different regional power consumption data are sorted out;
[0075] Use the convolutional neural network model for training, use the emission source type and greenhouse gas concentration as the independent variable, and use the different regional power consumption data as the node to perform data graph structure modeling, and perform ReLU function calculation on the model;
[0076] After the ReLU function calculation is completed, the different regional, emission source distribution electrical equipment operation efficiency fluctuation management algorithm is used to predict the different regional power consumption data of the city power supply area,
[0077] The different regional, emission source distribution electrical equipment operation efficiency fluctuation management algorithm uses the convolutional neural network model for training,
[0078] Convolutional neural network model architecture
[0079] A convolutional neural network (CNN) is used to extract key features of electrical equipment operational efficiency. Here is a typical architecture of a CNN model:
[0080] Input Layer: The input data is usually multi-dimensional features of equipment operation, such as voltage, current, temperature, etc., which can be represented as a matrix (e.g., each row represents a timestamp and each column represents a device feature).
[0081] Convolutional Layer: The convolutional layer is used to extract local features from the input data. For example, a set of filters (convolution kernels) is applied to the device's operational data to extract feature maps.
[0082] Activation Layer: The ReLU (Rectified Linear Unit) activation function is commonly used to introduce non-linear transformations, improving the model's fitting ability.
[0083] Pooling Layer: Pooling operations are used for downsampling, reducing the size and computational load of feature maps while preserving key information.
[0084] Fully Connected Layer: The extracted features are classified or regressed through the fully connected layer, outputting the predicted value of the device's operational efficiency.
[0085] Data Formatting and Input: Assuming the input data is x, its shape is m x n, where m is the number of data samples and n is the dimension of the features. For a convolutional neural network, the data is organized into a three-dimensional matrix, with each input sample having dimensions h x w x c (where h and w are the height and width of the feature map, and c is the number of input channels). If it is time series data, it can be converted into a time window or sliding window form.
[0086] Forward Propagation of the Model: The convolutional neural network extracts data features through a series of convolution operations and activation functions. Assuming the input data is X and the convolution kernel used by the convolutional layer is W, the output of the convolution operation is: Z = X * W + b
[0087] where * represents the convolution operation, b is the bias term, and Z is the output of the convolutional layer. Non-linear transformation is performed through the activation function f (such as ReLU): A = f(Z)
[0088] Pooling layers are usually used to reduce computational complexity and reduce overfitting, and their operations can be max pooling (MaxPooling) or average pooling (Average Pooling). For max pooling operations, assuming the input feature map A is h x w in size, the output of the pooling operation is:
[0089] P = MaxPool(A)
[0090] This operation selects the maximum value in each window, reducing the size of the feature map.
[0091] After convolution and pooling operations, the network passes these feature vectors to fully connected layers for prediction. The fully connected layers map high-dimensional features to the target output space, such as the operational efficiency prediction of electrical equipment. Assuming F is the input feature of the fully connected layer, W f is the weight matrix, and b f is the bias term, then:
[0092] Y = FW f + b f
[0093] where Y is the predicted value of the output layer, representing the operational efficiency of electrical equipment.
[0094] A loss function is used to measure the gap between the predicted value and the actual value. For regression problems, the commonly used loss function is Mean Squared Error (MSE):
[0095]
[0096] where y i is the actual value, is the model predicted value, and N is the number of samples. An optimization algorithm (such as gradient descent or Adam optimizer) is used to minimize the loss function, adjusting the network's weights W and biases b, and the update process is as follows:
[0097]
[0098] where η is the learning rate, and are the gradients of the loss function with respect to the weights and biases.
[0099] The summary of the training process includes:
[0100] Data preparation: Collect and preprocess the operational data of electrical equipment.
[0101] Model design: Build a CNN model, including convolution layers, pooling layers, and fully connected layers.
[0102] Forward propagation: Input data into the model, extract features through convolution operations and pooling operations, and finally predict the device operational efficiency through fully connected layers.
[0103] Loss function calculation and optimization: Calculate the prediction error through the loss function, and adjust the model parameters using the optimization algorithm.
[0104] Training and evaluation: Use the training data for multiple iterations of training, and use the validation set to evaluate the performance of the model.
[0105] The trained model can monitor the operation efficiency of the equipment in real time, predict the efficiency fluctuation of the equipment according to the input real-time data, and provide support for the operation and maintenance decision of the substation or other electrical facilities, such as adjusting the load and optimizing the equipment operation strategy.
[0106] Through the convolutional neural network (CNN) for training and management of electrical equipment operation efficiency fluctuation, effective features can be automatically extracted from multi-dimensional input data, and the efficiency change of the equipment can be accurately predicted. Through the loss function optimization in the training process, CNN can gradually improve the accuracy of prediction, and provide effective support for the management of electrical equipment.
[0107] The different regional power consumption data is corresponded with the actual different regional power consumption data; specifically, the corresponding relationship between the different regional power consumption data and the actual different regional power consumption data is obtained by performing ReLU function calculation and model training on the carbon emission related information of the substation, and the statistical deviation between the different regional power consumption data and the actual different regional power consumption data is calculated by performing classification and regression on the carbon emission related information of the substation and the graph convolutional neural network model.
[0108] The input of the meteorological condition electrical equipment operation efficiency fluctuation management algorithm is the statistical regional different climate, environment electrical equipment operation efficiency information type, and the output is the management emission factor of the different regional, emission source distribution electrical equipment operation efficiency fluctuation management algorithm; the input of the different regional, emission source distribution electrical equipment operation efficiency fluctuation management algorithm is the emission source type, greenhouse gas concentration and the determined management emission factor, and the output is the different regional power consumption data of the urban power supply area.
[0109] This step can obtain complete input information by sorting and processing the different power consumption groups electrical equipment operation efficiency information type and different regional power consumption data of the urban power supply area, so that the electrical equipment operation efficiency fluctuation management algorithm can more accurately judge the state of the equipment and the different regional power consumption data; the selected graph convolutional neural network model is calculated by using the prepared ReLU function calculation data, and the model parameters are adjusted, which can improve the accuracy and performance of the model by continuously optimizing the model parameters and algorithm selection; by outputting the management emission factor, the importance of each feature to the judgment of the different regional power consumption data can be understood, so as to better understand the relationship between the electrical equipment operation efficiency fluctuation and the different regional power consumption data.
[0110] In summary, the electrical equipment operation efficiency fluctuation management algorithm can more accurately evaluate the state of the urban power supply area and the different regional power consumption data, and provide effective decision support and different regional household population change exclusion guidance for the braking personnel.

[0117] A5, compare the management emission factor of the different area, emission source distribution electrical equipment operation efficiency fluctuation management algorithm with the preset emission factor category: when the management emission factor category is less than the preset emission factor category, there is no need to set the emission source type and greenhouse gas concentration, and the collection and analysis of the different climate, environmental electrical equipment operation efficiency information categories in the statistical area continue;
[0118] A6、In the case of the management emission factor category being equal to or greater than the preset emission factor category, the emission source type and the greenhouse gas concentration are set, and the emission source type and the greenhouse gas concentration are input into the different area, emission source distribution electrical equipment operation efficiency fluctuation management algorithm together with the management emission factor to obtain the different area power consumption data of the urban power supply area.
