Technical Field

[0001] The present application relates to the technical fields of artificial intelligence and sound source localization, and in particular to a method and device for monitoring electromagnetic radiation in a substation and applications thereof. Background Art

[0002] As an important part of the power system, the transformer of the substation uses the principle of electromagnetic induction to achieve power conversion. When the conductor moves in the magnetic field or the magnetic field changes, an induced electromotive force will be generated in the conductor, thereby achieving power conversion. During the operation of the transformer, due to the change of the electromagnetic field, electromagnetic radiation will be generated to the surrounding environment, causing electromagnetic pollution. If the human body is exposed to radiation doses exceeding the safe level for a long time, it is easy to cause certain effects on the body. Therefore, how to monitor the electromagnetics of the substation is the current research focus.

[0072] In one embodiment, Figure 1 As shown, a method for monitoring electromagnetic radiation of a substation is provided, which is described by taking the method applied to a terminal as an example, and includes the following steps:

[0073] Step S101, obtaining equipment information of each electrical device of the substation, connection information between each electrical device, and boundary restriction information of the substation, and generating an electromagnetic field model of the substation based on the equipment information and connection information through an electromagnetic field modeling strategy.

[0074] In this embodiment, the terminal obtains the equipment information of each electrical device of the substation and the connection information between each electrical device in response to the user's information upload operation, wherein the electrical equipment includes but is not limited to transformers, switchgear, mutual inductors, lightning arresters, control systems, cables and busbars, buildings and facilities, etc. The equipment information of each electrical device includes the structural information of the electrical device and the electromagnetic radiation characteristics of the electrical device, wherein the structural information is the three-dimensional structure of the electrical device, and the electromagnetic radiation propagation characteristics of the electrical device are information such as electromagnetic gain, radiation direction, impedance coefficient, and reflection coefficient. The connection information between each electrical device includes the structural connection information between the electrical devices and the current transmission connection information between the electrical devices. Then, the terminal obtains the boundary restriction information of the substation. Among them, the boundary restriction information includes the electromagnetic radiation influence information of the external environment and the boundary electromagnetic radiation restriction information of each electrical structure. Among them, the electromagnetic radiation influence information of the environment will affect the radiation decay of the electromagnetic in the external air, thereby increasing / decreasing the electromagnetic radiation decay amount per unit distance (the unit distance is a manually preset distance value). The boundary electromagnetic radiation restriction information of each electrical structure is the interception amount of the boundary shell / skin of each electrical device to the electromagnetic radiation amount. Then, based on the information of each device and each connection information, the terminal generates an electromagnetic field model of the substation through an electromagnetic field modeling strategy. The electromagnetic field modeling strategy is a modeling strategy including a finite element simulation modeling strategy and a Maxwell equation electromagnetic modeling strategy. The specific modeling process will be described in detail later.

[0076] In this embodiment, the terminal adjusts the electromagnetic field model based on the boundary restriction information of the substation to obtain the target electromagnetic field model, and based on the electromagnetic field simulation strategy, simulates the current transmission process of the electromagnetic field through the target electromagnetic field model to obtain the electromagnetic distribution information of the substation. Among them, the boundary restriction information is used to adjust the electromagnetic radiation propagation coefficient of the electromagnetic field model. The specific adjustment process will be described in detail later, and the electromagnetic field simulation strategy includes but is not limited to implicit finite element method (FEA), explicit finite element method (SEA) or finite difference method (FEM) and other simulation strategies, and each simulation strategy is applicable to different substations. The specific method of screening the electromagnetic field policy strategy for substations will be described in detail later.

[0077] Step S103, based on the historical electromagnetic data of each initial electromagnetic measurement point corresponding to the electromagnetic distribution information and the electromagnetic distribution information, each initial electromagnetic measurement point is adjusted to obtain each target electromagnetic measurement point, and the current electromagnetic data of the substation is collected based on each target electromagnetic measurement point to obtain the target electromagnetic radiation information of the substation.

[0078] In this embodiment, the terminal adjusts each initial electromagnetic measurement point based on the historical electromagnetic data of each initial electromagnetic measurement point corresponding to the electromagnetic distribution information and the electromagnetic distribution information to obtain each target electromagnetic measurement point, and collects the current electromagnetic data of the substation based on each target electromagnetic measurement point to obtain the target electromagnetic radiation information of the substation. The method of adjusting the initial electromagnetic measurement point is not only to calibrate the measurement point through historical electromagnetic data, so as to screen and measure more accurate electromagnetic measurement points, but also to manually survey whether the location of the measurement point is blocked and whether other equipment is occupied, so as to identify the measurement cheapness and measurement rationality of the initial electromagnetic measurement point for screening and adjustment. The specific adjustment process will be described in detail later, where the position distribution of each target electromagnetic measurement point is as follows: Figure 2 As shown, it is the measurement point that improves the measurement accuracy and is not interfered by other obstacles such as electrical equipment, so as to ensure the measurement accuracy of the measurement point and the rationality, typicality and representativeness of the measurement point. Among them, the initial electromagnetic measurement point is the range center point of each electromagnetic radiation coverage range, and the specific identification method of the range center point of the electromagnetic radiation coverage range will be described in detail later.

[0079] Based on the above scheme, an electromagnetic field model is constructed based on the equipment information of the electrical equipment and the connection information between the electrical equipment, and the electromagnetic field model is adjusted through the boundary restriction information of the substation to obtain a target electromagnetic field model, thereby improving the simulation efficiency and accuracy of the constructed electromagnetic field model; an electromagnetic simulation strategy suitable for the substation is used to simulate the current transmission process to obtain electromagnetic distribution information, thereby identifying various measurement location points suitable for the substation; each initial electromagnetic measurement point is adjusted through historical electromagnetic data to obtain a target measurement point, so that the measurement accuracy of the target measurement point is higher and the measurement data is more reasonable, thereby avoiding the problems of poor accuracy and rationality, typicality and representativeness of manual screening of measurement points, so that each target measurement point obtained through this scheme is measured, thereby improving the accuracy of electromagnetic monitoring of the substation.

[0080] Optionally, based on the information of each device and each connection information, an electromagnetic field model of the substation is generated through an electromagnetic field modeling strategy, including: based on the equipment information of each electrical device, identifying the equipment structure information of each electrical device and the electromagnetic radiation characteristics of each electrical device, and splitting the connection information between each electrical device into structural connection information between each electrical device and current transmission connection information between each electrical device; based on the equipment structure information of each electrical device, constructing an equipment model of each electrical device, and based on the connection information between each electrical device, three-dimensionally splicing each equipment model to obtain a three-dimensional structural model of the substation; based on the electromagnetic radiation characteristics of each electrical device and the current transmission connection information between each electrical device, in the three-dimensional structural model of the substation, an electromagnetic field model of the substation is constructed through an electromagnetic field modeling strategy.

[0081] In this embodiment, the terminal identifies the device structure information of each electrical device and the electromagnetic radiation characteristics of each electrical device based on the device information of each electrical device, and splits the connection information between the electrical devices into structural connection information between the electrical devices and current transmission connection information between the electrical devices.

[0082] Then, based on the equipment structure information of each electrical equipment, the terminal constructs the equipment model of each electrical equipment through a finite element modeling program, and based on the connection information between each electrical equipment, performs three-dimensional splicing processing on each equipment model to obtain a three-dimensional structural model of the substation. Among them, the method of performing three-dimensional splicing processing on each equipment model is to first adjust the model structure parameters of each equipment model to the same proportion of structural parameters, and then perform model splicing processing on each equipment model in the same three-dimensional space.

[0083] Then, based on the electromagnetic radiation characteristics of each electrical device and the current transmission connection information between the electrical devices, the terminal constructs an electromagnetic field model of the substation in the three-dimensional structure model of the substation through the electromagnetic field modeling strategy corresponding to Maxwell's equations.

[0084] Based on the above scheme, by first constructing a three-dimensional structural model and then constructing an electromagnetic field model, the rationality and authenticity of the constructed electromagnetic field model are improved.

[0085] Optionally, based on the boundary restriction information of the substation, the electromagnetic field model is adjusted to obtain a target electromagnetic field model, including: based on the boundary restriction information of the substation, identifying the electromagnetic environment factors of the substation and the electromagnetic boundary information of each electrical equipment, and based on the electromagnetic environment factors, identifying the environmental radiation decay information of the substation; based on the electromagnetic boundary information of each electrical equipment, adjusting the boundary electromagnetic radiation restriction parameters of each electrical equipment in the electromagnetic field model to obtain an initial target electromagnetic field, and based on the environmental radiation decay information, adjusting the environmental electromagnetic radiation parameters of the initial target electromagnetic field to obtain the target electromagnetic field model.

[0086] In this embodiment, the terminal identifies the electromagnetic environment factors of the substation and the electromagnetic boundary information of each electrical device based on the boundary restriction information of the substation, and identifies the environmental radiation decay information of the substation based on the electromagnetic environment factors; based on the electromagnetic boundary information of each electrical device, the boundary electromagnetic radiation restriction parameters of each electrical device of the electromagnetic field model are adjusted to obtain the initial target electromagnetic field, and based on the environmental radiation decay information, the environmental electromagnetic radiation parameters of the initial target electromagnetic field are adjusted to obtain the target electromagnetic field model. Among them, the adjustment of the boundary electromagnetic radiation restriction parameters is used to limit the amount of electromagnetic radiation radiated from the boundary of each electrical device to the environment. And each environmental electromagnetic radiation parameter is used to limit the radiation attenuation value of each electromagnetic radiation during the propagation process of a unit distance.

[0087] Based on the above scheme, the electromagnetic field model is adjusted through boundary restriction information to obtain the target electromagnetic field, thereby improving the simulation efficiency and accuracy of the constructed target electromagnetic field.

[0088] Optionally, based on the electromagnetic field simulation strategy, the current transmission process of the electromagnetic field is simulated through the target electromagnetic field model to obtain the electromagnetic distribution information of the substation, including: based on the three-dimensional structural model of the substation, identifying the electromagnetic field simulation strategy applicable to the substation, and based on the target electromagnetic field model, identifying the operation mode of the substation; obtaining the historical operation data of the substation, and for each preset time period, based on the operation mode of the substation, in the target electromagnetic field model, simulating the historical operation process of the substation in each preset time period through the electromagnetic field simulation strategy to obtain the simulation operation log of each preset time period; for each preset time period, based on the simulation operation log of the preset time period, identifying and collecting the simulation operation information at the end time of each preset time period, and the electromagnetic radiation information of the preset time period, and Based on the sub-historical operation data of the preset time period in the historical operation data and the simulation operation information, the target electromagnetic field model is adjusted to obtain a new target electromagnetic field model; the new target electromagnetic field model replaces the target electromagnetic field model, the next preset time period replaces the preset time period, and the simulation operation log based on the preset time period is returned to execute, the simulation operation information of the preset time period and the electromagnetic radiation information of the preset time period are identified; based on the operation mode of the substation, in the target electromagnetic field model, the historical operation process steps of the substation in each preset time period are simulated through the electromagnetic field simulation strategy; until all preset time periods have completed the iteration process, the electromagnetic radiation information of each preset time period is obtained; based on the electromagnetic radiation information of each preset time period and the simulation order of each preset time period, the electromagnetic distribution information of the substation is generated.

[0089] In this embodiment, the terminal identifies the electromagnetic field simulation strategy applicable to the substation based on the three-dimensional structure model of the substation, and identifies the operation mode of the substation based on the target electromagnetic field model. The operation mode of the substation is the operation process such as the current transmission direction and current transmission path of the substation.

[0090] Among them, the method for identifying the electromagnetic field simulation strategy applicable to the substation is that the terminal identifies the number of boundaries in the three-dimensional structural model of the substation and the geometric shape of the three-dimensional structural model of the substation. Then, the terminal queries the boundary number range and geometric shape range corresponding to different electromagnetic field simulation strategies in the strategy database, thereby identifying the electromagnetic field simulation strategy applicable to the substation.

[0091] Then the terminal obtains the historical operation data of the substation, and based on the operation mode of the substation, in the target electromagnetic field model, through the electromagnetic field simulation strategy, the historical operation process of the substation in each preset time period, and obtains the simulation operation log of each preset time period.

[0092] Afterwards, for each preset time period, the terminal identifies the simulation operation information of the preset time period and the electromagnetic radiation information of the preset time period based on the simulation operation log of the preset time period, and based on the sub-historical operation data of the preset time period in the historical operation data, and the simulation operation information, when the deviation value between the current output data corresponding to the simulation operation information and the current output data corresponding to the sub-historical operation data is greater than the deviation threshold preset in the terminal, the terminal adjusts the simulation parameters of the target electromagnetic field model to obtain a new target electromagnetic field model.

[0093] The terminal replaces the target electromagnetic field model with the new target electromagnetic field model, replaces the preset time period with the next preset time period, and returns to execute the substation-based operation mode. In the target electromagnetic field model, the electromagnetic field simulation strategy is used to simulate the historical operation process steps of the substation in the preset time period to obtain the electromagnetic radiation information of each preset time period.

[0094] Finally, the terminal generates electromagnetic distribution information of the substation based on the electromagnetic radiation information of each preset period and the simulation order of each preset period, wherein the electromagnetic distribution information includes electromagnetic radiation quantity information of each location point of the substation obtained by overlapping multiple electromagnetic radiation propagation attenuation ranges.

[0095] Based on the above scheme, after screening the electromagnetic simulation strategy suitable for the substation, the simulation is carried out. During the simulation process, the simulation parameters are adjusted by identifying whether the simulation output results meet expectations to ensure the accuracy and practicality of the simulation.

[0096] Optionally, based on the historical operation data and the simulation operation information, the target electromagnetic field model is adjusted to obtain a new target electromagnetic field model, including: in the historical operation data, sub-historical operation data of a preset time period is screened, and each data deviation value between the simulation operation data and the sub-historical operation data in the simulation operation information of the preset time period is calculated; when there is an abnormal data deviation value greater than a deviation threshold, based on the simulation operation data corresponding to the abnormal data deviation value and the sub-historical operation data corresponding to the abnormal data deviation value, the simulation parameters corresponding to the simulation operation data in the target electromagnetic field model are adjusted to obtain a new target electromagnetic field model.

[0097] In this embodiment, the terminal selects the sub-historical operation data of the preset period in the historical operation data, and calculates the data deviation values ​​between the simulation operation data in the simulation operation information of the preset period and the sub-historical operation data. The simulation operation data includes multiple operation data, such as the current conversion amount, the current transmission amount, the current loss amount and other operation data.

[0098] When there is an abnormal data deviation value greater than a deviation threshold value preset in the terminal, the terminal adjusts the simulation parameters corresponding to the simulation operation data in the target electromagnetic field model based on the simulation operation data corresponding to the abnormal data deviation value and the sub-historical operation data corresponding to the abnormal data deviation value, so as to obtain a new target electromagnetic field model. The target electromagnetic field model includes the corresponding relationship between the data value of each sub-historical operation data and the simulation parameter, and then the terminal identifies the simulation parameter in the new target electromagnetic field model by identifying the simulation parameter adjustment value corresponding to the abnormal data deviation value.

[0099] Based on the above scheme, the simulation parameters of the target electromagnetic field model are adjusted through the data deviation value, thereby improving the accuracy and efficiency of the adjustment.

[0100] Optionally, based on the historical electromagnetic data of each initial electromagnetic measurement point corresponding to the electromagnetic distribution information and the electromagnetic distribution information, each initial electromagnetic measurement point is adjusted to obtain each target electromagnetic measurement point, including: based on the electromagnetic distribution information, each electromagnetic radiation coverage range is identified, and the center point of each electromagnetic radiation coverage range is identified as each initial electromagnetic measurement point, and the electromagnetic data of each initial electromagnetic measurement point is used as the measured electromagnetic data; based on the historical operation data of the substation, the historical electromagnetic data of each initial electromagnetic measurement point and the historical target electromagnetic data of each historical target electromagnetic measurement point in the historical operation data are identified; when the measured electromagnetic data of the initial electromagnetic measurement point is greater than or equal to the historical target electromagnetic data of the historical target electromagnetic measurement point, the initial electromagnetic measurement point is used as the initial target electromagnetic measurement point, and in response to the initial target electromagnetic measurement point Measure the adaptation information, screen the blacklist measurement points and the target electromagnetic measurement points; when the measured electromagnetic data of the initial electromagnetic measurement point is less than the historical target electromagnetic data of the historical target electromagnetic measurement point and greater than the historical electromagnetic data of the initial electromagnetic measurement point, use the initial electromagnetic measurement point as a candidate electromagnetic measurement point; when the measured electromagnetic data of the initial electromagnetic measurement point is less than the historical electromagnetic data of the initial electromagnetic measurement point, use the initial electromagnetic measurement point as a blacklist measurement point; based on the historical electromagnetic data of each blacklist measurement point and the historical electromagnetic data of each candidate electromagnetic measurement point, adjust the electromagnetic radiation parameters of the target electromagnetic field model, and return to execute the electromagnetic field simulation strategy, simulate the current transmission process of the electromagnetic field through the target electromagnetic field model, and obtain the electromagnetic distribution information step of the substation, until all initial electromagnetic measurement points are target electromagnetic measurement points.

[0101] In this embodiment, the terminal identifies each electromagnetic radiation coverage range based on the electromagnetic distribution information, and identifies the range center point of each electromagnetic radiation coverage range as each initial electromagnetic measurement point, and uses the electromagnetic data of each initial electromagnetic measurement point as the measured electromagnetic data. The range center point is a location point where the electromagnetic radiation range of multiple electrical devices is covered. The electromagnetic radiation amount measured at this location point can detect the electromagnetic radiation amount of multiple electrical devices.

[0102] The terminal identifies the historical electromagnetic data of each initial electromagnetic measurement point and the historical target electromagnetic data of each historical target electromagnetic measurement point in the historical operation data based on the historical operation data of the substation.

[0103] When the measured electromagnetic data of the initial electromagnetic measurement point is greater than or equal to the historical target electromagnetic data of the historical target electromagnetic measurement point, the initial electromagnetic measurement point is used as the initial target electromagnetic measurement point, and in response to the measurement adaptation information of the initial target electromagnetic measurement point uploaded by the staff, the blacklist measurement point and the target electromagnetic measurement point are screened. The measurement adaptation information is feedback information on whether there are electrical equipment or other obstacles affecting the laying of the measurement equipment at the initial target electromagnetic measurement point. When there are electrical equipment or other obstacles affecting the laying of the measurement equipment, the initial target electromagnetic measurement point is a blacklist measurement point, and when there are no electrical equipment or other obstacles affecting the laying of the measurement equipment, the initial target electromagnetic measurement point is a target electromagnetic measurement point. The blacklist measurement point is a position point that will not be screened as the initial electromagnetic measurement point when the target electromagnetic measurement point is screened in subsequent iterations.

[0104] When the measured electromagnetic data of the initial electromagnetic measurement point is less than the historical target electromagnetic data of the historical target electromagnetic measurement point, and is greater than the historical electromagnetic data of the initial electromagnetic measurement point, the terminal uses the initial electromagnetic measurement point as a candidate electromagnetic measurement point. The candidate electromagnetic measurement point can be re-determined whether it is suitable as a target electromagnetic measurement point during the iterative simulation process, thereby improving the accuracy of identifying whether the candidate electromagnetic measurement point is a target electromagnetic measurement point.

[0105] When the measured electromagnetic data of the initial electromagnetic measurement point is less than the historical electromagnetic data of the initial electromagnetic measurement point, the initial electromagnetic measurement point is used as a blacklist measurement point.

[0106] The terminal adjusts the electromagnetic radiation parameters of the target electromagnetic field model based on the historical electromagnetic data of each blacklist measurement point and the historical electromagnetic data of each candidate electromagnetic measurement point. The electromagnetic radiation parameters are adjusted by adjusting the electromagnetic radiation parameters to reacquire the measured electromagnetic data of each blacklist measurement point and the measured electromagnetic data of each candidate electromagnetic measurement point. When the measured electromagnetic data is different from the historical electromagnetic data, the electromagnetic radiation parameters are adjusted continuously until the measured electromagnetic data of all blacklist measurement points are the same as the corresponding historical electromagnetic data, and the measured electromagnetic data of all candidate electromagnetic measurement points are the same as the corresponding historical electromagnetic data. The terminal returns to execute the electromagnetic field simulation strategy, simulates the current transmission process of the electromagnetic field through the target electromagnetic field model, and obtains the electromagnetic distribution information of the substation, until all initial electromagnetic measurement points are target electromagnetic measurement points.

[0107] Based on the above scheme, each initial electromagnetic measurement point is adjusted through historical measurement data and measurement adaptation information of the measurement point, so as to improve the accuracy, rationality, typicality and representativeness of the obtained target electromagnetic field measurement point.
