[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] In one embodiment, the substation information synchronization verification method based on remote communication provided by the present application can be applied to Figure 1 In the application environment shown. Each substation 102 can communicate remotely with each other to achieve synchronization of substation information and / or verification of substation information through remote communication. Further, in one example, the substation 102 can be connected to a cloud computing platform for communication, and can call computing resources provided by the cloud computing platform to achieve synchronization and verification of substation information.

[0025] In one embodiment, the present application provides a method for synchronous verification of substation information based on remote communication, which can be applied to Figure 1 In each substation shown. Figure 2 , the method may include the following steps:

[0026] S202: Acquire actual monitoring data of the substation at each target time, where the actual monitoring data includes actual energy transmission data, actual energy reception data, and actual status data.

[0027] Among them, the present substation may be a substation that currently executes the substation information synchronization verification method based on remote communication. Exemplarily, when the power supply system includes a first substation, a second substation and a third substation, for the first substation, the present substation is the first substation itself, and the remaining substations are the second substation and the third substation. Similarly, for the second substation, the present substation is the second substation itself, and the remaining substations are the first substation and the third substation. For the third substation, the present substation is the third substation itself, and the remaining substations are the first substation and the second substation.

[0028] The target time may be the time at which information texture calculation is required. It is understood that the method for determining the target time may be set according to actual conditions, and this document does not impose any specific restrictions on this. For example, in the acquisition cycle [t1, t2], the target time t may be one or more times within the acquisition cycle, and t≥t1, t≤t2.

[0029] Actual monitoring data refers to the data actually collected in this substation. Among them, the actual energy transmission data is the actual amount of energy provided by this substation to other substations, and the actual energy reception data is the actual amount of energy provided by other substations to this substation. Actual status data refers to data that can reflect the substation status of this substation, such as any one or any combination of temperature data, power data, voltage data, current data, etc.

[0030] In this step, the substation can obtain its actual monitoring data at each target time. For example, one or more sensors, such as temperature sensors, power sensors, voltage sensors, current sensors, etc., can be set in the substation. The substation can obtain the collected data of each sensor to obtain the actual monitoring data of the substation.

[0031] S204: Determine the standard state data corresponding to each target moment according to the actual energy transmission data, the actual energy reception data and the multivariate regression equation corresponding to the substation; wherein the multivariate regression equation is constructed based on the historical monitoring data of the substation, with the energy transmission data and the energy reception data as independent variables and the state data as the dependent variable.

[0032] The historical monitoring data may be the actual monitoring data of the substation during a specific period of time. The duration, start time and end time of the specific period of time may be determined according to the actual situation, and this document does not impose any specific restrictions on this. The historical monitoring data may include the historical energy reception data, historical energy transmission data and historical status data of the substation.

[0033] In this step, data fitting can be performed based on the historical monitoring data of the substation, and a multivariate regression equation corresponding to the substation can be established. Exemplarily, the multivariate regression equation can be:

[0034]

[0035] In the formula, α1 is the first constant coefficient, β1 is the second constant coefficient, x1 is the energy receiving data, x2 is the energy transmission data, y1 is the first state data, α m is the third constant coefficient, β m is the fourth constant coefficient, y m is the mth state data, where m is a positive integer.

[0036] Since the multiple regression equation is an equation with energy transmission data and energy reception data as independent variables and state data as dependent variables, after determining the values ​​of energy transmission data and energy reception data, the corresponding state data can be determined according to the multiple regression equation. In this step, for each target moment, the actual energy transmission data corresponding to the target moment and the actual energy reception data corresponding to the target moment can be substituted into the multiple regression equation corresponding to the substation, and the standard state data corresponding to the target moment can be obtained.

[0037] It is understood that the present application may use any method to generate the multivariate regression equation corresponding to the substation, and this document does not specifically limit this. In one example, one or more sensors may be provided in the substation, and the present application may generate the multivariate regression equation according to the following steps:

[0038] Step A1: collect historical monitoring data of the substation in multiple collection cycles through various sensors, and the period length of each collection cycle is equal; the historical monitoring data of each collection cycle includes the historical energy receiving curve, the historical energy transmission curve and the historical status curve of the substation;

[0039] Step A2: for each collection period, the historical energy reception curve, the historical energy transmission curve and the historical state curve corresponding to the collection period are mapped in a two-dimensional coordinate system, and k moments are selected in the collection period; k is a positive integer;

[0040] Step A3: Perform data fitting based on the historical energy receiving data, historical energy transmission data and historical status data corresponding to each moment to obtain a multivariate regression equation corresponding to the substation.

[0041] S206: Obtain information texture data of the substation at each target time according to each standard state data and each actual state data; wherein the information texture data is used to reflect the degree of deviation of the actual state data relative to the standard state data at the target time.

[0042] In this step, for each target moment, the information texture data of the substation at the target moment can be obtained according to the degree of deviation between the standard state data of the substation at the target moment and the actual state data of the substation at the target moment. Exemplarily, the information texture data can be the difference between the standard state data and the actual state data at the same target moment.

[0043] In an example, the present application may also generate a correspondence between the identifier of the substation, the target time, and the information texture data corresponding to the target time, so as to mark the substation identifier of the substation in each information texture data.

[0044] S208: In response to the synchronization trigger instruction, information synchronization is performed with other substations based on the information texture data of the substation at each target time.

[0045] In this step, due to the energy interaction between different substations, the actual energy transmission data and actual energy reception data of this substation are correlated with the actual energy transmission data and actual energy reception data of other substations, and the multivariate regression equation corresponding to this substation describes the correspondence between the energy transmission data, energy reception data and status data of this substation. Therefore, the synchronization of substation information can be achieved based on the information texture data at each target time.

[0046] Furthermore, in one example, when it is necessary to synchronize substation information, the substation can also synchronize information with other substations based on the multivariate regression equation corresponding to the substation and the information texture data of the substation at each target time.

[0047] It can be understood that the generation of the synchronization trigger instruction of the present application can be determined according to the actual situation, for example, it can be generated in response to manual operation, or generated when the preset synchronization rules are met, and this document does not impose specific restrictions on this. For example, the substation can periodically generate a synchronization trigger instruction according to a preset cycle length to synchronize the substation information within the latest synchronization cycle.

[0048] In one embodiment, the actual state data includes actual indicator data corresponding to multiple state monitoring indicators, and the standard state data includes standard indicator data corresponding to multiple state monitoring indicators. In this article, multiple can be understood as two or more, for example, multiple state monitoring indicators may include temperature indicators, voltage indicators, power indicators, current indicators, etc. Taking the temperature indicator as an example, the actual indicator data corresponding to the temperature indicator may be the actual temperature value collected by the temperature sensor, and the standard indicator data corresponding to the temperature indicator may be the standard temperature value calculated based on the multivariate regression equation.

[0049] According to each standard state data and each actual state data, the information texture data of the substation at each target time is obtained, including:

[0050] Step B11: for each of the multiple state monitoring indicators, calculating the difference between the actual indicator data corresponding to the state monitoring indicator and the standard indicator data corresponding to the state monitoring indicator at each target time;

[0051] Step B12: For each target moment, the differences corresponding to the multiple status monitoring indicators at the target moment are combined according to a preset combination order, and the information texture data of the substation at the target moment is obtained.

[0052] In this embodiment, when there are multiple state monitoring indicators, each state monitoring indicator can be calculated based on its corresponding actual indicator data and standard indicator data to obtain the difference of the state monitoring indicator at each target time. This application can combine the differences of various state monitoring indicators at the same time in a preset combination order to obtain the information texture data of this substation at each target time.

[0053] For example, when the state monitoring index includes a temperature index and a voltage index, and the target moments are the first moment and the second moment respectively, the present application can calculate the first difference between the actual temperature value and the standard temperature value at the first moment, the second difference between the actual voltage value and the standard voltage value at the first moment, the third difference between the actual temperature value and the standard temperature value at the second moment, and the fourth difference between the actual voltage value and the standard voltage value at the second moment. The present application can combine the first difference with the second difference to obtain the information texture data at the first moment. Similarly, the third difference can be combined with the fourth difference to obtain the information texture data at the second moment. In this way, transmission can be facilitated to avoid information loss.

[0054] In one embodiment, according to each standard state data and each actual state data, information texture data of the substation at each target time is obtained, which may include:

[0055] Step B21: according to the condition monitoring index, matching the actual index curve under the same condition monitoring index with the standard index curve, and mapping each actual index curve and each standard index curve in pairs on a two-dimensional coordinate system;

[0056] Step B22: determining n real-time indicator data at each actual indicator curve and n standard indicator data at each standard indicator curve through n target moments;

[0057] Step B23: Calculate the error between the real-time indicator data and the standard indicator data of the same state monitoring indicator at the same target time, and combine the errors corresponding to the various state monitoring indicators at the same target time into the information texture data at the target time;

[0058] Step B24: Integrate the information texture data corresponding to each target moment in the current cycle, obtain the information texture data of the substation in the current cycle, and mark the identity of the substation.

[0059] In one embodiment, based on the information texture data of the substation at each target time, information synchronization is performed with other substations, including:

[0060] Step C11: Obtain the energy interaction record corresponding to the substation.

[0061] The energy interaction record corresponding to the substation records the energy interaction data between the substation and other substations. In this application, the energy interaction process may include the process of the substation transmitting energy to other substations, and the process of other substations transmitting energy to the substation.

[0062] Specifically, the energy interaction record may include the interaction start and end time corresponding to each energy interaction process, the identifier of the first substation, and the identifier of the second substation. Among them, the first substation is the substation that provides energy, and the second substation is the substation that receives energy. It can be understood that for each energy interaction process, if this substation transmits energy to other substations during this energy interaction process, then this substation is the first substation of this energy interaction process, and the substation that receives energy is the second substation. Similarly, if other substations transmit energy to this substation during this energy interaction process, then this substation is the second substation of this energy interaction process, and the substation that provides energy to this substation is the first substation of this energy interaction process.

[0063] Step C12: For each energy interaction process, determine the identifier of the interactive substation according to the energy interaction record, and send a first information synchronization request to the interactive substation based on the target interaction start and end times corresponding to the interactive substation and the identifier of the interactive substation, wherein the interactive substation is the substation that performs energy interaction with this substation during the energy interaction process.

[0064] In this step, for each energy interaction process in which this substation participates, this substation can determine the substation identification that interacts with this substation in this energy interaction process according to the energy interaction record, and obtain the identification of the interacting substation. It can be understood that for each energy interaction process, if this substation is the first substation in this energy interaction process, the interacting substation can be the second substation in this energy interaction process. Similarly, if this substation is the second substation in this energy interaction process, the interacting substation can be the first substation in this energy interaction process.

[0065] For each energy interaction process in which this substation participates, after determining the identifier of the interactive substation, a first information synchronization request may be sent to the interactive substation according to the interaction start and end times corresponding to this energy interaction process (i.e., the target interaction start and end times described in the embodiment of this article) and the identifier of the interactive substation. The first information synchronization request is used to instruct the interactive substation to return the information texture data of the interactive substation corresponding to the target interaction start and end times to this substation.

[0066] In one example, the information texture data of the interactive substation corresponding to the target interaction start and end time may be the information texture data of the interactive substation at the target interaction start and end time, or may be each information texture data of the interactive substation in each interaction time period. Each interaction time period may be determined according to the target interaction start and end time.

[0067] Step C13: for each energy interaction process, receiving the synchronization information texture data sent by the interactive substation in response to the first information synchronization request, generating and saving the synchronization correspondence between the interactive substation identifier, the target interaction start and end time and the synchronization information texture data.

[0068] The synchronous information texture data is the information texture data of the interactive substation corresponding to the start and end time of the target interaction.

[0069] In this step, when the interactive substation receives the first information synchronization request sent by the interactive substation, it can return the information texture data of the interactive substation corresponding to the target interaction start and end time to the interactive substation, that is, return the synchronous information texture data to the interactive substation. The interactive substation can obtain the information texture data of the interactive substation by receiving the data sent by the interactive substation, and can generate the synchronous correspondence between the identification of the interactive substation, the target interaction start and end time and the synchronous information texture data, and save the synchronous correspondence, so that the interactive substation can save the substation information of other substations and realize the substation information synchronization.

[0070] Furthermore, in an example, the substation may generate or update the real-time status information tree of the substation according to each synchronization correspondence, so as to reflect the information synchronization status between substations through the real-time status information tree.

[0071] In this embodiment, substation information synchronization can be performed according to the energy flow direction between substations and the information texture data of the substations. In this way, the accuracy of substation information synchronization can be improved, and the same information texture data can be avoided in different substations corresponding to different times.

[0072] In one embodiment, based on the information texture data of the substation at each target time, information synchronization is performed with other substations, further comprising:

[0073] Step C14: For each energy interaction process, in each information texture data of the substation, the target information texture data corresponding to the start and end time of the target interaction is determined, and the corresponding relationship between the target information texture data and the identifier of the interactive substation is generated and saved.

[0074] In this embodiment, for each energy interaction process, the substation can determine the information texture data of the substation corresponding to the start and end time of the target interaction (i.e., determine the target information texture data), and generate a corresponding relationship between the target information texture data and the identifier of the interactive substation, so as to mark the identifier of the interactive substation in the target information texture data. In this way, when receiving the second information synchronization request sent by the interactive substation, the substation can quickly determine the information texture data corresponding to the interactive substation and send it to the interactive substation, thereby further improving the synchronization efficiency.

[0075] In one embodiment, the energy interaction record also includes energy transmission data of the first substation and energy reception data of the second substation. For example, if in a certain energy interaction record, the substation provides energy with a power of P1 to substation A and provides energy with a power of P2 to substation B, then the energy transmission data recorded in the energy interaction record may be (P1+P2), and the energy reception data may be: the identifier of substation A—P1, the identifier of substation B—P2.

[0076] For each energy interaction process, the synchronization correspondence between the identification of the interactive substation, the target interaction start and end time, and the synchronization information texture data is generated and saved, including:

[0077] For each energy interaction process, if the current substation transmits energy to multiple interactive substations at the same time, or the current substation receives energy transmitted by multiple interactive substations at the same time, the energy distribution weight corresponding to each interactive substation is determined according to the energy transmission data and / or energy reception data, and the synchronization correspondence of each interactive substation is generated and saved.

[0078] The synchronization correspondence of each interactive substation is the correspondence between the energy allocation weight corresponding to the interactive substation, the identifier of the interactive substation, the target interaction start and end time, and the synchronization information texture data sent by the interactive substation.

[0079] In this embodiment, if the substation performs energy transmission operations with two or more substations at the same time, the energy distribution weight corresponding to each interactive substation can be determined according to the energy reception data of each interactive substation, and a synchronous correspondence relationship can be generated based on the energy distribution weight.

[0080] For example, in the above example, if P1:P2=1:2, the synchronization correspondence between the identifier of substation A, the target interaction start and end time, the synchronization information texture corresponding to substation A, and 1 / 3 can be generated, and the synchronization correspondence between the identifier of substation B, the target interaction start and end time, the synchronization information texture corresponding to substation B, and 2 / 3 can be generated, and the two synchronization correspondences are saved in the substation. Further, in one example, the synchronization correspondence can also include the identifier of the substation.

[0081] Similarly, if this substation simultaneously receives energy sent by two or more substations at the same time, it can determine the energy distribution weight corresponding to each interactive substation according to the energy transmission data of each interactive substation, and generate a synchronous correspondence based on the energy distribution weight.

[0082] In this embodiment, substation information synchronization can be performed more accurately according to the energy flow direction and energy distribution weight.

[0083] In one example, the present application can combine the event timeline to synchronize substation information. Specifically, based on the information texture data of the substation at each target time, information synchronization with other substations can include:

[0084] Step C21: Obtain the energy interaction record corresponding to this substation.

[0085] Step C22: According to the interaction start and end time, energy transmission data and energy reception data of each energy interaction process, the identification of this substation and the identification of the interacting substation are marked in the information texture data corresponding to the interaction start and end time of this substation, and the identification of this substation and the identification of the interacting substation are marked in the information texture data corresponding to the interaction start and end time of the interacting substation.

[0086] Step C23: Taking the substation node corresponding to this substation as the central node, according to the energy interaction record corresponding to this substation, the interaction start and end times corresponding to each energy interaction process are mapped in the event timeline of this substation, and according to the energy transmission data and energy reception data corresponding to each energy interaction process, a connecting line is set between the substation node corresponding to this substation and the substation node corresponding to the interactive substation.

[0087] The connection line may include a transmission connection line and a receiving connection line. The transmission connection line is used to describe the process of energy transmission from the substation to other substations, and the receiving connection line is used to describe the process of energy transmission from other substations to the substation. Both the transmission connection line and the receiving connection line have arrows pointing to them, and the life cycle length of the connection line is consistent with the interaction duration of the energy interaction process.

[0088] Step C24: According to the connection results between each substation node and the life cycle of the connection line, the substation number of the interactive substation connected to the central node is synchronously marked on the event timeline. The substation number can be obtained by arranging the substations in sequence according to their actual geographical location distribution.

[0089] Step C25: According to the event timeline corresponding to this substation, obtain the information texture data of the interactive substation marked with the identification of this substation from the interactive substation, and mark the corresponding interaction start and end time in the obtained information texture data of the interactive substation, so as to obtain the real-time status information tree corresponding to this substation.

[0090] In one example, in the real-time status information tree corresponding to the substation, except for the substation node corresponding to the substation, other substation nodes may appear or disappear with the time change on the event timeline.

[0091] In one embodiment, the remote communication-based substation information synchronization verification method of the present application may also include:

[0092] In response to the verification trigger instruction, for each synchronization correspondence relationship saved in the substation, the identifier of the interaction substation to be queried and the start and end times of the interaction to be queried are determined according to the synchronization correspondence relationship;

[0093] For each synchronization correspondence relationship saved in this substation, a data query request is sent to the interactive substation to be queried according to the identifier of the interactive substation to be queried and the start and end times of the interaction to be queried, and the verification information texture data returned by the interactive substation to be queried in response to the data query request is received, and verification is performed based on the verification information texture data and the synchronization information texture data of the synchronization correspondence relationship.

[0094] It is understood that the generation of the verification trigger instruction can be determined according to the actual situation, for example, it can be generated in response to manual operation, or generated when the preset verification rules are met, and this document does not impose specific restrictions on this. For example, the substation can periodically generate the verification trigger instruction according to the preset cycle time to periodically perform information verification.

[0095] Specifically, when verifying the substation information, the substation can verify whether the information in each synchronization correspondence relationship saved by the substation is accurate. Specifically, for each synchronization correspondence relationship saved by the substation, the substation can perform the following steps:

[0096] Step D11: According to the synchronous correspondence, determine the identifier of the interactive substation to be queried and the interactive start and end times to be queried. The identifier of the interactive substation to be queried is the identifier of the interactive substation in the synchronous correspondence. The interactive start and end times to be queried are the target interactive start and end times in the synchronous correspondence.

[0097] Step D12: Send a data query request to the interactive substation to be queried according to the identifier of the interactive substation to be queried and the start and end time of the interaction to be queried. The data query request is used for the interactive substation to return the information texture data of the interactive substation to be queried at the start and end time of the interaction to be queried to this substation.

[0098] Step D13: receiving the verification information texture data returned by the interactive substation to be queried in response to the data query request, and verifying the verification information texture data and the synchronization information texture data of the synchronization correspondence. By comparing the verification information texture data returned by the interactive substation to be queried with the synchronization information texture data in the synchronization correspondence, the synchronization correspondence can be verified.

[0099] In this embodiment, the information texture data of each substation may be mapped to each other to complete the substation information verification, thereby ensuring the integrity and accuracy of the substation information.

[0100] In one embodiment, for each synchronization correspondence stored in the substation, verification is performed based on the verification information texture data and the synchronization information texture data of the synchronization correspondence, including:

[0101] Step D21: For each synchronization correspondence stored in the substation, if the verification information texture data is consistent with the synchronization information texture data of the synchronization correspondence, the verification is passed.

[0102] In this step, if the verification information texture data returned by the interactive substation to be queried is consistent with the synchronization information texture data stored in this substation, the synchronization information stored in this substation is accurate, so the verification passes and the synchronization correspondence does not need to be operated.

[0103] Step D22: For each synchronization correspondence relationship saved in this substation, if the verification information texture data is inconsistent with the synchronization information texture data of the synchronization correspondence relationship, the verification fails, and the information texture data to be synchronized of this substation at the start and end time of the interaction to be queried is generated again according to the actual monitoring data of this substation at the start and end time of the interaction to be queried, and a texture data generation request is sent to the interactive substation to be queried; wherein, the texture data generation request is used to instruct the interactive substation to be queried to regenerate the verification information texture data of the interactive substation to be queried at the start and end time of the interaction to be queried according to the information texture data of the interactive substation to be queried at the start and end time of the interaction to be queried.

[0104] In this step, if the verification information texture data returned by the interactive substation to be queried is inconsistent with the synchronization information texture data stored in this substation, it means that the synchronization information stored in this substation is inconsistent with the information stored in the interactive substation to be queried, and it is determined that the verification fails.

[0105] In this case, the present application can determine the time corresponding to the data inconsistency, and respectively retrieve the actual monitoring data of this substation and the interactive substation to be queried at that time, and regenerate the information texture data based on the retrieved actual monitoring data, and perform synchronization accordingly.

[0106] Specifically, the substation can regenerate the information texture data of the substation according to the actual monitoring data of the substation at the start and end time of the interaction to be queried, so as to obtain the information texture data to be synchronized. The substation can also send a texture data generation request to the interactive substation to be queried, so as to instruct the interactive substation to be queried to regenerate the information texture data according to the actual monitoring data of the interactive substation to be queried at the start and end time of the interaction to be queried, so as to obtain the verification information texture data.
