Description

Technical Field

[0001] This invention relates to the field of secure data transmission, and in particular to a power data transmission system based on a one-way isolation gate. Background Technology

[0002] Based on the isolation security zones and data transfer information provided by unidirectional isolation gate devices, power data leakage is effectively prevented, ensuring the security of data transmission and the stability of power equipment operation during actual power system operation. Furthermore, to ensure data integrity during unidirectional data transmission, redundant transmission processing of power data is required. In actual real-time monitoring of the power grid, power data transmission flow exhibits certain fluctuations, leading to differences in the transfer pressure on the unidirectional isolation gates and consequently, low overall power data transmission efficiency. Therefore, optimizing the data transmission process and the transfer pressure distribution of unidirectional isolation gates based on the actual operation of the power system to ensure the quality and efficiency of power data transmission is a problem urgently needing to be solved by those skilled in the art.

[0003] Chinese Patent Publication No. CN115022084A discloses a data exchange method for network isolation gateways and its application. It employs a dynamic ferry transmission algorithm: after data transmission compression in the external resource pool, the original transmission protocol is stripped, and the data is sliced. Sequence codes and integrity checks are added to the data slices. During channel connection, address pointers are allocated to select appropriate data transmission channels to achieve the maximum data flow rate for a single channel per data slice. The Laida criterion is used to detect anomalies. After data transmission and integrity checks are completed across multiple channels, data is sequentially connected according to the sequence codes to obtain a data consolidation packet. The transmission protocol is then re-encapsulated. After encapsulation, the data is decompressed, and the connection between the internal resource pool and the internal machine is established. After transmission is complete, logs are saved on the internal machine. Chinese Patent Publication No. CN104683352A discloses an industrial communication isolation gateway with dual-channel switching, including a secure end processing unit, a non-secure end processing unit, and a switching unit. The circuits of the secure end processing unit, the non-secure end processing unit, and the switching unit are all independent, and the three units communicate via USB. The switching unit employs dual-channel switching, consisting of two independent unidirectional channels. One channel is a request channel, responsible for unidirectional requests from the non-secure end to the secure end, used for configuration requests and tag requests. The other channel is a data channel, responsible for unidirectional transmission from the secure end to the non-secure end, used for process data transmission and status data transmission. However, the above technical solution has the following problems: it fails to make targeted settings for the data transmission process and the allocation and scheduling of the unidirectional isolation gateway based on the actual operating conditions of the monitored power grid system, resulting in low transmission quality and efficiency of power data. Summary of the Invention

[0004] To address this, the present invention provides a power data transmission system based on a one-way isolation gate, which overcomes the problem that existing technologies fail to make targeted settings for the data transmission process and the allocation and scheduling of the one-way isolation gate based on the actual operating conditions of the monitored power grid system, resulting in low power data transmission quality and efficiency.

[0005] To achieve the above objectives, the present invention provides a power data transmission system based on a unidirectional isolation gate, comprising:

[0006] The network gateway monitoring module is used to determine the transmission execution strategy of each transmission execution gateway based on the associated core proportion index and the associated load change index, and to perform power data transmission based on redundancy optimization processing or association optimization analysis.

[0007] A redundancy optimization module, which is connected to the network gateway monitoring module, is used to determine the redundancy processing method of a type of transmission execution network gateway based on the correlation ratio index and the core correlation index, namely, to perform aggregate redundancy analysis or core redundancy analysis on a type of processing execution network gateway.

[0008] A redundant execution module, which is connected to the redundancy optimization module, includes a first redundant execution unit and a second redundant execution unit, used to determine the redundancy processing coefficient based on the correlation index and the core index, and to determine the redundancy processing coefficient based on the equipment core index and the equipment correlation index.

[0009] The associated optimization module, which is connected to the network gateway monitoring module, is used to determine the reserved execution mode of the second type of transmission execution network gateway based on the associated load processing index, which is either based on the stage reference load index, or based on the associated load processing index and the associated core proportion index, to determine the network gateway dynamic reservation index of the second type of transmission execution network gateway.

[0010] The redundancy allocation module, which is connected to the redundancy execution module and the correlation optimization module, is used to determine the allocation processing method of the redundancy allocation gateway based on the execution correlation coefficient. This method is either based on the set correlation interaction index and the gateway dynamic reservation index to determine the allocation priority coefficient of each type II transmission execution gateway, or based on the gateway correlation index and the gateway dynamic reservation index to determine the allocation priority coefficient of each type II transmission execution gateway.

[0011] Furthermore, the gateway monitoring module periodically detects the associated core percentage index and associated load change index of each transmission execution gateway;

[0012] For a single transmission, a network gateway is executed.

[0013] The associated core proportion index is the proportion of the number of associated core devices of the transmission execution gateway in the total number of associated execution devices of the transmission execution gateway, and the associated load change index is the average value of the load change parameters of the associated execution devices of the transmission execution gateway.

[0014] Furthermore, if the monitoring and evaluation condition of the network gateway monitoring module is that the associated core ratio index of the transmission execution network gateway is greater than the preset associated core ratio index or the associated load change index is greater than the preset associated load change index, then it is determined that the transmission execution network gateway performs power data transmission based on the redundancy optimization processing method, and the transmission execution network gateway is determined to be a type of transmission execution network gateway.

[0015] Furthermore, if the monitoring and evaluation conditions responded by the network gate monitoring module are that the associated core ratio index of the transmission execution network gate is less than or equal to the preset associated core ratio index and the associated load change index is less than or equal to the preset associated load change index, then it is determined that the transmission execution network gate performs power data transmission based on the association optimization analysis method, and the transmission execution network gate is determined to be a Class II transmission execution network gate.

[0016] Furthermore, the redundancy optimization module responds to the redundancy optimization conditions and determines the redundancy processing method of a type of processing execution gateway based on the execution correlation coefficient;

[0017] The redundancy optimization module responds to the redundancy execution condition when there is an execution correlation coefficient of a certain type of processing execution gateway that is greater than the preset execution correlation coefficient. Then, it is determined that the first redundancy execution unit performs aggregated redundancy analysis for that type of processing execution gateway.

[0018] The redundancy optimization module responds to the redundancy execution condition when there is a type of processing execution gateway whose execution correlation coefficient is less than or equal to the preset execution correlation coefficient. Then, the second redundancy execution unit is determined to perform core redundancy analysis on the type of processing execution gateway.

[0019] The redundancy optimization condition is that there is a transmission execution gateway and the gateway monitoring module determines that power data transmission is performed based on the redundancy optimization processing method. The execution correlation coefficient is determined according to the correlation correlation ratio index and the core correlation index.

[0020] Furthermore, the first redundant execution unit responds to the set analysis conditions and determines the redundant analysis set based on the set correlation overlap.

[0021] The first redundant execution unit responds to the set conditions, determines the redundancy processing coefficient of each associated execution device in the redundancy analysis set according to the associated relevant index and the related core index, and determines whether to adjust the redundancy processing coefficient according to the set reference core index.

[0022] The aggregation adjustment condition for the response of the first redundant execution unit is that the set reference core index of the redundant analysis set is less than or equal to the preset set reference core index. Then, the redundancy processing coefficient of each associated execution device in the redundant analysis set is reduced according to the set reference core index.

[0023] The aggregation analysis condition is that there exists a type of transmission execution gateway that is determined by the redundancy optimization module to perform aggregation redundancy analysis, and the aggregation setting condition is that there exists a type of transmission execution gateway that completes the determination of the redundancy analysis set.

[0024] Furthermore, the second redundant execution unit responds to the core analysis conditions and determines the redundancy processing coefficient of each associated execution device of the first type of processing execution gateway based on the device core index and the device related index.

[0025] The redundancy processing coefficient is positively correlated with both the core equipment index and the related equipment index.

[0026] The core analysis condition is that there exists a type of transmission execution gateway that is determined by the redundancy optimization module for core redundancy analysis.

[0027] Furthermore, the redundancy allocation module responds to the redundancy processing completion condition and determines the allocation processing method of each redundancy allocation gateway based on the execution correlation coefficient, so as to determine the target allocation gateway of the associated execution device of each redundancy allocation gateway.

[0028] The allocation evaluation condition of the redundancy allocation module is that the execution correlation coefficient of the redundant allocation gateway is greater than the preset execution correlation coefficient. Then, the allocation priority coefficient of each type II transmission execution gateway is determined based on the set related interaction index and the gateway dynamic reservation index.

[0029] The allocation evaluation condition of the redundant allocation module is that the execution correlation coefficient of the redundant allocation gateway is less than or equal to the preset execution correlation coefficient. Then, the allocation priority coefficient of each type II transmission execution gateway is determined based on the gateway correlation index and the gateway dynamic reservation index.

[0030] The condition for completing the redundancy processing is the existence of a redundancy allocation gateway, which is a type of transmission execution gateway where the redundancy processing coefficients of all associated execution devices are set.

[0031] Furthermore, the correlation optimization module responds to the correlation optimization conditions, determines the correlation load processing index of the second-class transmission execution gateway based on the stage core proportion change index and the stage reference load change index, and determines the reserved execution mode of the second-class transmission execution gateway according to the correlation load processing index.

[0032] The correlation optimization condition is that there is a transmission execution gateway and the gateway monitoring module determines that power data transmission is performed based on the correlation optimization analysis method.

[0033] Furthermore, the reservation analysis condition for the response of the correlation optimization module is that there is a correlation load processing index of the second type of transmission execution gateway that is greater than the preset correlation load processing index. Then, the dynamic reservation index of the second type of transmission execution gateway is determined based on the correlation load processing index and the correlation core proportion index.

[0034] The reserved analysis condition for the response of the correlation optimization module is that there is a correlation load processing index of the second type of transmission execution gateway that is less than or equal to the preset correlation load processing index. Then, the dynamic reserved index of the gateway is determined based on the stage reference load index.

[0035] Compared with the prior art, the beneficial effects of the present invention are that the technical solution of the present invention determines the transmission execution strategy of each transmission execution gateway based on the associated core proportion index and the associated load change index, so as to make targeted analysis on the existing transmission execution gateways, ensuring that the processing of each transmission execution gateway is more in line with the actual working scenario, and making targeted adjustments to the redundancy processing process and transmission allocation of the transmission data of each transmission execution gateway. The present invention improves the transmission quality and transmission efficiency of power data transmission based on unidirectional isolation gateways.

[0036] Furthermore, this invention characterizes whether there is a significant risk of data transmission volume fluctuation during the data transmission process of each transmission execution gateway, as well as the importance of the transmitted power data to power system monitoring and analysis, based on the associated core proportion index and the associated load change index. For cases where the risk of data transmission volume fluctuation is large or the transmitted power data is important to power system monitoring and analysis, the redundancy processing of transmitted data during transmission is optimized. Under the premise of ensuring data transmission quality, the data transmission burden of the transmission execution gateway is effectively reduced, and this invention improves the transmission efficiency of power data transmission.

[0037] Furthermore, this invention addresses a type of transmission execution gateway with a large associated core ratio index or a large associated load change index. It employs a redundancy optimization approach for power data transmission. Specifically, the redundancy processing method is further determined based on the execution association coefficient. This ensures that the redundancy processing performed on the power data corresponding to the associated execution devices of this type of transmission execution gateway is more consistent with actual working scenarios. This ensures that the redundancy processing level for each associated execution device effectively reduces the data transmission burden of the transmission execution gateway while maintaining the effectiveness of power data transmission. This invention improves the transmission quality and efficiency of power data transmission based on a unidirectional isolation gateway.

[0038] Furthermore, in this invention, for the second-class transmission execution gateway with relatively small associated core proportion index and associated load change index, power data transmission is carried out based on the associated optimization analysis method. Since the data transmission volume of the second-class transmission execution gateway has a large risk of fluctuation and the power data it is responsible for transmitting does not have a significant impact on the power system monitoring and analysis process, the reserved execution mode is determined according to the associated load processing index, and its additional data transmission capacity is specifically evaluated to ensure the reliability of the data transmission task redistribution result, thereby improving the transmission efficiency of the power data transmission process.

[0047] Please see Figures 1 to 4 As shown, the present invention provides a power data transmission system based on a unidirectional isolation gate, comprising:

[0048] The network gateway monitoring module is used to determine the transmission execution strategy of each transmission execution gateway based on the associated core proportion index and the associated load change index, and to perform power data transmission based on redundancy optimization processing or association optimization analysis.

[0049] A redundancy optimization module, which is connected to the network gateway monitoring module, is used to determine the redundancy processing method of a type of transmission execution network gateway based on the correlation ratio index and the core correlation index, namely, to perform aggregate redundancy analysis or core redundancy analysis on a type of processing execution network gateway.

[0050] A redundant execution module, which is connected to the redundancy optimization module, includes a first redundant execution unit and a second redundant execution unit, used to determine the redundancy processing coefficient based on the correlation index and the core index, and to determine the redundancy processing coefficient based on the equipment core index and the equipment correlation index.

[0051] The associated optimization module, which is connected to the network gateway monitoring module, is used to determine the reserved execution mode of the second type of transmission execution network gateway based on the associated load processing index, which is either based on the stage reference load index, or based on the associated load processing index and the associated core proportion index, to determine the network gateway dynamic reservation index of the second type of transmission execution network gateway.

[0052] The redundancy allocation module, which is connected to the redundancy execution module and the correlation optimization module, is used to determine the allocation processing method of the redundancy allocation gateway based on the execution correlation coefficient. This method is either based on the set correlation interaction index and the gateway dynamic reservation index to determine the allocation priority coefficient of each type II transmission execution gateway, or based on the gateway correlation index and the gateway dynamic reservation index to determine the allocation priority coefficient of each type II transmission execution gateway.

[0053] This invention relates to a power transmission process based on a unidirectional isolation gate. The area requiring power transmission is designated as the target monitoring area. Within this target monitoring area, there are several transmission execution gates and several target monitoring devices. The target monitoring devices are power devices within the target monitoring area whose operational data requires continuous monitoring and transmission. Each transmission execution gate is a unidirectional isolation gate that needs to transmit power data. Each transmission execution gate is equipped with its own associated execution device. For a single transmission execution gate, if it needs to transmit the operational data of a target monitoring device, that target monitoring device is designated as its associated execution device. The categories of target monitoring devices in this invention include, but are not limited to, generators, transformers, transmission lines, and motors. However, the categories of target monitoring devices in this invention do not include switchgear, busbars, grounding equipment, and protection devices used for controlling, distributing, or protecting power systems.

[0054] This invention utilizes several transmission optimization records. Each transmission optimization record records at least one redundant processing process for transmission data of each transmission execution gateway within the target monitoring area, as well as the equipment core index, associated core ratio index, associated load change index, execution correlation coefficient, equipment correlation coefficient, set correlation overlap, set reference core index, redundancy processing coefficient, and associated load processing index during the transmission allocation process. Each transmission optimization record also has a corresponding qualification mark, which records whether the transmission quality and efficiency of power data within the target monitoring area meet user requirements. It is understood that users can determine whether the transmission quality and efficiency of power data within the target monitoring area meet their requirements based on self-defined indicators. For example, self-defined indicators may include, but are not limited to, the transmission delay index, which is the average time required to complete each data transmission.

[0055] Specifically, the gateway monitoring module periodically detects the associated core proportion index and associated load change index of each transmission execution gateway;

[0056] For a single transmission, a network gateway is executed.

[0057] The associated core proportion index is the proportion of the number of associated core devices of the transmission execution gateway in the total number of associated execution devices of the transmission execution gateway, and the associated load change index is the average value of the load change parameters of the associated execution devices of the transmission execution gateway.

[0058] In this invention, an execution evaluation cycle is applied, the duration of which can be determined by the user. The higher the user's requirements for the transmission quality and efficiency of power data within the target monitoring area, the shorter the execution evaluation cycle. A value for the duration of the execution evaluation cycle is provided, which is 30 minutes. At the end of each execution evaluation cycle, the load change parameters and core index of the associated execution devices of each transmission execution gateway are detected to determine the associated core proportion index and associated load change index of each transmission execution gateway. Based on the associated core proportion index and associated load change index, the transmission execution strategy of each transmission execution gateway in the next execution evaluation cycle of the current execution evaluation cycle is determined.

[0059] If the current time is the end time of an execution evaluation cycle, this execution evaluation cycle is recorded as the target evaluation cycle, and the next execution evaluation cycle is recorded as the target analysis cycle. The associated core proportion index and associated load change index of each transmission execution gateway are detected to determine the transmission execution strategy of each transmission execution gateway within the target analysis cycle. The associated core proportion index = the number of associated core devices of the transmission execution gateway / the number of associated execution devices of the transmission execution gateway. The associated core device is the associated execution device whose device core index is greater than a preset device core index. For a single associated execution device, the device core index is... The average of the operating load rate determined in each period within the target evaluation cycle, wherein the load change parameter is the sum of the core floating index and the core change magnitude, wherein the core floating index = the standard deviation of the operating load rate determined for the associated execution device in each period within the target evaluation cycle / the average of the operating load rate determined for the associated execution device in each period within the target evaluation cycle, and the core change magnitude = |the core index of the device determined for the associated execution device in the target evaluation cycle - the core index of the device determined for the associated execution device in the previous execution evaluation cycle of the target evaluation cycle| / the core index of the device determined for the associated execution device in the previous execution evaluation cycle of the target evaluation cycle;

[0060] The value of the preset equipment core index can be determined by the user according to the actual working scenario. For example, the user can set it according to the transmission optimization record. The higher the user's requirements for the transmission quality and transmission efficiency of power data in the target supervision area, the smaller the value of the preset equipment core index. A method for determining the value of the preset equipment core index is provided, which is the average value of the equipment core index of each associated core device in the transmission optimization record that meets the user's requirements for the transmission quality and transmission efficiency of power data in the target supervision area.

[0061] This invention applies a load monitoring cycle, the duration of which can be determined by the user. The higher the user's requirements for the transmission quality and efficiency of power data within the target monitoring area, the shorter the load monitoring cycle. A load monitoring cycle duration of 5 minutes is provided. At the end of each load monitoring cycle, the operating load rate of each key execution device is detected. For a single key execution device, the operating load rate = the actual operating power obtained by the key execution device at the end of the corresponding load monitoring cycle / the rated maximum power of the key execution device. How to determine the operating load rate of each category of key execution devices is a matter well understood by those skilled in the art and will not be elaborated here.

[0062] Specifically, the monitoring and evaluation conditions responded by the network gateway monitoring module are as follows: if the associated core ratio index of the transmission execution network gateway is greater than the preset associated core ratio index or the associated load change index is greater than the preset associated load change index, then it is determined that the transmission execution network gateway is performing power data transmission based on the redundancy optimization processing method, and the transmission execution network gateway is determined to be a type of transmission execution network gateway.

[0063] Specifically, the monitoring and evaluation conditions responded by the network gate monitoring module are as follows: if the associated core ratio index of the transmission execution network gate is less than or equal to the preset associated core ratio index and the associated load change index is less than or equal to the preset associated load change index, then it is determined that the transmission execution network gate performs power data transmission based on the association optimization analysis method, and the transmission execution network gate is determined to be a Class II transmission execution network gate.

[0064] The values ​​of the preset associated core proportion index and the preset associated load change index can be determined by the user based on the actual working scenario. For example, the user can set them based on transmission optimization records. The higher the user's requirements for the transmission quality and efficiency of power data within the target monitoring area, the smaller the value of the preset associated core proportion index and the preset associated load change index. A method for determining the value of the preset associated core proportion index is provided, in which the transmission optimization records of power data transmission based on the association optimization analysis method are recorded as evaluation reference records, and the maximum value of the associated core proportion index in the evaluation reference records that meet the user's requirements for the transmission quality and efficiency of power data within the target monitoring area is recorded as the preset associated core proportion index. A method for determining the value of the preset associated load change index is provided, in which the maximum value of the associated load change index in the evaluation reference records that meet the user's requirements for the transmission quality and efficiency of power data within the target monitoring area is recorded as the preset associated load change index.

[0065] Specifically, the redundancy optimization module responds to redundancy optimization conditions and determines the redundancy processing method of a processing execution gateway based on the execution correlation coefficient;

[0066] The redundancy optimization module responds to the redundancy execution condition when there is an execution correlation coefficient of a certain type of processing execution gateway that is greater than the preset execution correlation coefficient. Then, it is determined that the first redundancy execution unit performs aggregated redundancy analysis for that type of processing execution gateway.

[0067] The redundancy optimization module responds to the redundancy execution condition when there is a type of processing execution gateway whose execution correlation coefficient is less than or equal to the preset execution correlation coefficient. Then, the second redundancy execution unit is determined to perform core redundancy analysis on the type of processing execution gateway.

[0068] The redundancy optimization condition is that there is a transmission execution gateway and the gateway monitoring module determines that power data transmission is performed based on the redundancy optimization processing method. The execution correlation coefficient is determined according to the correlation correlation ratio index and the core correlation index.

[0069] If the associated core ratio index of the processing execution gateway is greater than the preset associated core ratio index or the associated load change index is greater than the preset associated load change index, then it is determined that the transmission execution gateway performs power data transmission based on the redundancy optimization processing method, and the transmission execution gateway is recorded as a Class I transmission execution gateway. In the actual process of power data transmission, the data transmission volume of Class I transmission execution gateways has a large fluctuation risk and the importance of the transmitted power data to power system monitoring and analysis is also significant. At this time, it is necessary to optimize the redundancy processing in the data transmission process to reduce the data transmission burden of Class I transmission execution gateways.

[0070] For a single type-one processing execution gateway, the execution correlation coefficient is the sum of the correlation correlation ratio index and the core correlation index of the type-one processing execution gateway. The correlation correlation ratio index = the number of related execution devices of the type-one processing execution gateway / the total number of related execution devices of the type-one processing execution gateway. The core correlation index = the maximum value of the relevant device parameters of each related core device of the type-one processing execution gateway / the total number of related execution devices of the type-one processing execution gateway. For a single related core device, the relevant device parameter is the number of related execution devices that are related core devices among the related core devices of the type-one processing execution gateway.

[0071] For any two target monitoring devices, if the device correlation coefficient between the two target monitoring devices is greater than the preset device correlation coefficient, then the two target monitoring devices are recorded as a related device group, and the two target monitoring devices are determined to be related execution devices of each other. The device correlation coefficient is the sum of the change synchronization index and the topology overlap index. The change synchronization index = the number of change synchronization cycles within the target evaluation period / the number of load monitoring cycles within the target evaluation period. The change synchronization cycle is the load monitoring cycle in which the change magnitude of the operating load of the two target monitoring devices is greater than the preset operating load change magnitude. For a single load monitoring cycle, the change magnitude of the operating load of any target monitoring device = |the operating load rate obtained at the end of the load monitoring cycle - the operating load rate obtained at the end of the previous load monitoring cycle| / the operating load rate obtained at the end of the previous load monitoring cycle. The topology overlap index = the number of target monitoring devices that have a topological relationship with the two target monitoring devices at the same time / the number of different target monitoring devices that have a topological relationship with the two target monitoring devices.

[0072] The values ​​of the preset execution correlation coefficient, preset operating load change range, and preset equipment correlation coefficient can be determined by the user according to the actual working scenario. For example, the user can set them based on transmission optimization records. The higher the user's requirements for the transmission quality and efficiency of power data within the target monitoring area, the smaller the value of the preset operating load change range. A method for determining the preset execution correlation coefficient is provided, in which the transmission optimization record for aggregated redundancy analysis of a type of processing execution gateway is recorded as the correlation reference record, and the average value of the execution correlation coefficients of each type of processing execution gateway in the correlation reference record that meets the user's requirements for the transmission quality and efficiency of power data within the target monitoring area is recorded as the preset execution correlation coefficient. A value for the preset operating load change range is provided, which is 0.1. A method for determining the preset equipment correlation coefficient is provided, in which the average value of the equipment correlation coefficients between two related execution devices included in each related equipment group in the transmission optimization record that meets the user's requirements for the transmission quality and efficiency of power data within the target monitoring area is recorded as the preset equipment correlation coefficient.

[0073] Specifically, the first redundant execution unit responds to the set analysis conditions and determines the redundant analysis set based on the set correlation overlap.

[0074] The first redundant execution unit responds to the set conditions, determines the redundancy processing coefficient of each associated execution device in the redundancy analysis set according to the associated relevant index and the related core index, and determines whether to adjust the redundancy processing coefficient according to the set reference core index.

[0075] The aggregation adjustment condition for the response of the first redundant execution unit is that the set reference core index of the redundant analysis set is less than or equal to the preset set reference core index. Then, the redundancy processing coefficient of each associated execution device in the redundant analysis set is reduced according to the set reference core index.

[0076] The aggregation analysis condition is that there exists a type of transmission execution gateway that is determined by the redundancy optimization module to perform aggregation redundancy analysis, and the aggregation setting condition is that there exists a type of transmission execution gateway that completes the determination of the redundancy analysis set.

[0077] Specifically, for a single Class I processing execution gateway, if the execution correlation coefficient of the Class I processing execution gateway is greater than the preset execution correlation coefficient, it indicates that the correlation between the associated execution devices of the Class I processing execution gateway is relatively high, and there are many related execution devices among the core associated devices. This indicates that when analyzing the power system of the target regulatory area based on the completed power data, there is a high correlation between the power data that the associated execution devices need to transmit, and there are relatively many associated execution devices that can be affected by the core associated devices. Therefore, by grouping the associated execution devices of the Class I processing execution gateway, the correlation between power data is taken into account during the redundancy process, thereby ensuring the transmission quality of power data.

[0078] The set correlation overlap of any redundancy analysis set is greater than the preset set correlation overlap. For a single redundancy analysis set, the set correlation overlap is the average correlation overlap of each associated execution device in the redundancy analysis set. For a single associated execution device, the correlation overlap = the number of overlapping associated devices of the associated execution device / the number of associated execution devices of the associated execution device. If an associated execution device is simultaneously associated with two or more associated execution devices in the redundancy analysis set, then the associated execution device is recorded as an overlapping associated device.

[0079] The value of the preset set correlation overlap can be determined by the user according to the actual working scenario. For example, the user can set it according to the transmission optimization record. The higher the user's requirements for the transmission quality and transmission efficiency of power data in the target supervision area, the larger the value of the preset set correlation overlap. A method for determining the value of the preset set correlation overlap is provided, which is to record the average value of the set correlation overlap of each redundancy analysis set in the transmission optimization record that meets the user's requirements for the transmission quality and transmission efficiency of power data in the target supervision area as the preset set correlation overlap.

[0080] For a single redundancy analysis set, the redundancy processing coefficient and processing reference coefficient of any associated execution device within the set are positively correlated. The processing reference coefficient is the sum of the association correlation index and the correlation core index of the associated execution device. The association correlation index = the number of associated execution devices within the redundancy analysis set / the total number of associated execution devices within the set. The correlation core index = the number of correlation core devices among the overlapping associated devices of the associated execution device / the total number of overlapping associated devices of the associated execution device. The set reference core index is the average of the device core indices of all associated execution devices within the redundancy analysis set. If the set reference core index of the redundancy analysis set is less than or equal to the set reference core index, then for that... The redundancy processing coefficients of each associated execution device within the redundancy analysis set are reduced. The reduction in the redundancy processing coefficient is negatively correlated with the set reference core index. If the set reference core index of the redundancy analysis set is less than or equal to the set reference core index, it indicates that the device core indexes of the associated execution devices within the redundancy analysis set are generally small. The operation of each associated execution device in the redundancy analysis set is likely to affect the operation of other associated execution devices within the redundancy analysis set. However, if the device core indexes are generally small, it indicates that the influence of the associated execution devices within the redundancy analysis set is relatively low. Therefore, the redundancy processing coefficients of each associated core device within the redundancy analysis set are adjusted as a whole to avoid excessive redundancy processing for such redundancy analysis sets.

[0081] The preset set reference core index can be determined by the user according to the actual working scenario. For example, the user can set it according to the transmission optimization record. The higher the user's requirements for the transmission quality and transmission efficiency of power data in the target supervision area, the smaller the value of the preset set reference core index. A method for determining the value of the preset set reference core index is provided. The transmission optimization record that reduces the redundancy processing coefficient of each associated execution device in the redundancy analysis set according to the set reference core index is recorded as the set control reference record. The maximum value of the set reference core index of each redundancy analysis set in the set control reference record that meets the user's requirements for the transmission quality and transmission efficiency of power data in the target supervision area is recorded as the preset set reference core index.

[0082] In the process of power data transmission, redundancy processing is an important technical means to ensure the integrity and reliability of data. The redundancy processing coefficient reflects the degree of redundancy processing of the equipment operation data of each target monitoring device. For a single target monitoring device, the redundancy processing coefficient = the amount of data added after redundancy processing compared to the original data amount / the original data amount, where the original data amount is the actual amount of data that the target monitoring device needs to transmit.

[0083] Specifically, the second redundant execution unit responds to the core analysis conditions and determines the redundancy processing coefficient of each associated execution device of the first type of processing execution gateway based on the device core index and the device related index.

[0084] The redundancy processing coefficient is positively correlated with both the core equipment index and the related equipment index.

[0085] The core analysis condition is that there exists a type of transmission execution gateway that is determined by the redundancy optimization module for core redundancy analysis.

[0086] Specifically, for a single Class I processing execution gateway, if the execution correlation coefficient of the Class I processing execution gateway is less than or equal to the preset execution correlation coefficient, it indicates that the correlation between the associated execution devices of the Class I processing execution gateway is small, and there are relatively few related execution devices among the core associated devices. This further indicates that when analyzing the power system of the target regulatory area based on the completed power data transmission, the correlation between the power data that the associated execution devices need to transmit is weak, and there are relatively few related execution devices that can be affected by the core associated devices. Therefore, it is only necessary to independently analyze the importance of the operation of each associated execution device to determine the redundancy processing coefficient. For any associated execution device of a Class I processing execution gateway whose execution correlation coefficient is less than or equal to the preset execution correlation coefficient, the redundancy processing coefficient is positively correlated with the device reference index. The device reference index is the sum of the device core index and the device correlation index, and the device correlation index is the number of related execution devices present in the associated execution device.

[0087] Specifically, the redundancy allocation module responds to the redundancy processing completion condition and determines the allocation processing method of each redundancy allocation gateway based on the execution correlation coefficient, so as to determine the target allocation gateway of the associated execution device of each redundancy allocation gateway.

[0088] The allocation evaluation condition of the redundancy allocation module is that the execution correlation coefficient of the redundant allocation gateway is greater than the preset execution correlation coefficient. Then, the allocation priority coefficient of each type II transmission execution gateway is determined based on the set related interaction index and the gateway dynamic reservation index.

[0089] The allocation evaluation condition of the redundant allocation module is that the execution correlation coefficient of the redundant allocation gateway is less than or equal to the preset execution correlation coefficient. Then, the allocation priority coefficient of each type II transmission execution gateway is determined based on the gateway correlation index and the gateway dynamic reservation index.

[0090] The condition for completing the redundancy processing is the existence of a redundancy allocation gateway, which is a type of transmission execution gateway where the redundancy processing coefficients of all associated execution devices are set.

[0091] The target allocation gateway is a type II transmission execution gateway used to transmit the operating data of some associated execution devices of the redundant allocation gateway. The allocation processing method is determined according to the execution association coefficient to ensure that the determination result of the allocation execution gateway is more in line with the actual working scenario, thereby ensuring the effectiveness of the re-allocation decision for power data transmission tasks.

[0092] For a single redundant allocation gateway, if the execution correlation coefficient of the redundant allocation gateway is greater than a preset execution correlation coefficient, a target allocation gateway is determined for each redundancy analysis set of the redundant allocation gateway. For a single redundancy analysis set, the allocation priority coefficient of each type II transmission execution gateway is determined based on the set correlation interaction index and the gateway dynamic reservation index. For a single type II transmission execution gateway, the allocation priority coefficient is the product of the set correlation interaction index and the gateway dynamic reservation index. The set correlation interaction index = the average of the correlation interaction indices of each associated execution device in the redundancy analysis set / the number of associated execution devices of the type II transmission execution gateway. For any associated execution device in the redundancy analysis set, the correlation interaction index is the number of associated execution devices of the type II transmission execution gateway. The type II transmission execution gateway with the largest allocation priority coefficient is designated as the target for each associated execution device in the redundancy analysis set. The allocation gateway is responsible for transmitting the device operation data of each associated execution device within the redundancy analysis set during the target evaluation period. If the execution correlation coefficient of the redundancy allocation gateway is less than or equal to the preset execution correlation coefficient, a target allocation gateway is determined for each associated execution device of the redundancy allocation gateway. For a single associated execution device, the allocation priority coefficient of each type II transmission execution gateway is determined based on the gateway correlation index and the gateway dynamic reservation index. For a single type II transmission execution gateway, the allocation priority coefficient is the product of the gateway correlation index and the gateway dynamic reservation index. The gateway correlation index = the number of associated execution devices of the associated execution device among the associated execution devices of the type II transmission execution gateway / the number of associated execution devices of the type II transmission execution gateway. The type II transmission execution gateway with the largest allocation priority coefficient is recorded as the target allocation gateway of the associated execution device and is responsible for transmitting the device operation data of the associated execution device during the target evaluation period.

[0093] Specifically, the correlation optimization module responds to the correlation optimization conditions, determines the correlation load processing index of the second-class transmission execution gateway based on the phase core proportion change index and the phase reference load change index, and determines the reserved execution mode of the second-class transmission execution gateway according to the correlation load processing index.

[0094] The correlation optimization condition is that there is a transmission execution gateway and the gateway monitoring module determines that power data transmission is performed based on the correlation optimization analysis method.

[0095] Specifically, the reservation analysis condition of the correlation optimization module response is that there is a correlation load processing index of the second type of transmission execution gateway that is greater than the preset correlation load processing index. Then, the dynamic reservation index of the second type of transmission execution gateway is determined based on the correlation load processing index and the correlation core proportion index.

[0096] The reserved analysis condition for the response of the correlation optimization module is that there is a correlation load processing index of the second type of transmission execution gateway that is less than or equal to the preset correlation load processing index. Then, the dynamic reserved index of the gateway is determined based on the stage reference load index.

[0097] Specifically, for a single Class II transmission execution gateway, the associated load processing index is the sum of the stage core proportion change index and the stage reference load change index. The stage core proportion change index = the standard deviation of the associated core proportion index determined by the Class II transmission execution gateway for each execution evaluation cycle within the reserved evaluation stage / the average value of the associated core proportion index determined by the Class II transmission execution gateway for each execution evaluation cycle within the reserved evaluation stage. The stage reference load change index is the average value of the associated load change index determined by the Class II transmission execution gateway for each execution evaluation cycle within the reserved evaluation stage. The end time of the reserved evaluation stage is the start time of the target analysis cycle. The duration of the reserved evaluation stage can be set by the user according to the actual working scenario, providing a value for the duration of the reserved evaluation stage, which is ten times the duration of the execution evaluation cycle.

[0098] For Class II transmission execution gateways, power data transmission is performed based on correlation optimization analysis. Instead of setting redundancy processing coefficients for each associated execution device of the Class II transmission execution gateway, a preset redundancy processing coefficient is used to ensure data transmission quality. The value of the preset redundancy processing coefficient can be determined by the user based on the actual working scenario. For example, the user can set it based on transmission optimization records. The higher the user's requirements for the transmission quality and efficiency of power data within the target monitoring area, the larger the value of the preset redundancy processing coefficient. A method for determining the preset redundancy processing coefficient is provided, which takes the average value of the redundancy processing coefficients of each associated execution device of the Class II transmission execution gateway in the transmission optimization records that meet the user's requirements for the transmission quality and efficiency of power data within the target monitoring area as the preset redundancy processing coefficient.

[0099] The reserved execution mode of the Class II transmission execution gateway is determined based on the associated load processing index. The associated load processing index characterizes the stability of the operating load of the associated execution equipment during the reservation assessment phase, thus representing the data transmission volume fluctuation risk of the Class II transmission execution gateway. For a single Class II transmission execution gateway, if the associated load processing index is greater than the preset associated load processing index, it indicates that the operation and data transmission stability of the associated execution equipment of the Class II transmission execution gateway are poor. The associated load processing index and the associated core proportion index characterize the risk of data transmission fluctuations over longer and shorter time periods, thereby determining the gateway's dynamic reservation index. The gateway's dynamic reservation index is related to the reservation parameters. The reference index is negatively correlated with the associated load processing index and the associated core proportion index of the two types of transmission execution gateways. If the associated load processing index of the two types of transmission execution gateways is less than or equal to the preset associated load processing index, it indicates that the operation of the associated execution equipment of the two types of transmission execution gateways and the stability of data transmission are good. Therefore, the phase reference load index is used to characterize the data transmission burden of the two types of transmission execution gateways over a longer period of time, and then the dynamic reservation index of the gateway is determined. The dynamic reservation index of the gateway is negatively correlated with the phase reference load index. The phase reference load index is the average value of the equipment core index determined for each associated execution equipment of the two types of transmission execution gateways in each execution evaluation cycle within the reservation evaluation phase.

[0100] The value of the preset associated load processing index can be determined by the user according to the actual working scenario. For example, the user can set it according to the transmission optimization record. A method for determining the value of the preset associated load processing index is provided, in which the transmission optimization record that determines the dynamic reservation index of the second type of transmission execution gateway based on the stage reference load index is recorded as the reservation reference record, and the average value of the associated load processing index of each second type of transmission execution gateway in the reservation reference record that meets the user's requirements for the transmission quality and transmission efficiency of power data in the target supervision area is recorded as the preset associated load processing index.
