[0002] With the continuous development of the power system, there are more and more power data in the power system, and these power data are important data for analyzing the state of the power grid system, which has an important influence on the normal operation and maintenance of the power grid system.

[0003] At present, the collection method of power data mainly uses the collection unit on the side of the electric meter box to collect the real-time electrical quantity of the corresponding electric meter, and obtains the electrical data such as the voltage, current and power of the electric meter. However, this collection method can collect the electrical data corresponding to each electric meter, but since the collection units corresponding to each electric meter work independently, it is easy to cause the collected data to be out of synchronization at some collection time, affecting the data quality, and only collecting the electric meter power data makes the collected data single, which is difficult to meet the demand of power system state analysis. SUMMARY

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0027] Example 1

[0028] Figure 1 This is a flowchart of a data processing method provided in Embodiment 1 of the present invention. This embodiment is applicable to data acquisition. The method can be executed by the data processing device in this embodiment, which can be implemented in software and / or hardware, optionally through an electronic device, such as a mobile terminal, PC, or server. The device can be configured in a computing device. The data processing method provided in this embodiment specifically includes the following steps:

[0029] S110. Obtain the first electrical information corresponding to the master table within a preset time period, and send a data acquisition request to at least one device to be acquired, so as to calibrate the acquisition time corresponding to each device to be acquired based on the data acquisition request, and to enable each device to acquire the second electrical information corresponding to each monitoring device based on the data acquisition request and calibration result.

[0030] The master meter refers to the device used to statistically analyze the power information corresponding to all sub-meters. The first electrical information may include, but is not limited to, data such as voltage, current, active power, reactive power, harmonics, frozen power, and events. The data acquisition device is used to collect the electrical information corresponding to the monitoring device. Optionally, the data acquisition device can be a broadband carrier STA (Station). The data acquisition request may include time synchronization data and acquisition task data. For example, the acquisition task data may be to collect electrical quantities once per minute, including voltage, current, active power, reactive power, harmonics, and frozen power. Each data acquisition device corresponds to one monitoring device. Optionally, the data acquisition device can communicate with the monitoring device via a 485 line. The monitoring device includes smart switches and sub-meters. A smart switch is a switch used to control the operation of several sub-meters. For example, in an electrical quantity monitoring scenario, the electricity meter can be used as a sub-meter, and the lines corresponding to each sub-meter will be connected to the distribution room. The master meter in the distribution room will then perform the total electrical quantity statistics. (See [link to relevant documentation]). Figure 2This can be represented as a structural diagram of a master table, smart switches, and sub-tables. The preset duration includes at least one preset sub-duration; for example, the preset duration can be 15 minutes, and the preset sub-duration can be 1 minute.

[0031] In this embodiment, when the high-voltage electricity corresponding to each sub-meter is received, it can be considered that the total electrical information, i.e., the first electrical information, has been received. For example, in practical applications, when the 10kV high-voltage power lines corresponding to each sub-meter are connected to the distribution room, they will be transformed by a transformer to a 380V three-phase power supply, such as phase A, phase B, and phase C. The three phases can communicate with the TTU (distribution transformer supervisory terminal unit) in the main meter. The TTU can detect electrical information such as the total current, total voltage, and total power output of the three phases, and this electrical information can be used as the first electrical information. Optionally, this electrical information can also be stored in an archive log at the minute level, for example, several 1-minute intervals of electrical information can be stored in the archive log. This allows the first electrical information within a preset time period to be retrieved from the archive log; it also allows the first electrical information within a preset time period to be obtained in real time when the TTU detects several 1-minute intervals of total electrical information.

[0032] Building upon the aforementioned scheme, communication between the TTU and each target device (STA) can be established using carrier cables. The TTU can send data acquisition requests to each STA, allowing each STA to calibrate its acquisition time based on the time synchronization data within the request. Furthermore, it can execute the data acquisition request based on the calibration result. By parsing the data acquisition request, the acquisition task carried on it can be obtained. Each STA will acquire electrical information from the corresponding monitoring equipment, i.e., the second electrical information. This technical solution, by calibrating the time of each STA, ensures that the acquired first electrical information and the second electrical information are on the same time plane, improving the accuracy of data transmission and the quality of data acquisition.

[0033] It should be noted that in actual three-phase circuits, to protect the stability and safety of the line, a neutral wire can be drawn from the three-phase circuit. The neutral wire is the fourth wire in a three-phase four-wire system, and it is drawn from the neutral point of the three-phase power. Therefore, to improve the accuracy of the first electrical information acquisition, when communicating between the three-phase lines and the TTU, and detecting the total output current, total voltage, and total power of the three phases through the TTU, the current, voltage, or power output by phases A, B, C, and the neutral wire can be processed. For example, the currents output by phases A, B, C, and the neutral wire can be added together to obtain the total current information, which can be used as one of the electrical information items in the first electrical information. It should also be noted that when the high-voltage electricity from the sub-meters is introduced into the power distribution room, a transformer is used to step down the high-voltage electricity to improve safety. Therefore, the total current information obtained by the summation process is the power information after the voltage transformation, which is insufficient to represent the original output current information of each sub-meter in the power distribution room. The total current information can be boosted to obtain the boosted total current information, so that it can represent the original output total current information of each sub-meter and improve the accuracy of data acquisition.

[0034] Optionally, obtaining the first electrical information corresponding to the master meter within a preset time period includes: obtaining the three-phase electrical information and neutral electrical information corresponding to the master meter within a preset time period; merging the three-phase electrical information and the neutral electrical information to obtain the electrical information to be matched; and performing proportional processing on the electrical information to be matched to obtain the first electrical information corresponding to the master meter.

[0035] The three-phase electrical information may include the electrical information of phase A, phase B, and phase C.

[0036] In practical applications, a TTU can be used to collect the electrical information of phase A, phase B, phase C, and neutral wire corresponding to the main meter within a preset sub-duration. This information can then be merged to obtain the merged electrical information, i.e., the electrical information to be matched. For example, the electrical information corresponding to at least one indicator item (voltage, current, power, harmonics) of each of the four phases can be merged. For instance, the output voltages corresponding to phases A, B, C, and neutral wire can be merged to obtain the total voltage information, and the output currents corresponding to phases A, B, C, and neutral wire can be merged to obtain the total current information. Correspondingly, the total electrical information corresponding to each indicator item can be obtained as the electrical information to be matched. At this point, the electrical information to be matched is the electrical information of each sub-meter's high-voltage power after being processed by a transformer. The electrical information to be matched can be proportionally processed; for example, it can be transformed based on the distribution ratio to obtain the first electrical information that can characterize the total electrical information output by each sub-meter, i.e., the first electrical information corresponding to the main meter.

[0037] It should be noted that, in order to reduce the system's operational pressure and improve the convenience of data acquisition, an intermediate transmission device can be set up between the system and each device to be acquired. This allows the system to transmit instructions or requests to each device through the intermediate transmission device, and also allows the intermediate transmission device to store minute-level electrical information stored in each device to be acquired, so that the system can directly obtain the second electrical information from the intermediate transmission device.

[0038] Optionally, sending a data acquisition request to at least one device to be acquired includes: sending a data acquisition request to an intermediate coordinating device to enable the intermediate coordinating device to calibrate the coordination time based on the data acquisition request, and enabling the intermediate coordinating device to send the data acquisition request to at least one device to be acquired based on the calibration result.

[0039] The intermediate coordinating device can be a CCO (Central Coordinator). Data acquisition requests may include, but are not limited to, time synchronization information, acquisition period, and at least one acquisition item. The acquisition period can be 1 minute, and acquisition items may include, but are not limited to, voltage, current, active power, reactive power, harmonics, frozen power, and events.

[0040] In practical applications, the TTU can send data acquisition requests to the intermediate coordinating device (CCO). When the CCO receives the data acquisition request, it can perform time synchronization based on the time synchronization data carried in the request. It can also send the data acquisition request to each target device (STA) based on the accurate time synchronization result, enabling each STA to perform time synchronization and obtain the corresponding second electrical information based on the data acquisition request and calibration results. For example, the TTU can send the time synchronization time to the CCO in the concentrator via the RTU (Remote Terminal Unit). The CCO synchronizes its own clock based on the time synchronization time and then synchronizes the time synchronization time to each target device (STA) module, thus synchronizing the time of each STA module. The TTU can also send the acquisition cycle and at least one acquisition item to the CCO in the concentrator via the RTU, such as: acquiring electrical quantities once per minute, and specifying which electrical quantities to acquire. The CCO then sends the acquisition cycle and at least one acquisition item to each STA module. The STA can collect the corresponding minute-level electrical information of the monitoring device based on the data sent by the CCO. It can also store the electrical information collected every minute in the local STA, storing it as a group of electrical information per minute. Accordingly, it can store several groups of electrical information corresponding to one minute.

[0041] It should be noted that after the data acquisition request is sent to each device to be acquired, each device can synchronize its time based on the time information carried in the data acquisition request. It can also collect electrical information from the corresponding monitoring device based on the acquisition period and acquisition items carried in the data acquisition request, thereby obtaining the second electrical information corresponding to each monitoring device. In order to ensure the accuracy of the second electrical information obtained by the system, the minute-level electrical information collected by the STA can be pre-stored in the STA. The stored electrical information can also be reported to the intermediate coordination device CCO on time so that the system can directly obtain the second electrical information from the CCO.

[0042] Optionally, each device to be acquired obtains the second electrical information corresponding to each monitoring device based on the data acquisition request and calibration results, including: for each device to be acquired, parsing the data acquisition request based on the current device to be acquired to obtain the acquisition period and each acquisition item carried in the data acquisition request, and based on the calibration results, obtaining the data of each acquisition item in at least one acquisition period in the monitoring device corresponding to the current device to be acquired; based on the data of each acquisition item, determining the second electrical information corresponding to the monitoring device, and storing the second electrical information in the current device to be acquired, so that the intermediate coordination device can retrieve the second electrical information from the current device to be acquired.

[0043] Specifically, when each device to be collected collects the second electrical information of the corresponding monitoring device, the second electrical information collected by any device to be collected can be processed as the second electrical information collected by the current device to be collected, so as to describe one of the devices to be collected as the current device to be collected.

[0044] In practical applications, when the device to be acquired receives a data acquisition request, it can parse the request to obtain the acquisition period and each acquisition item carried in the request. For example, it might acquire electrical information once per minute, collecting data on voltage, current, active power, reactive power, harmonics, frozen power, and events. Furthermore, based on calibration results, the device to be acquired can acquire data on each acquisition item within at least one acquisition period from the corresponding monitoring device. For instance, if device STA1 corresponds to smart switch 1, STA1 can be used to acquire the electrical data corresponding to smart switch 1. For example, it can acquire the electrical data corresponding to each acquisition item once per minute, resulting in several one-minute electrical data sets, which include the data for each acquisition item. Electrical data corresponding to each cycle can be stored in STA1 so that intermediate coordination devices can retrieve electrical information from STA1. Alternatively, STA1 can report electrical information of each smart switch and sub-meter to the intermediate coordination device on time. For example, STA1 can package N minutes of collected electrical information into a single data packet and report it to the concentrator CCO module according to the query task. The CCO module then sends it to the RTU, and the RTU forwards it to the system TTU so that the system can receive the second electrical information fed back by each device to be collected.

[0045] S120. Receive the second electrical information fed back by each device to be collected within the preset time period, and perform queue processing on the first electrical information and each second electrical information to obtain the electrical data to be processed corresponding to each preset sub-time period.

[0046] In this embodiment, after each device to be collected reports minute-level electrical information to the concentrator CCO module, a data read signal can be sent to the CCO module. For example, if the preset duration is configured as 15 minutes, the data read signal can read the second electrical information within 15 minutes. This allows the CCO module to receive the data read signal and report the minute-level electrical information within 15 minutes corresponding to each smart switch and sub-meter to the system as the second electrical information. Each second electrical information contains 15 electrical information records of 1 minute each. When the feedback of each second electrical information is received, the second electrical information and the first electrical information can be queued and sorted. For example, if the electrical data corresponding to each minute in each second electrical information and the first electrical information is treated as a record, 15 records can be obtained. Each record includes the data of each collected item corresponding to each second electrical information and the first electrical information within one minute. Each record can be used as the electrical data to be processed corresponding to a preset sub-duration.

[0047] It should be noted that, in order to improve the accuracy of data collection and prevent missed collection or reading, when processing the first electrical information and each second electrical information in a queue to obtain the electrical data to be processed corresponding to each preset sub-time period, the first electrical information and each second electrical information within each preset sub-time period can be integrated and processed based on the order corresponding to each preset sub-time period to obtain the electrical data to be processed corresponding to each preset sub-time period.

[0048] Optionally, the first electrical information and each of the second electrical information are queued to obtain the electrical data to be processed corresponding to each preset sub-duration, including: for each preset sub-duration, retrieving the electrical data to be integrated corresponding to the current preset sub-duration from the first electrical information and each of the second electrical information; and queuing the electrical data to be integrated based on the arrangement order of each preset sub-duration to obtain the electrical data to be processed corresponding to each preset sub-duration.

[0049] In this embodiment, data from each collected item within the first electrical information and each second electrical information within the current preset sub-time period can be retrieved as the electrical data to be integrated. Then, based on the arrangement order of each preset sub-time period, each piece of electrical data to be integrated is queued, resulting in the electrical data to be processed for each preset sub-time period. For example, the minute-level electrical information within a preset time period of 15 minutes corresponding to the master table, each smart switch, and the sub-table can be used as a queue module. This queue module contains 15 queue units, arranged chronologically. Each queue unit contains data from each collected item within a preset sub-time period of 1 minute, corresponding to the master table, each smart switch, and the sub-table. Furthermore, the collected data within each minute are located on the same time plane, ensuring that the electrical information of the master table, each smart switch, and the sub-table is collected simultaneously every minute, and that the electrical information within each minute is on the same time plane. This greatly ensures the accuracy of data collection and reduces errors. It also improves data richness and data collection quality.

[0050] S130. If it is detected that each preset sub-duration is continuous, then based on each electrical data to be processed, the target electrical data is determined, and fault detection is performed based on the target electrical data.

[0051] In this embodiment, after obtaining the electrical data to be processed corresponding to each preset sub-duration, the electrical data to be processed corresponding to each preset sub-duration can be detected. If each preset sub-duration contains electrical data to be processed, then each preset sub-duration can be considered continuous. At this time, each electrical data to be processed can be used as target electrical data for subsequent fault detection based on the target electrical data.

[0052] It should be noted that when the continuity of each preset sub-duration is detected, and the target electrical data is determined based on each piece of electrical data to be processed, it is possible to check whether there is corresponding electrical data to be processed for each preset sub-duration. If so, it indicates that the electrical data to be processed corresponding to the preset sub-duration is complete. Alternatively, if the electrical data to be processed corresponding to the preset sub-duration contains data from each acquisition item, it can be considered that the electrical data to be processed corresponding to the preset sub-duration is complete. If each piece of electrical data to be processed is complete, the preset sub-durations can be considered continuous, and the target electrical data can then be determined based on each piece of electrical data to be processed.

[0053] Optionally, if the preset sub-durations are detected to be continuous, the target electrical data is determined based on each electrical data to be processed, including: determining the inspection result corresponding to each electrical data to be processed; if each inspection result is data integrity, then each preset sub-duration is continuous; and integrating the electrical data to be processed to obtain the target electrical data.

[0054] The test results include data missing and data completeness.

[0055] In this embodiment, the data of each collected item corresponding to the master table, each smart switch, and each sub-table in the electrical data to be processed can be detected. If the data is complete and without missing data, the detection result can be considered that the data is complete. If all detection results are complete, the preset sub-time periods can be considered to be continuous. The electrical data to be processed can be integrated to obtain the target electrical data. For example, in practical applications, it can be determined whether the electrical data within each preset sub-time period of the preset time period has been read. If all data has been read, the electrical data read within the current preset time period can be used as the target electrical data. Furthermore, the target electrical data within the next preset time period can be obtained.

[0056] It should be noted that after determining the inspection results corresponding to each piece of electrical data to be processed, if there is data missing in each inspection result, it indicates that there may be a situation where electrical data within a certain preset sub-time period is missed in the electrical data read this time. In order to improve the accuracy of data acquisition and ensure the accuracy of subsequent fault detection, when the inspection result is detected as data missing, the electrical data corresponding to the preset sub-time period corresponding to the inspection result can be reread, and the inspection result corresponding to the electrical data can be re-determined until the inspection result is complete.

[0057] Based on the above scheme, optionally, the method further includes: if the test result is that the data is missing, then based on the preset sub-duration corresponding to the electrical data to be processed, obtain the electrical data to be processed corresponding to the preset sub-duration from the first electrical information and each of the second electrical information, and determine the test result corresponding to the electrical data to be processed.

[0058] Specifically, when a test result indicating missing data is detected for the electrical data to be processed, a preset sub-duration period corresponding to that test result can be determined. Then, the electrical data corresponding to the preset sub-duration period in the CCO can be reread, or the electrical data within the preset sub-duration period received by the system TTU can be reread to ensure that each preset sub-duration period contains data from the master meter, each smart switch, and each data item corresponding to the sub-meters. The data integrity of the reread electrical data corresponding to that preset sub-duration period can be re-checked to obtain a test result, until the test result indicates data integrity, at which point the current round of preset-duration data acquisition ends.

[0059] The technical solution of this embodiment obtains the first electrical information corresponding to the main meter within a preset time period and sends a data acquisition request to at least one device to be acquired. This allows for calibration of the acquisition time corresponding to each device based on the data acquisition request. Based on the data acquisition request and calibration results, the second electrical information corresponding to each monitoring device is obtained. The second electrical information is then received, and the first electrical information and each second electrical information are queued to obtain the electrical data to be processed corresponding to each preset sub-time period. If the preset sub-time periods are detected to be continuous, the target electrical data is determined based on each electrical data to be processed. This solves the problem in the prior art where the power data of the meter is acquired based on the acquisition unit, resulting in asynchronous data acquisition in time. This resulted in poor data quality and limited data types. To address this, a calibration system was implemented based on the acquisition time of each device to be acquired. This ensures that the first power information in the master table, the second power information corresponding to each smart switch, and the second power information corresponding to each sub-table are synchronized across minute-level timeframes. This improves the richness of the acquired data while guaranteeing synchronization of power information within each preset sub-time period, reducing time errors in the acquired data. Furthermore, the continuity of each preset sub-time period is detected. If the preset sub-time periods are continuous, the target power data is determined to ensure that power data exists every minute, reducing missed acquisitions and readings, and ultimately improving the technical effect of data acquisition quality.

[0060] Example 2

[0061] As an optional embodiment of the above embodiments, in order to enable those skilled in the art to further understand the technical solution of the embodiments of the present invention, specific application scenario examples are given. For details, please refer to the following specific content.

[0062] For example, in a power distribution network electrical data acquisition scenario, the communication modules of each sub-meter can be pre-configured with the devices to be acquired, each smart switch can be pre-configured with the devices to be acquired, and an intermediate coordination device can be configured in the concentrator. The devices to be acquired can be broadband carrier STA modules, and the intermediate coordination device can be a CCO module. Each sub-meter communicates with its corresponding STA using a 485 line, each smart switch communicates with its corresponding STA using a 485 line, each STA communicates with the CCO using a carrier wave, and the CCO communicates with the RTU using a carrier wave. A broadband carrier network can be formed by the RTU, CCO, and each STA in the TTU, see [reference needed]. Figure 3 .

[0063] Based on the above scheme, see, for example, [example not provided]. Figure 4Based on the existing data collection network, the addresses of each smart switch can be added to the intermediate coordinating device (CCO) to integrate the smart switches into the carrier-based data collection network. Since the electricity meters are within the meter collection scope, they do not need to be added and can automatically participate in the CCO network. The RTU in the TTU can send the CCO address to the meter reading concentrator. The CCO then sends the CCO address to the STA (Stationary Data Acquisition Device) corresponding to each smart switch and the STA corresponding to each sub-meter. All STAs use the CCO address as their target storage address, and all data collected by each STA can be sent to this target storage address via carrier wave. The TTU can also be configured with broadcast cycles, time synchronization information, and data acquisition tasks for each STA. For example, the TTU synchronizes the time with the CCO via the RTU, and the CCO then broadcasts the time synchronization to each STA. The TTU can synchronize the time with the CCO once a day to ensure that the time on all STAs is consistent with the TTU's time, so that the first electrical information corresponding to the master meter and the first electrical information corresponding to each smart switch and each sub-meter are on the same time plane. The TTU sets the STA broadcast cycle for the CCO via the RTU, so that the CCO will periodically broadcast time synchronization and data acquisition tasks to the smart switch data acquisition STAs and the sub-meter data acquisition STAs. The RTU in the TTU can send data acquisition requests to the CCO. The data acquisition request includes the broadcast cycle, time synchronization information, and data acquisition tasks for each STA. The data acquisition task can include the acquisition items, i.e., the indicators acquired by the STA, and the acquisition cycle, such as a minimum cycle of once per minute. The acquisition items can include, but are not limited to, voltage, current, power, harmonics, frozen power, and at least one of the following events. After receiving a data request, each STA can collect minute-level data according to the collection task issued by the CCO. For example, each STA can collect electrical information once per minute according to the collection task. The STA can also store the electrical information collected every minute in its local storage, storing electrical quantities in groups of one minute. Each STA can report the locally stored minute-level electrical information to the CCO on a regular basis, such as once a day. The CCO can store the received minute-level electrical information in the network profile. It can also obtain the address and phase of each STA from the CCO network profile and create a read task for each STA in the TTU. The read task is at the minute level. For example, if it is necessary to obtain N minutes of data from one minute to the next, the STA module can package the N minute-level collected data into a single data packet and report it to the concentrator CCO according to the read task. The CCO then sends it to the RTU, and the RTU forwards it to the TTU.For example, a reading task might involve reading electrical data within a preset 20-minute timeframe, minute by minute. The TTU, based on this minute-by-minute reading task, uses the CCO to read the electrical data already collected by each STA at the minute level and feeds the data back to the TTU. Simultaneously, it determines whether the electrical data for the current preset timeframe has been read. If so, it continues reading the electrical data already collected by each STA at the minute level via the CCO to obtain the electrical data for the next preset timeframe. If not, it retrieves the addresses and phases of each STA from the CCO network profile and reads the power data according to the reading task established for each STA in the TTU. This ensures that the electrical quantities of switches and meters are collected simultaneously every minute, and that the data for each minute is on the same plane, greatly guaranteeing the accuracy of data acquisition and reducing errors. The TTU can also be used to collect minute-level first electrical information within a preset time period corresponding to the master meter. Accordingly, based on the first electrical information and each second electrical information, the power data to be processed corresponding to each preset sub-time period can be obtained. The integrity of each power data to be processed can be checked. If the detection result of the power data to be processed is that the data is missing, the power data corresponding to the preset sub-time period corresponding to the power data to be processed is reread until there is data for every minute. It can be considered that each preset sub-time period is continuous. At this time, the power data corresponding to each preset sub-time period can be used as the target power data for fault detection, such as line loss detection.

[0064] The technical solution of this embodiment obtains the first electrical information corresponding to the main meter within a preset time period and sends a data acquisition request to at least one device to be acquired. This allows for calibration of the acquisition time corresponding to each device based on the data acquisition request. Based on the data acquisition request and calibration results, the second electrical information corresponding to each monitoring device is obtained. The second electrical information is then received, and the first electrical information and each second electrical information are queued to obtain the electrical data to be processed corresponding to each preset sub-time period. If the preset sub-time periods are detected to be continuous, the target electrical data is determined based on each electrical data to be processed. This solves the problem in the prior art where the power data of the meter is acquired based on the acquisition unit, resulting in asynchronous data acquisition in time. This resulted in poor data quality and limited data types. To address this, a calibration system was implemented based on the acquisition time of each device to be acquired. This ensures that the first power information in the master table, the second power information corresponding to each smart switch, and the second power information corresponding to each sub-table are synchronized across minute-level timeframes. This improves the richness of the acquired data while guaranteeing synchronization of power information within each preset sub-time period, reducing time errors in the acquired data. Furthermore, the continuity of each preset sub-time period is detected. If the preset sub-time periods are continuous, the target power data is determined to ensure that power data exists every minute, reducing missed acquisitions and readings, and ultimately improving the technical effect of data acquisition quality.
