Example 2: a joint debugging method of a master station telecontrol information automatic joint debugging device comprises the following steps:

Automatic acceptance strategies: the automatic acceptance device simulates that spacer layer equipment triggers data change uploading according to a customized strategy, an information source is input data of network shutdown, and the information source triggers information source change according to the customized strategy. The automatic acceptance device generates data in batches based on the station control layer information interaction behavior of the SCD virtual simulation substation IED equipment according to the established generation strategies of real remote signaling, virtual remote signaling and telemetry signals, and performs functional tests such as receiving, processing and forwarding of the data communication gateway machine, so that automatic verification of monitoring information is realized. The customized strategies include a real remote signaling signal generation strategy, a communication interruption virtual remote signaling signal generation strategy and a telemetry signal generation strategy.

The telemechanical information source triggering strategy is to generate a unique identifiable source based on the RCD telemechanical point number, wherein the real telemechanical signal generating strategy library comprises the same signal value changing strategy and all signal value generating sequence strategies, and the time interval and the adjacent signal switching time interval; the communication interruption virtual remote signaling signal generation strategy library comprises a signal value change strategy, a time interval and an adjacent signal switching time interval; a telemetry signal generation policy repository contains signal value change policies, time intervals, and adjacent signal switching time intervals. These policy parameters may be configured to generate a custom policy for controlling the data source to send according to preset rules, as shown in fig. 1.

As shown in fig. 1, the interaction information triggering of the main station and the sub station is completed through 4 steps; the selected trigger strategy library realizes that the initial state of remote signaling is all divided, and the divided-combined-divided states are sequentially sent according to the point numbers; the initial state of the virtual remote signaling is that the communication is normal, and the communication links are sequentially disconnected according to the point numbers; and the telemetry initial value is 0, and the telemetry value is sent according to the point number plus the offset.

The data information SOE time mark uplink verification method comprises the following steps: in actual engineering of a transformer substation, the number of remote signaling information (state change of power equipment, such as switch from on to off) accounts for more than 80% of the total amount of the remote information, and the remote signaling information in the substation is recorded in a SOE (event sequence record) mode. When deflection occurs, the intelligent electronic equipment automatically records information such as deflection time, deflection behavior and the like to form SOE records.

The remote signaling information sheet generally contains the following information: information object (corresponding to some physical or logical object in the station), information behavior (occurrence or disappearance), information occurrence time (year-month-day-hour-minute-second-millisecond). Typically, the amount of information in a smart station is as much as tens of thousands, while the primary station service is not all that is required. The designer will select one or several information in the station, after one-to-one or many-to-one merging, form a regulation information point, and use the unique main station information object address (usually natural number) to mark, all regulation information points are integrated to form the regulation information table of the whole station. In short, the regulation information table prescribes information to be transmitted to the master station by the telemechanical device and corresponding numbers. The technician needs to complete the configuration of the telemechanical device to form the corresponding relation between the information index name in the station and the information object address of the master station. In operation, the telemechanical device receives and analyzes the action information in the station, generates the action information of the modulation master station once the information corresponds to the configured index name, and informs the action of the corresponding modulation information point of the master station by using a 104 protocol message, and meanwhile, the SOE time is attached.

The conventional tele-information checking mode is as follows: after the transformer substation and the master station staff are in place, the transformer substation staff generates a signal on site according to a regulation and control information table issued by the dispatching master station, the dispatching master station receives and displays action information which is transmitted by the telemechanical device and takes the number as the identification, the master station staff keeps talking with the staff in the transformer substation, the action signal point is judged by utilizing the change of 0 and 1 of the signal in specific time, and the description of the signal point is confirmed to correspond to the information generated by the transformer substation. Thus, checking of all information points is completed one by one. The conventional remote information checking method needs the cooperation of the substation end and the dispatching master station to check each regulation information one by one, and the two parties (the substation is simultaneously checked with a plurality of master stations and relates to a plurality of parties) need to be closely connected and cooperate. Because of huge (thousands of points) information quantity and a large number of dispatching master stations (ground dispatching, province dispatching, network dispatching and the like), the method causes heavy work load of field debugging, low work efficiency, usually takes days to complete the work, and the phenomenon that the work collides with other works or is developed in parallel often occurs. Because the status bits of the remote signaling information are only 0 and 1, when the remote information is checked, if other works generate actions and return actions of some remote signaling information in similar time, master station side check staff can be interfered, and erroneous judgment of action points can be caused.

The SOE time mark uplink data test technology is adopted to rapidly and accurately judge the correctness of the information point number conversion relationship in the telecontrol device. The main idea of the technology is to realize the self-description of the information object address by utilizing the information interaction process of the master station, break the real-time correlation of the work of the two ends of the master station and realize the rapid batch processing by means of an automation means. From the automatic information flow direction, the time stamp of the action signal is formed by the process layer or the spacer layer device according to the acquisition time in the signal acquisition link so as to reflect the signal generation time. The time information is identified and recorded in the telematic device and transmitted to the master station in the 104 th order (SOE mode) together with the associated signal point. The new method uses the thought of evidence theory by multiple attributes in error tolerance treatment to change the singleness of judgment quantity in work, artificially establishes the correlation among the attributes and is used for subsequent judgment, namely, the SOE time information bit is utilized to synchronously transmit the address of the control information point to which the SOE time information bit belongs to the master station, so as to help master station personnel judge whether the telemechanical device executes correct forwarding.

The implementation method of the SOE time mark uplink data test technology adopts simulation equipment (such as MMS communication simulation software and the like) to send out MMS communication messages of information actions in a certain station, and part of time data in SOE time marks in the messages are forced to be consistent with information addresses of regulation and control information points corresponding to the information. Specifically, the second data bit information describes ten-hundred-bit and kilobit of the information address, and the millisecond data bit describes ten-hundred-bit of the information address, so that the second and millisecond data bit information can correspond to 0-59999 information addresses. The year, month, day, time and position data of SOE time can be filled in or selected according to the actual specific numerical value. The transmission of SOE time values by the telemechanical device is a fixed behavior which is easy to verify and can not make mistakes in the whole process. Therefore, after the information received by the dispatching master station is correctly forwarded by the telemechanical device, the data corresponding to the second and millisecond bits of the SOE time of the information received by the dispatching master station is consistent with the information address of the master station, and if the data is inconsistent with the information address of the master station, the information is judged to be a conversion error of the telemechanical device.

In actual operation, the simulation equipment can sequentially send out all pieces of action information in the station to be checked according to the order of the 104 address numbers, and the master station side records all pieces of action information sent by the telemechanical device. This process takes only a few tenths of a minute, in a point of information every half second. And next, the master station personnel only need to observe that the SOE time data of the received action information is consistent with the information object address, and the quantity of the action information and the information object address distribution are consistent with the expected data, so as to judge whether the conversion of the telecontrol device is correct.

The SOE time mark uplink data testing method can quickly, conveniently and accurately check the correctness of the information conversion of the telecontrol device, and the main method flow is as follows:

(1) The simulation equipment sends out MMS communication message of information action in the station, and the time value in SOE time scale is consistent with the telemechanical information address corresponding to the information. The method combines the information in the transformer substation with the remote information address to which the information belongs, and enters the later information circulation.

(2) And the information in the batch of stations with the information address description of the master station is automatically sent out and is received by the dispatching master station after being forwarded by the telemechanical device. And judging whether the information conversion of the telecontrol device is correct or not by checking whether the SOE time value of the telecontrol information received by the main station is consistent with the address of the telecontrol device.

The simulation of the MMS protocol message sending behavior of the information acquisition device is a key technical means on which the SOE time mark uplink data testing technical method depends. The method is based on a set of software which can extract SCD file information and simulate a corresponding spacer layer device to realize specific content communication with a telemechanical device. For convenience of work, software should support a network card to simulate different addresses so as to correspond to a plurality of spacer layer devices. Because of the huge amount of information contained in SCD, software needs to take certain optimization measures when communication simulation is performed.

In the normal operating state, the SOE time is continued continuously. And the time of the subsequent event is earlier than the recorded event time in the telemechanical device when the SOE time is manually subjected to the dry prognosis. How the telematic device handles such situations is different from manufacturer to manufacturer. One possibility is to judge an event having a newly received SOE time earlier than the latest change time of the event in the telemechanical information base as abnormal information, and the transmission behavior of 104 is masked without performing subsequent processing on the signal change, so that verification cannot be performed. To avoid this, the SOE time of the signal generated by the simulation software should be extended backwards. In the checking work, in order to ensure that the initial state of the simulation software is consistent with the recording state of the telemechanical device, a round of switching operation can be carried out on all information points before formal recording.

When the information table is created, there are cases where a plurality of signals transmitted from the device correspond to one tele signal. Once the signal point corresponding error occurs, the main station side can find out but can not determine which signal is in error according to the corresponding relation between the information point number and the SOE time. For this, the sub sequence number information needs to be added to the SOE time. One simple approach is to further occupy the representation bits of "minutes" in SOE time. The first sub-signal is represented by XXX milliseconds for 00 minutes XX seconds, and the second sub-signal is represented by XXX milliseconds for 01 minutes XX seconds. Thus, the expression of 60 sub sequence numbers can be realized, and the general application can be satisfied. Finding out the information corresponding to each information point number in the regulation information table in the SCD file, and accurately marking the telemechanical information point number in the simulation software becomes a key for ensuring the correctness of the check work. This work needs to be done offline before testing. The staff confirms the information point by knowing the design content and according to the "description" or "dU" attribute description of each signal in the SCD file. Making statistics of the semaphore will help to improve the accuracy.

Although the application of the SOE time mark uplink data testing technology can take a certain time in the initial stage, the workload is definitely much smaller than that of the traditional manual setting, the working freedom degree is large, and the SOE time mark uplink data testing technology can be independently completed at any time and any place. If the method is carried out together with the work of compiling a regulation information table, the efficiency and the accuracy can be improved. The main advantages of this verification method are summarized below:

The data verification method of the transformer substation and the master station comprises the following steps: the data communication verification technology of the transformer substation and the master station mainly aims to ensure that information acquired by a dispatching end of the master station is consistent with information sent by the transformer substation. The data information verification method is generally based on a method for checking each information one by one in a power failure mode, and the correctness of the data in the processes of data acquisition, distribution, communication transmission, storage and display is completely verified. The traditional method can ensure the accuracy and the integrity of information verification, and the prior technical proposal does not realize complete replacement. With the development of the model information and communication configuration technology, the steady state transient state information simulation technology and the master station unified platform technology of the intelligent substation, the complete power failure information verification process can be verified in batches in a segmented mode, and according to different verification objects, stages and methods, a multi-angle, multi-state and different flow verification scheme is adopted to achieve the method for improving the data verification efficiency, so that the power failure time of on-site equipment is saved, and the on-site working efficiency is improved.

And the data verification process of the master station and the slave station comprises the following steps: the data verification process of the main station and the sub station is to complete the complete check from the primary equipment information to the main station information according to the power grid dispatching data requirement. The traditional transformer station technology is not clear enough in layering and grading, the data equipment model is not standardized enough, and usually only a power failure method can be adopted to complete the checking work of information. With the development of digital technology popularization and application, the data information model of the transformer substation enables a method of data information verification in steps to be possible without occurrence of bottom data signals through consistency description of SCD and CID files. The intelligent substation and intelligent scheduling system main substation data information verification system based on the intelligent power grid technology can be divided into the following six processes:

(1) Primary equipment signal acquisition, input and verification;

(2) Verifying process layer equipment data to spacer layer equipment data;

(3) Verifying the data of the spacer layer equipment to the data of the station control layer equipment (remote control network shutdown);

(4) The remote control network in the substation shuts down to schedule the data verification of the front-end communication system;

(5) The dispatch pre-system verifies the data information of the dispatch database,

(6) And scheduling verification of database data information to application interface graphical data information.

As shown in fig. 2, the six links must ensure complete correctness in the experimental verification process, so as to confirm that the verification of the data information from the substation equipment to the data information of the master station is completed. If the data information from the substation equipment information data to the main station is inconsistent, the reason of the inconsistent information needs to be checked step by step from bottom to top.

Firstly, starting from checking information in a transformer substation, confirming consistency of information of a primary equipment signal entering process layer equipment of the intelligent transformer substation and corresponding model data, and then checking that virtual terminals of the process layer equipment are connected to virtual terminals of spacer layer equipment to be connected correctly. The equipment aiming at the spacer layer needs to verify that the corresponding relation between the input information and the model is consistent, the spacer layer protects the information generated by the measurement control function to be accurate, and the data unified and standardized through the model information is accurately transmitted to the remote control network for shutdown through the station control layer network. The corresponding relation and the logical operation relation of the forwarding data table of the remote control network shutdown are correct, and the transmitted information corresponds to the information codes of the scheduling requirements one by one. The output data of the transformer substation can only be proved to meet the requirement of the scheduling information table through the process verification.

In addition, information verification aiming at a dispatching side is required to be carried out, dispatching demand information is sent to a dispatching communication data network through a remote gateway machine, data is successfully transferred to a front-end server of a dispatching master station through different dispatching communication logic planes, the front-end server accurately sends the data to a database system for updating and storing according to a mapping appointed relation of database table contents through a message bus, and application software of a front-end accurately displays the data information in the database to dispatching staff of the dispatching master station according to a correct graph data association relation through a callback function. After the verification of the process is completely correct, the consistency of the demand data of the master station system and the data sent out by the transformer substation can be ensured.

Master substation data authentication content: the primary and secondary station data verification process is commonly called primary and secondary station information 'point-to-point', and is an important measure for ensuring the safety of a power grid. The reconstruction and expansion intelligent substation is based on reconstruction and expansion of an original mature operation substation, original mature substation data information is subjected to a complete verification process, and data correctness based on original main substation data consistency verification is experimentally ensured. However, through implementation of reconstruction and expansion engineering, part of information in the original transformer substation is changed, so that following adjustment of a transformer substation description file SCD is caused, and a series of problems of changing an information point table of remote network shutdown, updating a data model at a master station end and the like are also involved. The main substation data information verification aiming at the transformer substation needs to systematically consider the balance between the actual power outage extension debugging condition of the transformer substation and the complete main substation data verification requirement. The inheritance of the data information which is verified originally is considered as much as possible, and the power failure period of the equipment is reduced on the basis of guaranteeing the data verification reliability.

Considering that the data information required by the master station is mainly based on complete description of SCD files of the transformer substation in the intelligent transformer substation, the secondary debugging process and the operation maintenance process of the whole transformer substation are required to be continuously perfected and updated with configuration information related to SCD, and the verification technology for the data information can adopt two modes of complete verification and incomplete verification.

(1) Transformer substation main station and sub station data information integrity verification

After the complete verification is based on the completion of debugging of the equipment in the reconstruction and expansion intelligent substation, the substation data information is completely verified through a method of total station power failure or a step-by-step and wheel-stop measure of the equipment.

All the equipment adopts a complete flow of data information verification of a main station and a sub station in a power failure mode, namely data verification is directly carried out from a primary equipment output signal end, after data signals are input and acquired and converted by a transformer substation process layer device merging unit and an intelligent terminal, the data signals are processed by a spacer layer protection measurement and control device to be sent to a station control layer for remote control and power off, and then a remote control gateway machine forwards an uplink dispatching end main station according to the dispatching information requirement, so that the information content verified by a dispatching personnel and a debugging maintenance personnel is required to be ensured to be accurately consistent with the information content actually transmitted by a transformer substation from the viewpoint of an application layer.

The data verification in the power failure mode does not need to consider the influence of data information errors in the signal verification process on the operation of substation equipment, and can perform complete and safe data information verification by generating signals through a data source end, and the content of the verification is mainly as follows:

1) And (3) remote signaling information verification: specific loops such as a switching circuit breaker, an isolating switch and the like simulate actual protection action signals; the contact information of the equipment is sent to the comprehensive measurement and control equipment through a GOOSE message, the remote control network is powered off through an MMS message, the IEC104 message is sent to the dispatching master station through a remote control gateway machine, and the consistency of the display content of the remote signaling information and the signal of the substation signal input end equipment is checked.

2) And (3) telemetry information verification: and the SV message output by the merging unit tester is sent to the measurement and control protection device to form an effective telemetry value to be sent to the sports network for shutdown, the SV message is sent to the dispatching master station through the IEC104 message, and the master station checks that the telemetry information display content value and the object are consistent with the substation input signal device.

3) And (3) remote control information verification: the master station side selects a control object through a remote control interface, completes remote control operation of a primary switch and a disconnecting link of the transformer station side through selection, confirmation and execution processes, and after the operation is completed, the master station side and a substation debugging personnel

And checking the consistency of the operation signals to finish the consistency of the signals of the remote control operation of the equipment.

4) Remote regulation information verification: the master station selects an adjusting object through a remote adjusting operation interface, and the adjusting operation of the remote adjusting object of the transformer substation is completed after the strategy selection, confirmation and execution of the adjusting control. And (5) carrying out verification of the regulation information through telemetry or remote signaling acquisition and return.

The data verified by the power failure mode complete data verification method is the most comprehensive, and relates to all data information verification of all links of primary terminal equipment of a transformer substation, including process layer equipment, spacer layer equipment, station control layer equipment, front-end master station, real-time master station database, SCADA of the master station and graphic information display of the master station, so that the method is the most comprehensive realization means for ensuring the complete and correct information, and the power failure of the whole transformer substation system is reduced to the minimum. For the transformer substation under reconstruction and expansion, complete experimental verification is carried out on the verification of the data information of the newly added reconstruction and expansion primary equipment and the verification of the data information of the original equipment before reconstruction and expansion engineering.

The data verification method in the power failure mode has the biggest defects that the method must be based on equipment power failure maintenance state, the process of data verification needs the mutual coordination of a master station and transformer substation personnel, the normal operation signal of the master station is easy to be interfered, the input information which is related to primary equipment and is required to be debugged for each scheduling requirement is huge in workload, and any link information is wrong, so that the problems faced in the error correction process are various, and the technology and the analysis level of related personnel are relatively high. In addition, the debugging is completed for too long, and the interference signal sent by the verification information is continuously existed for the dispatching staff in the debugging process.

(2) Incomplete verification of data information of main station and sub station of transformer substation

In the actual construction process of the transformer substation, the related intervals of reconstruction and expansion are required to be isolated for reconstruction and construction, and under the condition, other equipment and facilities in the transformer substation can still keep an operation state, and the normal and safe operation of other non-outage equipment is not influenced for the construction and debugging of reconstruction and expansion equipment. The extension interval can be combined with the associated interval information to complete the data information verification work without affecting other irrelevant running intervals.

Under the condition, the data verification of the main station and the sub station of the transformer substation needs to carry out a data verification method without directly changing signal information from the input end of the primary equipment signal, and the incomplete shape verification of the data information of the main station and the sub station of the transformer substation for reconstruction can verify the consistency of the data information of other uploading main stations of the transformer substation except for the interface information of the secondary equipment (namely, except for the signal verification below a process layer). Especially for the non-extension interval equipment information of the transformer substation, the consistency of the content of the data information uploading main station and the content originally uploaded can be ensured by an incomplete verification method. Based on the research on the flow of the data verification of the whole main station and the sub station, the data verification and debugging of the data in the process of the step 2-6 which is shown in the figure 2 and is irrelevant to the data collection of the primary equipment can be completed under the condition that the signal input of the primary equipment is not carried out in order to improve the efficiency of the data information verification, and the accuracy of the information is ensured only in the data collection stage of the primary equipment. In this case, when the primary device has the verification condition, the accuracy of data uploading can be ensured only by debugging and verifying the flow 1 in fig. 2, the workload of information verification can be greatly reduced, and the test method can also adopt an automatic data verification measure.

Aiming at the transformer substation, even if an incomplete data information verification method is adopted, the verification process of the data information is required to be completed by combining the power failure state of the primary equipment, the signal input verification process of the primary equipment is not reduced, the data verification efficiency can be greatly improved by verifying the steps 2-6 in the figure 2 through an automatic data verification method, the information verification and error correction can be completed as much as possible under the operation condition without involving the signal of the primary equipment, and the workload of complete data verification combined with the output signal of the primary equipment is greatly reduced.

Master substation data verification scheme: the data verification and verification method in the power failure mode is to complete one-time complete verification from primary equipment information to master station information, and the traditional transformer station technology is not standardized enough due to the fact that layering and grading are not clear enough, and the data equipment model can only be used for completing verification of information by adopting the power failure method. Based on advanced intelligent substation model data technology, the data information model of the substation enables a method of data information verification in steps to be possible through consistency description of SCD and CID files without occurrence of bottom data signals. The data information verification checking method based on the serialized data forwarding information is to verify the consistency of the data information sent by the substation side and the scheduling requirement information through the unified data description of the substation and the matching method of the description data information and the forwarding data information table of the remote control network. And then complete incomplete verification of the data of the main substation and the sub station in the running state.

The scheme adopts a simulated multifunctional measurement and control device, and relates to a regulation and control center master station, data information needing experimental verification in the master station, a preposed communication server, a data communication network, a transformer substation remote control network shutdown, a measurement and control device and the like, wherein the scheme realizes the following flow:

1. firstly, a serialized test data packet is constructed by combining a substation SCD file (substation total station system configuration file) containing complete information according to the content of a data information table of a scheduling requirement, the naming of the data information of the scheduling requirement is generally in strong association consistency with the naming of the SCD file, the character content of the data information of the scheduling requirement can be compared with the information description content in the SCD file by a fuzzy comparison method of character strings, and a substation data information sequence consistent with the data information table of the scheduling requirement can be constructed by matching the coupling degree of character string matching and matching with artificial identification. The arrangement mode of the substation data information sequences is consistent with the data content sequence of the dispatching requirement data information table.

2. And importing the constructed data information sequence into configured multifunctional measurement and control equipment capable of being transmitted according to continuous fixed time intervals, marking the data information of the scheduling requirement as a test message according to the agreed time sequence, and transmitting the test message to a remote control network through a station control layer network. The remote communication network is powered off and transmits information to a front-end server of a master station through a dispatching data communication network in an IEC104 protocol format based on a dispatching data demand information forwarding table. The front-end server analyzes the information content and sends the information content to the database, and the information content is displayed to the dispatching staff through the application graphical data interface. The information sent by the master station data verification information application module can be combined with the embedding of the test state information in the message, and is displayed to the tester through the interface of the master station debug state. For verification of data information at the master station end, the master station monitors and checks the deflection condition of personnel through a debugged interface to manually acquire the information.

3. The master station acquires data information of simulation forwarding of the transformer substation in a debugging state, distinguishes data information sent by a serialization simulation test of the transformer substation based on the debugging state, stores a record of a message sent by the simulation test based on application in the debugging state, and forms a simulation test record file.

4. The substation serialization simulation test data information record file and the scheduling requirement data information table file formed by the master station in the debugging state can be formed into an information record coupling degree report by adopting a character string matching identification method. The personnel participating in the test can judge the data consistency condition of test verification based on the information coupling condition.

After the data test verification is completed, the communication model, the communication loop, the database configuration and the investigation of the problems of the application association table can be carried out according to the verification result and aiming at the inconsistent result.

The test of the scheme applies the data sequence generation technology, completes the automatic processing of information transmission and reception, can utilize the matching recognition of the character strings to complete the preliminary verification of corresponding information data in the aspect of consistency comparison, and then is uniformly verified by test verifiers, thereby improving the verification efficiency and accuracy. A flow chart of an implementation of the scheme is shown in fig. 3.

Besides the method for automatically generating the data transmission sequence and semi-automatically checking the information point table, the data information verification checking scheme of the serialized data forwarding information can also adopt the following flexible mode in practical application:

(1) Selective verification method

Based on the structured serialized data information, a method of selecting and transmitting and checking one by one can be performed, and the information content of a transmitting scheduling end needing a simulation test is manually selected by manually selecting the scheduling information demand table and the corresponding data information content of the SCD file, and the generation and the checking of piece by piece of simulation data are performed. According to the content of the dispatching data information table, each piece of dispatching information corresponds to one data point, the information content of the data point corresponding to the SCD file is sent to the master station debugging state database, and if the information is consistent with the information of the dispatching requirement, the correctness of the verification of the piece of information is proved.

The manual piece-by-piece data information verification method can be used as a supplement to an automatic sequence verification method, can also be used as a means of error correction and debugging tests after the error occurs in the information data content at a certain point, gradually traces back the content error reasons of a single data information message, and flexibly eliminates the fault reasons of inconsistent data information verification.

(2) Incremental information checking method

The incremental information sending verification and verification method is mainly used for data debugging and verification of the transformer substation, and because the information of the reconstruction and expansion interval and the information of the reconstruction and expansion association interval change, the information verification is needed, the information content associated with the reconstruction and expansion can be acquired based on the complete scheduling requirement information table content, the data information table to be tested is rearranged, and the newly added data information content of the transformer substation can be verified only by sending the added information content of the transformer substation to the running environment in the debugging state of the scheduling master station. The incremental data information checking method can adopt an automatic sending and piece-by-piece checking method, can be more focused on data information verification and debugging of incremental demand information of the transformer substation, better inherits verified data information, and reduces workload.

The foregoing is merely illustrative of the present invention, and the scope of the present invention is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the scope of the present invention, and therefore, the scope of the present invention shall be defined by the scope of the appended claims.
