Description

Technical Field

[0001] The present invention relates to the technical field of anti-error information access for remote operation of power grid control, and in particular to an automatic acceptance method and system for anti-error information access for power grid. Background Art

[0002] In order to ensure the safety of remote operation of power grid control, the existing technology needs to develop corresponding remote operation safety and error prevention technology on the power grid dispatching and control system (hereinafter referred to as the control system). A remote operation safety and error prevention technology based on the substation microcomputer error prevention system, by formulating the master-substation error prevention information communication specification, connects the substation error prevention information and the error prevention logic rules in the microcomputer error prevention system to the control system, and realizes the error prevention verification of remote operation. In order to ensure the reliability of the remote operation safety verification, it is necessary to inspect and accept the substation error prevention information connected to the control system.

[0003] The existing automatic verification technologies for master-substation interaction information applied to monitoring information acceptance are divided into two categories: one is mainly through the construction of an intelligent substation monitoring information automatic acceptance system, adding an automatic acceptance device on the substation side, and adding an automatic acceptance function module on the control master station side. The automatic acceptance device on the substation side has the functions of telecontrol configuration information verification, synchronous acceptance of telecontrol information and monitoring background information. The automatic acceptance function module on the control master station side has the functions of pre-configuration information verification, automatic verification of monitoring information, etc.; the other type of master-substation interaction information automatic verification is completed by the substation automatic acceptance device and the master station automatic acceptance function module. The automatic acceptance device simulates the IEC61850 MMS server-side information interaction behavior trigger information of the substation protection and measurement and control device, and adds a 104-channel between the automatic acceptance device and the control master station to realize the master-substation interaction in the automatic verification process.

[0004] However, the existing automatic acceptance technology for monitoring information must rely on the automatic acceptance device at the substation end. There is no sound master-substation coordination mechanism. It is difficult to ensure the consistency of verification strategies between master and substations, and the acceptance process is prone to disorder, resulting in low fault tolerance and anti-interference ability of information acceptance. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a method and system for automatic acceptance of power grid information access without setting up a dedicated automatic acceptance device in the substation, so that the control master station and the substation can fully coordinate and interact, thereby improving the fault tolerance and anti-interference of information acceptance.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A method for automatic acceptance of power grid error-proof information access, comprising the steps of:

[0008] S1. Set the anti-error information access acceptance task according to the acceptance equipment object, acceptance task type and acceptance task status;

[0009] S2, setting a first-level acceptance task including acceptance equipment object information and acceptance task type information, setting a second-level acceptance task including acceptance equipment object information, acceptance task type information and acceptance task status information, and combining a preset number of the second-level acceptance tasks with the same acceptance equipment object and acceptance task type into a first-level acceptance task;

[0010] S3, sorting the two or more first-level acceptance tasks to obtain a task sequence;

[0011] S4. Taking out the first-level acceptance tasks one by one in the order of the task sequence, and automatically verifying the interactive information with the substation microcomputer error prevention system based on the first-level acceptance tasks.

[0012] In order to solve the above technical problems, another technical solution adopted by the present invention is:

[0013] A power grid error-proof information access automatic acceptance system, comprising a master station error-proof information acceptance function module arranged at a control master station;

[0014] The master station error-proof information acceptance function module is used to execute the above-mentioned power grid error-proof information access automatic acceptance method.

[0015] The beneficial effects of the present invention are: providing a method and system for automatic acceptance of power grid anti-error information access, defining anti-error information access acceptance tasks according to information such as acceptance equipment objects and acceptance task types, and grading and sorting the anti-error information access acceptance tasks, and then automatically verifying the interactive information, without the need to set up a dedicated automatic acceptance device in the substation; solving the problem of consistency of verification strategies between the control master station and the substation through task-based settings, and making the acceptance process of the control master station less prone to disorder through serialization processing, making up for the defect of insufficient coordination and interaction between the control master station and the substation, and improving the fault tolerance and anti-interference of anti-error information access acceptance.

[0024] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0025] Please refer to Figure 1 , Figure 3 as well as Figure 5 , a method for automatic acceptance of power grid error-proof information access, comprising the steps of:

[0026] S1. Set the anti-error information access acceptance task according to the acceptance equipment object, acceptance task type and acceptance task status;

[0027] S2, setting a first-level acceptance task including acceptance equipment object information and acceptance task type information, setting a second-level acceptance task including acceptance equipment object information, acceptance task type information and acceptance task status information, and combining a preset number of the second-level acceptance tasks with the same acceptance equipment object and acceptance task type into a first-level acceptance task;

[0028] S3, sorting the two or more first-level acceptance tasks to obtain a task sequence;

[0029] S4. Taking out the first-level acceptance tasks one by one in the order of the task sequence, and automatically verifying the interactive information with the substation microcomputer error prevention system based on the first-level acceptance tasks.

[0030] From the above description, it can be seen that the beneficial effects of the present invention are: defining the anti-error information access acceptance task according to the acceptance equipment object, acceptance task type and other information, and grading and sorting the anti-error information access acceptance task, and then automatically verifying the interactive information, without the need to set up a dedicated automatic acceptance device in the substation; solving the verification strategy consistency problem of the control master station and the substation through task setting, and making the acceptance process of the control master station less prone to disorder through serialization processing, which makes up for the lack of coordination and interaction between the control master station and the substation, and improves the fault tolerance and anti-interference of the anti-error information access acceptance.

[0031] Furthermore, the automatic verification of the interactive information includes:

[0032] Sending a first-level task selection request to the substation microcomputer error prevention system, the substation microcomputer error prevention system performs information verification and initialization operations on the first-level acceptance task corresponding to the first-level task selection request and returns a first-level task response;

[0033] When the primary task response is passed, a secondary task execution request is sent to the substation microcomputer error prevention system, and the substation microcomputer error prevention system verifies the information of the secondary acceptance task corresponding to the secondary task execution request and returns a secondary task response;

[0034] The secondary acceptance task is executed when the secondary task response is passed.

[0035] From the above description, it can be seen that when performing automatic verification of interactive information, verification is strictly carried out according to the order of the task sequence and the level division of the acceptance task. Only after the first-level task selection request is correctly responded to, the second-level task execution request and the execution of the second-level acceptance task are continued, thereby effectively preventing the acceptance process disorder and safety risks caused by abnormal acceptance instructions of the control master station, so that the entire acceptance process can be carried out in a standardized manner.

[0036] Furthermore, the automatic verification of the interactive information further includes:

[0037] A first-level task termination request is sent to the substation microcomputer error prevention system, and the substation microcomputer error prevention system performs information verification and reset operations on the first-level acceptance task corresponding to the first-level task termination request and returns a reset response.

[0038] From the above description, it can be seen that the automatic verification of interactive information also includes the first-level task termination request and response. Information verification can effectively prevent termination failures caused by problems such as task information mismatch. When multiple first-level acceptance tasks need to be executed, it is ensured that the first-level acceptance task can be successfully terminated after executing all the second-level acceptance tasks it contains, so as to facilitate the next first-level acceptance task.

[0039] Furthermore, while sending the first-level task selection request to the substation microcomputer error prevention system, timing is performed and determining whether the first-level task response is received;

[0040] If the first-level task response is not received and the timing duration exceeds the first preset waiting duration, resending the first-level task selection request;

[0041] Sending the secondary task execution request to the substation microcomputer error prevention system while timing and determining whether the secondary task response is received;

[0042] If the secondary task response is not received and the timing duration exceeds the second preset waiting duration, the secondary task execution request is resent.

[0043] From the above description, it can be seen that when the first-level task selection request and the second-level task execution request are issued, the first preset waiting time and the second preset waiting time are set respectively to form a timeout processing mechanism, so that the request can be resent when the substation microcomputer error prevention system does not respond, which helps to determine whether an abnormality has occurred in the substation and reliably terminate the automatic acceptance process of the error prevention information after the abnormality occurs.

[0044] Furthermore, while sending the secondary task execution request to the substation microcomputer error prevention system, the second preset waiting time is set according to the acceptance task status of the secondary acceptance task corresponding to the secondary task execution request.

[0045] From the above description, it can be seen that the second preset waiting time is set according to the acceptance task status, so that the time setting of the timeout waiting is more flexible, has higher applicability, is less prone to errors, and effectively improves the overall acceptance efficiency.

[0046] Furthermore, the first-level task termination request is sent to the substation microcomputer error prevention system while timing is performed and determining whether the reset response is received;

[0047] If the reset response is not received and the timing duration exceeds the third preset waiting duration, the first-level task termination request is resent.

[0048] From the above description, it can be seen that when making a first-level task termination request, a third preset waiting time is set as the waiting time for the control master station to wait for the response of the substation microcomputer error prevention system. After the timeout, the first-level task termination request is resent to confirm that the substation microcomputer error prevention system can correctly receive or respond, avoiding the control master station wasting too much waiting time due to not receiving a response, making the overall acceptance process more perfect.

[0049] Further, the first-level task selection request includes the acceptance device object and the device serial number;

[0050] The substation microcomputer error prevention system performs information verification and initialization operations on the first-level acceptance task corresponding to the first-level task selection request and returns a first-level task response, specifically including:

[0051] Verify the acceptance device object and the device serial number, if the verification is successful, perform a system self-check, if the verification fails, return the first-level task response as acceptance device object information error;

[0052] If the system self-check succeeds, the acceptance device object is initialized and the first-level task response is returned as passed; if the system self-check fails, the first-level task response is returned as system self-check failed.

[0053] From the above description, it can be seen that the substation microcomputer error prevention system performs a system self-check every time during the information verification and initialization operation of the first-level acceptance task to ensure the normal operation of its own parts.

[0054] Furthermore, the substation microcomputer error prevention system performs timing while returning the primary task response and determines whether the secondary task execution request is received;

[0055] If the secondary task execution request is not received and the timing duration exceeds the fourth preset waiting duration, a reset operation is performed.

[0056] From the above description, it can be seen that while returning the first-level task response to the control main station, the substation microcomputer error prevention system performs a timing wait for up to the fourth preset waiting time, which helps to determine whether an abnormality occurs in the control station.

[0057] Please refer to Figure 2 , Figure 4 as well as Figure 6 , a power grid error-proof information access automatic acceptance system 1, comprising a master station error-proof information acceptance function module 2 arranged at a control master station;

[0058] The master station error-proof information acceptance function module 2 is used to execute the above-mentioned automatic acceptance method for error-proof information access of a power grid.

[0059] From the above description, it can be seen that the beneficial effects of the present invention are: defining the anti-error information access acceptance task according to the acceptance equipment object, acceptance task type and other information, and grading and sorting the anti-error information access acceptance task, and then automatically verifying the interactive information, without the need to set up a dedicated automatic acceptance device in the substation; solving the verification strategy consistency problem of the control master station and the substation through task setting, and making the acceptance process of the control master station less prone to disorder through serialization processing, which makes up for the lack of coordination and interaction between the control master station and the substation, and improves the fault tolerance and anti-interference of the anti-error information access acceptance.

[0060] Furthermore, it also includes a substation error prevention information acceptance function module 3 of the substation microcomputer error prevention system;

[0061] The main station error-proof information acceptance function module 2 is connected to the substation error-proof information acceptance function module 3;

[0062] The substation error prevention information acceptance function module 3 is used to execute the above-mentioned automatic acceptance method for error prevention information access of a power grid:

[0063] Check the acceptance device object and device serial number. If the check succeeds, perform a system self-check. If the check fails, return a first-level task response indicating that the acceptance device object information is wrong.

[0064] If the system self-check succeeds, the acceptance device object is initialized and the first-level task response is returned as passed. If the system self-check fails, the first-level task response is returned as system self-check failure.

[0065] A method and system for automatic acceptance of power grid error-proof information access of the present invention can be applied to the scenario of error-proof information access of master and substation, and is described below through specific implementation methods:

[0066] Please refer to Figure 1 , Figure 3 and Figure 5 , Embodiment 1 of the present invention is:

[0067] A method for automatically accepting and checking false information access to a power grid, such as Figure 1 As shown, the steps include:

[0068] S1. Set the anti-error information access acceptance task according to the acceptance equipment object, acceptance task type and acceptance task status;

[0069] In this embodiment, the acceptance device object, acceptance task type and acceptance task status are specifically defined as follows:

[0070] Equipment to be accepted: including switches, knife switches, temporary grounding wires, mesh doors, trolleys and other equipment;

[0071] Acceptance task types: divided into status verification tasks and unlocking / locking test tasks;

[0072] Acceptance task status: For status verification tasks, it refers to the various operating states of the equipment object; for unlocking / locking test tasks, it corresponds to the unlocking and locking operations of the equipment object.

[0073] S2. Setting a first-level acceptance task including acceptance equipment object information and acceptance task type information, setting a second-level acceptance task including acceptance equipment object information, acceptance task type information and acceptance task status information, and combining a preset number of second-level acceptance tasks with the same acceptance equipment object and acceptance task type into a first-level acceptance task;

[0074] In this embodiment, the first-level acceptance task can be described as a two-tuple including acceptance device object information and acceptance task type information; the second-level acceptance task can be described as a three-tuple including acceptance device object information, acceptance task type information and acceptance task status information. A preset number of second-level acceptance tasks with the same acceptance device object and acceptance task type are combined into a first-level acceptance task, that is, the second-level acceptance tasks with the same acceptance device object and acceptance task type belong to the same first-level acceptance task, and then according to the different acceptance device object information and acceptance task type information, there are multiple different first-level acceptance tasks.

[0075] S3, sorting two or more first-level acceptance tasks to obtain a task sequence;

[0076] S4. Take out the first-level acceptance tasks one by one in the order of the task sequence, and automatically verify the interactive information with the substation microcomputer error prevention system based on the first-level acceptance task.

[0077] In this embodiment, combined with Figure 3 and Figure 5 As shown, the automatic verification of interactive information mainly includes three links: first-level task selection request and response, second-level task execution request and response, and first-level task termination request and response.

[0078] The first-level task selection request and response specifically include the following:

[0079] The control master station sends a first-level task selection request to the substation microcomputer error prevention system, which verifies and initializes the first-level acceptance task corresponding to the first-level task selection request and returns a first-level task response; wherein the first-level task selection request includes the acceptance equipment object and equipment serial number.

[0080] After receiving the first-level task selection request, the substation microcomputer error prevention system first checks the acceptance equipment object and equipment serial number. If the verification is successful, the system self-checks. If the verification fails, the first-level task response is returned as an acceptance equipment object information error.

[0081] The system self-check includes checking whether the communication status between the information source simulation function module and the real-time data processing function module and the communication status between the information source simulation function module and the remote control locking controller function module are normal; if the system self-check is successful, the acceptance device object is initialized and the first-level task response is returned as passed; if the system self-check fails, the first-level task response is returned as system self-check failure.

[0082] The initialization operation is to set the task status, task equipment and task type of the first-level acceptance task; among them, for equipment status verification tasks, the initial status of the corresponding equipment should be set to the pre-set status; for equipment unlocking test tasks, the corresponding equipment should be set to the "locking operation" status and the sole operation right setting should be restored.

[0083] The secondary task execution request and response specifically include the following:

[0084] The control master station sends a secondary task execution request to the substation microcomputer error prevention system when the primary task response is passed; the secondary task execution request contains secondary task attribute information such as acceptance equipment object, acceptance task type and acceptance task status.

[0085] After receiving the request to execute the secondary acceptance task, the substation microcomputer error prevention system first checks the current status of the primary acceptance task of the system: if the system currently has "no primary acceptance task", it refuses to accept the secondary acceptance task and returns an error response of "no primary acceptance task at present"; if the system currently has "a primary acceptance task", it continues to check the secondary acceptance task attributes: if the acceptance device object attributes and acceptance task type attributes of the requested secondary acceptance task are exactly the same as the acceptance device object attributes and acceptance task type attributes of the system's current primary acceptance task, it continues to check the acceptance task status attributes of the secondary acceptance task; otherwise, it refuses to accept the secondary acceptance task and returns an error response of "the requested secondary acceptance task does not belong to the current primary acceptance task".

[0086] The acceptance task status attributes of the secondary acceptance task checked by the substation microcomputer anti-error system include: if the acceptance task status is consistent with the current status of the equipment, an error response of "task error, the requested task status is consistent with the current status" is returned; otherwise, the next step is performed according to the different acceptance task statuses; for equipment status verification tasks: the information source simulation function module communicates with the real-time data processing function module, and the equipment status is set to the acceptance task status in the real-time database of the substation microcomputer anti-error system. If the equipment status is set normally, a correct response is returned to the control master station, otherwise an error response of "equipment status transmission abnormality" is returned; for unlocking / locking test tasks, the correct response is directly returned.

[0087] The control master station performs the secondary acceptance task when the secondary task response is passed: For equipment status verification tasks: check whether the equipment status in the real-time database of the control master station system has changed as expected, check whether the equipment status display on the monitoring screen is as expected, and check whether the expected equipment status change events are generated in the real-time alarm event window; For unlocking / locking test tasks, issue test unlocking / locking instructions and check the equipment unlocking / locking status in the real-time database.

[0088] The first-level task termination request and response specifically include the following:

[0089] The control master station sends a first-level task termination request to the substation microcomputer error prevention system; the first-level task termination request also includes the first-level acceptance task attribute information and the equipment serial number information of the acceptance equipment object

[0090] After receiving the termination request of the first-level acceptance task, the substation microcomputer error prevention system first checks the current first-level acceptance task status of the system: if the system currently has "no first-level acceptance task", it refuses to accept the termination request of the first-level acceptance task and returns an error response of "no first-level acceptance task at present"; if the system currently has "a first-level acceptance task", it continues to check the first-level acceptance task to be terminated: if the acceptance device object attributes and acceptance task type attributes of the first-level acceptance task requested to be terminated are consistent with the acceptance device object attributes and acceptance task type attributes of the current first-level acceptance task of the system, a reset operation is performed; otherwise, an error response of "task error, the first-level acceptance task requested to be terminated is not the current task" is returned to the control master station;

[0091] The substation microcomputer error prevention system performs reset operations including: for status verification tasks, the equipment status should be restored to the normal business status; for unlocking test tasks, the corresponding equipment is set to the "locked" state and the sole operation right setting is restored. If the above reset operation is successfully executed, the correct response of "normal reset of substation" is returned to the control master station, otherwise the error response of "abnormal reset operation" is returned to the control master station.

[0092] Please refer to 3 and Figure 5 , Embodiment 2 of the present invention is:

[0093] A method for automatic acceptance of power grid error-proof information access, based on the above-mentioned second embodiment, sets a timeout processing mechanism for the three links of primary task selection request and response, secondary task execution request and response, and primary task termination request and response in the first embodiment, and specifically includes the following contents:

[0094] It should be noted that, in order to better illustrate the content of the present embodiment, the time factor of the timeout processing mechanism is defined, as shown in Table 1. The value of Tc includes: for status check tasks, including the time for the master station to check and record the check elements reflecting the device status such as databases, human-machine interface graphics, and matters; for unlocking test tasks, including the unlocking test time and the time for the master station to check and record the unlocking status of the device and the setting of the operation right.

[0095] Table 1 Definition of time symbols related to the automatic verification process of the master-slave station interaction information

[0096]

[0097] The timeout settings in the first-level task selection request and response include the following:

[0098] The control master station sends a first-level task selection request to the substation microcomputer anti-error system, and at the same time, it counts and determines whether a first-level task response is received; if a first-level task response is not received and the timing duration exceeds the first preset waiting duration, the first-level task selection request is resent; wherein, after the control master station sends a first-level task selection request, under normal circumstances, the substation response should be received within (2Tx+Ti) time. Set the master station waiting delay T1, that is, the first preset waiting duration, T1>2Tx+Ti.

[0099] In addition, the substation computer error prevention system will time and determine whether a secondary task execution request is received while returning the primary task response; if the secondary task execution request is not received and the timing duration exceeds the fourth preset waiting time, a reset operation will be performed. After the substation responds to the primary task selection request, it waits for the master station to issue subsequent instructions (secondary task execution request / primary task termination request), and sets the substation waiting delay T2, that is, the fourth preset waiting time, T2>2Tx.

[0100] The timeout settings in the secondary task execution request and response include the following:

[0101] When the control master station sends a secondary task execution request to the substation microcomputer error prevention system, it performs timing and determines whether a secondary task response is received; if no secondary task response is received and the timing duration exceeds the second preset waiting duration, the secondary task execution request is resent; wherein, the control master station sets the second preset waiting duration according to the acceptance task status of the secondary acceptance task corresponding to the secondary task execution request, that is, after the control master station sends the secondary task execution request, under normal circumstances, the substation response should be received within (2Tx+Td) time for equipment status verification tasks; and the substation response should be received within 2Tx time for equipment unlocking test tasks. Set the master station waiting delay T3, that is, the second preset waiting duration, for equipment status verification tasks, T3>2Tx+Td; for equipment unlocking test tasks, T3>2Tx.

[0102] In addition, after the substation responds to the secondary task execution request, it waits for the control master station to issue subsequent instructions (secondary task execution request / primary task termination request), and sets the substation waiting delay T4, T4>2Tx+Tc. It is stipulated that after the substation responds to the secondary task execution request, if it does not receive the subsequent instructions (secondary task execution request / primary task termination request) from the master station within the T4 delay, the reset operation is performed.

[0103] The timeout settings for the three links of the first-level task termination request and response include the following:

[0104] The control master station sends a first-level task termination request to the substation microcomputer anti-error system, and at the same time, it counts and determines whether a reset response is received; if no reset response is received and the timing duration exceeds the third preset waiting duration, the first-level task termination request is resent; wherein, after the master station sends the first-level task termination request, under normal circumstances, the substation response message should be received within (2Tx+Tr) time. Set the master station waiting delay T5, T5>2Tx+Tr.

[0105] Please refer to Figure 2 , Figure 4 as well as Figure 6 , Embodiment 2 of the present invention is:

[0106] A power grid error-proof information access automatic acceptance system 1, such as Figure 6 As shown, it includes a master station error prevention information acceptance function module 2 and a substation error prevention information acceptance function module 3 which are respectively arranged in the control master station and the substation microcomputer error prevention system;

[0107] The master station error information prevention acceptance function module 2 is in communication connection with the substation error information prevention acceptance function module 3, and the master station error information prevention acceptance function module 2 is used to execute a power grid error information prevention access automatic acceptance method of embodiment one or two.

[0108] In this embodiment, if Figure 2As shown, the implementation principle of the acceptance function of the master station anti-error information acceptance function module 2 is as follows:

[0109] 1. Control the acceptance of the error-proof equipment status in the memory database of the master station system

[0110] The error prevention data processing service obtains the status information of the temporary grounding wire, network (cabinet) door and other error prevention equipment uploaded by the substation microcomputer error prevention system from the error prevention data communication service, and the operation unlocking status information of the switch and other equipment, and writes it to the shared memory library. The comprehensive data service reads the status of the error prevention equipment and the operation unlocking status of the switch and other equipment from the shared memory library, and sends it to the real-time data service.

[0111] The main station anti-error information acceptance function module 2 interacts with the integrated data service and the real-time data service to obtain the anti-error device status and the operation unlocking status of equipment such as knife switches in the shared memory library and the real-time database respectively, thereby realizing the acceptance of the anti-error device status and the operation unlocking status of equipment such as knife switches in the shared memory library and the real-time database.

[0112] 2. Acceptance of display status of error-proof equipment graphic elements on the human-machine interface of the control master station system

[0113] The real-time data service sends the error prevention device status to the human-machine interface process, thereby realizing real-time update of the error prevention device graphic element display status on the human-machine interface.

[0114] The main station error prevention information acceptance function module 2 interacts with the human-machine interface process to check whether the error prevention device graphic element display on the human-machine interface has the expected change, thereby realizing the acceptance of the error prevention device graphic element display status on the human-machine interface.

[0115] 3. Acceptance of error-proof equipment status changes in the alarm window of the human-machine interface of the control master station system

[0116] The error prevention data processing service obtains the status information of the error prevention equipment such as temporary grounding wires and network (cabinet) doors uploaded by the substation microcomputer error prevention system from the error prevention data communication service. If the error prevention equipment status changes, the error prevention equipment status change event is generated and pushed to the real-time event service. The real-time event service then distributes the error prevention equipment status change event to the human-machine interface process.

[0117] The main station error prevention information acceptance function module 2 interacts with the human-machine interface process to check whether the expected error prevention device state change event occurs in the human-machine interface alarm event window, thereby realizing the acceptance of the error prevention device state change alarm event.

[0118] 4. Perform the unlocking operation test on the equipment on the control master station system

[0119] The master station anti-error information acceptance function module 2 sends the unlocking test instruction of the specified equipment to the anti-error data processing service, and the anti-error data processing service issues the instruction to the anti-error data communication service. Through the interaction of the master-substation anti-error data communication service, the equipment unlocking test instruction is finally sent to the substation microcomputer anti-error system for execution, thereby completing the unlocking operation test of the equipment.

[0120] In this embodiment, if Figure 4 As shown, the implementation principle of the acceptance function of the substation anti-error information acceptance function module 3 is as follows:

[0121] 1. Acceptance of equipment status to prevent errors

[0122] The substation error prevention information automatic acceptance function module responds to the secondary task of equipment status verification issued by the master station, and writes the error prevention equipment status into the real-time database by interacting with the real-time data service, completing the signal simulation required for equipment status acceptance. The real-time data service interacts with the error prevention data communication service to upload the error prevention equipment status to the control master station.

[0123] 2. Equipment unlocking test

[0124] The substation anti-error information automatic acceptance function module responds to the equipment unlocking test tasks issued by the master station. By interacting with the real-time data service, it completes the initialization operation before the start of the task and the reset operation before the end of the task (including restoring the sole operation right setting of the equipment and completing the locking operation of the equipment).

[0125] In this embodiment, the master station error prevention information acceptance function module 2 and the substation error prevention information acceptance function module 3 are connected in communication by multiplexing the master-substation error prevention data communication link.

[0126] In summary, the present invention provides a method and system for automatic acceptance of anti-error information access in a power grid, which defines anti-error information access acceptance tasks according to information such as acceptance equipment objects and acceptance task types, and classifies and sorts the anti-error information access acceptance tasks, and then automatically verifies the interactive information, without the need to set up a dedicated automatic acceptance device in the substation; the problem of consistency in verification strategies between the control master station and the substation is solved through task-based setting, and the acceptance process of the control master station is less prone to disorder through serialization processing, which makes up for the defect of insufficient coordination and interaction between the control master station and the substation, and improves the fault tolerance and anti-interference of anti-error information access acceptance.

[0127] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
