Description

Technical Field

[0001] The present application relates to the technical field of substations, and in particular to a substation anti-mistaken locking system and a substation anti-mistaken locking method. Background Art

[0002] The anti-error locking system of the substation has become an indispensable part of the anti-error management and control of the substation. It can effectively standardize the operating procedures of the substation switching and prevent the misoperation of the substation operation and maintenance personnel. Therefore, it has been widely used in the substation field.

[0003] The computer anti-error locking system will face transformation and replacement due to the requirements of operating life or function upgrade. The actual transformation is more about replacing the anti-error locks at intervals in combination with the substation power outage plan, and the transformation cycle is relatively long. The manufacturers of the new and old anti-error systems are different, and the product upgrades have caused incompatibility between the new and old computer keys and lock interfaces. The equipment that has completed the anti-error lock transformation and the equipment that has not completed the anti-error lock transformation must be operated by issuing operation tickets through the new anti-error system and the old anti-error system respectively, and cannot be completed through a set of anti-error systems. When an operation ticket involves mixed operations of equipment that has completed the anti-error lock transformation and equipment that has not completed the anti-error lock transformation, it is necessary to issue and review tickets on the new and old anti-error hosts respectively, and the operation efficiency is low.

[0004] In addition, during the transformation of the anti-error locking system, the monitoring system can only communicate with one of the anti-error systems to realize the interaction of the primary equipment status, secondary equipment status and operation locking information of the substation. The other anti-error system is not actually connected, and its equipment status is set by the operation and maintenance personnel instead of being updated in real time. Therefore, it may cause accidents due to status errors, allowing operations that do not meet the anti-error logic to be executed.

[0005] The above information disclosed in the Background section is only for enhancement of understanding of the background of the present application and therefore it may contain information that does not constitute the prior art that is already known to a person of ordinary skill in the art.

[0032] The specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0033] Figure 1 A device block diagram of a substation anti-mislocking system according to an exemplary embodiment of the present application is shown. Figure 1 The substation anti-error locking system shown includes an anti-error host unit 101 , an unmodified unit 103 and a modified unit 105 .

[0034] The error prevention host unit 101 is configured to generate and send an operation task, wherein the operation task includes a first operation step and / or a second operation step.

[0035] The unmodified unit 103 is provided with a first computer key of the substation, and is configured to receive a first operation step from the anti-error host unit 101, and operate the corresponding unmodified lock with the first computer key according to the first operation step.

[0036] The modified unit 105 is provided with a second computer key of the substation, and the modified unit 105 is configured to receive a second operation step from the anti-error host unit 101, and operate the corresponding modified lock with the second computer key according to the second operation step.

[0037] In a specific embodiment, the transformation of the substation is to replace the anti-error locks at intervals in combination with the substation outage plan. According to an embodiment of the present application, before generating the operation task, the anti-error host unit 101 is also configured to obtain the substation equipment status from the equipment monitoring unit.

[0038] In other embodiments, before the error prevention host unit 101 generates an operation task, the error prevention host unit 101 is further configured to start the operation ticket to perform an operation ticket preview, and only generate the operation task after the error prevention logic check passes.

[0039] According to the embodiments of the present application, Figure 2In the schematic diagram of the substation anti-error locking system architecture shown, the unmodified unit 103 includes an unmodified anti-error host subunit. The unmodified anti-error host subunit is configured to receive the first operation step from the anti-error host unit 101, and send the first operation step to the first computer key, so as to operate the unmodified lock locally through the first computer key. The first computer key is a computer key that has not been updated, and the second computer key is a computer key that has been updated.

[0040] According to an embodiment of the present application, the anti-error host unit 101 is further configured to obtain device status information of the substation from the device monitoring unit, and send the device status information to the first computer key or the second computer key.

[0041] In some specific embodiments, the unmodified error prevention host subunit is further configured to obtain the device status information and the first operation step of the substation from the error prevention host unit 101 through the device number.

[0042] In other embodiments, Figure 3 In the schematic diagram of the architecture of another substation anti-error locking system shown, the anti-error host unit 101 is further configured to directly send the first operation step to the first computer key in the unmodified unit.

[0043] According to an embodiment of the present application, the operation task generated by the anti-error host unit 101 also includes a remote control operation step. The anti-error host unit 101 is further configured to lock or unlock the operation authority of the device monitoring unit to the unmodified unit 103 or the modified unit 105 according to the remote control operation step, so as to ensure that at the same time, only the device monitoring unit is allowed to have the remote control operation authority for the device corresponding to the remote control operation step. In some embodiments, the anti-error host unit 101 is further configured to issue the operation tasks to the unmodified unit 103 and the modified unit 105 so that at the same time, only one computer key among the first computer key and the second computer key has the operation authority. That is, at the same time, only one computer key executes the operation instruction from the user, and the operation and maintenance personnel are only allowed to perform on-site operation on one of the first computer key and the second computer key at the same time, so as to prevent the occurrence of erroneous operation caused by the failure to meet the anti-error logic.

[0044] In a specific embodiment, the operation task generated by the error prevention host unit 101 also includes operation steps for the primary equipment of the substation and operation steps for the secondary equipment of the substation. Figure 1The embodiment shown allows operation and maintenance personnel to generate operation tasks including completed and uncompleted modified lock devices through only one set of anti-error system, namely, the anti-error host unit, during the modification of the substation anti-error system. The anti-error host unit controls the operation steps in the operation tasks to be strictly executed in sequence, thereby ensuring the correct execution of each operation step and improving the safety of the operation.

[0045] According to some embodiments, during the transformation of the substation anti-error system, the operation and maintenance personnel only need to use one anti-error system, that is, the anti-error host unit, to generate operation tasks including completed and uncompleted transformation of lock devices, and control the operation steps in the operation tasks through the anti-error host unit to be strictly executed in sequence, thereby ensuring the correct execution of each operation step and avoiding the situation in the prior art where multiple anti-error systems are required to issue invoices and conduct audits separately, thereby reducing the pressure on the operation and maintenance staff to review the process and improving the operation efficiency.

[0046] Figure 4 A flow chart of a substation anti-mistaken locking method of a substation anti-mistaken locking system according to an exemplary embodiment of the present application is shown. Figure 3 The method shown includes step S401, step S403 and step S405.

[0047] like Figure 4 As shown, in step S401, an operation task is generated and sent using the error-prevention host unit, wherein the operation task includes a first operation step and / or a second operation step.

[0048] In step S403, the first operation step from the error-prevention host unit is received by the unmodified unit, and the first computer key is used to operate the corresponding unmodified lock according to the first operation step.

[0049] In step S405, the modified unit receives the second operation step from the error-prevention host unit, and according to the second operation step, the second computer key is used to operate the corresponding modified lock.

[0050] Figure 5 A schematic diagram of primary wiring of two intervals of a 110kV I bus of a substation according to an exemplary embodiment of the present application is shown. Figure 5 The five-protection transformation of the A-line and B-line intervals of the 110kVⅠbus substation is shown as follows Figure 6 shown.

[0051] like Figure 5 and Figure 6As shown, the locks of the relevant equipment in the A-line interval have been modified, and the second computer key is used when performing local operations on the relevant equipment in the A-line interval; the circuit breaker 152, the knife switch 1521, and the knife switch 1526 in the B-line interval have not been modified, and the first computer key is used when performing local operations on them, and the locks of the ground switches 15230, 15240, and 15260 have been modified, and the second computer key is used when performing local operations on them.

[0052] When the anti-error system is being modified, if the second computer key and the first computer key are from different manufacturers or the first computer key is not compatible with the anti-error host unit due to product replacement, two sets of anti-error hosts are used to connect to the computer key. Figure 2 As shown, the anti-error host unit communicates with the equipment monitoring unit to obtain the equipment status information once, and locks the operation authority of the equipment monitoring unit. At the same time, the unmodified anti-error host subunit is connected as a substation of the anti-error host unit to obtain the equipment status information and receive the operation tasks of the unmodified equipment.

[0053] Since the premise of the anti-error system to perform anti-error logic verification is to obtain the correct device status, and the anti-error logic verification may use the status of non-interval (modified) devices, the unmodified anti-error host subunit needs to obtain the full device status. That is, the anti-error host unit obtains the full device status from the monitoring device unit and forwards it to the unmodified anti-error host subunit.

[0054] In a specific embodiment, the operation and maintenance personnel start the operation ticket rehearsal on the error prevention host unit, and generate the operation task after the error prevention logic verification. The operation ticket is a collection of all operation tasks, and the operation tasks include local operation tasks and remote control operation tasks. The local operation tasks include modified equipment operation tasks and / or unmodified equipment operation tasks.

[0055] After the operation task is started, the remote control operation task is used to enable the equipment monitoring unit for remote control; the operation task of the modified equipment is directly sent to the second computer key through the anti-error host unit using the local operation task, and the operation task of the unmodified equipment is forwarded to the first computer key through the unmodified anti-error host subunit, so as to allow the operating personnel to perform local operation with the corresponding computer key.

[0056] According to some embodiments, when the on-site operation task includes both the modified equipment operation task and the unmodified equipment operation task, such as the B line interval is overhauled by the hot standby switch, and the unlocking interface of the key used is different, the anti-error host unit downloads the operation task of closing the 15230 ground switch on the bus side of the B line circuit breaker and the 15240 ground switch on the line side of the B line circuit breaker to the second computer key, and downloads the operation task of opening the 1521 switch on the bus side of the B line and the 1526 switch on the line side of the B line to the first computer key via the unmodified anti-error host subunit. According to the embodiment of the present application, only one of the computer keys is allowed to operate at the same time to prevent the occurrence of misoperation accidents caused by the failure to meet the anti-error logic.

[0057] In this embodiment, a mixed operation of equipment with completed and uncompleted anti-error lock modification is completed through one operation ticket. Compared with the prior art that uses two operation tickets for separate operations, or one of the anti-error host machines is offline during the modification, the invoicing and operation efficiency and safety of this embodiment are higher.

[0058] like Figure 3 As shown, when the anti-error system is modified, if the second computer key and the first computer key are compatible with the anti-error host unit, the anti-error host unit is used to access the two sets of computer keys. The anti-error host unit communicates with the device monitoring unit to obtain the device status information once, and locks or unlocks the device monitoring unit's operation authority to the first computer key and the second computer key, to ensure that at the same time, only the device monitoring unit is allowed to have remote control operation authority for the device corresponding to the remote control operation step. Figure 2 The difference is that the on-site operation task configures the association between the equipment and computer keys of the substation through the anti-error host unit, and directly sends the operation tasks of the modified equipment and / or unmodified equipment to the second computer key and the first computer key, allowing the operating personnel to operate on-site with the corresponding computer key.

[0059] For example, when the on-site operation task includes both modified equipment and unmodified equipment, if the 152 interval is overhauled by the hot standby switch and the unlocking interface of the key used is different, the anti-error host unit will download the operation task of closing the 15230 grounding switch on the bus side of Line B circuit breaker and the 15240 grounding switch on the line side of Line B circuit breaker to the second computer key, and the operation task of opening the 1521 switch on the bus side of Line B and the 1526 switch on the line side of Line B will be directly downloaded to the first computer key, and only one of the computer keys is allowed to operate at the same time to prevent erroneous operation caused by failure to meet the anti-error logic.

[0060] In this embodiment, the operation authority of the equipment monitoring unit is the operation permission when the operation step selects remote control execution, and the unlocking authority is the operation permission of the computer key when the local operation is selected. The operation authority may be in the monitoring system or in the computer key, but only one party can have the operation authority at the same time, and only one computer key can have the operation authority at the same time for the first computer key and the second computer key. After the anti-error host unit opens the operation ticket and starts execution, it will allow the equipment in the first operation step to have the operation authority. After the first operation step is completed, the first operation authority is locked and the second operation authority is allowed until all the operation steps are completed.

[0061] According to the embodiments of the present application, during the process of modifying the anti-error system, operation and maintenance personnel can uniformly issue operation tickets on the anti-error host unit, and the anti-error host unit controls the operation steps to be strictly executed in sequence, thereby ensuring that the functions of the anti-error system during the modification process are complete.
