[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] In an exemplary embodiment, Figure 1 As shown, a temporary grounding line anti-misoperation logic locking method for an energy storage power station is provided, and the method is applied to a temporary grounding line anti-misoperation logic locking system as an example for explanation. The temporary grounding line anti-misoperation logic locking system may include a first transformer system, and the first transformer system may include a first key replacement box, an SFC output transformer, and an SFC input transformer, including:

[0048] Step 101: When it is detected that the first security key is placed in the first key replacement box, a release operation is performed on the first mechanical key and the second mechanical key.

[0049] As an example, the first key replacement box may be a programmable mechanical key replacement device.

[0050] As an example, the first transformer system may be a SFC (Static Frequency Converter) input / output transformer system.

[0051] Among them, the first mechanical key can be used to unlock the grounding pile on the low-voltage side of the SFC output transformer, releasing the first locking key, and the first locking key can be used to unlock the grounding pile on the high-voltage side of the SFC output transformer, releasing the second locking key; the second mechanical key can be used to unlock the grounding pile on the low-voltage side of the SFC input transformer, releasing the third locking key, and the third locking key can be used to unlock the grounding pile on the high-voltage side of the SFC input transformer, releasing the fourth locking key.

[0052] In actual applications, the programmable mechanical key replacement device can be used to compulsorily solidify the operating procedures for installation and removal of all temporary grounding wires of the SFC input / output transformer in the energy-storage power station according to the newly added preset logical conditions, so as to realize the newly added logical conditions for all temporary grounding wires of the SFC input / output transformer in the energy-storage power station and compulsorily solidify them.

[0053] For example, for the SFC input / output transformer system in the energy storage power station, the following mechanical locking logic can be added:

[0054] A new key replacement box A2 (i.e. the first key replacement box) is added, and the K011 (i.e. the first security key) security key can be used to replace the K031 and K034 mechanical keys (i.e. the first mechanical key and the second mechanical key) respectively.

[0055] 1. After closing the SFC#1 and #2 input switch grounding switches, you can use K031 to unlock the grounding pile on the low-voltage side of the SFC output transformer, install a set of three-phase short-circuit grounding wires on the low-voltage side of the SFC output transformer, and pull out the grounding pile locking key K032 (i.e. the first locking key);

[0056] 2. By using K032 to unlock the grounding pile on the high-voltage side of the SFC output transformer, a set of three-phase short-circuit grounding wires can be installed on the high-voltage side of the SFC output transformer, and the grounding pile locking key K033 (i.e. the second locking key) can be pulled out;

[0057] 3. By using the K034 mechanical key to unlock the grounding pile on the low-voltage side of the SFC input transformer, a set of three-phase short-circuit grounding wires can be installed on the low-voltage side of the SFC output transformer, and the grounding pile locking key K035 (i.e. the third locking key) can be pulled out;

[0058] 4. By using K035 to unlock the grounding pile on the high-voltage side of the SFC input transformer, a set of three-phase short-circuit grounding wires can be installed on the high-voltage side of the SFC input transformer, and the grounding pile locking key K036 (the fourth locking key) can be pulled out as a safety key.

[0059] In one example, the mechanical lock of the programmable mechanical key replacement device meets the requirements of the technical conditions for mechanical locks for high-voltage switchgear. The programmable mechanical key replacement device can be composed of a lock cylinder and a cam device, wherein each main key can be equipped with a spare key; a key can only be inserted into one lock hole at a time, the mechanical key code is unique, and the keys of each system cannot be used interchangeably. By uniformly coding the keys of the entire system, the lock can be prevented from being opened by mistake.

[0060] In another example, the requirements for grounding piles may include: the structural design and installation of the grounding pile lock must comply with the relevant requirements of the portable grounding wire standard to make the grounding wire easy and reliable to disassemble and assemble, and it is necessary to ensure that the grounding wire grounding head is in good contact with the grounding pile and meet the overcurrent requirements of the grounding wire of the corresponding voltage level; the grounding pile needs to be modified in combination with the actual installation conditions on site so that the grounding pile will not affect the original performance of the original equipment / facility after it is built, and will not affect the normal operation, control and operation of the equipment, and a grounding pile logo can be set for marking.

[0061] In the logic locking method for preventing misoperation of the temporary grounding wire of the above-mentioned energy-storage power station, by executing the release operation of the first mechanical key and the second mechanical key when detecting that the first safety key is placed in the first key replacement box, the programmable mechanical key replacement device is used to compulsorily solidify the logical conditions and operating procedures for the installation and removal of all temporary grounding wires, which can avoid the risks of installing temporary grounding wires or supplying power with grounding wires under power through technical means.

[0062] In an exemplary embodiment, the following steps may also be included:

[0063] When performing the isolation release task for the first transformer system, if it is detected that the first mechanical key and the second mechanical key are placed in the first key replacement box, a release operation of the first security key is performed.

[0064] In the specific implementation, for the SFC input / output transformer system in the energy storage power station, the isolation release operation procedure opposite to the mechanical interlocking logic can be used according to the newly added mechanical interlocking logic to perform the isolation release task for the first transformer system; for example, in the key replacement box A2 (i.e., the first key replacement box), the K031 and K034 mechanical keys (i.e., the first mechanical key and the second mechanical key) can be used to replace the K011 (i.e., the first safety key) safety key. This realizes the mandatory solidification of the logical conditions and operation procedures for the installation and removal of all temporary grounding wires in the SFC input / output transformer system.

[0065] In an exemplary embodiment, the temporary grounding line anti-misoperation logic locking system may further include a main transformer system, which may include a second key replacement box, a unit excitation transformer, an input switch reactor, and a plant high-voltage transformer reactor. Figure 2 As shown, the following steps may also be included:

[0066] Step 201: When it is detected that the second security key is placed in the second key replacement box, a release operation is performed on the third mechanical key, the fourth mechanical key, and the fifth mechanical key.

[0067] As an example, the second key replacement box may be a programmable mechanical key replacement device.

[0068] As an example, the main transformer system may be a 220 kV #1 main transformer system.

[0069] Among them, the third mechanical key can be used to unlock the grounding pile on the low-voltage side of the unit excitation transformer and release the fifth locking key; the fourth mechanical key can be used to unlock the grounding pile of the input switch reactor and release the sixth locking key; the fifth mechanical key can be used to unlock the grounding pile of the plant high-voltage transformer reactor and release the seventh locking key.

[0070] In one example, the programmable mechanical key replacement device can be used to compulsorily solidify the operation procedures for installing and removing all temporary grounding wires of the excitation transformer and the low-voltage side reactor of the energy storage power station unit according to the newly added preset logical conditions. Thus, it is possible to add the logical conditions for the operation of all temporary grounding wires of the excitation transformer and the low-voltage side reactor of the main transformer of the energy storage power station unit and compulsorily solidify them.

[0071] Specifically, for the 220kV#1 main transformer system, the following mechanical interlocking logic can be added:

[0072] A new key replacement box A1 (i.e. the second key replacement box) is added, which can use the K177 security key (i.e. the second security key) to replace the K190, K192, and K194 mechanical keys (i.e. the third mechanical key, the fourth mechanical key, and the fifth mechanical key).

[0073] 1. After using the mechanical key K178-K183 to open the cabinet door of #1 excitation transformer, you can use K190 to unlock the grounding pile on the low-voltage side of #1 unit excitation transformer. You can install a set of three-phase short-circuit grounding wires on the low-voltage side of #1 unit excitation transformer, and pull out the grounding pile locking key K191 (the fifth locking key) as a safety key;

[0074] 2. After using mechanical keys K173 and K174 to open the fence gates of SFC #1 input switch reactor and #1 plant high-voltage transformer reactor, you can use K192 to unlock the grounding pile of SFC #1 input switch reactor, install a set of three-phase short-circuit grounding wires at SFC #1 input switch reactor, and pull out the grounding pile locking key K193 (the sixth locking key) as a safety key; by using K194 to unlock the grounding pile of #1 plant high-voltage transformer reactor, you can install a set of three-phase short-circuit grounding wires at #1 plant high-voltage transformer reactor, and pull out the grounding pile locking key K195 (the seventh locking key) as a safety key.

[0075] In an exemplary embodiment, the following steps may also be included:

[0076] When performing the isolation release task for the main transformer system, if it is detected that the third mechanical key, the fourth mechanical key, and the fifth mechanical key are placed in the second key replacement box, a release operation of the second security key is performed.

[0077] In actual application, for the 220kV#1 main transformer system, the isolation removal task for the main transformer system can be performed according to the newly added mechanical interlocking logic and the isolation removal operation procedure opposite to the mechanical interlocking logic; for example, in the key replacement box A1 (i.e. the second key replacement box), the K190, K192, K194 mechanical keys (i.e. the third mechanical key, the fourth mechanical key, and the fifth mechanical key) can be used to replace the K177 safety key (i.e. the second safety key). This realizes the mandatory solidification of the logical conditions and operation procedures for the installation and removal of all temporary grounding wires in the 220kV#1 main transformer system.

[0078] In an exemplary embodiment, the temporary grounding line anti-misoperation logic locking system further includes a second transformer system, which may include a unit self-use power distribution board transformer, and may also include the following steps:

[0079] When it is detected that the transformer cabinet door in the second transformer system is opened, an unlocking operation based on a third safety key is performed.

[0080] As an example, the second transformer system may be a 10 / 0.4kV #1 unit self-use power distribution panel #1 transformer system.

[0081] Among them, the third safety key can be used to unlock the grounding pile on the low-voltage side of the unit's own power distribution board transformer, releasing the eighth locking key, and the eighth locking key can be used to unlock the grounding pile on the high-voltage side of the unit's own power distribution board transformer, releasing the ninth locking key.

[0082] In actual application, the programmable mechanical key replacement device can be used to compulsorily solidify the installation and removal operation procedures of the temporary grounding wires on the high and low voltage sides of the 13.8 / 10kV plant high-voltage transformer and 10 / 0.4kV plant transformer in the energy storage power station according to the newly added preset logical conditions. In this way, the newly added logical conditions for the installation and removal of the temporary grounding wires on the high and low voltage sides of the plant high-voltage transformer and plant transformer of the energy storage power station can be realized and compulsorily solidified.

[0083] Specifically, for the 10 / 0.4kV #1 unit self-use power distribution board #1 transformer system in the energy storage power station, the following mechanical interlocking logic can be added:

[0084] 1. After using K895 and K894 to open the transformer cabinet door (i.e., when the transformer cabinet door in the second transformer system is detected to be opened), the original safety key K896 (i.e., the third safety key) can be used to unlock the grounding pile on the low-voltage side of the #1 transformer in the #1 unit's own power distribution board. A set of three-phase short-circuit grounding wires can be installed on the low-voltage side of the #1 transformer in the #1 unit's own power distribution board, and the grounding pile locking key K897 (i.e., the eighth locking key) can be pulled out;

[0085] 2. By using K897 to unlock the grounding pile on the high-voltage side of the #1 transformer in the #1 unit's own power distribution board, a set of three-phase short-circuit grounding wires can be installed on the high-voltage side of the #1 transformer in the #1 unit's own power distribution board, and the grounding pile locking key K898 (the ninth locking key) can be pulled out as a safety key.

[0086] In an optional embodiment, for the 10 / 0.4kV #1 unit self-use power distribution board #1 transformer system in the energy storage power station, the isolation release operation procedure opposite to the mechanical interlocking logic can be adopted according to the newly added mechanical interlocking logic to execute the isolation release task for the second transformer system.

[0087] In an exemplary embodiment, the temporary grounding line anti-misoperation logic locking system further includes a reactor system, which may include an SFC output reactor and a plant high-voltage transformer reactor, and may also include the following steps:

[0088] When it is detected that the fence door of the SFC output reactor is opened, an unlocking operation using a fourth security key is performed.

[0089] As an example, the reactor system may be a SFC output reactor system.

[0090] Among them, the fourth safety key can be used to unlock the grounding post of the SFC output inductor and release the tenth locking key.

[0091] In one example, the programmable mechanical key replacement device can be used to compulsorily solidify the installation and removal operation procedures of the temporary grounding wire of the SFC output reactor of the energy storage power station according to the newly added preset logical conditions. In this way, the logical conditions for all temporary grounding wires of the SFC output transformer of the energy storage power station can be added and compulsorily solidified.

[0092] In another example, for the SFC output reactor system of the energy storage power station, the following mechanical locking logic can be added:

[0093] After using K033 to open the fence door of the SFC output reactor (that is, when it is detected that the fence door of the SFC output reactor is opened), the grounding pile of the SFC output reactor can be unlocked by using the safety key K034 (that is, the fourth safety key), a set of three-phase short-circuit grounding wires can be installed at the SFC output reactor, and the grounding pile locking key K039 (that is, the tenth locking key) can be pulled out.

[0094] Optionally, for the SFC output reactor system of the energy storage power station, the isolation release task for the reactor system can be performed according to the newly added mechanical interlocking logic and using an isolation release operation procedure opposite to the mechanical interlocking logic.

[0095] In an optional embodiment, the temporary grounding wire anti-misoperation logic interlocking system may also include a 220kV four-circuit outgoing line system of an energy storage power station, and the operation procedures for installing and removing all temporary grounding wires of the 220kV four-circuit outgoing line of the energy storage power station may be forcibly solidified according to the newly added preset logic conditions by using a programmable mechanical key replacement device. Thus, the newly added logic conditions for all temporary grounding wires of the 220kV four-circuit outgoing line of the energy storage power station can be realized and forcibly solidified.

[0096] For example, for the 220kV four-circuit outgoing line system of the energy storage power station, the following mechanical interlocking logic can be added:

[0097] 1. A mechanical locking key K516 (newly added) can be strung onto the padlock key of the isolating knife switch 22516 on the line side of the 220kV storage II line switch as the starting key. After the isolating knife switch 22516 on the line side of the 220kV storage II line switch is locked in the open position, the padlock key and the K1516 (newly added) on it can be pulled out;

[0098] 2. Confirm that the line is powered off (check the line display to see that there is no power on the three phases; check the line voltage, current and power on the monitoring system);

[0099] 3. Use key K1516 to unlock the A-phase grounding pile of the 220kV storage II line outgoing line. After verifying that there is no voltage at the A-phase down conductor, install a set of single-phase short-circuit grounding wires, and then you can take out the locking key K1516A (newly added);

[0100] 4. Use key K1516A to unlock the B-phase grounding pile of the 220kV storage II line outgoing line. After verifying that there is no voltage at the B-phase down conductor, install a set of single-phase short-circuit grounding wires, and then you can take out the locking key K1516B (newly added);

[0101] 5. Use key K1516B to unlock the C-phase grounding pile of the 220kV storage II line. After verifying that there is no voltage at the C-phase down lead, install a set of single-phase short-circuit grounding wires. You can take out the locking key K1516C (newly added) K1516C as a safety key.

[0102] For another example, for the 220kV four-circuit outgoing line system of the energy storage power station, the isolation release operation procedure opposite to the mechanical interlocking logic can be used according to the newly added mechanical interlocking logic to execute the isolation release task for the 220kV four-circuit outgoing line system of the energy storage power station.

[0103] In an exemplary embodiment, Figure 3 As shown, another flow chart of a method for preventing misoperation of a temporary grounding line of an energy storage power station is provided. In this embodiment, the method includes the following steps:

[0104] In step 301, when it is detected that the first safety key is placed in the first key replacement box, the first mechanical key and the second mechanical key are released. In step 302, when performing the isolation release task for the first transformer system, if it is detected that the first mechanical key and the second mechanical key are placed in the first key replacement box, the first safety key is released. It should be noted that the specific definition of the above steps can be referred to the specific definition of the logic locking method for preventing misoperation of a temporary grounding line of an energy storage power station mentioned above, which will not be repeated here.

[0105] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0106] Based on the same inventive concept, the embodiment of the present application also provides a temporary grounding wire anti-misoperation logic interlocking device for an energy storage power station for implementing the above-mentioned temporary grounding wire anti-misoperation logic interlocking method for an energy storage power station. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above-mentioned method, so the specific limitations in the embodiments of the temporary grounding wire anti-misoperation logic interlocking device for an energy storage power station provided below can refer to the limitations of the temporary grounding wire anti-misoperation logic interlocking method for an energy storage power station above, and will not be repeated here.
