[0029] Embodiment 1

[0030] See also Figure 1 , shows a flow chart of a power transfer method provided by the first embodiment of the present invention, the method can be executed by a power transfer device, the power transfer device can be implemented in the form of hardware and / or software, and the power transfer device can be configured in a computer device. Figure 1 As shown, the method includes:

[0031] Step 101: determine the bus to be transferred as the target line.

[0032] In this embodiment, the busbar to be transferred (such as a 10KV line) that has a fault in the substation that has a fault and / or is connected to the busbar to be transferred is used as the target line, which can quickly identify the weak links in the power system and take measures. The busbar is an important node in the substation for collecting, distributing and transmitting electric energy. When the busbar fails, it may cause power supply interruption and affect the normal power consumption of a wide range of users. Therefore, by clarifying the target line in advance, an emergency transfer plan can be designed in a targeted manner to quickly restore power supply and avoid large-scale power outages.

[0033] The power system includes the main grid and the distribution network. The main grid collects voltage loss signals such as busbar voltage loss, main transformer voltage loss and substation voltage loss in the power system. The distribution network receives these voltage loss signals and activates the regional self-healing function to solve the power failure caused by the voltage loss signal. The distribution network correctly identifies and merges the faulty bus processing through the station-line-10kV bus relationship to avoid repeated or conflicting operations such as transferring the faulty bus to other faulty buses. When executing the transfer plan, the power system automatically obtains the connection relationship of the current target line on the single-line diagram in real time and performs topological analysis to ensure that each operation is based on the latest network status.

[0034] Step 102: When it is determined that the target line loses voltage, one or more power transfer plans are generated for the target line.

[0035] Voltage loss refers to the state where the voltage of the target line disappears or becomes abnormal, resulting in the inability to transmit power normally. This situation may be caused by a fault in the target line itself, a fault in the substation connected to the target line, or other system abnormalities. Voltage loss is a direct manifestation of power outage and needs to be resolved by timely power transfer.

[0036] The power transfer plan refers to a series of power transfer paths and execution strategies designed for the target line after the voltage loss. The goal of the power transfer plan is to transfer power from other normally operating busbars to the target line to restore power supply.

[0037] In this embodiment, when a target line fails or a substation connected to the target line fails, causing the target line to lose voltage, the power system needs to immediately formulate one or more transfer plans to restore power supply by transferring power from other normally operating busbars, ensuring that when the target line loses voltage (i.e., power outage or voltage disappears), power supply can be quickly restored to reduce power outage time and ensure the reliability of the power system. The main purpose of formulating a transfer plan is to provide multiple alternative paths so that power can be supplied through other available busbars, and to flexibly respond to different fault conditions. It can also select the optimal transfer path according to the current load status of the power system, reduce the load pressure of other lines, and avoid the expansion of faults.

[0038] Step 103: configure priorities for the target line and the transfer plan respectively.

[0039] In this embodiment, when a fault occurs in the power system or the target line loses voltage, there may be multiple situations of the target line and there may be multiple optional transfer plans. By configuring priorities for these target lines and transfer plans respectively, the optimal or most suitable target line execution order and transfer plan are quickly screened out. This method of configuring priorities helps to reasonably distribute loads in complex power systems, avoid overloads or new faults, increase the speed of power supply recovery, reduce user power outage time, and ensure power supply quality. At the same time, the setting of priorities can also reflect the execution order of different plans, so that the power system has higher stability and security when fault recovery occurs, and enhances the self-healing ability and power supply continuity of the power system.

[0040] In one embodiment of the present invention, step 103 may include the following steps:

[0041] Step 1031: Query the number of transfer plans configured for the target line.

[0042] In this embodiment, for each target line fault (such as voltage loss), the power system equips the target line with one or more power transfer plans, and restores power supply to the power users of the target line by executing the power transfer plans. The number of power transfer plans is counted to provide a basis for the priority of subsequent configuration of power transfer plans. The power transfer plan with the highest priority is selected to perform power supply maintenance for the power system users, avoid blind decision-making, and improve the efficiency and accuracy of fault power transfer, thereby providing a clear operational direction for power supply restoration and helping to ensure power supply reliability and stability.

[0043] Step 1032: Query the topological information of other busbars and substations to be transferred in the power transfer plan.

[0044] In this embodiment, when there are multiple power transfer schemes for a target line, by querying the topological information of other buses to be transferred and substations, the network structure of the substation where the other buses to be transferred are located, the association relationship between the other buses to be transferred, and the information of the main transformers to which the other buses to be transferred belong can be grasped. These relationships can provide a scientific basis for the order of executing power transfer for the target line, and improve the safety and reliability of power supply restoration.

[0045] Step 1033: Configure priorities for target lines according to quantity and topology information.

[0046] In this embodiment, the priority of the target line configuration is determined according to the number of transfer schemes and topological information in order to sort which target line is prioritized for transfer among multiple target lines, and the target line with the greatest advantage and the least impact on the power grid is preferentially selected for transfer. If the target line loses pressure over a large area, the execution priority of the target line will be increased.

[0047] For example, if the number is equal to one, the target line is configured with a priority of the first line level. When there is only one transfer scheme, the recovery path is unique. In this case, no comparison or screening is required, and the target line is directly configured with a priority of the first line level to ensure fast and efficient power supply restoration. The situation of this type of target line is often the simplest and the lowest risk, and the operation time for power system restoration is the shortest.

[0048] If the number is greater than or equal to two, and the topology information shows that the other buses to be transferred belong to the same main transformer, the target line configuration priority is the second line level; when there are multiple transfer schemes, but the other buses to be transferred in these transfer schemes are connected to the same main transformer, although the number of transfer schemes increases, the path is relatively simple and the load distribution is more direct. This type of target line configuration priority is the second line level because they have higher stability during load switching, and the main transformers share the load more evenly, and the risk is relatively low.

[0049] If the number is greater than or equal to two, and the topology information shows that the other buses to be transferred belong to different main transformers in the same substation, the target line configuration priority is the third line level; when the other buses to be transferred in multiple transfer schemes are located in the same substation, but different main transformers. This situation is relatively complicated, because the switching across the main transformer involves the load distribution of more equipment, and there is a certain risk of load shock during the operation. Therefore, the target line configuration priority is the third line level.

[0050] If the number is greater than or equal to two, and the topology information shows that the other buses to be transferred belong to different substations, the target line is configured with a priority of the fourth line level; when the other buses to be transferred in multiple transfer schemes belong to different substations, the path is the most complex, involving load switching across substations. The risk of executing transfer of such target lines is higher, because switching between different substations may introduce new fault risks or communication coordination problems, and the recovery time will also be relatively long. Therefore, the priority of such target lines is configured as the fourth line level, which is the lowest priority. The first line level is higher than the second line level, the second line level is higher than the third line level, and the third line level is higher than the fourth line level.

[0051] Step 1034: When there are multiple transfer plans for the same target line, the multiple transfer plans are prioritized according to the operating status of other buses to be transferred.

[0052] In this embodiment, in the power system, when there are multiple transfer schemes for the same target line, each transfer scheme is usually simulated and evaluated through the power system analysis software, and the operating status of different transfer schemes after implementation is predicted based on the current load distribution and power grid status, and the impact of each transfer scheme on the stability and load balance of the power system is simulated. Therefore, the operating status of the power system after the transfer of other buses to be transferred in each transfer scheme is analyzed, and the priority of the transfer scheme is configured according to the operating status, so as to select the most appropriate transfer scheme to perform the transfer operation on the target line, thereby ensuring the stable operation of the power system.

[0053] Exemplarily, the operating status of other buses to be transferred in is queried, and the operating status includes the first load rate of the main transformer after the transfer of other buses and the second load rate after the transfer of other buses; it can ensure that the load of each substation and bus is kept within a reasonable range after the transfer of other buses, avoiding equipment failure or grid instability due to excessive load. Sort multiple transfer schemes from small to large according to the first load rate to obtain a scheme sequence; if the first load rates corresponding to multiple transfer schemes are different, the priority of multiple transfer schemes is configured according to the scheme sequence; if the first load rates corresponding to multiple transfer schemes are the same, the transfer schemes with the same first load rate are sorted from small to large according to the second load rate to update the scheme sequence; the priority of multiple transfer schemes is configured according to the updated scheme sequence. Through scientific and reasonable scheme sorting, all target lines and loads are transferred out to the maximum extent, and the line cannot be transferred due to the overload of the main transformer transferred in is reduced, so that the power system can realize efficient and stable redistribution of electricity to the power users on the target line, ensure that the power supply is not interrupted during fault handling, and reduce the impact on power users.

[0054] Step 104: Perform safety verification on the target line and the power transfer plan.

[0055] In this embodiment, in the power system, the transfer operation involves the redistribution of electric energy between the target line and other buses. If the operation is not strictly verified, it may lead to new safety hazards, such as overload, short circuit or voltage fluctuation. Therefore, by performing a safety check on the target line and the transfer scheme in a closed loop, the safety and feasibility of the transfer scheme under the current power system are confirmed.

[0056] Step 1041: Verify the first state of the target line executing the power transfer plan.

[0057] In this embodiment, the first state of the target line executing the power transfer scheme is verified to ensure the safety and feasibility of the power transfer operation and to prevent the power system from generating new risks due to misoperation.

[0058] Exemplarily, the power system queries the position status of the switch to be transferred out in the target line to ensure that the switch to be transferred out is in the open position to avoid malfunction caused by telemetry and telesignal mismatch. If the switch is in the open state, the operating status of other buses to be transferred in is further analyzed, and the operating status includes the first load rate of the main transformer after the other buses are transferred in and the second load rate after the other buses are transferred in. This is because in the power system, if the load of the transferred bus is too high, it will cause overload, tripping and other problems, and the switch in the open state means that the target line is in a power-off state, and it is necessary to conduct a safety assessment of the transfer plan to ensure that other buses will not exceed the load threshold after the transfer. When the first load rate and the second load rate are both less than or equal to the preset load threshold, the power system will determine that the first state is safe. If the first load rate and the second load rate exceed the load threshold (i.e., 100% (the percentage is configurable)), it will not be automatically executed to avoid the automatic transfer of the power system causing the opposite line and the main transformer to overload.

[0059] Step 1042: Verify the second state of the self-healing function of the target line.

[0060] In this embodiment, the second state of the self-healing function of the target line is verified to verify whether the self-healing mechanism of the power system is in a non-locked state, so as to ensure that the power system can quickly recover and adjust after a fault. The self-healing mechanism is an important feature in the power system, which can automatically take measures after fault detection, such as cutting off the faulty line or transferring power supply. However, when the self-healing function is in a locked state, the system cannot automatically adjust or recover, and the execution of the power transfer operation will lack the necessary safety guarantees. Therefore, by verifying the state of the self-healing function, the power system can confirm whether the target line has the ability to self-heal from faults, thereby ensuring that the power transfer plan is smoothly executed under the premise of safety.

[0061] When the stability control device of a plant in the power system is activated, or the low-frequency and low-voltage load reduction device is activated, the power system will automatically lock the self-healing mechanism of the area and wait until the relevant abnormal signals return to normal. This is to avoid the self-healing function from operating incorrectly when the power system is unstable, thereby violating the requirements of power safety and stability control and further exacerbating the instability of the system.

[0062] Step 1043: If the first state is safe and the second state is a non-locked state, it is determined that the safety check has passed.

[0063] In this embodiment, the safety of the first state ensures that the other busbars to be transferred will not be overloaded due to the transfer operation, while the non-locking state of the second state ensures that the power system has the ability to self-heal and recover from faults. When both states are met at the same time, the power system will determine that the transfer plan has passed the safety check and thus execute the transfer operation. This safety check is to verify the operational safety and recoverability of the power system from multiple angles, to ensure that the transfer plan can be implemented efficiently without causing secondary risks, and to maximize the stability of power supply and the continuous safe operation of the power system.

[0064] Step 105: If the safety check is passed, each power transfer plan is executed in sequence according to the priority to transfer to other buses and supply power to the power users in the target line.

[0065] In this embodiment, when a target line in the power system fails or loses voltage, in order to quickly restore power supply to users, the power system will perform a safety check on the alternative power transfer schemes. After passing the check, these power transfer schemes are executed in sequence according to the pre-set priority order, and the load of the target line is transferred to other normally operating buses to ensure that the scope of the fault impact is minimized and the power supply to users can be restored as soon as possible.

[0066] Specifically, the operation information of other buses to be transferred to is queried in each transfer scheme. By comparing the actual operation information with the preset transfer conditions, it is possible to determine whether these other buses to be transferred to meet the basic requirements for transfer. The transfer conditions usually involve at least one of the remote control state of the switch, the transfer range, and the load rate, etc., to ensure that the power transfer process does not cause equipment overload or power system instability, and ensure the safety of the power supply plan.

[0067] If the operating information meets the conditions for power transfer, the power transfer plan is executed in order of priority and the importance of the target line power users (such as power supply guarantee users, important users, general users, etc.) is arranged in descending order from left to right to transfer to other buses and supply power to the power users in the target line. The priority setting ensures that the most appropriate power transfer plan is executed first, thereby improving power supply efficiency and restoring power supply to the target line in the shortest time, minimizing power outage time. When executing the power transfer plan, the power system automatically obtains the connection relationship of the current target line on the single-line diagram in real time and performs topological analysis to ensure that each operation is based on the latest network status.

[0068] If the operating information does not meet the transfer conditions, the power system will execute the transfer plan in order of priority and arrange the power users of the target line according to the importance of the power users in the target line, and generate a transfer strategy for the transfer plan according to the execution result of transferring to other buses and supplying power to the power users in the target line, and calculate the transferable routes of the remaining target lines to be transferred out, so as to avoid forced transfer at inappropriate times or conditions and avoid unnecessary risks. When the confirmation operation of the transfer strategy is received, the transfer operation is officially executed to ensure that all target lines reach a consensus on the transfer strategy, avoid operational errors or mistakes, and ensure that the transfer process is carried out as planned, so as to transfer to other buses and supply power to the power users in the target line.

[0069] In this embodiment, the power system is integrated with multiple systems such as the existing monitoring and data acquisition system (SCADA), automation equipment, and stabilization control system to ensure the stability of power transfer and improve the coordination between bus data. The present invention realizes automatic perception of the target line, verifies the real-time topology of the power system, automatically generates a power transfer plan, and orderly executes the transfer remote control of other buses to be transferred through the coordinated regional self-healing closed-loop function of the main power grid and the distribution network in the power system, efficiently restores the load affected by the pressure-losing bus, supports emergency disposal of large-scale power outages, and resolves the benchmark and basic risks of the power grid. The stations with more than 30,000 users that may cause large-scale power outages in counties / towns are put into self-healing closed-loop operation to solve the benchmark risk of a single substation pressure loss level 3 event (or a large-scale power outage in counties and towns); according to the level 3 and above basic risk and real-time risk, the corresponding stations are put into self-healing closed-loop operation to achieve downgrade based on problem risk and real-time risk of the power grid.

[0070] In an embodiment of the present invention, a busbar to be transferred out is determined as a target line. A fault occurs in the target line and / or a substation connected to the target line fails. When it is determined that the target line loses pressure, one or more transfer plans are generated for the target line, and priorities are respectively configured for the target line and the transfer plan. A safety check is performed on the target line and the transfer plan. If the safety check is passed, each transfer plan is executed in sequence according to the priority to transfer to other busbars and supply power to the power users in the target line. By accurately identifying the target line fault and generating multiple transfer plans, the power system can quickly provide a variety of emergency power supply options when the target line loses pressure. By configuring the priority of the transfer plan and performing a safety check, the efficiency and safety of the transfer operation are ensured, and secondary faults caused by overload or operational errors are avoided. The transfer plan is executed according to the priority to ensure the speed and reliability of the power system to restore power supply, thereby minimizing the power outage time and improving the stability of the power system.
