[0025] Embodiment One

[0026] Figure 1a is a flow chart of a power restoration method based on a power distribution network provided by Embodiment One of the present application. The present embodiment can be applied to the case of displaying the information of the substation equipment when the substation is under maintenance. The method of the present embodiment can be executed by a power restoration device based on a power distribution network, which can be realized by software and / or hardware, and can be configured in a server or a terminal device.

[0027] Accordingly, the method specifically includes the following steps:

[0028] S110. In response to detecting that the target power supply equipment in the power distribution network is in a power outage state, acquire at least one first switching device that matches the target power supply equipment and is in a turned-off state.

[0029] In this context, a distribution network refers to a power grid that receives electrical energy from the transmission network or regional power plants and distributes it locally or tiered according to voltage to various users through distribution facilities. A distribution network consists of overhead lines, cables, poles, distribution transformers, disconnect switches, reactive power compensators, and some auxiliary facilities, playing a crucial role in distributing electrical energy within the power grid. Power supply backup equipment refers to equipment that requires higher reliability in the distribution network. A shutdown state means that the switching device is in a closed or open state, unable to provide normal power supply. The primary switching device can be a tie switch and / or a disconnector, capable of directly closing or opening other backup power supply paths for the power supply backup equipment.

[0030] For example, such as Figure 1b As shown, when the power supply equipment (i.e., distribution transformer z) is in normal power supply condition, it is powered by power source C. When power source C fails to supply power due to an abnormal reason, i.e., distribution transformer z is in a power outage state, it needs to be replaced by other power sources (i.e., power source A, power source B, or power source D) to restore power supply. Since power source C supplies power to distribution transformer z under normal power supply condition, all switching devices on the connection line between power source C and distribution transformer z, i.e., switching devices C1 and C2, must be in the conducting state. However, power sources A, B, and D do not supply power to distribution transformer z. Obviously, at least one switching device in the connection line between power sources A, B, and D and distribution transformer z is in the off state. Therefore, to obtain the switching device (i.e., the first switching device) that is directly or indirectly connected to the target power supply equipment and is in the off state, we need to obtain one switching device in the connection line between the target power supply equipment and power sources A, B, and D that is in the off state.

[0031] Optionally, before setting the target first switching device corresponding to the target power transmission path to the conducting state and supplying power to the target power supply equipment through the target power transmission path, the method further includes setting at least one second switching device in the original power transmission path that was in the conducting state before the target power supply equipment was de-energized to the off state.

[0032] The original power transmission path is the path that supplies power to the backup power supply equipment before the power outage, i.e., under normal power supply conditions. The second switching device is the switching device on the original power supply path, which can be a tie switch and / or a disconnector, etc., that can directly close or open the original power supply path of the backup power supply equipment.

[0033] As shown in the preceding example, before the target power supply equipment is powered off, the original power transmission path is the power transmission path between the power source C and the distribution transformer z, and at least one second switch device in the original power transmission path in an on state is set to an off state. Specifically, the second switch device C3 can be set to an off state.

[0034] The advantage of this arrangement is that by setting at least one second switch device in the original power transmission path in an on state to an off state, the phenomenon of the target power supply equipment being subjected to a power supply load when the original power source suddenly resumes power supply can be avoided, power supply to the power supply equipment can be more secure, and oscillation of the target power supply equipment can be avoided, and the power supply of the power supply equipment can be affected.

[0035] Optionally, the at least one second switch device in the original power transmission path in an on state before the target power supply equipment is powered off is set to an off state, including: obtaining an overlapping path, a first non-overlapping path, and a second non-overlapping path between the original power transmission path and the target power transmission path; the first non-overlapping path is in the original power transmission path, and the second non-overlapping path is in the target power transmission path; obtaining an intersection point between the first non-overlapping path and the second non-overlapping path, and obtaining a target second switch device closest to the intersection point and in an on state in the first non-overlapping path; and setting the target second switch device to an off state.

[0036] The overlapping path can be a repeated path between the original power transmission path and the target power transmission path when the power supply equipment is powered. The first non-overlapping path can be a path obtained by removing the overlapping path from the original power transmission path. The second non-overlapping path can be a path obtained by removing the overlapping path from the target power transmission path.

[0037] As shown in the preceding example, Figure 1c the overlapping path is the power transmission path between the node n and the distribution transformer z, the first non-overlapping path is the power transmission path between the power source C and the node n, and the second non-overlapping path is the power transmission path between the power source D and the node n.

[0038] Further, the intersection point between the first non-overlapping path and the second non-overlapping path is obtained, and the intersection point is the node n. In the first non-overlapping path, that is, the power transmission path between the power source C and the node n, a target second switch device closest to the intersection point n and in an on state is obtained, and the second switch device can be C3. The target second switch device C3 is set to an off state.

[0039] The advantage of the arrangement is that by determining the overlapping path, the first non-overlapping path and the second non-overlapping path, and obtaining the target second switch device closest to the intersection point and in the on state in the first non-overlapping path and setting it to the off state, the switch in the overlapping path can be avoided to be set to the off state, so that the standby power supply cannot supply power. Compared with sequentially setting each second switch device as the target second switch device, and then performing the open circuit test on the original power transmission path after the setting and the pass test on the target power transmission path after the setting, the efficiency of obtaining the target second switch device is greatly improved.

[0040] S120, obtaining a target power transmission path of the target power supply device according to the first power transmission path between at least one of the first switch devices and the target power supply device, and the second power transmission path between at least one of the first switch devices and each power supply.

[0041] The first power transmission path is specifically the power transmission path between the first switch device and the target power supply device. The second power transmission path is specifically the power transmission path between the first switch device and each power supply. The target power transmission path can be the power transmission path between the target power supply device and each power supply, and the target power transmission path can be determined by the first power transmission path and the second power transmission path.

[0042] In the previous example, the first switch device can select AC, BC or CD, and the first power transmission path between the first switch device AC, BC or CD and the target power supply device and the transformer z can be obtained respectively.

[0043] Further, the second power transmission path between the first switch device AC, BC or CD and each power supply can be obtained respectively. Specifically, the second power transmission path between the first switch device AC and the power supply A can be obtained; the second power transmission path between the first switch device BC and the power supply B can be obtained; and the second power transmission path between the first switch device CD and the power supply D can be obtained.

[0044] Correspondingly, the target power transmission path is determined according to the first power transmission path and the second power transmission path. Specifically, the target power transmission path 1 from the power supply A to the transformer z; the target power transmission path 2 from the power supply B to the transformer z; and the target power transmission path 3 from the power supply D to the transformer z.

[0045] Compared with taking the target power supply protection device as a starting point to find the power transmission path to each power supply, or taking each power supply as a starting point to find the power transmission path to the target power supply protection device, the above technical solution usually needs multiple attempts to obtain the target power transmission path, and the power recovery efficiency is relatively slow. By taking the first switch device as a starting point, the first power transmission path between the target power supply protection device and the distribution transformer z, and the second power transmission path between each power supply, the corresponding target power transmission path is obtained according to the first power transmission path and the second power transmission path corresponding to a first switch device. Specifically, the power supply path of each first switch device to the target power supply protection device and each power supply is unique. In this way, the power recovery efficiency of the power distribution network can be improved. S130, set the target first switch device corresponding to the target power transmission path to an on state, and supply power to the target power supply protection device through the target power transmission path.

[0046] Wherein, the on state can be the state when the valve presents low resistance.

[0047] According to the target power transmission path 1 from the power supply A to the distribution transformer z, the target power transmission path 2 from the power supply B to the distribution transformer z, and the target power transmission path 3 from the power supply D to the distribution transformer z, an optimal path is selected, which is assumed to be the target power transmission path 3. Then set the target first switch device CD corresponding to the target power transmission path 3 to an on state, and supply power to the target power supply protection device through the target power transmission path 3.

[0048] The technical solution provided by the embodiment of the application, in response to detecting that the target power supply protection device in the power distribution network is in a power-off state, at least one first switch device matched with the target power supply protection device and in an off state is obtained; the target power transmission path of the target power supply protection device is obtained according to the first power transmission path between it and the target power supply protection device, and the second power transmission path between it and each power supply; set the target first switch device corresponding thereto to an on state, and supply power to the target power supply protection device through the target power transmission path. The problem that the power distribution network automation master station cannot effectively isolate and power on the power supply protection user when facing large-area power failure of the main network is solved, the power distribution network quickly restores power supply to the power supply protection user, which provides protection for the safe operation of the power distribution network and improves the reliability of power supply to the power supply protection user.

[0049] Optionally, the method further comprises: in response to obtaining the power supply guarantee task information, obtaining power supply configuration parameters and power supply time parameters according to the power supply guarantee task information; wherein the power supply configuration parameters include at least one of substation name, power transmission line name and power supply guarantee organization name, and the time parameters include power supply guarantee start time and / or power supply guarantee end time; comparing the power supply configuration parameters with local account data to determine whether there is a power supply guarantee device in the local account data that matches the power supply configuration parameters; if it is determined that there is a power supply guarantee device in the local account data that matches the power supply configuration parameters, setting the power supply guarantee time of the power supply guarantee device according to the power supply time parameters; and if it is determined that there is no power supply guarantee device in the local account data that matches the power supply configuration parameters, sending an error prompt to the sender of the power supply guarantee task information.

[0050] The power supply guarantee task information can be task information describing the target power supply guarantee device and the power supply guarantee device. The power supply configuration parameters can be related parameters of the power supply guarantee device, and can include parameters such as substation name, power transmission line name and power supply guarantee organization name. The power supply time parameters can be the start and end times of the power supply guarantee of the power supply guarantee device. The local account data can be data information stored in the power distribution network for counting the power distribution network.

[0051] For example, according to the obtained power supply guarantee task information, the substation name, the power transmission line name and the power supply guarantee organization name can be obtained, and the power supply guarantee start time and the power supply guarantee end time can also be obtained. The power supply configuration parameters are compared with the local account data to determine whether there is a power supply guarantee device in the local account data that matches the power supply configuration parameters.

[0052] After comparison, the matching results shown in Table 1 can be obtained, and it can be determined that there is a power supply guarantee device that matches the power supply configuration parameters of the substation name "AA substation", the power transmission line name "aa line 514" and the power supply guarantee organization name "Aa", and the matching of the substation "123". Further, according to the power supply time parameters, the power supply guarantee time of the power supply guarantee device is set, and the power supply guarantee start time is "2021-3-4 8:30" and the power supply guarantee end time is "2021-3-15 08:30".

[0053] Table 1

[0054]

[0055] Since it is determined that there is no power supply guaranteeing equipment matching the power supply configuration parameter and the substation name being "BB substation" and the transmission line name can be "bb line 510", and the matching result is inconsistent. Further, an error prompt is sent to the sender of the power supply guaranteeing task information.

[0056] The advantage of such a setting is that by obtaining the power supply guaranteeing task information and matching the parsed information with the local account data, the relevant processing operation is obtained according to the matching result. This can make the power supply process for the target power supply guaranteeing equipment more rigorous, thereby improving the accuracy, efficiency and reliability of power supply, and further realizing the rapid restoration of power supply for the power distribution network to the power supply guaranteeing user.

[0057] Embodiment Two

[0058] Figure 2 The flowchart of another power distribution network-based power restoration method provided by Embodiment Two of the present application is provided. This embodiment is refined based on the above-mentioned embodiments. In this embodiment, the target power transmission path of the target power supply guaranteeing equipment is further refined according to the first power transmission path between at least one first switching device and the target power supply guaranteeing equipment, and the second power transmission path between at least one first switching device and each power supply source.

[0059] Correspondingly, the method specifically comprises the following steps:

[0060] S210, in response to detecting that the target power supply guaranteeing equipment in the power distribution network is in a power-off state, obtaining at least one first switching device that matches the target power supply guaranteeing equipment and is in an off state.

[0061] S220, obtaining a plurality of available power transmission paths of the target power supply guaranteeing equipment according to the first power transmission path between at least one first switching device and the target power supply guaranteeing equipment, and the second power transmission path between at least one first switching device and each power supply source.

[0062] Among them, the available power transmission path can be a path that can transmit power to the target power supply guaranteeing equipment.

[0063] S230, taking the available power transmission path with the shortest transmission distance in each of the available power transmission paths as the target power transmission path.

[0064] As shown in the example, Figure 1b As shown in the example, the topology can be extended to both sides from the position of the first switching device according to the first switching device. The power supply, real-time current data and path length on both sides of each contact device can be obtained. Assuming that the power supply current on both sides of a certain first switching device is I and the path length is L. Specifically, the power supplies on both sides of the AC switch are power supply A (I A= 50A; L A至AC = 15km) and power supply C (I C = 150A; L A至AC = 15km), and the BC switch is the power supply B (I B = 150A; L B至BC = 10km) and power supply C (I C = 150A; L B至BC = 10km), and the CD switch is the power supply C (I C = 150A; L C至CD = 5km) and power supply D (I D = 150A, L C至CD = 5km). The length of the available power transmission path can be calculated according to the associated contact card.

[0065] Suppose that multiple available power transmission paths are obtained, which are: target power transmission path 1 from power supply A to distribution transformer z, target power transmission path 2 from power supply B to distribution transformer z, and target power transmission path 3 from power supply D to distribution transformer z. Assuming that the available power transmission path of the target power transmission path 3 is the shortest, the target power transmission path is the target power transmission path 3.

[0066] The advantage of such an arrangement is that when multiple available power transmission paths are determined, the power transmission path with the shortest transmission distance is selected as the target power transmission path. In this way, a more suitable available power transmission path can be selected, ensuring the efficiency of power supply to the power supply equipment and reducing the loss in the power transmission process.

[0067] Alternatively, the available power transmission path with the shortest transmission distance among the available power transmission paths is selected as the target power transmission path, which includes: if there are multiple available power transmission paths with the shortest transmission distance, the available power transmission path with the lowest load rate among the available power transmission paths with the shortest transmission distance is selected as the target power transmission path.

[0068] The load rate can be the ratio of the actual load of the transformer associated with the power transmission path to its capacity, which is used to reflect the carrying capacity of the transformer.

[0069] For example, assume that the line power current between distribution transformer z and the first switch device is I1, the line power current between the first switch device and each power supply is I2, I3, etc., and the current limiting value corresponding to each power supply is I 2限 , I 3限 ... (assuming that the current limiting value is a fixed data set, as the line length and model are different, the current limiting value is different). Then assume that the load rate of the line between the first switch device and each power supply after the power supply is f, then f = (I1 + I2) / I 2限 * 100%, f = (I1 + I3) / I 3限*100%, take the minimum load rate.

[0070] Assume that both target transmission path 1 and target transmission path 3 have the shortest available transmission paths. We need to obtain the load rates of target transmission path 1 and target transmission path 3 respectively. Assume the load rate of target transmission path 1 is 70% and the load rate of target transmission path 3 is 20%. It can be determined that the load rate of target transmission path 3 is lower, therefore, target transmission path 3 is selected.

[0071] The advantage of this setup is that when determining the available transmission path with multiple shortest transmission distances, it is necessary to consider the load rate corresponding to each of the multiple available transmission paths. This allows for the selection of a more suitable and accurate available transmission path, ensuring the efficiency of power supply to the power supply equipment and improving the reliability of power supply.

[0072] Optionally, after acquiring at least one first switching device that matches the target power supply equipment and is in a turned-off state, the method further includes: if it is determined that the target power supply equipment does not have an available power transmission path based on the first power transmission path between the at least one first switching device and the target power supply equipment, and the second power transmission path between the at least one first switching device and each power supply, then a prompt indicating that there is no available power transmission path is issued through the host computer.

[0073] In this context, the host computer can refer to the computer that directly issues control commands.

[0074] Specifically, if the target power supply equipment does not have any available power transmission path, the host computer needs to issue a prompt that no power transmission path is available and provide feedback to the relevant personnel.

[0075] The advantage of this setup is that relevant information can be promptly fed back to staff via the host computer, allowing staff to receive feedback more intuitively, ensuring the efficiency of power supply to the power supply equipment, and improving the reliability of power supply.

[0076] S240. Set the target first switch device corresponding to the target power transmission path to the conducting state, and supply power to the target power supply equipment through the target power transmission path.

[0077] The technical scheme provided by the embodiment of the present application can select a more suitable and accurate available power transmission path, ensure the power supply efficiency of the power supply device, improve the power supply reliability, and provide a guarantee for the safe operation of the power distribution network.
