[0056] Reference Figure 1 As shown, in one embodiment of the present disclosure, a method for assessing power outage risk of a main power distribution system is provided, comprising:

[0057] S101, constructing a power grid topology structure;

[0058] The grid topology is constructed in advance for the main distribution network. The generated grid topology can be used to identify the topology of the power system, that is, to identify the connection relationship between the nodes in the power system and establish a topological structure model of the power system. The network structure of the power system can be accurately understood, including the substations, feeders, distribution lines and other components on the high-voltage and low-voltage sides, thereby providing basic data for the automated operation and management of the power system.

[0059] In a specific example, step S101 includes:

[0060] Obtaining the connection mode between internal elements and nodes in the main distribution network;

[0061] Among them, the internal components and node connection methods can belong to the distribution network or the main grid.

[0062] A power grid topology structure is constructed according to the connection mode between the internal elements and the nodes, wherein the connection mode is a wiring mode.

[0063] Specifically, the constructed power grid topology structure can be used to make timely judgments when a power outage risk occurs.

[0064] S102, searching the power grid topology structure to determine the power outage equipment and power outage range in the main distribution network;

[0065] Specifically, the power outage scope includes power plants, transformers, lines, line sections and users, etc. This allows statistics on the loss of load when a power outage occurs, and can also be used for power outage scope inspection before operation, maintenance planning and after a fault occurs.

[0066] S103, performing topology identification according to the power grid topology structure to obtain devices with power supply risks;

[0067] Specifically, the generated power grid topology structure can be used to identify the topology of the power system, that is, to identify the connection relationship between each node in the power system and establish a topological structure model of the power system. The network structure of the power system can be accurately understood, including various components such as substations, feeders, and distribution lines on the high-voltage and low-voltage sides, thereby providing basic data for the automated operation and management of the power system. According to the real-time topology of the power grid, the special operation mode of the power grid, including the main network and distribution network equipment, is identified, and the plants and equipment with power supply risks are automatically analyzed and checked to realize the operation risk monitoring of the main distribution network.

[0068] S104, generating a corresponding new wiring mode according to the power outage device;

[0069] Reference Figure 2 As shown, in a specific example, S201, pre-calculate the preset wiring mode of the main distribution network when the expected device is disconnected;

[0070] The calculation method for the main distribution network wiring method under the expected equipment disconnection can be determined in advance.

[0071] S202, when a power outage occurs, determining the power outage device;

[0072] After a power outage occurs, the wiring method of the power grid can be automatically triggered and calculated to generate a new wiring method reminder after the power outage device is identified.

[0073] S203: Calculate the corresponding new wiring mode for the power-off device based on the preset wiring mode.

[0074] After the automatic calculation equipment is powered off, the wiring mode of the power grid can automatically trigger the calculation. Among them, the new wiring mode can also include a weak wiring mode. Optionally, the calculation of the weak wiring mode of the main distribution network under the expected equipment disconnection can be automatically calculated. After the equipment is powered off, the wiring mode of the power grid can automatically trigger the calculation and generate a new weak wiring mode reminder.

[0075] S105, determining the affected load corresponding to the power outage equipment according to the power outage equipment and the power outage range, and generating a power transfer strategy for the affected load;

[0076] Among them, the transfer strategy includes the transfer path, transfer capacity, etc. When a power outage occurs in the main and distribution networks, the affected loads are analyzed according to the target equipment, and the affected loads are safely transferred to the new power source. A load transfer operation plan including the transfer path and transfer capacity is proposed to reduce the impact on the power outage area and users.

[0077] S106, generating a load control strategy according to the main distribution network dispatching model and the new wiring mode;

[0078] Among them, the main distribution network dispatching model can be determined according to the grid topology corresponding to the main network and the distribution network. Combined with the main distribution network dispatching model, when a power outage occurs in the power grid, multiple load supply area adjustment strategies will be generated according to the new wiring method, provided to the dispatcher process for selection, and the optimal path can be finally determined to reduce the impact of the power outage area and users, and help the power grid restore power supply.

[0079] S107, generating a new power grid topology according to the new wiring mode, the power transfer strategy and the load control strategy; and

[0080] Specifically, when a power outage occurs in the power grid, a corresponding new power grid topology is generated based on the new adjustment strategy. The system will automatically calculate the execution risk of the existing maintenance method under the new connection method based on the new equipment topology connection method, and remind the dispatcher to take precautions.

[0081] S108, generating current power grid risk warning information according to the new power grid topology and the equipment with power supply risk.

[0082] Specifically, the connection relationship between the current nodes can be evaluated according to the current new power grid topology, and early warning reminders of the current power grid risk warning information can be generated for devices with power supply risks, so as to promptly remind users and managers.

[0083] In this embodiment, the devices in the power grid that are at risk of power supply due to the power outage are analyzed based on the topological structure of the power grid, and then a new wiring mode is calculated, and corresponding load transfer strategy and load control strategy are made to help restore power supply faster. The new power grid topology generated by the new adjustment strategy is analyzed and evaluated to generate the final current power grid risk warning information.

[0084] In a specific example, it also includes:

[0085] Analyze the maintenance method according to the main distribution network dispatching model and the power grid section;

[0086] Evaluate the risk information of the power grid after maintenance according to the maintenance method;

[0087] Specifically, the grid risk after the maintenance operation is performed is evaluated, and grid risk information is obtained, such as automatically publishing or pushing analysis result information such as power outage users, power outage operations, risky equipment, and risk warning notices.

[0088] The power grid risk information is pushed to the user end.

[0089] The maintenance assessment structure can then be pushed to the user end in a timely manner. For temporary maintenance, it supports the control personnel to manually set the maintenance equipment, automatically analyze the post-maintenance method to adjust the suggestions and evaluate the grid risk level and risk prevention measures, so as to realize automatic adjustment and evaluation of the maintenance method.

[0090] In a specific example, it also includes:

[0091] Determine the power outage situation of the user according to the power outage equipment of the main distribution network and the power outage scope;

[0092] After obtaining the power outage equipment and power outage range of the main distribution network, the calculation of power outage for important users under the expected equipment disconnection of the main distribution network can automatically trigger the possibility of power outage for important users after the equipment is powered off, that is, the power outage situation of the above-mentioned users.

[0093] A target user is determined according to the power outage situation of the user, and a power outage reminder is generated for the target user.

[0094] Specifically, when an important user in the main distribution network is at risk of power outage, an alarm can be generated to remind the user in a variety of ways, such as text messages, phone calls, etc., to avoid losses caused by power outages.
