[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0028] The embodiment of the present invention discloses a method for analyzing power grid disaster emergency situations. Figure 1 As shown, the method includes the following steps:
[0029] Step 101: Obtain parameter information of disasters in a target area.
[0030] For example, the target area may be an area affected by a disaster, and the disaster parameter information may include the type of disaster that has occurred, its duration, and its severity. The embodiments of the present invention do not limit the disaster parameter information, type, or quantity, and those skilled in the art may determine the information based on actual needs.
[0031] Step 102: Analyze the first analysis result of the power equipment in the target area based on the parameter information of the disaster and a preset power equipment simulation model; the preset power equipment simulation model is constructed based on the basic operating parameters of the power equipment in the target area and the hierarchical relationship between each power equipment.
[0032] For example, the first analysis result may be the loss of power equipment in the corresponding target area based on the disaster parameter information. The loss of power equipment may include information such as whether the power supply of power equipment at all levels is normal and whether the equipment is damaged. For damaged power equipment, the damage statistics may be collected. The embodiments of the present invention do not limit the type of power equipment loss, and those skilled in the art may determine this based on actual needs. The power equipment may include power stations, substations, converter stations, transmission towers, and other power equipment within the target area. Basic operating parameters may include the range, geographic location, voltage, and the connection relationship between various facilities within the target area. The embodiments of the present invention do not limit the type and quantity of power equipment within the target area, and those skilled in the art may determine this based on actual needs. Based on the acquired parameter information of the disaster, the parameter information is input into a power equipment model that is consistent with the actual power equipment status in the target area. This allows for an immediate prediction of the damage in the target area, enabling a first-hand understanding of the disaster situation in the target area and ensuring timely repairs after the disaster.
[0033] The present invention provides a power grid disaster emergency analysis method, which includes obtaining parameter information of a disaster in a target area, and analyzing a first analysis result of the power equipment in the target area based on the disaster parameter information and a preset power equipment simulation model; the preset power equipment simulation model is constructed based on the basic operating parameters of the power equipment in the target area and the hierarchical relationship between the power equipment. By obtaining the disaster parameter information and making a preliminary assessment of the disaster situation in the affected area based on the actual disaster information and the preset power equipment simulation model, the disaster situation can be statistically analyzed in the shortest possible time, reducing the disaster response time and ensuring the optimal repair time, which has an important supporting effect on power emergency decision-making.
[0034] As an optional embodiment of the present invention, the method further includes:
[0035] Step 103: Obtain a first emergency repair measure based on the first analysis result and the repair target.
[0036] For example, the emergency repair goal can be the overall macro-goal of emergency repairs in the target area. Specifically, it can be minimizing economic losses, minimizing residential power outages, and quickly restoring power to important users. Based on the predicted losses in the target area and the emergency repair goals, corresponding emergency repair measures are generated. For example, when the emergency repair goal is set to prioritize the fastest power restoration for important users, the corresponding emergency repair measures should first be to sort out the power equipment that supplies power to important users and repair the involved power equipment based on their importance. Based on the determined emergency repair measures, the approximate time for restoration of operation at different nodes can be estimated. It can also be predicted how much power will be restored to the entire affected area after the power facilities / equipment at a certain node are repaired in the future. Ultimately, a prediction of power restoration status can be generated for the entire emergency repair process. The corresponding emergency repair measures can be determined by querying a table such as a disaster repair sequence table to determine the relevant measures. For example, when the emergency repair goal is to quickly restore power to important users, the corresponding emergency repair measure determined by consulting the table is to prioritize repairs to the infrastructure surrounding important users. The embodiment of the present invention does not limit the types and quantities of emergency repair targets and the methods of emergency repair measures, and those skilled in the art can determine them according to actual needs.
[0037] As an optional embodiment of the present invention, the method further includes:
[0038] Step 104: Obtain actual detection results of the power equipment; update the first analysis result based on the actual detection results to obtain a second analysis result; and obtain a second emergency repair measure based on the second analysis result and a repair target.
[0039] For example, the first time may be the time for immediate emergency repairs to the target area based on the parameter information of the disaster. During the first-time emergency repairs and investigations based on the first analysis results within the first time, the actual loss results in the target area can be further obtained, and the damage conditions of the corresponding power equipment and the damage conditions of the surrounding environment in the actual investigation results can be mapped one by one to the preset power equipment simulation model. In this way, the power equipment simulation model can truly and effectively reflect the actual disaster situation in the target area, and the data obtained by analysis is more convincing.
[0040] The second analysis result in the target area is obtained by mapping the power equipment simulation model of the actual investigation results, wherein the second analysis result can be the overall loss status, the calculated power supply impact, etc. The embodiment of the present invention does not limit the type of the second analysis result, and those skilled in the art can determine it according to actual needs. Based on the second analysis result, further emergency repair measures can be obtained in combination with the emergency repair target. The emergency repair measures can be to open up the power transmission channel for important users first, start emergency repairs from high-level voltage facilities, and restore the power supply capacity of the majority of people in the fastest order based on probability theory calculations. Specific emergency repair measures may include the repair order of different power facilities, when each damaged power facility can start repairs, and when the repairs are completed.
[0041] As an optional embodiment of the present invention, step 104 includes: mapping the actual detection results to the preset power equipment simulation model to obtain a first power equipment simulation model; applying a loss load to the nodes in the first power equipment simulation model based on the parameter information of the disaster to obtain a second equipment simulation model; and obtaining the second analysis result based on the parameter information of the disaster and the second power equipment simulation model.
[0042] For example, in the process of mapping the actual investigation results to the preset power equipment simulation model, different degrees of load can be applied to the nodes corresponding to the actual power equipment in the power equipment simulation model according to the damage situation. The more serious the damage, the greater the load applied. The connectivity of the power equipment can be verified based on the power equipment simulation model to verify whether the power supply of various areas in the disaster area can continue to be guaranteed in the event of a disaster. The verification method is to calculate the path from the power station node or the external entry node to the final power consumption area. If the corresponding path is the same as the actual one, the power supply is normal, otherwise it is abnormal. The disaster loss result prediction work is based on the basic parameters of different disasters, combined with the calculation of the disaster loss prediction model, and further considers the comprehensive effect of the disaster chain between different types of disasters in major disasters, to carry out research on the loss prediction algorithm.
[0043] Specifically, the following is a specific implementation of the calculation process of the disaster loss prediction model: Step A: Obtain meteorological parameter information about the disaster from official departments; Step B: Based on the disaster information, predict the probability of damage to power facilities and equipment in different locations through big data analysis, physical models, or probabilistic analysis models; Step C: Conduct secondary derivative analysis of the disaster, and further use the model from Step B to predict secondary derivative disaster losses; Step D: Finally, complete the prediction of power facility and equipment losses within the region. This embodiment of the present invention does not limit the model type and prediction method of the disaster loss prediction model, and those skilled in the art can determine it according to actual needs.
[0044] As an optional embodiment of the present invention, the process of constructing the power equipment simulation model preset in step 102 includes:
[0045] Step 201: Obtain basic operating parameters of power equipment within a target area. The basic operating parameters include the type, location, and voltage information of the power equipment. For example, the basic operating parameters of the power equipment may include the type (such as power stations, substations, converter stations, and transmission poles), location (geographic coordinates of the power equipment), and voltage information (voltage level during operation of the power equipment, which may be classified into different voltage levels) of all power equipment related to the power supply equipment within the target area.
[0046] Step 202: Construct a simulated network of power devices within the target area based on the categories and location relationships. For example, all power devices within the target area are combined to form a simulated network based on their categories and locations. This effectively reflects the layout of power devices within the target area, enhancing the authenticity of the simulated network.
[0047] Step 203: Divide the simulated network into different levels based on the voltage information. Levels with the same voltage information are considered a node. For example, different power devices operate at different voltages. The simulated network corresponding to each power device is divided into different levels based on the voltage of the power device. All power devices within a level are considered a node. Treating power devices within a level as a node allows for unified management of similar power devices, improving the processing speed of the simulated network for power devices.
[0048] Step 204: Divide the target area into different grids based on the level of the power equipment. Each grid contains only one level of power equipment, and the size of the grid is proportional to the voltage information. For example, the grid size of each level is associated with the voltage level of the level, and the area is gridded using squares or hexagons. The resulting networks have different sizes at different levels, with higher voltage levels generally having larger grid sizes. This reflects the high energy consumption of power equipment at higher voltage levels and allows for intuitive visualization of the distribution of power facilities within the simulated network of power equipment.
[0049] Step 205: Connecting the different grids based on the positional relationship of the power equipment to obtain the preset power equipment simulation model.
[0050] As an optional embodiment of the present invention, when there are at least two power transmission lines in the grid, the grid is split into at least two grids based on the positional relationship and connection relationship of the power equipment within the grid, and there is only one power transmission line in the split grids.
[0051] For example, a power transmission line is a transmission line for supplying power between power devices. Each grid includes at least one power device. When there are two or more power devices in a grid, there will be two or more power transmission lines in the corresponding grid. There are two routes in a grid. When one of the routes is damaged, it does not mean that the entire grid is unusable. Since the number of external connections of a single grid is fixed, the grid needs to be split so that there is only one line in a grid, thereby ensuring that the line in the grid can represent the entire grid. Figure 3 As shown, the left side of the figure shows a grid containing two lines, while the right side shows a grid with only one line after being split. The connection between the split grids is determined by the location of the power equipment in the grid. The embodiments of the present invention do not limit the grid splitting rules, as long as the split grids have only one line. Those skilled in the art can determine the rules based on actual needs.
[0052] As an optional embodiment of the present invention, step 102 includes: applying a loss load to a node in the preset power equipment simulation model based on parameter information of the disaster; and obtaining the first analysis result based on the power equipment simulation model after applying the loss load.
[0053] For example, when inputting disaster parameter information into the preset power equipment simulation model, varying degrees of load can be applied to nodes in the power equipment simulation model corresponding to actual power equipment based on the damage situation. The more severe the damage, the greater the applied load, and a fixed distance is added to the connection between the damaged node and surrounding nodes. A specific method can use the Dijkstra algorithm to calculate the distance between nodes. By controlling the distance of the lines, changes in power transmission capacity can be represented. Specifically, the distance between different grids during normal operation can be set to 0.01, and the distance between a damaged grid and all surrounding nodes can be set to 1000, so that the distance between damaged nodes is much greater than the distance during normal power transmission.
[0054] The embodiment of the present invention also discloses a power grid disaster emergency analysis device, such as Figure 4 As shown, the device includes:
