[0002] With the continuous expansion of my country's power grid and the centralized access of large-scale clean energy, power grid operation and dispatching control have become data-intensive. As the core support system for power grid operation control and dispatching production management, the dispatching control system is the center for the aggregation and processing of various power grid data. For a long time, the dispatching control system has provided power dispatching staff with power grid wiring diagrams such as plant wiring diagrams and grid structure diagrams, which facilitate dispatching staff to perceive the power grid situation in real time and accurately, accurately obtain key information on power grid operation, and issue control instructions in a timely manner. Among them, the grid structure diagram is formed by the interconnection of plant wiring diagrams, which is mainly used to display the connection status of various power grid plants and lines. Generally, the first draft is drawn through the dispatching control system editing software, and then the maintenance personnel of the dispatching control system perform wiring maintenance regularly or periodically.

[0003] With the development of the control cloud construction, the control cloud has now gathered a huge amount of real-time, historical and model data, which can provide multi-dimensional data resources for control personnel. However, the existing technology does not combine GIS information to automatically generate power grid diagrams, resulting in high complexity in graphic maintenance for operation and maintenance personnel; at the same time, the grid diagram and geographic related display information are not combined, the hot spot information in the grid is not prominent, and the complexity of control personnel's monitoring is still high.

[0015] The method of distributing all plant station coordinates to adjacent grid points according to the grid unit size further includes:

[0016] All plant station coordinate points on the plane coordinates are traversed one by one, and they are fitted to the nearest grid point; when the distance is less than 50% of the grid size, they are automatically pasted to the adjacent grid; if two or more plant station coordinates are close to the same grid coordinates at the same time, the plant station coordinates at a farther distance are offset to the adjacent grid point coordinates; a two-dimensional space matrix is ​​generated to record the plant stations at each point; if the number of overlapping plant stations in some areas of the space matrix is ​​less than the threshold, the overlapping plant stations are translated one grid to the grid point with the largest free space among the surrounding 8 grid points.

[0017] The predefined mobile strategy further includes:

[0018] Priority is given to moving the 220kV plant terminal in the line; priority is given to moving the plant terminal with fewer outgoing lines, and the number of moving steps of the plant terminal is less than the maximum moving step number m.

[0019] The step of reducing the lines exceeding the critical adjustment parameters further includes:

[0020] The critical adjustment parameter n and the number of reduction layers r of the long line are configured so that the number of grids crossed by the longest line does not exceed the number of reduction layers r, where the number of reduction layers r ≦ the critical adjustment parameter n.

[0035] In order to make the purpose, technical solution and advantages of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] The embodiments described in this application are only some embodiments of the present invention, not all embodiments. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the protection scope of the present invention.

[0037] See also Figure 1 , This embodiment is a display system for provincial power grid grid mapping based on integrated hot spot information, whose data source mainly comes from the control cloud, and the system includes a data processing module and an auxiliary monitoring module.

[0038] The data processing module is used to implement two modules: data acquisition and data analysis. The data acquisition module includes obtaining various data information, the relationship between lines and plants, equipment data information, fault maintenance information, geographic coordinate information of lines and plants, and geographic coordinate related information such as weather, fault location, and personnel location from the control cloud. The data analysis module includes associating model data, GIS information, meteorological data, maintenance information, etc. based on a large amount of real-time data, historical data and model data resources from the control cloud to provide data support for graphics generation and hotspot judgment.

[0039] The auxiliary monitoring module is used to implement two modules: optimization mapping and fusion display. Among them, the optimization mapping module automatically generates a provincial grid map by combining plants, lines and geographic information through data acquisition and analysis, and optimizes the distribution based on the provincial power grid grid mapping method that integrates hotspot information. The fusion display module provides control personnel with automatic scaling, color change, labeling and other highlighting functions for plant and line elements based on power level, hotspot information, geographic related information, etc., which facilitates control personnel to capture important information in the monitoring screen and improve monitoring efficiency.

[0040] The present invention proposes a provincial power grid network diagram optimization drawing method integrating hot spot information, comprising the following steps:

[0041] Step 1: Obtain the plant station coordinates from the GIS information, obtain the relationship between the line and the plant station from the model data, generate the line length according to the relationship, and determine the grid unit size of the grid diagram according to the plant station coordinates at both ends of the minimum line length.

[0042] First, the geographical coordinates of the plant and station are obtained from the GIS information, and the relationship between the line and the plant and station is obtained from the model data. The first simplification is performed, that is, the line coordinates are replaced by the geographical coordinates of the associated first and last plants and stations to generate the line length.

[0043] Take the plant station coordinates at both ends of the minimum line length, and use the maximum value of the X / Y axis difference of the plant station coordinates as the initial unit size of the grid diagram. The minimum unit of the grid has a significant impact on the compactness of the entire diagram, so this grid size is determined as an adjustable variable, and this variable affects the size of the final generated grid diagram. The grid unit size is determined by the larger value of the X / Y axis in the minimum plant station spacing distance of the scale, see Figure 2 This ensures that the power plant with the shortest distance can still clearly display enough information, while preventing a small number of adjacent power plants from affecting the overall size. The integrated display module supports power plant and line graphics to support setting the display size according to the voltage level, such as 500kV power plant is displayed 1.5 times larger, and 500KV lines at both ends are displayed in bold.

[0044] Step 2: Distribute all plant station coordinates to adjacent grid points according to the grid unit size, adjust the grid unit size according to the distribution result, and when crossing lines appear, move the corresponding plant station endpoint according to the predefined movement strategy.

[0045] The power plants are discretely distributed on the grid points according to the principle of coordinate proximity, that is, all the power plant coordinate points on the plane coordinates are traversed one by one, and they are fitted to the nearest grid points. The distance between the adjacent coordinate points of the substation Si (Xi, Yi) is calculated, and when the distance is less than 50% of the grid size, it is automatically pasted to the adjacent grid. If two or more power plant coordinates are close to the same grid coordinates at the same time, the power plant coordinates at a distance are offset to the coordinates of the adjacent grid points. At the same time, a two-dimensional space matrix is ​​generated to record the power plants at each point. If the number of overlapping power plant sites in certain areas of the space matrix is ​​less than the threshold, the overlapping power plant is shifted one grid to the grid point with the largest free space among the surrounding 8 grid points (that is, the four points above, below, left and right of the grid have the lowest occupancy rate). If the number of overlapping power plant sites in certain areas of the space matrix reaches a certain number, the grid unit size of the entire map is reduced by half. Figure 2 After the grid is discretely distributed, the station location is moved to the adjacent grid point location, generating Figure 3 .

[0046] There are certain crossing lines in the generated graph, and the line crossing points of 500kV plants are minimized as much as possible, and the process is iterative. The line plant endpoints meet the following movement principles: (a) Prioritize the movement of 220kV plant endpoints in the line; (b) Prioritize the movement of plant endpoints with fewer outgoing lines. The number of plant endpoint movement steps is less than the maximum number of movement steps m. Preferably, when moving the coordinate points of the crossing lines, the two crossing lines first move the plant endpoint with the least outgoing lines, and then move the plant endpoint with the lower voltage level. If the crossing can be avoided and no new crossing is generated, this method is used. If it cannot be avoided, the crossing problem is retained and waits for the next step to be solved. For example, when the moving variable M value is 1, Figure 3 The T(3,2) station where the intersection occurs cannot be avoided regardless of whether it is moved up or down or left or right. In this case, the intersection is retained and can be manually intervened later.

[0047] Step 3: Reduce the lines that exceed the critical adjustment parameters, mark the hot spots according to the event types existing in the terminal plant, optimize and reduce the grid diagram based on the hot spot information, form a grid diagram optimized by terminal fusion hot spot information through manual fine-tuning, and overlay geographic related information on the grid diagram for display.

[0048] For long lines in the diagram that exceed the critical adjustment parameter n, the full-map operation is gradually reduced without generating more intersections, and the critical adjustment parameter n and the number of reduction layers r of the long lines are reasonably configured, so that the final longest line crossing grid p' does not exceed the number of reduction layers r. The longest line crossing grid p> critical adjustment parameter n, the number of reduction layers r ≦ critical parameter n, after adjustment and subsequent manual review, the unreasonable line distribution caused by the long lines is significantly improved. Figure 3 For example, if n is 3 and the number of layers r is reduced to 2, then after adjustment, the line that crosses 3-4 grids is adjusted to cross 2 grids, generating Figure 4 During the reduction process, no intersections can be added to the line.

[0049] The generated grid diagram terminal fusion hotspot information is optimized and reduced. The multi-source power grid information is integrated to obtain the terminal plant hotspot information, optimize and reduce the grid diagram, and the process can be iterative. First, the terminal plant is judged, and the plant connection lines are traversed. If all the outgoing lines are only related to another plant, it can be judged that the plant is a terminal plant. Then, combined with multi-source information, it is judged whether there is hotspot information in the plant, and the plant is marked with hotspots according to event types such as heavy load, overload, power protection, planned maintenance, temporary maintenance, defects, water supply, coal shortage, lightning activity, strong wind, heavy rain, ice cover, n-1 scanning alarm, etc. At the same time, for plants that do not have the above hotspot information at all, when it is judged that the whole plant is lightly loaded (load is less than L%, L is 20), a cold spot mark is added, and the lines are hidden and merged according to the settings to reduce the interference of non-important information in the grid diagram. Finally, manual fine-tuning is supported, and the automatically generated graphics are manually reviewed. Review whether the 500kV plant location is reasonable and adjust the location of the 500kV substation. During the adjustment process, the 220kV power plant in the 500kV area keeps the relative coordinates unchanged and moves synchronously with the 500kV power plant. Finally, the location of the adjusted 220kV power plant is checked to see if it is reasonable. The layout is optimized by manually moving the line and adding the key geographic coordinates of the corners. The grid diagram with terminal fusion hotspot information optimization is formed by modifying the intervention coordinates. Figure 5 .

[0050] The fusion display module supports the overlay of geographic related information on the grid map for display. Geographic related information includes natural meteorological information such as weather, lightning, wildfire, ice disaster, fault location, three-span line (across the line, across the railway, across the highway), personnel location, etc. The grid processing of the coordinates contained in the information is performed by overlaying as follows:

[0051] Query the plant and station associated with the geographic positioning information; calculate the geographic related information and the orientation and grid distance of the associated plant and station; place the natural meteorological information according to the relative orientation and grid ratio of the associated plant and station; place the fault location and three-span information according to the line length; place the personnel location information according to the work location (line or plant and station), so as to realize the unified placement of traditional power grid flow and geographic related information with coordinates.

[0052] The beneficial effect of the present invention is that, compared with the prior art, the present invention provides a method and system for optimizing the mapping of a provincial power grid network diagram integrating hot spot information, and combines the optimization of the provincial power grid network diagram generated by the power grid hot spot information, taking into account the accuracy of the relative geographical location and the rationality of the plant density, and realizing the synchronous display of information such as weather, three spans of lines, and personnel positions on the basis of maintaining the traditional information display of the network diagram. The generated new power grid network diagram is automatically distributed in combination with geographic information, combined with hot spot information, reduces the general information of the power grid and the display of the plant, highlights the display of key plants, increases the unified layout of geographical related information, and allows the dispatching personnel to focus more on the weak links of the power grid and the operation hot spot information. This method can be used not only in the power dispatching profession, but also in various professions such as planning, operation inspection, and safety supervision. At the same time, due to the real-time nature of its mapping, it can flexibly add and delete some plants and lines, so it can perform fault deduction and display the historical state, current state, and future state of the power grid.
