Embodiment Construction
[0031] This embodiment provides a power grid information verification method, including the following steps:
[0032] (1) Obtain the power grid information data table, start topology calculation with the balance node or feeder terminal in the power grid information data table as the starting point, and mark a balance node or feeder terminal for each topology-connected device in the power grid information data table The topological network is obtained, and the topology direction is marked during the topology calculation process; among them, after marking a balanced node or feeder terminal for each topology-reached device, it means that the device belongs to a power grid starting from this balanced node or feeder terminal; Moreover, each device should belong to a power grid, so it is impossible for a certain device to be marked with a balance node or a feeder terminal twice (that is, a ring network point appears), and it should not appear that a certain device is not marked with ...

The invention relates to a power grid information verifying method and a power grid information verifying system. The method comprises the steps of: after acquiring a power grid information data table, using a balance node or a feed line terminal in the power grid information data table as a starting point for topological calculation; after topological calculation, judging whether a topological network acquired has a looped network or not; if so, positioning a looped network point and using a reverse point-to-point topological method to inquire a device in a looped network path; providing special position and connecting relation of error data of the looped network and assisting to cut off the looped network with error data; judging whether island error exists or not, using any one device in the island as an initial point for topological calculation, and analyzing the inner connecting relation in the island; dividing the device with uniform connecting relation into an island sub-area, and assisting the user to access a power supply point for the device in each island sub-area. The technical scheme provided by the invention can effectively avoid the problem that in the prior art, basic power grid data is subjected to looped network and island error.
Description
technical field [0001] The invention relates to the technical field of computer applications, in particular to a method and system for verifying power grid information. Background technique [0002] With the continuous development of my country's macro-economy and the continuous acceleration of urbanization, higher requirements have been put forward for the development of power grids, both in terms of power supply demand, and in terms of power supply reliability and security. The city is the main load center of the power system. Whether the urban power grid operates well depends on whether the planning and construction of the urban power grid is scientific and economical. For power supply companies with huge fixed assets, grid planning is crucial to the survival and development of power supply companies always play a decisive role. Therefore, in the face of the new situation, power grid planning needs to be committed to the coordinated development of power grid construction...
