Embodiment Construction

[0051] The embodiment of the present invention provides a GIS-based distribution network line loss data acquisition method and related devices, which are used to solve the insufficient accuracy of the results caused by manually importing the data required for the theoretical line loss calculation of the distribution network in the prior art , the cost is high, the calculation efficiency is low, and the technical problems that cannot reflect the economic benefits of distribution network operation and planning in time.

[0052]The functional characteristics of the current GIS system mainly include simulating the real power grid model and assisting users in power grid analysis. To simulate a real power grid model, it is necessary to graphically display the power grid equipment and truly reflect the geographical location of each equipment in the system; it is also necessary to establish a topological relationship between equipment and equipment, so as to be able to simulate and rea...

Abstract

The invention discloses a GIS-based power distribution network line loss data acquisition method and a related device, and the method comprises the steps: obtaining to-be-analyzed power distribution network data, and constructing a GIS graph model, wherein the GIS graph model comprises a connection point model and an equipment model; exporting a CIM file from the GIS graph model according to a preset CIM exporting rule; analyzing the CIM file by adopting a preset CIM structure template to obtain equipment parameters of the equipment model and connection parameters of the connection point model; constructing an association relationship table by adopting the equipment parameters and the connection point parameters; according to the association relationship table, constructing a preliminary grid structure topological graph by adopting the connection point model and the equipment model; simplifying the preliminary grid structure topological graph to obtain a simplified grid structure topological graph; extracting line information of a power distribution network line from the simplified network frame topological graph, and generating a line loss calculation data acquisition table. According to the method, the workload of data preparation in the line loss calculation process is reduced, manual intervention is not needed, the calculation cost is reduced, and the accuracy of theoretical line loss calculation is improved.

Description

technical field [0001] The invention relates to the technical field of data conversion, in particular to a GIS-based distribution network line loss data collection method and a related device. Background technique [0002] The distribution network refers to a mesh power supply line network composed of multiple power supply lines, which is a large-scale power supply line. Optimizing the economic operation of the distribution network refers to rationally adjusting the load current and operating voltage of the power supply network to minimize the load on the transformer at the power supply end of the power grid and minimize the line loss of the power grid, thereby reducing the total loss of the entire power supply line. Through effective theoretical line loss calculation, it is possible to reasonably adjust the working voltage and current of the transformer at the power supply end based on the actual power demand of the power consumption place, so as to achieve the purpose of r...
