The invention relates to a power grid model generation method based on a splicing technology, and the method comprises the following steps: S1, reading an external network model of a QS file of a national dispatching center through a provincial dispatching full-model network analysis application; s2, reading an in-province power grid model through a province dispatching full-model network analysis application; s3, splicing the power grid models in the step S1 and the step S2; s4, performing state estimation calculation on the spliced power grid model; s5, after calculation is completed, storing the current result as a historical section. According to the method, the structure of the power grid model generated after splicing is more accurate and complete, the accuracy of application calculation results such as static safety analysis and dispatcher power flow is improved, and safe and stable operation of the power grid is guaranteed.
Description
Technical field[0001]The present invention belongs to the field of power system automation, and in particular, the present invention relates to a grid model generation method based on splicing techniques.Background technique[0002]With the rapid formation of high-pressure DC mixed larger grids and modern production on energy quality, the operation and control of the power system becomes more and more complex. Network analysis applications for smart grid scheduling control systems include state estimates, static security analysis, dispatcher trends, short circuit current calculations, sensitivity analysis and other functions, the accuracy of their calculation results directly affect the level of operating control of the grid.[0003]At present, the national power grid is the main grid, and the provincial grid models are only included in the provincial power grid model, and the provincial power grid model is only affected by the province's direct adjustment plant. Accuracy of the calcula...
