The invention provides an intelligent laying design method of a substation grounding grid. The method comprises the following steps of establishing an interface capable of being compatible with CAD (Computer Aided Design) and three-dimensional display; establishing a grounding grid design input-output and intermediate result database; and calculating a grounding grid design and displaying results. The intelligent laying design method of the substation grounding grid provided by the invention has the following effects: a visual CAD interface and a flexible input-output interface interactive structure are adopted, thus designers can select the areas where the grounding grid is laid according to the area size of the substation and flexibly select the needed grounding materials and a given initial interface; besides, the method provided in the invention has the functions of automatically calculating the touch voltage, the step voltage and cross section check of the grounding grid, and automatically outputting a grounding grid design calculation result table, and performing three-dimensional display on the laying effects. The method provided in the invention further has a function of being in economic and technical comparison with other grounding materials and recommending an optimal grounding scheme, and has the characteristics of being accurate, highly efficient, flexible, economic and visual.
Description
technical field [0001] The invention belongs to the technical field of power grid planning and design grounding grid design, in particular to an intelligent laying design method for a substation grounding grid. Background technique [0002] The substation grounding grid has important practical significance for the normal operation of the power system and the power grid. It not only has a certain protective effect on the power equipment and power system of the substation, but also a powerful guarantee for the safety of life and property of the staff in the substation. [0003] The main grounding network of the current substation is an important part of the overvoltage protection device of the power system. It is mainly composed of artificial grounding bodies laid horizontally, supplemented by vertical grounding bodies, and constitutes the artificial grounding device of the substation. At present, the commonly used grounding grid design and calculation methods include hand cal...
