Abstract

The invention relates to the technical field of power grid planning and design, in particular to a transformer substation grounding parameter determination method and device, a terminal and a storage medium, and the method comprises the steps: firstly obtaining a grounding grid universal design scheme and soil layer resistivity, then determining equivalent to uniform soil resistivity according to the soil layer resistivity, and finally determining the grounding parameter of a transformer substation according to the soil layer resistivity. And calculating the resistance of the grounding grid according to the grounding grid general design scheme, the equivalent resistivity and the grounding resistance calculation model. According to the method, after a general design scheme is obtained, the input quantity of parameters is reduced, the parameters are equivalent to uniform soil, the calculation process is simplified, and meanwhile the calculation precision after simplification is improved as much as possible. The method is based on a simulation calculation model, the accuracy is obtained, the method is applied in the form of a rapid calculation tool, and the economical efficiency of the grounding grid design is improved in design; meanwhile, the required calculation amount from modeling to grounding calculation is greatly reduced through grounding simulation, and quality improvement and efficiency improvement of substation engineering construction work are promoted.

Description

technical field [0001] The invention relates to the technical field of power grid planning and design, in particular to a method, device, terminal and storage medium for determining grounding parameters of a substation. Background technique [0002] The accident or expansion of the accident caused by the grounding resistance of the grounding system not meeting the requirements. In order to maintain the safe and reliable operation of the power system and ensure the safety of people and electrical equipment, the cost of the grounding grid is also on the rise. Grounding design is a key process in the design and review of power transmission and transformation projects. [0003] At present, two methods are mainly used to calculate the grounding parameters. One is to conduct grounding grid design and parameter safety verification according to the "Code for Grounding Design of AC Electrical Installations", and calculate according to empirical formulas. The second is to use the Ca...
