Electrical safety protection parameter checking method based on edge calculation and cloud platform

Abstract

The invention discloses an electrical safety protection parameter checking method based on edge calculation and a cloud platform, which belongs to the electrical field and comprises the following steps: S1, establishing a topological model of an electrical loop and importing the topological model into an edge calculation controller and the cloud platform; s2, obtaining a protection parameter valueof the protection equipment, importing the protection parameter value into an edge calculation controller and a cloud platform, and constructing a two-dimensional table containing protection equipment attribute-protection parameters; s3, based on standards and specifications of national, industrial and customer specific scenes, constructing a two-dimensional table containing legal protection attributes-legal protection parameters according to the two-dimensional table format in the step S2; s4, checking the legality of all the protection parameters of the two-dimensional tables in the S2 andthe S3; s5, checking the association rationality of each level of the two-dimensional table in the step S2; and S6, outputting a check result and displaying the check result to the user. The method has the beneficial effect that the model selection of the protection equipment and whether the coordination and cooperation between the protection equipment are reasonable or not can be checked.

Description

technical field [0001] The invention relates to the field of electrical safety, in particular to an electrical safety protection parameter checking method based on edge computing and a cloud platform. Background technique [0002] For the protection of the user-side electrical circuit, protection devices of different models and specifications are usually deployed in accordance with the configuration scheme of no less than "three-level power distribution and two-level protection". These protection devices are automatically identified according to the electrical quantity sensed by the installation location. Short circuit, overload, leakage and other abnormal states, when the electrical quantity data does not meet the set protection parameters, the protection device will trip and cut off the power. These electrical quantities are mainly current, leakage current, voltage, and sometimes data such as frequency and power. [0003] In reality, unreasonable selection of protection e...

Problems solved by technology

[0003] In reality, unreasonable selection of protection equipment or unreasonable protection parameter settings often occur, resulting in short circuit, severe overload, or serious leakage of electricity in the electrical circuit, and the protection equipment still does not trip due to the above situation due to excessive parameter settings. , resulting in electrical fires or personal electric shock casualties;

[0004] The unreasonable protection parameters are mainly manifested in two aspects: one is that the protection parameters are unreasonable or the selection is unreasonable, and the protection fails due to non-compliance with national regulations; Protection action is unreasonable
