Power grid electric power infrastructure safety assessment analysis method and system, and storage medium

Abstract

The invention discloses a power grid electric power infrastructure safety assessment analysis method and system and a storage medium, and the method comprises the steps: dividing a target power transmission tower into a tower head structure, a tower body structure and a tower leg structure, carrying out the single-body architecture stability analysis of each composition structure, assessing the single-body architecture instability index corresponding to each composition structure, and carrying out the analysis of the single-body architecture stability. Meanwhile, connection bearing stability analysis is carried out on each composition structure, and a bearing instability index of the tower body to the tower head and a bearing instability index of the tower leg to the tower body are evaluated, so that whether the target power transmission tower is suitable for continuous operation or not is comprehensively judged by combining the evaluation results, and comprehensive evaluation analysis of the operation safety of the power transmission tower is realized; the defect that in the prior art, power transmission tower operation safety evaluation is too one-sided is overcome, whether the target power transmission tower is suitable for continuous operation or not is judged through the evaluation mode, and the reliability of the judgment result can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of power facility safety assessment, in particular to a power grid power infrastructure safety assessment and analysis method, system and storage medium. Background technique [0002] In the power system architecture, overhead lines have become the most important type of transmission lines due to their advantages of low one-time investment costs during construction, easy construction, and short construction periods. However, overhead lines need to be erected at high altitudes. It has become the key construction of overhead line construction. At present, the overhead fixation of transmission wires is basically fixed by transmission towers. As the infrastructure of overhead lines, transmission towers are responsible for protection and support. It will cause power transmission failures of overhead lines, and even cause power transmission interruptions, which will seriously affect the transmission stability of o...

Problems solved by technology

In the prior art, the focus of evaluation on the operation safety of transmission towers is mostly on the stability of the components of the transmission tower, ignoring the load-bearing stability between the components. When the load-bearing stability between the components is not good , the side being carried is prone to breakage or even collapse, which will not only affect the transmission stability of the overhead line, but the collapsed structure will also cause huge loss of life and property to the passing people below.

[0004] To sum up, it can be seen that simply evaluating the stability of each component structure of the transmission tower is obviously too one-sided, and the evaluation results cannot fully reflect the operational safety of the transmission tower
