Problems solved by technology

[0003] The development of smart grid is already a trend of the times, and now many researchers also apply various intelligent algorithms to the evaluation of the operation status of transmission lines, such as evaluation methods based on fuzzy comprehensive evaluation and neural networks. However, this evaluation method has the following disadvantages: 1. The training and modeling process is too complicated, the workload is large, and the practicability is not strong; 2. Only a single line device and state quantity are considered. In terms of relevant evaluation, it is difficult to reflect the real state of transmission line operation without considering the time period of line evaluation and the relevant characteristics of spatial distribution.
These deficiencies will make it difficult to apply these intelligent methods in the engineering practice of the evaluation of the operation status of transmission lines.

Abstract

The invention relates to a power transmission line operation state assessment method based on a big data portrait technology. The method includes two parts: a multi-dimensional power transmission lineportrait part and a multi-layer architecture power transmission line equipment evaluation part; each parameter of the power transmission line portrait is determined by using each system of the powergrid; and each parameter is scored by utilizing an accumulative score deduction method, the scores are substituted into the power transmission line equipment state evaluation model to obtain operationstate evaluation scores of each tower section, and accumulating the comprehensive evaluation scores of each tower section on the power transmission line to finally obtain the overall operation stateevaluation of the power transmission line. According to the invention, through organic combination of the multi-dimensional power transmission line portrait and the power transmission line operation state, the evaluation of the power transmission line operation state is simply and comprehensively realized.

Description

technical field [0001] The invention relates to the field of power system security, in particular to a method for evaluating the operating state of a transmission line based on big data portrait technology. Background technique [0002] As people's dependence on electricity continues to increase, the requirements for the reliability and safety of power supply in the power system are also getting higher and higher. As the main part of the power system, transmission lines bear Line faults will cause large-scale power outages, and the economic losses caused by them are immeasurable. In order to ensure the safe and reliable transmission of electric energy, it is of great practical significance to evaluate the operation status of transmission lines. [0003] The development of smart grid is already a trend of the times, and now many researchers also apply various intelligent algorithms to the evaluation of the operation status of transmission lines, such as evaluation methods ba...
