Embodiment Construction
[0042]In the traditional method of transmission line defect diagnosis, the temperature value of the transmission line is mainly collected in real time. When the temperature value of the transmission line reaches a certain threshold, the transmission line is considered to be in an abnormal working state. However, for transmission lines, the initial stage of fault defects often does not directly cause the temperature to rise too high, but presents certain characteristics in temperature changes. At the same time, changes in the surrounding environment and current changes will also promote transmission lines. defect. For this reason, the defect fault of the transmission line is determined by the temperature threshold threshold, which is often manifested through the temperature rise after the fault of the transmission line is relatively serious, and the damage to the transmission line is more serious, which is not conducive to the maintenance and maintenance of the transmission line...

The invention discloses a defect diagnosis method for a power transmission line. The method comprises the steps of collecting temperature characteristic data, current-carrying characteristic data andenvironment characteristic data of a to-be-detected power transmission line; inputting the temperature characteristic data, the current-carrying characteristic data and the environment characteristicdata into a defect discriminator obtained by pre-training, and determining whether the power transmission line to be detected has defects or not; wherein the defect discriminator is a model of the corresponding relationship between the defects of the power transmission line and the temperature characteristic data, the current-carrying characteristic data and the environment characteristic data ofthe power transmission line. According to the method, the influence of factors in various aspects such as temperature, current and environment on normal operation of the power transmission line is fully considered, the power transmission line is accurately estimated in advance, maintenance personnel can be reminded as soon as possible for timely processing, and high-efficiency operation managementof the power transmission line is facilitated. The invention further provides a defect diagnosis device and equipment for the power transmission line and a computer readable storage medium, which have the above beneficial effects.
Description
technical field [0001] The invention relates to the technical field of power grid security, in particular to a fault diagnosis method, device, equipment and computer-readable storage medium for transmission lines. Background technique [0002] Driven by the background of the State Grid's construction of "three types and two networks" and market trends, the construction of the power Internet of Things has opened up a new path for safer operation of the power grid, leaner management, more precise investment, and better service. [0003] The transmission line is an important part of the power system. Whether the transmission line can transmit the current energy normally and efficiently is a problem that needs to be paid attention to in the normal operation of the power grid. Therefore, during the transmission operation of the transmission line, temperature is one of the key factors that characterize the normal operation of the transmission line. If the temperature of the transm...
