Abstract

The invention relates to a self-driven sensing method for the galloping state of a power transmission line, and belongs to the technical field of intelligent power grids. The method comprises the following steps: S1, establishing a test system of a swing type electromagnetic vibration energy collector, simulating galloping states of different power transmission lines by utilizing a vibration exciter to obtain corresponding output electric signals, and taking the output electric signals as system self-driven sensing characteristic parameters; analyzing a change rule between the output electricsignal of the collector and the line galloping state parameter, constructing a qualitative relationship between the self-driven sensing characteristic parameter and the line galloping state, and establishing a self-driven sensing characteristic parameter information database of different line galloping states; and S2, establishing a self-driven sensing system for monitoring the galloping state ofthe power transmission line, comparing and analyzing the acquired electric signals with the self-driven sensing characteristic parameter information in the database established in the S1 by adopting aclustering analysis method, judging the galloping state and degree of the line, and realizing intelligent sensing of the galloping state of the power transmission line.

Description

technical field [0001] The invention belongs to the technical field of smart grids and relates to a self-driven sensing method for galloping states of transmission lines. Background technique [0002] In recent years, my country's power system transmission network is developing towards full coverage, and transmission lines are a crucial part of power grid construction, directly affecting the safe and stable operation of the power system. The power transmission line is exposed to natural conditions for a long time, not only to face natural damage such as subsidence, landslide, pollution, strong wind and lightning strikes, but also to bear the internal pressure of normal mechanical loads, ice loads, mechanical failures, electrical loads and other Line dancing problem caused by random factors. Galloping of transmission lines is prone to accidents such as line flashover tripping, hardware damage, and even disconnection, which seriously threatens the stable operation of the powe...
