Galloping Detection of Transmission Line without Spacer Based on Cumulative Gray Model and Random Gray Fluctuation Field
摘要
Abstract
The galloping of transmission lines is a threat to the safty of the power system.Currently,the galloping amplitude was mainly determined by detecting the swing of spacers.However,there was no practical detection method for transmission lines without spacers.A simple,effective and novel method was proposed for detecting the galloping of transmission lines.Firstly,the background model was built by counting the data of grayscale changes over time.Then,a random grayscale fluctuation field was intro-duced to describe the random grayscale fluctuations caused by internal and external factors of the camera.The influence of these fluctuations on the background difference was eliminated by combining the 3σ cri-terion,thus achieving accurate segmentation of the transmission line area.Finally,the movement of the transmission line was mapped to generate a cumulative grayscale model,and its movement amplitude at different positions in a short time was calculated.By comparing with the line width of the transmission line itself,a threshold was set to determine the dancing.The algorithm was validated using field data col-lected by tower cameras,achieving a detection accuracy of 95.5%,a false positive rate of 5.7%,and a false negative rate of 2.0%.This method demonstrated strong robustness and applicability.关键词
