Automatic Detection Method for Preventing Abnormal Mechanical Tripping of Short Distance Power Supply Lines in Coal Mines
摘要
Abstract
In order to avoid major accidents in coal mine power supply and ensure the safety of power supply lines,an automatic detection method for preventing abnormal mechanical tripping of short distance power supply lines in coal mines is proposed.The Iterative method is used to preprocess the observed time series power supply line data,remove its noise points,and obtain the preprocessed power supply line fitting data.The Cosine similarity is used to calculate the abnormal correlation between the two power supply line vectors in the direction measurement features,and the final feature subset is obtained to achieve the abnor-mal feature extraction of mechanical tripping.The extracted feature values as variables are input into the established automatic detection model for preventing mechanical tripping to calculate the set of equipment state variables and objective functions,and complete abnormal tripping detection.The experimental results show that the proposed method can accurately detect the abnormal mechanical tripping of short distance power supply lines in coal mines,take timely response measures to ensure the safe and stable operation of electricity.关键词
