Research on Intelligent Checking of Power Grid Equipment Status and Research and Judgment of Operation in Place

Aiming at the problem of high frequency of power grid accidents caused by poor operation status of power grid equipment and large errors in actual operation and check, the intelligent check and operation in place judgment technology of power grid equipment status is studied. The basic steps of intelligent verification of power grid equipment state are electrical quantity collection, preprocessing, feature extraction and classification recognition. The collected fault traveling wave signals of power grid equipment are decomposed by variational mode decomposition, and the natural frequency of fault traveling wave and fault line fault traveling wave are compared. So as to judge the fault interval and calculate the accurate fault distance, check the results and complete the research and judgment of power grid equipment operation in place. The results show that under the application of this method, the state check results of power grid equipment are in line with the actual situation, and the fault distance error is small, which achieves the expected goal.
