  • METHOD FOR DETECTING ABNORMAL DIRECT CURRENT VOLTAGE MEASUREMENT IN HIGH VOLTAGE FLEXIBLE DIRECT CURRENT TRANSMISSION SYSTEM
    Publication number: 20240097434
    Abstract: A method for detecting abnormal direct current voltage measurement in a modular multilevel converter high voltage direct current transmission system is provided. In the method, a valve group voltage at a detection pole is obtained, voltages at voltage measurement points at the detection pole are collected, and comparison and determination are performed based on the actual arrangement of the voltage measurement points, and then whether an abnormal measurement occurs at each of the voltage measurement points is determined.
