In response to the issue of abnormal response in DC voltage measurement of converter stations, based on the analysis of the principle of DC voltage control strategy in the control system, simulation analysis is conducted on the abnormalities of different DC voltage measurement points in the converter station. The characteristics of changes in DC field state variables during abnormal DC voltage measurement are summarized, and a fast diagnostic model for abnormal DC voltage measurement in the converter station is constructed. The numerical results show that the proposed method has a high recognition rate, is simple and effective, and can be applied to identify abnormal DC voltage measurements.
