The invention relates to a DC line voltage measurement anomaly detection method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a plurality of first bus voltages corresponding to a DC line to be measured, second bus voltages corresponding to the first bus voltages, and DC line current; based on each first bus voltage and the second bus voltage, respectively obtaining a direct current line voltage corresponding to each first bus voltage; constructing a unary linear regression function for the DC line by using the DC line voltage corresponding to each first bus voltage and the DC line current corresponding to each first bus voltage; taking an intercept corresponding to the unary linear regression function as a DC line voltage measurement deviation value of the DC line; and obtaining a voltage measurement anomaly detection result of the DC line according to the DC line voltage measurement deviation value. By adopting the method, the detection accuracy of t
