Analysis of the Transfer Characteristic of DC Voltage Divider in UHVDC System and Its Transient Response
DC voltage divider is the data source of the control and protection system in UHVDC. The measurement results directly affect the control loop of the DC system and are closely related to the reliability of the DC transmission operation. For example, since the control and protection of DC transmission are based on the measurement value of the secondary side of DC voltage divider, if its characteristics are not considered in the control, the control and protection performance will inevitably decline. In this paper, aiming at the DC voltage divider commonly used in UHVDC transmission projects, combined with the actual parameters, the broadband transfer characteristics of the DC voltage divider is proposed, and the simulation and verification are carried out. The conclusions obtained can provide a reference for improving the accuracy of the model and ensure the safe and stable operation of UHVDC
