The invention relates to a direct-current transmission line protection system resetting method and device, equipment and a storage medium. The method comprises the steps of: acquiring electrical measurement data from a high-voltage direct-current transmission system through a direct-current transmission line protection system, and generating a protection action signal according to the electrical measurement data, wherein the protection action signal comprises a first protection action signal, and the first protection action signal is used for indicating the high-voltage direct-current transmission system to restart; if the direct-current transmission line protection system receives a preset reset signal input by a user and the protection action signal is a first protection action signal, generating a zero clearing signal according to the first protection action signal and the preset reset signal; and resetting the direct-current transmission line protection system according to the reset signal. According to the direct-current transmission line protection system resetting method and device provided by the invention, the reliability of the direct-current transmission line protection system can be improved.
Description
technical field [0001] The present application relates to the technical field of high voltage direct current transmission, in particular to a reset method, device, equipment and storage medium of a protection system for direct current transmission lines. Background technique [0002] During the HVDC transmission process, the HVDC line protection system can output a restart protection action signal to the HVDC system when the HVDC system fails. After receiving the restart protection action signal, the high-voltage direct current transmission system executes the restart protection action, and needs to reset the counter in the direct current transmission line protection system, the initial value of the protection action signal, etc. [0003] Traditionally, an automatic reset method can be used to reset the DC transmission line protection system. However, in the traditional automatic reset method, when the DC trigger pulse signal that triggers the operation of the converter in ...
