Abstract

The invention discloses an SER signal processing method and device for a high-voltage direct-current power transmission monitoring system. The method comprises the following steps: acquiring an original SER signal in the high-voltage direct-current power transmission monitoring system; invalid interference signals in the original SER signals are screened out, and the SER signals with accurate information are obtained; and performing simplification processing on the SER signal with accurate information to obtain a processed SER signal. Through intelligent screening and simplified processing of the direct current signals, the number of equipment monitoring signals needing to be processed is reduced, the efficiency of equipment monitoring is improved, accident time information is simplified, and the efficiency of accident processing is improved.

Description

technical field [0001] The invention relates to the technical field of power equipment control, in particular to a method and device for processing a SER signal of a high-voltage direct current transmission monitoring system. Background technique [0002] With the development of HVDC transmission technology, many HVDC transmission projects have been constructed successively. At the beginning of the design of the DC converter station, the operator hoped to obtain enough equipment monitoring signals (including main equipment and auxiliary equipment), but after a long period of operation, the operator found that too many of the signals were repeated signals or could not be expressed correctly. The signal of the device status, the granularity of the signal is too fine. Therefore, it is necessary to intelligently process the monitoring signal, so that the signal can be simplified and can accurately express the information. [0003] In the prior art solution, the following solut...
