| Abstract: | The operation condition of AC filter,an important part of DC transmission system,affects directly power transmission of the HVDC power transmission.In this paper,the unbalance abnormality of C1 capacitor of AC filter is analyzed with combination of the actual operation experience of AC filter,finding the unbalance fault of C1 capacitor of AC filter is due to both capacitor proper and inter?layer discharge.The cause of the fault is analyzed,studied and verified by the PSCAD/EMTDC simulation software and the improvement measures for the fault of capacitor proper and inter?layer discharge is proposed,which has a practical significance to the safe operation of AC filter in the converter station. |
