| Abstract: | AC filter protection in HVDC transmission system is introduced. Firstly the characteristic of the AC filter and the influence of the different working conditions are analyzed, such as the floating harmonic current, transient made by control system and external fault, etc. The integrated scheme and essential principle of the protection of AC filter is then proposed. Emphases are put on the differential protection, the harmonic overload protection and the capacitor protection etc. All the principles are verified under lab and real operation condition of power system. |

| Keywords: | AC filter capacitance unbalance protection harmonic overload protection low unbalance protection low capacitance protection |
