The rectifier group is an important equipment for the electrolytic aluminum rectification system. The valve short circuit and valve breakdown failure, which would cause serious accidents, often happened. The sensitivity of the existing arc protection action is affected by the fault position, and the equipment burning accident, caused by the failure to detect in time, happened frequently. This paper derived the AC/DC differential protection algorithm of the rectifier group which was based on the structure of the rectifier group and conceived from the idea of "valve short circuit protection". The simulation results showed that the algorithm can identify the fault, which occurred inside, quickly and accurately. This algorithm provides a new method for the protection of the rectifier valve group, which fills the gap of the differential protection of the rectifier valve group.
