Abstract
To solve the problem of harmonic level evaluation for AC arc-furnace supply area, this paper analyses the synchronous measuring data of harmonic current in AC arc-furnaces with functional analysis, verifies harmonic current released from AC arc-furnaces with independence and orthogonality approximately between each other, proves superposition of harmonic current in accordance with root of sum of squares, derives the formula for evaluating harmonic voltage level of PCC at which AC arc-furnaces were connected. The formula is verified Actually, it shows that multi-arc-furnaces harmonic current can be largely counteracted each other, If these AC arc-furnaces were connected to a PCC in which short-circuit capacity is enough for that the superposed harmonic current of AC arc-furnaces can be electromagnetic compatible, then power quality of the PCC can reach the qualified level.
