A comparison of different compensating modes for detrimental power components in electric networks

The instantaneous power theory was used to obtain different load power components. The possibility of compensating for detrimental power components by means of different compensating modes using hybrid power electronic active filters was investigated in order to obtain the most economically acceptable compensator topology. The theoretical analysis indicates that 85% and 90% of the 5 th and 11 th harmonic, respectively, can be compensated for, while 120% and 112% of the 7 th and 13 th harmonic are compensated. It is shown that a large portion of the detrimental load power can be compensated without a large and expensive energy storage element.<
