Abstract:

The nonlinear power electric device generates harmonic current that will make EMI and reduce power factor.The harmonic filtering equipment composed of condenser and in-line reactor has the functions of harmonic filtering reactive compensation.Unlike the traditional condenser set which increases the power factor and amplifying higher harmonic meanwhile under operation,harmonic filtering equipments absorb the harmonic and improve the quality of power supply.In the reactive compensation system,the capacitance shall be calculated according to the power to be compensated,and the in-line resonant frequency in series resonant circuit will be determined by the resistance.The resonant frequency must be less than the min sub harmonic that may happen.

Key words: Harmonic;single tuned reactive-load compensation equipment;series reactive harmonic filtering equipment
