Typical Case 2 of Harmonic Management in Tobacco Industry: (Xuzhou Cigarette Factory) Background of the project: In the current production facilities of cigarette factories, a large number of frequency converters are used, and the frequency converter is a typical non-linear power source, which results in high current harmonic content of its power supply system, which seriously increases the harmonic loss of the power supply line. Harm to the safe operation of other electrical equipment. The various departments of the cigarette factory have become more and more aware of energy conservation and consumption reduction and harmonic pollution control. Therefore, harmonic control of the power supply system has become a key project of the cigarette factory.

Background of the project:
In the current production facilities of cigarette factories, a large number of frequency converters are used, and the frequency converter is a typical non-linear power source, which results in high current harmonic content of its power supply system, which seriously increases the harmonic loss of the power supply line. Harm to the safe operation of other electrical equipment. The various departments of the cigarette factory have become more and more aware of energy conservation and consumption reduction and harmonic pollution control. Therefore, harmonic control of the power supply system has become a key project of the cigarette factory.
Governance plan:
According to the above situation, our company's data analysis of the field test found that the harmonics of the cigarette factory mainly generate a large number of current harmonics from the inverter. For this reason, we choose the parallel active power filter (SPA3-XXX/0.4) independently developed by our company. A programme for local and centralized governance.
Governance effect:
GoodPower
       It can be seen from the above data that before the active power filter is put into operation, the inverter phase current drops from 660A before compensation to 626A, which is 5% lower than before the filter is input; the fifth harmonic current drops from 111A before compensation to compensation. The 13A is 88% lower than before. It can be seen that the input of the active power filter has achieved good harmonic elimination and energy saving effect.
