series reactor
In the current power system, the emergence of more and more harmonic sources, whether industrial or civilian, is increasingly polluting the power grid. Resonance and voltage distortion will cause many other power equipment to operate abnormally or even fail. Generated, tuning the reactor can improve and avoid these situations. After the capacitor and reactor are combined in series, the resonant frequency will be lower than the minimum of the system. Realize capacitive at power frequency to improve power factor, and inductive at resonant frequency, so as to prevent parallel resonance and avoid harmonic amplification. For example, when the system measures the 5th harmonic, if the impedance is selected properly, the capacitor bank can absorb about 30% to 50% of the harmonic current.
