Traditional harmonic and reactive currents
An alternative approach to traditional compensating harmonic and reactive current is equipped with passive filter, usually by the power capacitor, inductor and resistor on parallel combination and, the method can harmonic compensation, and compensation of reactive power. Currently our country commonly used reactive power conditioning equipment is mechanical shunt reactors, switched capacitor, the stationary type pressure regulating means, because the adjustment is not continuous, slow response speed, it is difficult to meet the rapid changes in system operating mode of demand. And another surge of static var compensator (SVC), response speed is very fast, but due to a constant impedance characteristics, making in the low voltage to provide the required reactive power support, so deal with emergencies ability is weak, and in order to suppress the harmonics must be installed in the filter, covers an area is larger, in addition, the SVC device easily lead to oscillation system. In contrast, the novel reactive power compensator STATCOM is a more effective means for adjusting voltage, it without reactive current output can be constant in a large range of voltage change, in the low voltage can still provide strong reactive support, and from perceptual to the content of the full range of continuous adjustment. The company provides professional dynamic reactive power compensation!
