Dynamic reactive power compensation

Dynamic reactive power compensation of traditional harmonic compensation and without an alternative method of reactive current is equipped with passive filter, usually by the power capacitor, inductor and resistor on parallel combination and, the method can compensate harmonic, and can compensate 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.
Dynamic harmonic elimination reactive power compensator, which is a fully automatic dynamic reactive power compensation device with a microprocessor controlled thyristor switched capacitor group, is a new generation product of reactive power compensation equipment. Such products using microprocessors without reactive power real-time monitoring crystal brake tube zero transition process of fast switching, harmonic current suppression and other advanced technology, suitable for application in complex industrial environment, can accurately and quickly, without transient disturbance dynamic reactive power compensation, effectively improve the high power factor of electric equipment, improving the output of power equipment and to improve the quality and reduce the loss, achieve the purpose of saving energy and reducing consumption. At present, the products of this kind of technology are more stable and efficient, so it has more application in energy saving and consumption reduction. Such as YTECI and so on are using such technology.
