Harmonic Power Factor Compensation Power Quality Improvement Economical Solution
No.1-1
Description
Power quality improvement economical solution?In practical application, the traditional passive filter capacitor compensation and passive filter are commonly used in quality management, Green Power APF and SVG can work together with traditional method, realize more reliable, more convenient and more economic compensation, which is our unique solution for power quality improvement.Capacitor reactive power compensation+SVGThe traditional reactive power compensation adopt slow switching device for capacitor switching, there is problem of differential compensation, poor compensation accuracy, slow response speed. SVG adopts high speed switching device to generate the compensation current, without the problem of compensation accuracy and slow response.
For low cost considerations, most or half compensation is compensated by capacitor groups, the remaining is completed by SVG, which ensure smooth compensation, also low cost, namely SVG+C method. ?Dynamic reactive power compensation method comparisonNameTSCSVG+CSVGOutput reactive powerGroup switching, rough compensationLinear output, accurate compensationLinear output, accurate compensationCompensating effect0.9 above0.99, could be partially sensitive0.99, full resistive to full capacitiveTotal response time>100ms>30ms<10msFilter abilitynoPartial specified harmonic2-13 harmonicThree-phase unbalancenoObvious effectThoroughly solve three-phase unbalancedSupport voltagenoPartial capacity support voltageFull power support voltagePriceRelative lowThe cost is little higher than TSCHigher than TSC Traditional Passive filter+APF The traditional harmonic compensation is the passive filter of the capacitance and resistance, which has the disadvantages of low compensation precision, slow response, poor reliability and limited harmonic compensation.
APF adopts high speed switching device to generate the compensation current, there is no compensation accuracy problem, and also has fast response.
