High pressure H.APF active power filter and reactive power compensator in technical areas: low power factor load situations ◆ harmonic control industry, the need for reactive power compensation ◆ widely used in electrical, mechanical and chemical industries ◆ residential area electricity Dynamic power compensation load ◆ high voltage power dynamic compensation have occasion H.APF active power filter and reactive compensation devices demanding integrated into the twenty-first century, the high-power electronic devices has been the rapid development of harmonic control, IGBT technology increasingly mature, which created adequate conditions for the high-power active filter APF research and development from the laboratory to the real market applications. Using the power active filter to eliminate harmonics is the most effective solution for a wide range of market needs. Han Wei Harbin Electrical Equipment Co., Ltd. is dedicated to dynamic reactive power compensation and filtering equipment development and production of high-tech enterprises, Wei Han Electric in cooperation with Harbin Institute of Technology, specialized in research and development for nearly Active Power Filter years of history, development, production of WHAPF series active power filter system has been successfully used in automotive applications, ports, petrochemical, textile and other industries. APF active power filter means is a dynamic new power electronic devices suppress harmonics and dynamic reactive power compensation system. Real-time detection of the load current harmonic and fundamental reactive component, the control system fast computing IF harmonic control, three-phase parallel converter compensating current injected into the system, the compensation current and load current of harmonic currents equal and opposite directions, cancel each other out, to ensure the final sinusoidal current flow into the system. Also harmonic control manufacturers, the device only way to change settings, change the compensation current phase angle injection system, can achieve harmonic filter load while compensating reactive power, to improve the power factor, improve power quality purposes .
