Low-voltage active power filter APF Technical support: With the significance of the development of power electronics technology and extensive application of harmonic control, type, number and proportion of non-linear loads are increasing rapidly, causing waveform distortion power system harmonics on impact of electric power equipment, power and communication lines and other users have been very serious. Harmonics can cause reactive power compensation equipment overcurrent and harmonic resonance amplification control, affect the safe operation of equipment. Accident affected by harmonics and equipment damage in common. Enterprises urgently need to address the impact on the grid harmonic source in order to ensure the normal operation of the compensation cabinet, not only to indicate the selected product model when ordering, but also indicate the load harmonic current content and related data. My company has a harmonic tester, test professionals to the scene, designed by computer simulation software. Over the years, our company experienced experts for many customers tailor-made a number of designs, accurate data analysis, the best solution, strong production strength, work great prestige Han of high-tech products as many enterprises ordering compensation cabinet the best choice. Low-voltage active power filter APF Technical Features: 1, the main circuit PWM control converter harmonic control principle, constitute a parallel active power filter; dual closed-loop control circuit tracking control technology, the use of high-speed large-capacity DSP computer chip, real-time, rapid detection of the load current harmonic components and reactive components, accurate current output compensation, filtering efficiency of greater than 90%, the response time of less than 10ms. 2, according to user load characteristics, optionally set the following three ways: a single filtered load harmonic current; single stepless compensation load reactive power, realize inductive, capacitive reactive bi?? compensation, so that the power factor is always 1. ? Filtered load harmonic current and reactive power compensation system. 3, by the system grid impedance change is small, and eliminate possible filter grid impedance parallel resonance occurs, to overcome the shortcomings of traditional passive LC filters. 4, a single device can be active power filter APF 2 times to 50 times for a broad spectrum of harmonic compensation, to overcome the traditional shortcomings of LC passive filter needs more single-tuned filter branch of the group. 5, the filtering effect is not affected by changes in grid frequency, to overcome the traditional LC filter frequency offset sensitive defects. 6, the harmonic current compensation object beyond the rated output current of the power active filter device does not appear active power filter device overload, to ensure the safe operation of equipment in real time. 7, the use of large-screen, high-definition, Chinese menu display color touch screen interface. Real-time display system voltage, current, harmonics, power factor and other electrical parameters harmonic control reactors, real-time display device operating parameters and historical events records, and can be 485 to communicate with the host computer. 8, a plurality of active power filter APF device can be used in parallel. 9, with the TSC dynamic reactive power compensation device used in combination, increase the reactive power compensation capacity and compensation accuracy; with TSF passive filter used in combination to increase the capacity of harmonic filter and filter precision.
