While extensive use of industrial automation rectifiers, inverters, frequency furnace and automatic welding equipment generates a large number of harmonics, making the system voltage and current waveform distortion, resulting in deterioration of power quality, harmonics of the grid has become the most important risk hazard. In order to filter out the harmonics on power systems, harmonic filter using reactive power compensation device is one of the best ways. The company's application of advanced power electronics technology and intelligent control technology, scientific, economic and effective means to not only solve the technical conditions in the harmonic compensation of shunt capacitor switching problem, but also the actual situation and requirements of the user to suppress or governance harmonic, clean power supply network and improve the power factor. Therefore, the product is low-harmonic high-tech areas of governance, the most technologically advanced and reliable new products. Structural performance: an important component of this device are: monitoring unit, silicon semiconductor modules, filter capacitor, filter reactors, circuit breakers, control and protection systems, cabinets, etc. The capacity of the capacitor device is based on: fundamental frequency, the system needs reactive power compensation is determined; the LC circuit of the inductance value is chosen based on: the harmonic frequencies can produce series resonance with capacitor, the device in the form of the harmonic frequencies are very low impedance (near zero), so most of the harmonic currents flowing into the device without the flow of power supply system. Improve the supply system harmonic voltage distortion. While the installation of shunt capacitor sets the device for fast dynamic reactive power compensation. To meet the needs of rapidly changing loads. The filter compensation device using a single tuned LC passive filter compensation, harmonic condition for the user site design. A typical filter to filter harmonic compensation devices are generally divided into: 3 (150Hz), 5 second (250Hz), 7 second (350Hz), 11 second (550Hz), 13 second (650Hz), and so on. The device and the load is connected in parallel. Its characteristics are:
