Active filters are called active filters. As the name suggests, this device needs to provide power (to compensate for main circuit harmonics). Its application can overcome the shortcomings of traditional harmonic suppression and reactive power compensation methods (traditional only fixed compensation). Realize dynamic tracking compensation, which can compensate for harmonics and reactive power.
The instantaneous reactive power theory of three-phase circuits is the main basic theory for the development of APF; APF has parallel type and series type, the former is used more; parallel active filters are mainly used to process current harmonics, and series active filters are mainly used to process Problems caused by voltage harmonics. Compared with passive filters, active filters have good processing effects. It can filter multiple and high-order harmonics at the same time without causing resonance, but the price is relatively high!
The efficiency of the active filter is 97.2%, which is 95% more efficient than the active filter. The annual energy saving is about 6500kwh. Based on thermal design and structural optimization of accurate models, topology-enhanced control algorithms are more efficient.
The active filter is only 1/6 of the size of similar mainstream brands, takes up less space, and can adapt to installation innovations in different working conditions. Wall-mounted or rack-mounted installations use less raw materials to protect the environment. Full-featured monitoring system that automatically detects unbalanced loads of the capacitive reactive power compensation system and suppresses system resonance.
