Analysis Of The Role Of Harmonic Filters In Absorbing Major Harmonic Components

harmonic filter for generator absorbs the main harmonic components in the system while compensating for reactive power. It uses parallel passive LC groups or electrical harmonic filter to form a low-impedance path for specific harmonics, introduces the harmonic current into the filter circuit and injects equal-amplitude and opposite-phase compensation current into the bus. At the same time, it controls the output of adjustable reactive components through capacitors or inverters, and coordinates with grid-connected reactive power devices to adjust the capacitive and inductive characteristics of the system, so as to reduce harmonic propagation and improve power quality.
