How harmonic filters prevent distortions in networks with

Passive FiltersActive FiltersHybrid FiltersSelection CriteriaHarmonics Filters – IEEE 1531 OverviewA passive filter consists of a series circuit of reactors and capacitors. Harmonic currents generated by, for example, a frequency converter are shunted by this circuit designed to have low impedance at a given frequency compared with the rest of the network. The described function with a harmonics generator, impedance representing all other loads, a filter, and the medium voltage network are illustrated schematically in Figure 1. The equivalent circuit seen with the harmonics generator modeled as a harmonic current generator is shown in Figure 2. It includes the medium voltage (MV) network, and the voltage distortion is represented by a harmonic voltage generator. As the passive filters offer very low impedance at the resonance frequency, the corresponding harmonic current will flow in the circuit whatever its magnitude. Passive filters can get overloadedunder which condition they will switch off or be damaged. The overload may be caused by the presence of unforeseen harmonics on t...Get price
