Design and performance evaluation of a hybrid active power filter controller
Leopold Herman, Klemen Knez, Boštjan Blažič
Izvirni znanstveni članek
Oznake: hibridni filter;filtriranje harmonikov;dušenje resonanc;povratna vezava stanja;izboljšanje kakovosti električne energije;hybrid active power filters;harmonic filtering;resonance damping;state-feedback control;power quality improvement;
This paper introduces a novel hybrid filter topology that combines passive and active components to enhance harmonic filtering and resonance damping in electrical power systems. The design integrates a three-phase two-level voltage-source converter with a double-tuned passive filter in parallel, sig ...

Active filter reference calculations based on customers' current harmonic emissions
Aljaž Špelko, Boštjan Blažič, Igor Papič, Leopold Herman
Izvirni znanstveni članek
Oznake: referenca aktivnega filtra;emisije harmonikov;kakovost električne energije;referenčne impedance;active filter reference;harmonic emission;power quality;reference impedances;
This paper deals with harmonics compensation in industrial and distribution networks using an active filter (AcF). When defining the AcF’s reference current, it is important to properly consider the network background harmonic distortion. Within this paper, we propose an AcF reference current calcul ...

Harmonic resonance identification and mitigation in power system using modal analysis
Jure Lokar, Janja Dolenc, Boštjan Blažič, Leopold Herman
Izvirni znanstveni članek
Oznake: frekvenčna občutljivost;zamik resonančne frekvence;resonanca;industrijska omrežja;modalna analiza;kakovost napetosti;frequency sensitivity;frequency shift;harmonic resonance;industrial networks;modal analysis;power quality;
Due to a rising share of power electronic devices in power networks and the consequent rise in harmonic distortion, impedance resonances are an important issue. Nowadays, the frequency scan method is used for resonance phenomena identification and analysis. The main disadvantage of the method is its ...
