In this paper, a new reference waveform estimation

strategy based on an adaptive notch filter (ANF) is proposed

for unified power quality conditioner (UPQC). Two coupled

ANFs are used to generate the reference waveforms...

The cost of switching devices increases

exponentially by increasing their rating. Hence,

attractiveness of using unified power quality conditioners

(UPQC) is reduced when compensation to be carried out for

high power...

in case of any fault which leads to losing

the support of the main utility system. Active islanding detection methods (IDMs) are more

reliable than passive ones but they cause power quality issues. Harmonic current injection as an...

This paper discusses the design of a novel synchronous reference frame (SRF) method that can extract the reference compensating current for single-phase shunt active power filters (APFs). Unlike previous SRF studies, the ...

Ensuring power quality in power systems demands fast calculation of harmonics. In this paper, a recursive algebraic approach

to the calculation of current transformer (CT)-derived current signal frequency and harmonics is proposed...
