Abstract

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 sensitive loads. In
this paper, a new configuration for UPQC is presented.
Using the fundamental power flow analysis, it is shown that by
interchanging the position of series and parallel part of
UPQC, the total rating of compensator decreases. To acquire
more rating reduction, a new simple control algorithm is presented
for voltage compensation by injecting the reactive power. Using
numerical simulations, the performance of proposed and
conventional configurations is compared to show their operational
effectiveness and limitations in different loads and network
conditions.
