Description: PECTRUM of the input current drawn by the electric
drive from the network is affected by the used type of the
input rectifier. In the case of the diode rectifier, the number of
its pulses is decisive. Standard AC adjustable speed drives
utilize the input three phase six-pulse diode rectifier for the
AC-DC conversion. These drives generate harmonics into the
network, so the drawn current is not harmonic, but nonharmonic
with a high level of distortion if no harmonic filter
is used. The input current total harmonic distortion is
calculated from the formula Platform: |

Description: This paper deals with the design and implementation of
a multilevel voltage source converter based static synchronous
compensator (STATCOM) employing an effective modulation
control technique simulated in a MATLAB Simulink
environment. The main objective of this paper is to maintain the
voltage stability by compensating the reactive power in the power
system. Hence, a new efficient control strategy is proposed, in
order to reduce the voltage fluctuations like sag and swell
conditions and also to isolate current and voltage harmonics in
the transmission system. The multilevel STATCOM which can be
used at the point of common coupling (PC C), for improving
power quality is modelled and simulated using proposed control
strategy and the performance is compared by applying it to an
llOkv line with and without STATCOM. Relative Harmonic
analysis is also discussed in this paper based on the total
harmonic distortion (THD) calculations. Platform: |

Description: The active power filters have gained much more attention because of its excellent performance to mitigate the harmonic and reactive power issues. A shunt active power filter with Instantaneous active and reactive power theory (P-Q theory) has been proposed for its performance and ability to compensate the harmonics and reactive power.. It has been investigated through simulations that even under unbalanced and distorted conditions of AC distribution supply voltage and unbalanced loading, shunt active filter is able to produce the unity power factor and mitigate the Total Harmonic Distortion (THD) specified by power quality standards. Matlab/Simulink is used as a simulation tool for analysing. Platform: |
