This paper presents a three phase shunt Active Power Filter (APF) for power quality
improvements in terms of harmonics compensation. The compensation process is based on
measure non-liner load currents and Active Filter currents, and then extract t
he references
from measured currents. Measured currents are then transferred from abc frame to d-q
reference frame. A Synchronous Proportional Integral controller (Synchronous PI
controller) is used. The control signals then drive the Pulse Width Modulation (PWM)
routine, where its output controls the Voltage Source Inverter (VSI) switching devices. The
performance of the Active Filter and the Synchronous PI controller is validated though the
simulink results in MATLAB environment.
تعمل التوافقيات على إنقاص مردود التجهيزات الكهربائية و تشويه حسن أدائها ، كما تعمل
على رفع درجة حرارة الأجهزة و المعدات المستخدمة في نظم الطاقة الكهربائية ( محركات،

In this paper, we have suggested the STATCOM
(STATic synchronous COMpensator) to connect PV-solar (or
wind) frame to the power system for the Hassia industrial city
which we chose as a case study. This frame will provide the city
with the required power, improve the power quality and inject
the redundant to the power system.
