Power quality problems mitigation using dynamic voltage restorer in Egypt thermal research reactor (ETRR-2)‎

Abstract EN

Egypt thermal research reactor (ETRR-2) was subjected to several Power Quality Problems such as voltage sags/swells, harmonics distortion, and short interruption.

ETRR-2 encompasses a wide range of loads which are very sensitive to voltage variations and this leads to several unplanned shutdowns of the reactor due to trigger of the Reactor Protection System (RPS).

The Dynamic Voltage Restorer (DVR) has recently been introduced to protect sensitive loads from voltage sags and other voltage disturbances.

It is considered as one of the most efficient and effective solution.

Its appeal includes smaller size and fast dynamic response to the disturbance.

This paper describes a proposal of a DVR to improve power quality in ETRR-2 electrical distribution systems .

The control of the compensation voltage is based on d-q-o algorithm.

Simulation is carried out by Matlab/Simulink to verify the performance of the proposed method.
