Enhancement of Power Quality in Distribution System Using D-STATCOM
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
Sensitive loads are greatly affected by power-quality (PQ) disturbances in the system. Power quality problems such as voltage sag and harmonic distortion along with reliability issues are some major concern and in this work the voltage distortion & reactive power issues are considered. Inverters based on Voltage Source Converters (VSC) are widely used as a basic component in custom power devices. These controllers produce voltage harmonics due to switching operation of power electronic converters. The proposed controller supplements the voltage-sag compensation control of the statcom. It does not require phaselocked loop and independently controls the magnitude and phase angle of the injected voltage for each phase. The proposed scheme have the following advantages such as limit the fault current , interrupt the fault current within two cycles, interrupt the fault current during arching fault and low dc link voltage. The circuit will be simulated using MATLAB.
