Enhancement Of Power Quality Under Different Fault Condictions And Harmonic Elimination By Using D-Statcom
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 10
Abstract
this paper mainly focuses on power quality with D-STATCOM Due to the non-standard voltage, frequency, and current at distribution side. In this paper the role of DSTATCOM (Distribution Static Compensator) are located at load side in electrical distribution system under normal operating and fault conditions is examine. Here DSTATCOM is used as a FACTS device which can compensate the reactive power. DSTATCOM is a voltage source converter; it can be used to compensate the voltage and make the system stable by compelling and generating reactive power. Here by using DSTATCOM to compensate the problems in distribution system such as voltage sag, voltage instability, in power systems with different fault conditions for LG, LLG, 3-hase, LCL filter The D-STATCOM injects a current into the system to mitigate the voltage sags. LCL Passive Filter was then added to DSTATCOM to improve harmonic distortion and low power factor in power faults. Here Simulink model and control system is designed in MATLAB/SIMULINK.
