Correction of Power Quality Issues in Distribution System Using DSTATCOM with SSULMS Control Algorithm
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2014, Vol 1, Issue 9
Abstract
Power quality disturbances is the major concern in the distribution system, that leads to tripping and malfunction of sensitive equipments in distribution system. A Distribution Static Synchronous Compensator (DSTATCOM) can be used to mitigate the power quality issues by injecting/absorbing real and reactive power to the point of connection(PCC). This study presents how the DSTATCOM used to compensate the voltage sag, voltage swell, power factor problems and harmonics and thus to improve the distribution system performances by using an advanced control based on step size updating LMS algorithm. A 6 pulse Voltage Source Inverter based D-STATCOM with proposed control algorithms are designed and graphic based model of the same is developed using MATLAB/Simulink simulation program. The results obtained in different cases are analysed. Based on this analysis the capability of DSTATCOM to mitigate the power quality disturbances using SSULMS algorithm under various circumstances is validated
