PROJECT TITLE :

DSTATCOM supported induction generator for improving power quality - 2016

ABSTRACT:

This paper presents an implementation of sliding mode controller (SMC) along with a proportional and integral (PI) controller for a DSTATCOM (Distribution STATic COMpensator) for improving current induced power quality issues and voltage regulation of three-section self-excited induction generator (SEIG). The use of SMC for regulating the DC link voltage of DSTATCOM offers varied benefits like reduction in number of sensors for estimating reference currents and also the stable DC link voltage throughout transient conditions. The use of PI controller for terminal voltage management provides the error free voltage regulation in steady state conditions. The voltage regulation feature of DSTATCOM offers the benefits of single purpose voltage operation at the generator terminals with the reactive power compensation that avoids the saturation in the generator. Different offered blessings are balanced generator currents under any loading condition, harmonic currents mitigation, stable DC link voltage and the reduced variety of sensors. The SMC algorithm is successfully implemented on a DSTATCOM employed with a 3-section SEIG feeding single part or 3 section masses. The performance of the proposed control algorithm is found satisfactory for voltage regulation and mitigation of power quality issues like reactive power compensation, harmonics elimination, and load balancing underneath nonlinear/linear loads.
