Abstract

The industries such as steel plants, traction railway systems and other major industries use arc welding, furnace, and dynamic motor loads. These loads are in particular non-linear and distort voltage or current, or both waveforms. Such distorting waveforms in the source leads will damage all the sensitive loads like computers, lighting loads, and other metering devices. Hence compensation of these harmonics plays a vital role. So, in this paper, a shunt power quality conditioner called DSTACOM is used for compensation of current harmonics produced due to diode rectified based load. The control scheme adopted is an active power controller based on the current hysteresis band. To improve the performance with conventional PI controller, comparison is made with fast acting FUZZY and ANFIS-PID (AFPID) controllers are made. It is found that dc link voltage is almost constant, source and load voltage and current waveforms are improved with better THD values. The results are observed in MATLAB/ SIMULINK environment and found the current is compensated effectively with AFPID than FUZZY and PI controller based DSTATCOM.
