ABSTRACT
Now-a-days with the improvement of technology, the demand for electric power is increasing at a growing rate. Many consumer appliances demand quality improvement in power constantly for their operation. The performance of the end user accessories dependent on the quality of power supplied. But the quality of power delivered to the consumer is affected by various factors. They are like frequency and voltage variations, faults, interruption etc. These power quality issues reduce the life time and efficiency of the equipment. The main affect caused by these problems is the presence of harmonics and interharmonics. This leads to the overheating of the equipment, insulation breakdown and over speeding of motors etc. The solution to run over these problems is to filter out these harmonics. For this purpose, there are many filters to snub harmonics but we use hybrid active filter which is combination of active series and shunt passive filter. This paper presents a control strategy for reduction of harmonics and simulation on MATLAB SIMULNK is present.
