The Electrical power quality issue has attained considerable attention in last decade due to large penetration of power electronics based loads and microprocessor based controlled loads. Power quality has become an important topic of discussion and research, especially in a deregulated environment. As per IEEE 519 std. these parameters of power quality measurement are four in number, of which Total Harmonic Distortion is most widely used. The power quality disturbances decrease the efficiency of power system equipments such as generators. Therefore the issue of power quality is important to both the consumers and the utility of electric power. There are many facets of power quality disturbances and each has its own source and mitigation techniques. The power system faults are important source of power quality disturbances. This paper deals with power quality improvement in four bus system during faulty conditions using double tuned filter to reduce the effects of disturbances on the generators. The four bus system having two load and two generator buses is modeled in MATLAB/Simulink environment. A fault is created near the load bus and power quality disturbances are detected near the generator bus and improved using double tuned filter near the generator bus under study. The Matlab results show the performance of double tuned filter in improvement of power quality disturbances during faulty conditions.
