چکیده
The typical loads in the commercial buildings comprise of many single phase and three phase loads which includes non-linear loads. These loads are highly sensitive for any input variations in voltage. The performance of the electrical equipment gets worsened if they are supplied with polluted or distorted voltage. This paper presents modeling and analysis of custom power devices. SAPF based UPQC to take power quality problems. Series active power filter is implemented for harmonic and voltage distribution compensation of the three phase three wire distribution system. The custom power devices are realized by the hysteresis control based SAPF .The SAPF can be realized by three phase three leg VSI .A dynamic model of SAPF is developed in the MATLAB/SIMULINK environment and the simulation results are presented to show the effectiveness of proposed SAPF custom power device for a three phase three wire distribution system.
