Majority of the industrial and commercial loads such as power converters, variable frequency drives, air conditioners, escalators, elevators, etc. incorporate a large number of power electronic devices. These loads introduce dynamic harmonic current, imbalance in the current and varying reactive power demand in the three phase AC mains supply. This paper presents a comparison of four shunt active filtering algorithms. The control algorithms are simulated and analyzed using the MATLAB/ Simulink software under different operating conditions.

Fan is one of the unavoidable electronic equipment in everyday life. The presence of a fan in a house, office or school is not considered as a luxury on the other hand it is included in the basic requirement. Here the facility of ordinary fan is increased by making it controlled by a remote. In a remote controlled table fan, a remote is used to regulate the speed of fan and to adjust its position. Radio Frequency (RF) remote can be used for controlling speed and to swing the fan to a desired direction. Using this system, changing the speed of the fan and adjusting the direction from couch or bed or even outside the room is possible. The remote is used for controlling the speed of the fan in three different levels. This innovation finds its use mainly to help old age people who cannot walk in order to control the speed of fan. Remote controlled fan with infrared remotes are already implemented but, here radio frequency remotes are introduced so that high range is obtained as compared with infrared remote and presence of obstacles does not affect its working as in case of infrared remote.

This paper presents a photovoltaic (PV) integrated unified power conditioner (UPC) system that provides power quality enhancement as well as real power sharing. The shunt inverter of the PV integrated UPC system provides compensation for the harmonics present in the source current and reactive power while the series inverter compensates for voltage harmonics, voltage sags and swells. A novel control algorithm is used to operate the inverters of unified power conditioner integrated with photovoltaic generation scheme to improve the power quality at the Point of Common Coupling (PCC). The control scheme for PV integrated UPC is verified using MATLAB/ Simulink and validated experimentally using laboratory prototype.

Power electronic controller based power system equipment are widely used in industrial, commercial and residential sectors. These controllers help in energy saving, but they introduce different power quality issues such as harmonic distortions in current and voltage, voltage sag/swell etc. These power quality issues cause malfunctioning of associated circuits. This paper presents an adaptive shunt hybrid filter where voltage support for DC link capacitor is provided by solar photovoltaic source which improves the power quality by eliminating current harmonics, and improving the power factor. With the help of suitable control algorithm, the filter achieves capability of real power pumping to the grid in addition to harmonic and reactive compensation. The simulation results are carried out with three phase non-linear loads under balanced and/or unbalanced source/load conditions. The results obtained are satisfactory which depicts the effectiveness of the control algorithm and improvement in the power quality with Solar Photo Voltaic integration.
