Improvement of energy efficiency through power quality by the compensation of harmonics with shunt active power filter

摘要

Energy efficiency means the efficient energy usage that is using less energy to provide the same service. Due to the penetration of advanced electronics in industrial and commercial applications many utility net works fall into the problem of inefficient operations. Though the advanced technologies are used to improve the productivity and improving the facility of the consumers, they will cause severe problems to the quality of the power through many factors. If the power quality problems are not taken care then the energy usage will be more for providing the same service. This paper presents the compensation technique of harmonics which is one of the major problems in maintaining the quality of the power. Here the shunt active power filter is used for harmonic compensation. The simulation results are given for the cases with and without power filter. The results are compared with the fuzzy output also.
