Power quality estimation, analysis and improvement for uninterrupted power supply

With increasing use of power electronics, the amount of harmonics and other power quality problems are increasing in the system. Because of this power quality has been an important topic in the area of research. There are a number of reliability and economic issues with respect to electronic equipment. In such a scenario it is important to study the causes, effects and mitigation technologies for power quality. This problem can be approached by using a DAQ system to gather data on the system and then analyse the collected data. Once power quality analysis is completed appropriate mitigation technique is simulated then implemented. Results from this work demonstrates how to estimate the power quality of a given system and the steps involved in mitigating those issues. The conclusion can be drawn from this work that each mitigation technique has its limitation and they must be kept in mind when designing a system to mitigate power quality issues.
