Electrical Project Report on Power Quality Analysis

This is Electrical Engineering final year project on "Power Quality Analysis" using Fluke 435 power quality analyzer. Power quality downside is a happening manifested as a nonstandard voltage, current, or frequency that ends up in a failure or misoperation of user equipment, utility distribution networks, sensitive industrial hundreds and important losses. With the restructuring of power systems and shifting trend towards distributed and spread generation, the difficulty of power quality goes to require newer dimensions. This project provides an overview of electric power quality with special emphasis on power quality problems and its adverse impacts on utilities and customers. You can also subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.

In developing countries like Asian country, wherever the variation of power frequency and lots of such alternative determinants of power quality area unit themselves a significant question, it's terribly very important to require positive steps during this direction. This project identifies the outstanding issues during this space.


Power quality is crucial for the sleek functioning of the economic method. As industries expand, utilities become additional interconnected and usage of electrical instrumentation will increase, power quality is jeopardized. The standard of power within the grid is severely tormented by the presence of harmonics. This harmonics adversely affects the facility system performance. A number of the results area unit heating of metal elements, noise in motors, low potency in motors, etc. the results made by the harmonics area unit reduced by adopting some corrective measures.

Quality can be defined in many ways. Stable voltages and undistorted waveforms are two characteristics, which are very desirable in power systems. Thus while not having a strict basis of measurement, terms like "Poor Power Quality" generally mean there is sufficient deviation from norms in the power supply to cause equipment misoperation or pre-mature failure.

In this project on "power quality analysis", it is often useful to think of power quality as a compatibility problem: is the equipment connected to the grid compatible with the events on the grid, and is the power delivered by the grid, including the events, compatible with the equipment that is connected? Compatibility problems always have at least two solutions: in this case, either clean up the power, or make the equipment tougher.

Conclusion: A survey of harmonic content in the voltage and current waveforms in the single-phase rectifier with a resistive, inductive and capacitive load connected to it is being conducted with an objective to know the existing level of harmonic distortion. It is observed that the voltage distortion is found to be around 1.7 % and the current distortion is found to be around 50.6% with a power factor of 0.8 in case of rectifier with resistive load and the voltage distortion is found to be around 1.5 % and the current distortion is found to be around 95.2% with a power factor of 0.24.
