Handbook of Power Quality (Free PDF)

File Size: 8.15 Mb

Power quality (PQ) issues are relatively new: years ago this was a problem concerning only power stations and arc furnace engineers. It is only recently that the electrical engineering community has had to deal with the analysis, diagnosis and solution of PQ problems, even if it has not become a major topic in the industry. Professionals are being confronted with PQ issues on a daily basis, yet only the latest generation of engineers has been trained to face and solve these issues.

The main reason is probably due to the fact that PQ is a complex area covering many different topics. This is also something that makes a comprehensive book difficult – each PQ topic can warrant an entire book, but time is more and more a constraint.

If PQ issues applied to utility networks are relatively new, the same concepts applied to customer installations and equipment have attracted the attention of the electrical world only in really recent times.

The problems related to PQ are often difficult to solve, and may allow different solutions, so the choice is not always simple for those engineers and professionals who are not trained in PQ. The optimal solution to a PQ problem is usually a mix of solutions for a specific situation. In such a situation, it is necessary to identify that problem and propose different solutions to allow the technicians to make the optimal choice.

Evaluation of solutions is probably the key element in PQ problem solving, chiefly for economic reasons. Actually, some solutions require higher investments, and thus the necessary management approval, but managers usually lack the knowledge to evaluate the problems properly.

For these reasons, in 2000 a group of academics and industrialists launched a cultural programme co-founded by the European Commission and fully dedicated to PQ from the perspective of not just power suppliers but electricity users too. Seven years later this program has more than 100 partners around the world and numerous sub-projects focused on specific issues related to PQ. It was at one of these, LPQIves (LPQI Vocational Educational System), during the Berlin meeting in April 2005, that the idea for this book was born.
