37345 - Quality of Electrical Energy T

Learning outcomes

Objective of the course is to supply base elements for study and problem analysis relevant to Power Quality (PQ), that are increasingly becoming of interest at the present time, in particular because of the progressive introduction of power electronics devices in the manufacturing activities and civil uses, and as a result of the Free Electrical Market in Italy.

Course contents

1) Power Quality (PQ) Disturbances:

 I) interruptions;

II) voltage sags;

III) transients;

IV) harmonics (theoretical treatment, passive filters, active filters);

V) flicker (arc furnaces, flicker-meter, SVC).

2) Analyses of the main standards and regulatory dispositions that take care of PQ (technical deliberations of the AEEG and Standards CEI EN 50 160 and CEI EN 61000-2-4).

3) Fundamentals about the Electric Energy Market.

4) Practical lessons in classroom and/or laboratory.
