Power quality measurements at an automobile factory. Conclusion

The value of power quality (PQ) is decided by economic consequences of a PQ deficiency. For example, the cost of damage caused by an outage can range from millions of euros for a small number of consumers, those with highly automated production plants, like actual automobile factories to nearly nothing for the vast majority. With this work, the intention is to complete a previous, sufficiently representative, study based on data acquisition and measurements of harmonics inside PSA PEUGEOT CITROEN, an automobile factory located in Vigo (Spain) that prepare 2.162 cars per day and has about 9.000 employees. The idea is take the harmonic measurement in the cut line No 8 (7E) and propose for harmonic mitigation an active power filter centralized for this line controlled by a microprocessor.
