| Abstract |
Susceptibility of adjustable speed drives (ASD)
against voltage dips it has been a red-hot issue in the last years.
European standards concerning electromagnetic compatibility in
the section of voltage dips do not allow characterization of ASD
performance when a voltage dip occurs. Papers published about
this subject are focused on the theoretical study of the effects of
dips on ASD and alternative methods for testing voltage dip
immunity of this equipment. But in the former, only undervoltage
trip has been usually taken into account; and, in the latter, the
criterion used to decide when the ASD fails is not suitable in all
cases. Firstly this paper will briefly analyze why an ASD trips
when there is a voltage dip. Secondly a test will be proposed with
two main goals: (a) to offer a novel, simplified and affordable test
protocol, and (b) to achieve test results useful for ASD users. To
accomplish this second goal, energetic immunity and control
immunity will be introduced to take into account process
necessities where ASD is integrated. |
