I would like to follow up on a discussion of under what conditions an anti-islanding compliant inverter would have problems with the utility power quality and off grid inverters would have with generator-derived power quality. I think that Bill Brooks pointed to a document a while ago about specific transient events, and we all know (or should know) the +/- 10% VAC and +/- 0.1 Hz requirements. Bill would you be so kind as to point us there again?
What I would like to understand is the following: Is there a power quality analyzer (e.g. Fluke 430 Series II) out there can asses power quality and predict compatibility with the various grid-tied and off grid inverters? As far as off-grid inverters are concerned, what I imagine is a follows: -- Fire up a generator (e.g. Honda Eu3000iS), load it down with a reasonable resistive load (e.g. 1,500 kW), and look at VAC, freq, harmonic distortion, transient events -- and come up with a way to assess whether or not an off-grid inverter would work with the generator As far as grid-tied is concerned, monitor utility power and provide the same answer for grid-tied inverter. - Peter Parrish Peter T.
