I want to be able to move the windmill I am designing out of the wind when the power output is to much (high wind scenario). To do this I need to measure the output of the power. To set everything up I need to be able to select my equipment for max current/voltage/power/etc. The generator I am planning to use for now is this generator. The max output from the graph seems to be about 800V DC rectified. At max RPM however the max OC DC rectified voltage is about 675V. Some calculations later I figure about 500VAC LL output @ 675V DC rectified. This is assuming a balanced load and current flow but there is none at the open-circuit point. I am assuming the voltage will be lower under load. Being under load all the time (diversion unit in place) will allow me to "safely" use equipment rated for typical 3-phase AC voltage of 480V?
Also for testing and maintenance since this is a prototype I wanted a shut off switch to be able to work on the control section. I am thinking the best way is to have a 3 phase 480V knife switch (lock out tag out method) in series between the diverting modular and the control modular. Any other suggestions?
