Hi Polarman! 1. I've not decided wich generator to buy yet, but I think it will be an 3 phase self magneting. So I don't have to regulate the voltage. 2. pelton turbine 3. Yes there is a flywheel 4. I need to adjust 100% of the total load The turbine is an old pelton with a very slow gravity regulator, and it will not bee good enough even with the flywheel when on isolated grid. The reason I can not deliver the unused power to the grid is because it is nearly 15km away. My idea on solving this is to measure the load in all three phases and use this to decide when in the half period to use the triac or tyristor. Then I can also avoid unbalanced load. Another way to do it is to measure the speed of the generator with a tachometer, but this will not adjust eventually unballanced load. Do you have any meanings on what configuration of tyristors/triacs and resistors to use. I found a webpage about this, but I'm not sure what to use. http://www.ccipower.com/support/load.php

Hi! I have a hydropower 3 phase 55KVA generator with no regulation. What I want to make is an electronic load that holds the load constant. The load must adjust automaticaly when I for example turn on my oven so the total load on the generator allways is constant. I've been thinking of using triacs or tyristors like you do in a dimmer, and burn the energy in large resistor. And controll it with a PLC or something like that. But how will this affect the output? Will the sine wave still bee perfect? Is there anyone having any good ideas? Thanks in advance. Volzon
