Hi,
I have a wind turbine which runs most of the time below 150 volts, connected to a windmaster inverter, which is grid tied. The windmaster is limited to 150 volts, so I have a device which shorts out the turbine when 150 volts is reached - this activates the break to slow the turbine.
I was thinking of another solution.
Voltage dividers exist, I am using one to log the voltage generated by dividing the voltage by 10 because my data logger was designed for a 24 volt system, not 150 volts.
How easy would it be to build a device that when the voltage reaches 145 volts, it 'adds' in a circuit that acts as a voltage divider, taking off say 30 volts from the circut, so that the break device does not activate. If the wind speed ever got to the point when it procuced 180 volts, then the break device would get its 150 volts and activate the wind turbine break.
Such a device could help produce more power, as on the few occasions the turbine produces over 150 volts, it takes up to 3 minutes for every thing to reset and start generating power. So a gust of wind taking the voltage from a steady 120volts to a few seconds of 160 volts would loose a significant amount of power in relation to the period of the gust.
