The wind generator that I am trying to regulate is a 3-phase 1000 watt 120 volt unit. The generator is used to power a submersible pump. The problem is that the generator produces more power that the pump needs when the wind gets up above 15 mph or so. If the voltage rises above 300 volts the pumps electronics goes out ruining the pump motor. I installed a wind switch that controls a relay when the wind is greater than 15 mph that adds a 1000 watts of load to the line to help control the voltage.
What I think is needed is a PWM regulator that could sense when the voltage rises above 120 volts and begain to pulse the additional load to control the voltage. Is there such a device already and if so what is it called? Any other suggestions would be appreciated.
