How can I control the voltage on a Self Excited Generator without drastically reducing amperage?
The Generator is homebuilt based on a 3 phase 40hp Reliance Induction motor- Tag indicates 47 amps @460 Volt @1750 RPM.Technical:
Generator is wired in WYE format.
Generator is spun to 1800 RPM and generates power at 60 HZ on all tests.
System has a capacitor bank of 3 - 100 uf Capacitors wired in series.
Capacitor Layout: L1 to Cap 1 & 2, L2 to Cap 1 & 3, and L3 to Cap 2 & 3
Output Voltage: In excess of 350 Volts per Leg 600+ across any 2 Poles
Output Amperage: 35+ Amps per LegI noted on a Coleman 5k generator I had, that the voltage went over 330 volts and they replaced the regulator and it was back to 220 Volt output. I realize the other genset had exciter coils so the systems are very different but, that leads me to believe there still should be a way to control the high voltage - short of cutting back the capacitor values. I ended up going by voltage and at 280 Volts allowed only 40 uf caps to be used with abyssimal output of 11 amps (per Leg).So, is there a regulator adaptable to this beast or a method of wiring the system to make it work more efficiently. This is now an 18 month long project and shows promise - but the High Voltage issue seems unending.PS> I have found papers written by Dr Bhim Singh of New Delhi on proposals for an SEIG (Self Excited Induction Generator) Regulator, however I have not been able to find anything commercially built.
