Brushless excitation regulator system for generator

TWL-SD type brushless excitation regulator is a multi functional high performance computer controlled AVR, it’s use for voltage 400V/6300V, capacity below 1000KW brushless excitation synchronous generator.

Main function of brushless excitation regulator:

keep the voltage of the generator stable,
restore the normal voltage of generator when the load changes suddenly, balance the no-power of generator under parallel operation, monitor network voltage,
reactive voltage and power coefficient to keep generator stable under net operation,
make the voltage of generator decreases with the frequency when generator is operated under low frequency.

The TWL-SD type brushless excitation regulator is a multi functional high performance computer controlled AVR, it’s use for voltage 400V/6300V, capacity below 1000KW brushless excitation synchronous generator.
