| Abstract: | An emulator is described herein, wherein the emulator is configured to
emulate a rotary energy generator. The rotary energy generator can be one
of a wind turbine, a diesel engine, or a hydrokinetic generator. The
emulator includes an electromechanical motor that is mechanically linked
to a generator. A motor drive is electrically coupled to the
electromechanical motor, and controls torque at a rotor of the
electromechanical motor. Electromagnetic torque produced by the generator
is estimated, and the motor drive is controlled based upon the estimated
generator torque. |
