As i have read on the internet that during synchronization the prime mover connected to the turbine produces a little over than required power to keep the turbine cum generator assembly moving at the synchronous speed that is regulated by the grid frequency (In india its 50Hz). As the generator is synchronized, the speed of the turbine cum generator will remain equal to 3000 RPM (As per frequency of 50Hz). Now if more steam is admitted to the turbine, then the torque produced by the turbine will increase but the speed of the turbine cum generator assembly cannot increase beyond synchronous speed, so that increased torque gets converted into amps. Now my question is, i am not able to understand the physics behind how this conversion of torque into amps takes place at fundamental level. So kindly help me in this.
