what are the different ways to vary the load angle of an alternator? what i suppose there are two ways by which we can vary load angle:

1) by varying the field excitation

2) by varying the input mechanical power to the alternator?

So i wanted to know whether i m correct in my assumption or not
Is there any other way to change the load angle value?

Load or torque angle can be varied by either changing the exciter field current or by the current flow in the stator winding and speed of rotation

 

Try this (obtained by typing 'generator load angle' (without the quotes) into Google):
