What is the exact procedure for finding regulation of a synchronous generator by direct loading? We have it in our syllabus..For full load,I know the initial steps till the rated voltage is obtained at rated speed on no load. But when the load is switched on, my book says: 1.Terminal voltage reduces, so it is brought back to rated value by changing excitation. 2. Speed reduces, so it is brought back to rated value by speeding up the prime mover. 3. Then the load is thrown off and further procedure is done. But in some books, step 2 is omitted. What is the right way?
