Improved desing of existing 210mw hydrogen and water cooled generators

In a synchronous machine rotor is the most important part. Excitation system size, earth fault levels, efficiency of the machine and reactive power required by the system depend upon the parameters of the rotor. This paper presents novel method of reducing the size of the excitation system thus improving the excitation system and reduced vulnerability to the earth faults, increasing efficiency, reducing the maintenance cost and less cost of the equipment, keeping the performance of the synchronous machine same. In this paper it is shown that by changing the rotor winding from 2 conductors in parallel to 1 conductor and increasing the number of turns, keeping the flux same how machine performance can be improved. This paper further brings out the energy saving or less energy consumption by generator itself eventually making the more capacity available of machine.
