COURSE PLAN - PART II COURSE OVERVIEW

Energy is \,ital for all living beings on earth. Modern lifestyle has increased its importance because of its faster transport faster communication and faster manufacuring processes. All these lead to an increase in enerID demand for all those modern systems. There have been significant developments and advances in the field of power generation systems. computer applications on energy audit and management ene\ ironment audit and managc111cnt .. :id human development. This course is for benefit of students of engineering because upon completion of the course. they get acquinted \\,ith different 1) pes of power generation system'>. Students will be taught about the worl-ing principle of different types of power generation systems. <:,tudcnts will realize the ncce!>!>ity for interconnected operation of different pO\\er .,tat ions.
