The synchronous reactance of a cylindrical rotor machine is 1.2 p.u. The machine is connected to an infinite bus whose voltage is 1 p.u. through an external reactance of 0.3 p.u. For a power output of 0.7 p.u., the power angle is found to be 30°.A. Find the excitation voltage Ef and the pullout power Pmax .B. For the same power output the power angle is to be reduced to 25°.Find the value of the reduced external reactance connecting the machine to the bus to achieve this.
