Power Angle Characteristics of Synchronous Generator

       We have seen previously,

The relation between Pand δ is known as power angle characteristics of the machine. It is shown in the Fig. 1.
Fig. 1  Power Angle Characteristics

       The maximum power occurs at δ = 90o . Beyond this point the machine falls out of step and loses synchronism. The machine can be taken up to Pi max  only by gradually increasing the load. This is known as the steady state stability limit of the machine. The is normally operated at δ much less than 90o.
