A generator has a synchronous reactance of 1.1pu and operateswith a busbar voltage of 1.1pu.
a) Draw the operating chart for the generator showing theboundaries corresponding to a peak stator current of 1.3pu, a peakinput power of 1.3pu, a maximum load angle of 60 degree and amaximum continuous field current of 2 pu, which produces 2puopen-circuit voltage.
b) Indicate on the chart the two operating points correspondingto output power of 1.1pu at the lowest permissible lagging andleading power factors. What are the values of the lagging andleading reactive power produced by the generator when operating atthese points?
c) If the generator is operated with a load angle of 45 degreeand rated power output, use the chart to find the correspondingvalues of field current, stator current and power factor.
