Three physically identical synchronous generators are operating in parallel. They are all rated for a full load of 3 MW at 0.8 PF lagging. The no-load frequency of generator A is 61.2 Hz, and its speed droop is 3.4 percent. The no-load frequency of generator B is 61.5 Hz, and its speed droop is 3 percent. The no- load frequency of generator C is 60.5 Hz, and its speed droop is 2.6 percent. (a) If a total load consisting of...

A microgrid operating in islanding mode is shown in figure 5. The two generators are rated at 50MVA and 70 MVA. At first, the generators supply power at 50Hz to Loads A, B, and C Under these conditions, Loads A, B and C are each drawing 20MW, while each generator supplies 30MW Later, the fourth load, Load D, is switched on, drawing 30MW. The droop controllers for the generators are set so that each generator supplies the extra power in...
