What is contingency Analysis?
[3 marks]Discuss the block diagram of load frequency control for Isolated system.
[4 marks]The Gen-1 and Gen-2 is rated for 100 MW and 300 MW, respectively. The governor speed regulation of Gen-1 and Gen-2 is of the order of 4.0 and 6.0 percent from no-load to full-load, respectively. They are operating in parallel and share a load of 400 MW. Assuming free governor action and no-load operating frequency of generator is 50 Hz. determine the load shared by each unit.What will be the system frequency at that load?
