Synchronous generator & Generating units

Question 1:

Three generating units operating in parallel at 60 Hz have rating of 300, 500, and 600    MW and have speed-droop characteristics of 5, 4, and 3%, respectively. Due to a change in load, an increase in system frequency of 0.4 Hz is experienced before any supplementary control action occurs. Determine the amount of the change in system load and also the amount of the change in generation of each unit to absorb the load changes.

Question 2:

A synchronous generator, capable of developing 500MW of power operates at a power angle of 8°. Using equal area criteria, determine by how much the input shaft power can be increased suddenly without loss of stability.
