[3 marks]List practical aspects for describing the reactive power flow problem in voltage collapse.
[4 marks]A 100 MVA synchronous generator operates on full load at frequency of 50 Hz. The load is suddenly reduced to 50 MW. Due to time lag in governor system, the steam valve begins to close after 0.4 seconds. Determine the change in frequency that occurs in this time.
