Achiever Study Plan ESE-2018: Power System Quiz 8

A power system has two synchronous generators having governor turbine characteristics as
P₁ = 50(50 - f)
P₂ = 100(51 - f)
where f represents the system frequency. Assuming a lossless operation of the complete power system, what is the system frequency for a total load of 800 MW?
