Two synchronous generators supply a load of 5 MVA with a power factor of 0.8. No-load frequency of the first generator is fn1,1=52 Hz. Sp1
Two synchronous generators supply a load of 5 MVA with a power factor of 0.8. No-load frequency of the first generator is fn1,1=52 Hz. Sp1 is 2 MW/Hz and Spa is 1 MW/Hz. The system is operating at 50.5 Hz frequency. a. Find the no-load frequency of 2nd generator. Find the power sharing between 2 generators. Sketch the (P-f) graph. b. When loading level increases 10% Find the new system frequency and power sharing Sketch the (P-f) graph. c. To restore the frequency value of the first condition (a), the governor changes the no-load frequency of 1st generator. Find the new fnl, and the new power sharing between 2 generators. Sketch the (P-f) graph. d. When this 2-generator 1-load system is connected to an infinite bus system with 50 Hz frequency. Determine the new frequency of the whole system and calculate the new power sharing. Sketch the (P-f) graph. Two synchronous generators supply a load of 5 MVA with a power factor of 0.8.
