A 480-V, 250-kVA, 0.8-PF-lagging, two-pole, three-phase, 60-Hz synchronous generator's prime mover has a no-load speed of 3650 r/min and a full-load speed of 3570 r/min. It is operating in parallel with a 480-V, 250-kVA, 0.85-PF-lagging, four-pole 60-Hz synchronous generator whose prime mover has a noload speed of 1800 r/min and a full-load speed of 1780 r/min. The loads supplied by the two generators consist of 300 kW at 0.8 PF lagging.
(a) Calculate the speed droops of generator 1 and generator 2.
(b) Find the operating frequency of the power system.
(c) Find the power being supplied by each of the generators in this system.
(d) What must the generator's operators do to adjust the operating frequency to 60 Hz?
(e) If the current line voltage is 460 V, what must the generator's operators do to correct for the low terminal voltage?

apply the MACDtrading strategy to the closing price of QQQQ for the period from February 1, 2005 through September 1, 2005. What is the netgain over the time period assuming that your first order must be abuy and your last order a sell
Electric field due to conducting shell. A spherical shell of radius a is charged with a uniform surface charge density p,. Find the electric field intensity inside and outside the spherical shell.
A CG amplifier when fed with a signal source having Rsig = 200 ohms is found to have an overall voltage gain of 10V/V. When a 200 ohm resistance is added in series with the signal generator the overall voltage gain decreased to 8V/V.
Consider the power amplifier model above. Choose a sample time T and obtain the pulse transfer function G (z). Use root locus plot with 'grid' to design a static compensator for ζ = 0.7. Plot the step response.
