Figure P.8.36 shows two generators supplying in parallel a load of 2.8 MW at 0.8 pf lagging:
(a) At what frequency is the system operating and what is the load supplied by each generator?
(b) If the load is now increased by 1 MW, what will be the new frequency and the load sharing?
(c) In part (b) which should be the set point of G2 for the system frequency to be 50 Hz? What would be the load sharing now?
Consider a 15-bit, maximal-length PN code. It is generated by feeding back the last two stages of a fourstage shift register. Assuming a 1 1 1 1 initial state, find all the other possible states of the shift register (show details). What is the se..
A motor operated from a 480 V(rms), 60 Hz source has an output of 800 hp. The motor is 89% efficient and has a power factor of 69.5% lagging. What is the electrical input power in watts of the motor
What is the Difference Between Neutral, Ground and Earth?

An office building is billed based on the rate structure given in Table 5.3 (Energy charges is $0.0732/KWh and demand charge is $9 / mo-kw. As a money saving strategy, during the 21 days per month that the office is occupied
If i were to have a plane wave in free space with the following E field intensity: E = 15cos(ωt + 10πz + θ) in the y direction V/m and H at t=0 z=1.15m is 0.02 A/m how can I find the initial phase, θ
Two Bit Analog to Digital Converter - MATLAB Let x (t) = 0.8 cos(2*pi*t) + 0.15, 0≤ t ≤ 1, and zero otherwise, be the input to a two bit ADC converter. a.) For a sampling period Ts = 0.025 sec; determine and plot using MATLAB the sampled signal: x (n..
Consider the system shown in Figure 7-161. Draw a Bode diagram of the open-loop transfer function G(s). Determine the phase margin and gain margin.
Assume that the information rate out of the coder is equal to the information rate into the coder. What is the minimum time between bursts if your system is to operate properly?
A 150 MVA, 24 kV, 123% three-phase synchronous generator operates with an induced voltage that is twice the rated line-to-neutral voltage. Calculate the three-phase steady-state short-circuit current at the generator terminals.
Find how the volume of the tank varies as a function of time, if the inlet and outlet flow-rates vary. List the state variables.
