A 3-phase synchronous generator feeds into a 22 kV grid. It has a synchronous reactance of 8 Ω/ phase and is delivering 12 MW and 6 MVAR to the system. Determine:
(a) the phase angle of the current
(b) the power angle
(c) the generated emf.
A block error detecting code has a minimum distance of three. How many errors can this code detect and how many can it correct
A 78oham lossless planar line was designed but did not meet a requirement. What fraction of the widths of the strip should be added or removed to get the characteristic impedance of 75oham
Write a computer program to evaluate the coefficients of the complex exponential Fourier series of a signal by using the FFT.
Write a script that numerically calculates the slopes for the function y = ex. Use x-values that range from 0 to 10 in increments of 0.1. Using these slopes, calculate the equation of a line that is tangent to the function at x = 8.3.
A wind turbine with a gearbox ratio of 200 produces electric energy when the generator speed is at least 910 rpm. The length of each blade is 5m. The turbine has a variable tip speed ratio (TSR). At a wind speed of 10m/s, compute the minimum TSR o..
Sketch or use the computer program of your choice to produce a plot of the impedance magnitude versus angular frequency for a 20-mH inductance in series with a 50-μF capacitance. Allow ω to range from zero to 2000 rad/s and the vertical axis to ra..
a nolinear distortion results in the generation of frequencies in the output that are not present in the input. if
Suppose that a public address system emits sound uniformly in all directions and that there are no reflections. The intensity at a location 26 m away from the sound source is 3.0 × 10-4 W/m2. What is the intensity at a spot that is 72 m away
Consider the induction motor shown in Figure. Redraw the figure showing the current directions in the rotor conductors, the magnetic rotor poles, and the direction of the developed torque if a prime mover drives the rotor at a speed higher than sy..
