Texts: Note: Please label the answers clearly. (Power System) THE SOURCE [The overwhelming majority of power sources are three-phase synchronous generators. Motors, usually Induction Motors, are some of the most common and often the largest loads. Synchronous Motors are also used. (The big change in progress is renewable sources and storage, feeding the system via power electronic dc-ac converters. A second change is the use of dc systems for distribution and utilization, fed by renewables and storage. Microgrids - which have been around forever as co-generation - aggregate some of these into hybrid, ac or dc systems)] 4. A 1 MVA, 3-phase, 4 pole, 60 Hz, 4160V, round-rotor Synchronous generator supplies the induction motor in problem 1. Generator Motor The simplest model for the generator is an ideal ac voltage source Eg (variously called the excitation, Generator Generator Zs Synchronous Impedance induced voltage, generated voltage, or voltage behind jXs Ra synchronous reactance) in series with its synchronous impedance, as shown. Notice, laziness is here already -- it is understood that this is the line to neutral model and the generated voltage Eg is line to neutral. I added a suffix 'g' to indicate Eg comes from the generator). Similarly, Vt is the line-neutral terminal Vt dc Field Generated Voltage in Three Phase Armature or Stator Terminals Motor Terminal Voltage voltage of the generator and the voltage applied to the motor. The generator synchronous impedance is given to be Ra + iXs = 1 + i16 ohm at 60 Hz. The motor draws full load, 0.8 power factor lagging, at 4160 V. Determine the internal voltage Eg of the generator (Magnitude Line-Neutral and angle). What is the corresponding value of IEgl expressed as a line-line voltage? Calculate the complex power supplied by source Eg.

9. Tax Cuts or Entitlements An economist believes that the distribution of the opinions of U.S. adults on whether tax cuts or entitlements are more important is different from the one shown in the graph. The economist randomly selects 600 adults and asks each which is more important-keeping Medicare, Social Security and Medicaid or cutting taxes. The results are shown in the table. At $\alpha = 0.01$, are the distributions different?

5. [4+8+3 marks] Consider the function $f(x) = \begin{cases} 0 & \text{if } -\frac{1}{2} \le x < 0\\ 1 & \text{if } 0 \le x < \frac{1}{2} \\ \pi \sin \pi x & \text{if } \frac{1}{2} < x \le \frac{1}{2} \end{cases}$ (a) Use the convergence theorem to find the sum of the Fourier series of $f$ on $[-\frac{1}{2}, \frac{1}{2}]$. (Do not find the Fourier series). (b) Find the Fourier cosine series of the function $g(x) = \pi \sin \pi x$ on $0 \le x \le \frac{1}{2}$. (c) Use your answer in (b) to show that $\sum_{n=1}^{\infty} \frac{1}{(2n - 1)(2n + 1)} = \frac{1}{2}$.
