For the single-line diagram in the image, convert the zero-, positive-, and negative-sequence reactance date to per-unit using the given base quantities. Use subtransient machine reactances.Then, USE PowerWorld Simulator, create the generator, transmission line, and transformer input data files.Next, run the Simulator to compute subtransient fault currents for (1) single line-to-ground, (2) line-to-line, and (3) double line-to-ground bolted faults at each bus. Assume 1.0 per unit prefault voltage and neglect prefault load currents and all losses. Note: L2 = 25 kmShow input data files (machine, transmission line and transformers), output data (fault currents, bus volatges and line currents), and screenshots of the Simulation.
Answer True or False, then correct errors or explain if any: 1. The term pole in filter terminology refers to the feedback circuit. 2, A voltage shunt feedback with Ai-10, A-20, p 0.45, then Aif will be 1. 3. The integrator Op-Amp circuit can be used to produce square waves. 4. The equivalent circuit of the crystal oscillator is series and parallel (R, C) components. 5. The transistor in a class A power amplifier conducts for the entire input cycle. 6. Bypass capacitors in an amplifier determine the low and high-frequency responses. 7. The midrange voltage gain of an amplifier is 100. The input RC circuit has a lower critical frequency of 1 kHz. The actual voltage gain at f- 100 Hz is 100. 8. The Bessel filter types produce almost ripple frequency response. 9. RC phase shift oscillators are based on both positive and negative feedback circuits. 10. In a high-pass filter, the roll-off region occurs above the critical frequency,
Q.1. Answer True or False and correct errors if found 1. In a certain Op-Amp. if Ad=3500, Ac=0.35, the CMRR=100dB. 2. The voltage series feedback can increase both input and output impedances. 3. A two-pole Sallen-Key high-pass filter contains one capacitor and two resistors. 4. The main feature of a crystal oscillator is the high frequency operation. Each transistor in a class B power amplifier conducts for the entire input cycle. ✓ The Q-point must be centered on the load line for maximum class A output signal swing 7. The differentiator Op-Amp can convert the triangle waveform into sinewave. ✗Class AB power amplifier eliminates crossover distortion found in pure class A. 9. Wien-bridge oscillators are based on positive feedback circuits. 10. The band-reject filter is composed of multiplication of LPF and HPF.
