Number of switches required to control luminaire from two control points.

Question

Question Two A generating station consisting of two generators, one of 20 MVA, 11 kV, 0.18 pu reactance with the unit transformer of 20 MVA, 11/132 kV, 0.08 pu reactance, another of 30 MVA, 11 kV, 0.18 pu reactance with the transformer of 30 MVA, 11/132 kV, 0.12 pu reactance, transmits power over double circuit 132-kV transmission line. Each line is having reactance of 120 ohms per phase. Determine the fault current supplied by the generators to a three-phase solid fault on the 132-kV bus-bar at the receiving end. Neglect pre-fault current and losses. Assume pre-fault generated voltages at rated value.

4v+9v+8v=-3v+6v',-5v, where vi and vo are the input and output voltage, respectively.

I decided to focus on the magnitude where I do the normalization on low and high pass and have the bandpass as dB(dB(decibel), with frequency cutoff, I manage to get accurate but have trouble controlling the frequency cutoff accurately and the bandbass isn't working properly. As such I need help.My Code: % Define frequency range for the plot f = logspace(1, 5, 500); % Frequency range from 10 Hz to 100 kHz w = 2 * pi * f; % Angular frequency % Parameters for the filters R = 1e3; % Resistance in ohms (1 kΩ) C = 1e-6; % Capacitance in farads (1 μF) L = 10e-3; % Inductance in henries (10 mH) % Transfer functions H_low = 1 ./ (1 + 1i * w * R * C); % Low-pass filter H_high = (1i * w * R * C) ./ (1 + 1i * w * R * C); % High-pass filter H_band = (1i * w * R * C) ./ (1 + 1i * w * L / R + 1i * w * R * C); % Band-pass filter % Cutoff frequency for RC filters (Low-pass and High-pass) f_cutoff_RC = 1 / (2 * pi * R * C); % Band-pass filter cutoff frequencies f_lower_cutoff = 1 / (2 * pi *…
