A 3000 kVA, 6600 V, 60 Hz, wye-connectedsynchronous generator has a synchronous reactance of 11.3 ohms perphase and negligible armature resistance.Determine the following:a) The excitation voltage (Eaf), line-to-line when the generator is operating at rated voltage and current at apower factor of 0.9 lagging.b) The full load voltage regulationIf the load is changed to a pure resistance and the generator is to operate at rated current and voltage, determine the following:c) The new output power (Pout) and current(Ia)d) Under these new conditions, should the field current(If) be increased or decreased? Explain with phasor diagrams showing the original and new conditions.
What is the blocking probability of the system in (b) when the maximum number of users are available in the user pool?
Decade counter: A decade counter is a counter circuit that counts from 0 to 9 (from 0000 to 1001 in binary numbers) and then resets. Using a 4-bit ripple counter block, 2 inverters and a 4-input AND gate, construct the circuit diagram of a decade ..
Create a bandpass filter with cutoff frequencies of 100-1k, attenuate by at least 3db at desired frequency(100-1k) and at 60Hz attenuate by 10 db. Resistor, Capacitor, Inductor, and Op-amps can be used.
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
A balanced Δ connected load of 15 + j9 Ω/phase is being fed by a Δ connected source. Each of the three lines feeding the load from the source has 0.5 + j0.3 Ω impedance. The voltage at the source is 400 VLL.
Design a multiplier for unsigned binary numbers that will multiply a 4-bit multiplicand by a 3-bit multiplier to give a 7 bitproduct. Assume that the start signal (St) is 1 for exactlyone clock time. When St =1, the multiplier register should belo..
Three identical inductors are connected in series to a 240v 1000hz line, and the circuit current is .6A What is the inductance of each inductor
Write the 9S12DP256 assembly language instructions below a programmer could use to copy the 3rd variable from a 10-byte array into Accumulator B.
Design a circuit that has an input impedance of an inductor value of 3mH if all that is available is resistors,capactiors, and ideal op amps.
A sequential circuit had on flip flop Q, two inputs x and y, and one output S. It consists of a full adder circuit connected to a D flip flop, derive the state table and state diagram of the sequential circuit.
Find the associated answers for: total circuit impeadance (Zt), Current source (RMS), Vc (RMS) w/ power factor, Vr (RMS), all in complex form/ rectangular form. Remember each question has to be done three times, one for each frequency.
A PWM is to be programmed to output a signal with a pulse high width of 150 usec and a pulse low width of 250 usec. What are the values required for prescale (if any) PWMPER and PWMDTY An 8-bit configuration is used and the E-clock is 24 MHz.
