1. If there are any problems with the bus voltages under typical daytime loads, propose a solution for this problem. Define a set of capacitors at various busses in the system to compensate for out-of-tolerance voltage variations.
2. What happens to the bus voltages under nighttime conditions of the capacitors proposed in Problem 1 are left attached to the system at night? Is it ok to permanently connect the capacitors to the power system, or must they be switched?
3. Suppose that the power system is operating under typical daytime loads, and the transmission line between Bus 4 and Bus 5 open circuits. What happens to the voltages on each bus now? Are any of the transmission lines overloaded?
what is the maximum number of carrier frequencies that would ever be needed so that any arbitrarily partitioned region would never have two adjoining cells that use the same frequency
The power factor of the added load is to be adjusted so that the overall power factor of the factory is 0.96 lagging. The factory is fed from a line having an impedance of 0.02 + j0.16 O. The voltage at the factory is maintained at 480 V(rms).
A 50-kW 440-V 50-Hz two-pole induction motor has a slip of 6 percent when operating at full-load conditions. At full-load conditions, the friction and windage losses are 520 W, and the core losses are 500W. Find the shaft speed nm for full-load ..
A battery is limited in the amount of current that it can supply to a load. When disconnected and fully charged, the voltage across the battery terminals is measured to be 13.8 V. When connected to a load that dissipates 18 W of power
(A) What is the current flow of a circuit containing inductances of 1-H and 2-H connected in series to a 440 V 60 Hz source (B) What would the total circuit current flow be if the same two coils were connected in parallel to the voltage source
Write a main program to call a procedure that converts the Fahrenheit temperature value stored in the location labeled TdegF to its Celsius equivalent. The range of temperatures is 32°F to 212°F. The procedure stores the converted temperature
A duplex receptacle with one receptacle outlet always hot and the other outlet switched from two switch locations. The receptacle has two controlled outlets, must be powered through a switch control (SPDT), include all phase, neutral and grounding..
For a Wien-bridge oscillator Given R = 20Kohm and C = 10nF what is the frequency of oscillation Given a required frequency of oscillation of f = 3kHz and R = 5kohm, what should the value of C be
Find two renewable energy application where ac/dc converters are used. Explain qualitatively the role of the converter in the application
A temperature transmitter has an input range of 0 to 100 degrees celsius, an output range of 4 to 20 mA, and anaccuracy of ± 0.5%. The ideal transmitter has a linear output from 4 mA at 0 degrees celsius to 20 mA at 100 degrees celsius.
