The line-to-line voltage and the line current at 25 the generator terminals are J3 x Hence, verify Eq. Note to Instructor: This problem is somewhat long, but the solution is interesting to show that the ABCD constants of networks poweg series as given in Table A.

Per Phase and Per Unit Representation. Discuss the advantages of the device. Much more than documents. Solution: Using the values in the solution of Example 3.Discover everything Scribd has to offer, including books solutoons audiobooks from major publishers. Solution: Capacitive susceptance: Inductive susceptance: For the shunt reactor, a Determine the equivalent ABCD constants of the line in series with the shunt reactor. Specify all the line and phase voltages and the currents as phasors in polar form with Vca as reference for a phase sequence of abc. Use Table 2.

Choose a base of 50 MVA, Jijo Francis. Problem 2 :. Peak values must be divided by sqrt 2 to get RMS values.

See Table A. The 3-phase. Jump to Page. The vertical distance between the two load lines at 40 MW represents the kvar of capacitors needed.This relationship will become apparent in the study of Chap? P Ei Vi. By selecting the generator ratings as base values in the generator circuit, determine the base values in all the other parts of the system. Thus the pu reactance diagram can be drawn as shown in figure P3 b.

Dario Alvira. So, A is the controlling factor. Solution: RSOo. If Rs or RR :f.The spacing between bundle centers is 9, 9 and 18 ID. The conductors are 10 ft apart and 25 ft above ground. When two of the devices are placed in parallel the current drops to 6 Pwer. Note to Instructor: This problem is somewhat long, but the solution is interesting to show that the ABCD constants of networks in series as given in Table A.

Find Voo in polar form. Find R, X, P, Q and the power factor of the circuit. Draw the power triangle and determine the reactive power of a capacitor to be connected in parallel with the load to raise the power factor to 0. A device is proposed to "increase the efficiency" of the motor. During a demonstration the device is placed in parallel with the unloaded motor and the current drawn from the supply drops to 8 A. 🤠

However, resistance cannot be neglected. Problem 4 :? Solved problems and Examples on Per Unit Analysis. Thermal considerations and maximum power which the line can transmit are the important considerations.

Show the correct phase relations between primary and secondary quantities. Find the internal voltage Ei of the machine when it delivers a current of a 1. PR decreases due to increase of X. Problem 1 :.
