The following shows a single-line diagram of a 3-phase balanced system

PROBLEM 3: The following shows a single-line diagram of a 3-phase balanced system, where voltages are given in RMS. V. 28


d) Plot P and Q if angle varies in the range [-5°, 5°]. Keep other values as in part (b).

e) Using these plots, what should be the approximate settings for V1 and δ to have the following power amounts: P = 5000 W and = 500 VAr ?

Hint
Engineeringa) Phase Power Component: Three-phase electricity is the most popular way to generate, transmit, and distribute alternating current power. It's a polyphase system, and it's the most frequent way for electric grids to transport electricity throughout the world. Three "hot" wires, each 120 degrees out of phase, make up three-phase electricity. The electricity is delivered from the utility...
