True false section: answer true or false and provide reasoning.

a. One Sbaseand different Vbase are chosen for different voltage levels for per unit analysis. (T/F)

b. Injected Real Power (Pg - PL) is the magnitude at PV bus. (T/F)

c. when solving active power of all generating units strong coupling between Vmag differs across transmission line. (T/F)

Answer #1

a) True , Because Whenever grid or transmission line contains Transformers There is difference in Voltage levels and we need to assume different voltage base for either sectional sides of transformer primary and secondary while the Base MVA remains same throughout the per unit analysis of given Single Line / Reactance Diagrams .

b) True ,Because the PV bus being Generator Bus supplies the Active Power to the Load

c) False , The Voltage Magnitude Or Vmag is same throughout the transmission Line as At generating unit end all Generator are Coupled together to form Infinite Bus that Have Fixed Voltages supplied to the line
