Solution
Statement - A) AC Load flow studies refer to the transient state analysis of the power system computing voltages and angles at each bus. Statement - B) AC Load flow studies compute voltages and angles at each bus.
Answer: A is false, and B is true.
Explanation: AC Load flow studies do not refer to the transient state analysis of the power system. Instead, they refer to the steady-state analysis of the power system. Therefore, statement A is false. Statement B is correct as AC Load flow studies indeed compute voltages and angles at each bus.
Statement - A) The transmission system has a high X/R ratio. Statement - B) The distribution system has a low X/R ratio.
Answer: Both A and B are true.
Explanation: The X/R ratio refers to the reactance to resistance ratio in a power system. In transmission systems, this ratio is typically high due to the long distances and high voltages involved. On the other hand, distribution systems usually have a low X/R ratio because they operate at lower voltages and over shorter distances. Therefore, both statements A and B are correct.
