Question

Determine the correctness or otherwise of the following Assertion [A] and the Reason[R].
Assertion(A): Fast decoupled load flow method gives approximate load flow solution because it uses several assumptions
Reason (R): Accuracy depends on the power mismatch vector tolerance.

• A. Both (A) and (R) are true and (R) is the correct reason for (A).
• B. Both (A) and (R) are ture but (R) is not the correct reason for [a].
• C. Both (A) and (R) are false.
• D. (A) is false and (R) is true.

Answer 1

The correct option is D (A) is false and (R) is true.

FDLF method gives approximate solution not because it uses several assumptions but due to the fixed number of iterations.
