Electrical Engineering MCQ
Which of the following is an advantage of Newton-Raphson (NR) method:
- Number of iterations are less
- Applicable to large power networks
- Both of these
- None of these
Correct answer: 3. Both of these
Explanation: The Newton-Raphson (N-R) method is an iterative numerical technique used for solving nonlinear algebraic equations, and it is commonly applied in power system analysis for solving load flow problems. The advantages of the N-R method include:
- Number of iterations are less: The N-R method often converges to a solution in fewer iterations compared to some other load flow methods, such as the Gauss-Seidel method. This can result in faster and more efficient convergence.
- Applicable to large power networks: The N-R method is well-suited for solving load flow problems in large and complex power networks. Its ability to handle nonlinearity makes it a preferred choice for systems with a large number of buses and branches.
