Electrical Engineering XYZ MCQs
For accurate load flow calculations on large power systems, the best method is:
- G-S method
- Decoupled method
- N-R method
- All of the above
Correct answer: 3. N-R method
Explanation: N-R method (Newton-Raphson method) is widely regarded as the most accurate and efficient method for load flow calculations on large power systems. It is an iterative numerical technique that uses linearization and successive approximations to converge to the solution of the nonlinear power flow equations. It typically converges faster and more reliably compared to other methods, making it the preferred choice for accurate load flow analysis.
