Abstract :
Pitfalls associated with performing manual DC voltage drop calculations are examined. The possible consequences of these errors are discussed, demonstrating the need for iterative calculation techniques. A method for calculating voltages and currents using computerized load-flow (iterative) techniques is presented. Differences between AC and DC systems are explored, demonstrating the need for time-dependent analysis. The analytical model is expanded to include fault current calculations. Finally, a method for manually verifying load flow models is demonstrated
