Research ArticleOpen accessIn the abstractThe Effect of R/X Ratio of the Short Transmission Line on Transient StabilityPrechanon KumkratugProblem statement: The exact short transmission line model consists of the resistance and reactance. Most of previous researches study the transient stability of single machine infinite bus with neglecting the resistance of the line. Thus the simulation results may not close to the practical system. With the consideration with the actual short line model, it causes difficulty of deriving the … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 24 Jan 2012 · 8,057 accessesView PDFCite
