Simulation and Power Flow Analysis of the Duyen Hai – Phu Lam Transmission Line Using Power world Simulator

The artical presents the simulation and analysis of power flow on the 500kV Duyen Hai – Phu Lam transmission line using PowerWorld Simulator software. This is one of the most important transmission lines in the Southern Vietnam power grid. The objective of the study is to evaluate the transmission capacity, voltage stability, and power loss in the system. Thereby, recommendations for operation and suggestions for improvement are made. The simulation results show that the system operates stably under baseline conditions, but there is a risk of a slight voltage drop at the Phu Lam load node when the load increases.
