500 kV transmission line design and fault analysis

To be able to keep up with energy demands new transmission lines need to be designed and built. Design and planning is a long process due to the economic, political and environmental reasons. This project will analyze the line design with respect of the efficiency, percent of voltage regulation and power losses. In the second part of the project abnormal conditions will be analyzed for all of the shunt faults occurring on the different locations throughout the line. All data are selected base on the 500 kV line as reference. Conclusion is if we transmit low power over extra high voltage and long transmission line the receiving-end voltage is greater than sending-end voltage, which is undesirable situation, and the faults are more severe if they occur closer to the source.
