Power Upgradation by Simultaneous AC-DC Power Transmission System

Mohapatra , Sidhartha (2013) Power Upgradation by Simultaneous AC-DC Power Transmission System. BTech thesis.



Due to increasing power demand there are huge requirements for construction of new transmission lines. But ROW (Right of Way) problems are hindering the erection of transmission lines. So instead of erecting new lines the existing AC lines are modified to simultaneous AC-DC lines to increase their power transfer capability close to their thermal limits. This thesis presents the method to convert an existing double circuit EHVAC line into a simultaneous AC-DC transmission line. A triple circuit ac transmission line is compared with a simultaneous AC-DC line. Both the systems are studied and transmission angle of double circuit line is varied up to 800 which is generally not possible for a pure ac line. Sending end power, receiving end power and transmission losses of both the systems are found out and percentage power upgradation is calculated. Simulation is carried out using MATLAB/SIMULINK.
