Project Title: POWER UPGRADATION IN COMPOSITE AC-DC TRANSMISSION SYSTEM
Brief Introduction:
Voltage that is longer additional is high ac lines can't be loaded with their thermal limitations to keep enough margin against transient uncertainty. Due to the scheme proposed in this task, you can load these relative lines very close to their limitations being thermal. The conductors are allowed to carry ac that is usual with dc superimposed onto it. The added dc power flow doesn't cause any transient instability. This project provides feasibility of converting a circuit that is line that is double composite ac–dc power transmission line getting the benefits of synchronous ac–dc transmission to improve safety and damping out oscillations. Simulation and experimental studies are executed for the control that is coordinated well as independent control of ac and power that is dc. No alterations of conductors, insulator strings, and towers associated with the general line that is original needed. Substantial gain in the load ability from the line that is general acquired. Master controller that is ac that is current and regulates the dc current orders for converters online such that conductor present never exceeds its thermal limitation.
