Modeling and simulation of 800 kV multi-terminal UHVDC system in India

The World's third Multi-terminal and first UHVDC system in India is planned to be commissioned in the year 2016. This system is designed for ± 800 kV, 6000 MW and transmits power over a total distance of 1728 km. A detailed modeling and analysis of the multi-terminal HVDC system is needed to ensure proper satisfactory operation of the system. The present paper deals with the detailed modeling of the upcoming MTDC system. The complete system is developed, modeled in PSCAD/EMTDC environment and transient simulation studies are carried out. The present study is aimed to gain an insight into the system operation and develop expertise needed to design the system parameters for reliable and stable operation.
