Objectives/background/needs: NTDC system planning to year 2030 required extensive transmission expansion to bring about 30,000 MW power from northern hydro plants. One of the transmission corridors had certain Right of Way and terrain difficulties. In order to transmit 12861 MW through this Dasu corridor, NTDC had reviewed 765 and 500kV options of transmission voltage level for given power transfer levels. NTDC further wanted to evaluate HVDC transmission options as well and then compare with other 765kV and 500kV options. NTDC wanted to evaluate techno-economical study for year 2020, 2022, 2025 and 2030 to see which option is most suited for this required power transfer. Key deliverables and solution provided: Prepared HVDC options schemes, ranking of three options based on transmission lines life time techno-economic studies. Power transfer enhancement studies using FACTS application including series compensation and SVCs. Detailed power system studies, load flow, short circuit, stability and economic studies to rank the alternatives, recommendations, reporting.
