AC/DC grid concept evaluation and HVDC integration

PTI analyzes HVDC links and hybrid AC/DC grids using load-flow and dynamic studies to assess system coupling, define control strategies and verify impacts on voltage and frequency stability for secure long-distance transmission.

Protection from transient and subsynchronous risk

PTI conducts studies for insulation coordination, surge arrester sizing and over-voltage protection. Experts evaluate SSR, SSTI and SSCI risks and recommend mitigation measures to safeguard equipment and improve grid reliability.
