HVDC Transmission with STATCOM
Most of the HVDC power converters with thyristor valves are assembled in a converter Bridge of Six pulse configuration. Converter transformers with one DC side winding as an ungrounded star connection and the other a delta configuration. Comparative studies of the two systems of HVDC CIGRE model without STATCOM and with STATCOM were performed. In these

During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

Simulation of GIC in the North Island of Aotearoa New Zealand Based on Magnetotelluric Measurements
Abstract New magnetotelluric (MT) data, combined with older MT data are used to simulate geomagnetically induced currents (GIC) in the power network of the North Island of Aotearoa New Zealand for two geomagnetic storms. For the May 2024 G5 Gannon Storm, simulations use magnetic field data from two separate locations—the Intermagnet geomagnetic ...

HVDC Circuit Breaker Development and Applications in VSC-HVDC Transmission Project
Abstract High voltage direct current (HVDC), especially voltage source based HVDC (VSC-HVDC), transmission technology has been expanding in recent decades. HVDC circuit breaker therefore attracts significant interest due to its abilities of current interruption and fault isolation.

Transformers in HVDC Transmission
Power transformers are integral in the HVDC transmission systems and provide multiple functions. Correctly optimised transformers lower the cost for other equipment in HVDC schemes. This article describes the basics of HVDC and gives a view of where the HVDC development stands today.
