High Voltage Direct Current System
About
The indigenously developed HVDC prototype is an important step towards reducing Turkey's dependence on foreign energy transmission technologies. This prototype at THS 6 level has proven the feasibility of the technology to be produced with national capabilities and constitutes a basic infrastructure and know-how for future full-scale and commercial HVDC projects.
Product Overview
It is a technology that allows high-power electrical energy to be transmitted over long distances with less loss than alternating current (AC). It also allows the interconnection of two separate electrical networks with different frequencies or phases (asynchronous).

Technology
Modular Multilevel Converter (MMC) architecture is used. This is the latest technology in modern HVDC systems, providing high efficiency and low harmonic distortion.
- Long Distance Power Transmission: Transportation of energy from production centers to consumption centers with minimum loss.
- Subsea Power Transmission: In particular, the transfer of energy generated from offshore wind farms to the mainland or subsea cable connections between countries.
- Interconnection between Networks: Connecting Turkey's grid with neighboring countries' grids with different frequency or phase structure without synchronization problems.
- Renewable Energy Integration: Efficient transmission of power from large-scale solar and wind power plants in remote areas to the national grid.
