Tenaga Nasional Berhad (TNB) and Electricity Generating Authority (EGAT) HVDC Interconnection between Thailand and Malaysia

Tenaga Nasional Berhad TNB and Electricity Generating Authority EGAT HVDC Interconnection between Thailand and Malaysia

The Malaysia – Thailand HVDC Interconnection was implemented to increase the efficiency and power transmission capacity between the two countries. The 120 km, ±300 kV HVDC transmission line connects converter stations in southern Thailand and northern Malaysia, and includes a full-length neutral conductor.

Teshmont was retained as Owner’s Engineer by both TNB and EGAT, from the original design studies stage of the project through to final commissioning.

Teshmont performed feasibility studies to determine the optimum voltage of the system and to select the optimum conductor size for the transmission line as well as the system and equipment studies needed for preparation of the specifications.

Comprehensive technical specifications for the converter stations and HVDC transmission lines were prepared by Teshmont. Teshmont also inspected manufacturing, administrated construction, and performed commissioning work to ensure compliance with specifications.

The final stage of the project included training and transfer of knowledge and technology to TNB and EGAT to ensure the successful operation of the interconnection into the future.

The project has facilitated bi-directional control of power, in addition to increasing the reliability and dynamic performance of both AC systems.
