Case Study: Malaysia-Thailand HVDC Interconnection Project - Teshmont: Leaders in Power Delivery Engineering

Case Study

Malaysia-Thailand HVDC Interconnection Project

Challenge:

Teshmont provided engineering services from initial feasibility studies through to final commissioning assistance for the implementation of an HVDC interconnection between Malaysia and Thailand.

Solution:

The Malaysia–Thailand HVDC Interconnection was implemented to increase the efficiency and power transmission capacity between the two countries. Full bi-directional control of power through the interconnection also provided an increase in the reliability and dynamic performance of both ac systems.  

The project has an initial system rating of 300 MW, with provision for expansion to 600 MW. The 120 km, ±300 kV HVDC overhead transmission line connects converter stations in southern Thailand and northern Malaysia. The transmission line includes a full-length neutral conductor. 

Teshmont provided services including:

  • Feasibility studies to determine the optimum voltage of the system and to select the optimum conductor size for the transmission line
  • System studies needed for preparation of specifications
  • Preparation of comprehensive technical specifications for the converter stations and HVDC transmission lines
  • Technical evaluation of bids
  • Review of converter and transmission line designs, detailed drawings, and studies reports submitted by the Contractor
  • Construction witnessing for the line and substations in association with local consultants
  • Installation witnessing and assistance with commissioning
  • Training and transfer of knowledge and technology
