ABB has been designing and building HVDC systems for 50 years. In that time we have pioneered breakthrough technologies and supplied more than half the world’s HVDC projects – a unique achievement that gives ABB an unrivaled base of experience.
Pre-contract project team
A project team with a broad and experienced background in HVDC is formed and presented to the customer. The team, supported by a skilled line organization, is responsible for all project work, both before and after the contract is awarded.
Conceptual and detailed design
Much of the design work is performed as part of the pre-contract proposal. Main circuit parameters are defined and conceptual drawings for buildings and layout are discussed with the customer. When the contract has been awarded, the detailed design of all systems, civil works and switchyards is performed using advanced CAD systems.
Manufacturing
 |
| In Ludvika, Sweden, work almost 500 employees. |
ABB has the biggest HVDC production, assembly and testing facilities in the world. The assembly plant in Ludvika, Sweden, has a production capacity big enough to meet world demand.
Testing
Prior to delivery, the control and protection system is connected to a HVDC simulator. System functions, control hardware and software are verified, disturbance tests are performed, and each component is exposed to a thorough burn-in period during both normal operation and abnormal fault conditions.
Civil works and installation
ABB uses local contractors, carefully selected for their competence and experience and managed by ABB personnel on site.
Commissioning
After installation, which is carried out by highly qualified local contractors under ABB supervision, ABB commissioning engineers perform low voltage and high voltage tests. Filter performance, losses and capacity are also measured.
