ABB has commissioned and handed over the LitPol Link to the Lithuanian transmission system operator Litgrid. The 'Classic' HVDC link connects the power grids of Lithuania and Poland to enable power trading between the two countries, and to strengthen and secure power supply in the region by opening up new cross-border energy sources. This is possible because the LitPol Link forms part of the European Union's Baltic Ring initiative aimed at interconnecting the grids of nine countries around the Baltic Sea, namely Lithuania, Poland, Germany, Denmark, Norway, Sweden, Finland, Estonia and Latvia. The LitPol Link now closes the Ring.
A pooling of these countries' diverse power resources brings numerous advantages. Until now, the Lithuanian electricity system had only been connected with the grids of Latvia, Estonia and the countries to the east.
The LitPol Link is ABB's fifteenth interconnection in the Baltic region alone. It is a 500 MW interconnection based on ABB's HVDC technology in a "back-to-back" configuration, which enables electricity to be transmitted between the unsynchronised Lithuanian and Polish grids. HVDC also provide additional capabilities such as power reversal on-demand - which enables trading and power compensation to reinforce the AC grid and enhance stability. Advanced control and protection features will enhance grid reliability and efficiency, says ABB, bringing benefits to the owner, operator and consumers.
ABB was responsible for the design, engineering, supply, installation and commissioning of the converter station, including high-voltage equipment, power transformers, and thyristor valves. The solution also incorporates the MACH (Modular Advanced Control for HVDC) control system - the most widely deployed control technology in the world for HVDC.
