ABB, a global power and automation technology company, won orders worth $45 million to strengthen Sweeden’s power grid from Svenska kraftnät, the Swedish National Grid operator. ABB will supply three 400 kV substations.
The Sege 400 kV substation in southern Sweden will be replaced to improve grid reliability and supply quality power to the city of Malmö and to the Skåne region. In northern Sweden, two new 400 kV substations, Djuptjärn and Högnäs, will secure power supply to the city of Kalix. Högnäs, will also enable the integration of clean wind energy to the national grid in the Västerbotten region. The substations are scheduled to be commissioned in 2015.
ABB’s project scope includes the design and supply of engineered packages for the high-voltage air-insulated switchgear (AIS) substations. Key products and systems to be supplied cover a range of high-voltage equipment including an innovative combined disconnector circuit breaker (DCB).This DCB integrates the disconnecting function into the circuit breaker and eliminates the need for two separate free-standing disconnectors, making it possible to reduce the footprint of the substation by up to 50 percent. The substations will also be equipped with IEC 61850 based open control and protection systems and equipment.
