AEP Taps Siemens to Modernize HVDC System Welsh in Texas

American Electric Power (AEP) chose Siemens to modernize its HVDC back-to-back link at its 600-MW Welsh HVDC station in Titus County, Texas. Siemens will upgrade its 20-year-old system by installing new control and protection technologies, replacing the cooling, heating and ventilation, and incorporating new harmonic filters and shunt reactors. This will be the first Siemens mid-life control and protection HVDC modernization in the United States.
