ABB has commissioned a high-voltage direct-current (HVDC) link for American Electric Power that replaces the 30-year-old Oklaunion HVDC back-to-back converter station in Texas. The company says the converter station is an integral part of the Oklaunion HVDC transmission link - an asynchronous interconnection between the Texas and Oklahoma power grids.

The project scope included engineering, supply, installation and commissioning of an HVDC back-to-back transmission system capable of delivering 220 MW of power in either direction. The new system has black-start capability, which enables fast grid restoration in the event of a power outage, ABB notes.

Other key components supplied as part of the solution included converter valves, converter transformers, and ABB’s MACH advanced control and protection system.

“ABB’s domain expertise and global experience enabled us to deliver this link in 22 months, and to minimize outage time for users, the converter station that was replaced remained in operation during the new construction,” comments ABB’s Hanspeter Faessler.
