announces the award of a $60 million order to leading power and automation technology group, ABB by American Electric Power (AEP) to replace a 30-year-old HVDC back-to-back converter station in Texas.
The project scope includes 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 will have black-start capability, which enables fast grid restoration in the event of a power outage, allowing power to be used from the other end of the link.
This is an important feature as the converter station is an integral part of the Oklaunion HVDC transmission link, an asynchronous interconnection between the Texas (ERCOT) and Oklahoma (SPP) power grids.
ABB will bring leading edge technologies as well as significant domain expertise and global application experience to the project.
Brice Koch, head of ABB's Power Systems division explains that the HVDC solution, in addition to enhancing grid reliability and power stability will enable the efficient transmission of electricity across this important interconnection.
ABB will also supply converter valves and the MACH2 advanced control and protection system, which will help meet stringent system performance requirements.
The existing converter station will remain operational during the construction of the new station to minimise the impact. The new station is expected to be operational in 2014.
ABB pioneered HVDC transmission technology almost 60 years ago and has built a vast global installed base, having completed more than 70 HVDC projects around the world with a total transmission capacity of over 60,000 MW.
