ABB Builds HVDC Station To Enhance Michigan Grid, Integrate Wind Power

ABB says it has commissioned a 200 MW HVDC Light station that will enhance grid stability and integrate more wind energy in Michigan.

ABB designed, supplied and installed the back-to-back station for American Transmission Co. According to ABB, a back-to-back system comprises two HVDC converters connected directly to each other, without any direct transmission line, making it possible to fully control the power transfer through the connection.

The company says the voltage and reactive power control features of the system enable the integration of additional wind energy and stabilization of the network. Furthermore, the station's "black-start" capability allows for fast network restoration using power from the other end of the system in the case of a power outage, ABB adds.
