€�Half of the population in the United States lives within 100 miles of the coasts, but most of the wind resources lie between North Dakota and West Texas,” says Michael Heyeck, senior vice president for transmission at the utility giant American Electric Power. Today's conductors transmit AC power well because AC current flows along the outside aluminum "skin" of the cable; the center section carries almost no current. Daniel Ludois and Giri Venkataramanan of the Department of Electrical and Computer Engineering, University of Wisconsin – Madison have issued an article titled „An Examination of AC/HVDC Power Circuits for The application of high voltage dc (HVDC) transmission for integrating large scale and/or off-shore wind generation systems with the electric grid is attractive in comparison to extra high voltage (EHV) ac transmission due to a variety of reasons. My experience with DC power: I am a telecommunications engineer building central offices for some of the largest telcos in the world. In other words, I know what I'm talking about. So, Sub-Stations are important part of power . ABB was the main technology supplier to State Grid Corporation with ABB components and technology, in local partnership. Direct-current high voltage (dc HV). An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. I manage multiple DC plants with well over a thousand AMPs worth of juice. When electricity leaves a power plant today, it is shuttled from place to place over high-voltage lines, those cables on steel pylons that cut across landscapes and run virtually contiguously from coast to coast. Other key products delivered include thyristor valves, DC and AC (direct and alternating current) switchyard equipment and the newly developed DCC800 HVDC control system. 69 kV, 115 kV, 138 kV, 161 kV, 230 kV. ABB has commissioned the Xiangjiaba-Shanghai project, the world's first UHVDC (ultrahigh-voltage direct current) transmission link to go into commercial operation. The transmission lines would be very expensive, so high voltages are used (thousands of volts) to transmit from the generating plants, with relatively thin wires.
