EHV-DC System Ties Los Angeles to Northwest
Abstract
Extra-high-voltage direct-current (EHV-DC) power transmission is competitive with extra-high-voltage, alternating-current (EHV) transmission for transporting bulk power over long distances. Advantages and disadvantages of EHV-DC compared with EHV are described. The scope of the civil engineer's participation in this project is shown by describing the route of the line, right-of-way, and structures involved. Pole-type, reinforced concrete tower footings and guy anchors were used wherever soil could be augered. Seventy-six percent of the suspension towers are guyed towers. The valve hall of the terminal building and 4-1/2 acres of the electrical equipment yard are enclosed by metal shielding screen to limit radio interference. A 31-mile electrode line connects the ocean electrode to the converter station. Sixteen repeater stations were constructed for the Microwave Communications System.
