The IPP DC Line (or Path 27) is a bipolar HVDC transmission line between Adelanto Converter Station in Adelanto, California and Intermountain Converter Station near Delta, Utah. It is a bipolar overhead power line long, and can transfer a maximum power of 2,400 megawatts at ±500 kV. The part of the line that travels through the Mojave Desert is followed by many other AC 500 kV lines and Interstate 15. The Pacific DC Intertie is the other HVDC line serving Los Angeles. This HVDC line is owned and operated by the Los Angeles Department of Water and Power (LADWP). HVDC lines such as the Intermountain line and the Pacific DC Intertie can be distinguished by having two transmission wires, rather than the three necessary for transmission of three phase AC power. == History == ABB Group, a Swiss-Swedish multinational corporation headquartered in Zürich, Switzerland, was the primary entity commissioned for this turnkey project in the mid-1980s. ABB also had responsibility for the converter stations, which were commissioned in April 1986. In 2008, ABB received the order for an additional upgrade. This upgrade included delivery of the MACH2 control and protection system along with additional AC filters and cooling systems. This upgrade has allowed the link to reach a transmission capacity of 2400 MW (2.4 GW). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Path 27」の詳細全文を読む スポンサード リンク
