Can ultra-high voltage power transmission bring ... shows that most UHVDC lines can reduce the emissions of air pollutants. The two lines with the highest environmental benefits are South Hami–Zhengzhou and Xiangjiaba–Shanghai. Every TWh of electricity they transmit can reduce NO X by 842 and 813 tons, SO 2 by 544 and 555 tons, and primary PM 2.5 by 121 and 178 tons, respectively.Author: Yuan Li, Bo-Wen Yi, Ya Wang

HVDC converter stations - Hitachi ABB Power Grids is converted from alternating current (AC) to direct current (DC) and vice versa in a converter station. This is done by means of high-power, high-voltage electronic semiconductor valves. A semiconductor valve is a device that can carry current in one direction only, and which prevents current from flowing in the opposite direction.
