This paper presents the design of the thyristor valve for the 3 Gorges-Shanghai II 3000MW, ±500kV HVDC scheme. The thyristor valves are based on AREVA's H400 series valve design using 7.2kV 5" electrically-triggered thyristor technology and the scheme is the first application of the valve design for such a voltage level. Details of the valve configuration, the cooling circuit, as well as the...
Aiming at the present situation of the steelmaking end-point control at home and abroad, a neural network model was established to judge the end-point. Based on the colour space conversion and the fiber spectrum division multiplexing technology, a converter radiation multi-frequency information acquisition system was designed to analyze the spectrum light and image characteristic information, and...
