Shengsi Dc Transmission Project Commissioning And Operation Analysis

With the development of the electricity system, a nationwide network of electricity emerging. For the expansion HVDC technology applications to create good conditions and with the progress of power and electronic technology progress and the price of DC power transmission equipment fall, will make HVDC the more obvious advantages, but also more competitive.Shengsi HVDC transmission project is the first commercial HVDC project in China, it's a completely self-developed equipment, design, construction and debugging, as well as China's first double submarine cable,double positive and negative, integrated automation HVDC projects to solve international problems as a weak by the end of the HVDC system stability problems, and ultimately a passive operation.This paper the major works of Shengsi HVDC projects,it also introduces the statements of debugging before operation and the research of inverter side not to retain the minimum exchange unit to achieve passive running after operation.
