On November 11th, the “Conclusion Seminar for the Development and Production of Converter Valves for the ±800kV UHVDC Transmission Project in Jinping-Suinan†was held in Beijing. Liu Zehong, the Director of the Construction Department of the State Grid Corporation of China, and Gao Liing, the deputy director, attended the meeting. The China State Power Corporation Pren Engineering Co., Ltd. as a supplier of equipment made phased results report at the meeting.
Jinsu UHV DC transmission project is the second UHV DC project of the State Grid Corporation of China, and also the model and route guidance project of the UHV DC transmission project. It is the first domestic project to use the converter valve equipment with independent intellectual property rights. Its strategy Significant.
China National Academy of Electric Power Industry Corporation, CLP Preu Power Engineering Co., Ltd. has signed the contract for the supply of converter valves for Jin Su Project in April 2011, and has promoted the overall quality of the company through its leading group, engineering headquarters, and quality control and supervision team. Work, formulate project plans and control of key time points, ensure product quality and project progress, and achieved initial results in equipment design, product technology, logistics procurement, quality inspection, test verification, manufacturing, and workshop environment. On October 29, 2011, a complete set of type tests was successfully completed, which fully validated the excellent performance of the converter valve in terms of structural design, electromagnetic field design, pressure equalization design, etc., and full-scale production of the converter valve module for the project was completed. And quality laid a solid foundation.
At present, the first batch of valve module manufacturing and routine testing tasks have been completed. It is planned to ship and transport valve equipment at the end of March 2012 to ensure that unipolar operation will be completed by the end of June 2012 and bipolar operation by the end of December 2012.
