The Electrode System I of the Ningdong-Shandong 660 KV DC Electric Power Transmission Demonstrative Project was officially put into commercial operation, revealed from CSR Zhuhou Institute Co., Ltd. on Dec.3.
The project is equipped with five-inch 7,200V thyristors which are developed independently by CSR Zhuzhou Electric Locomotive Co., Ltd. (CSR Zhuzhou) This achievement has smashed up foreign companies' long monopoly of this technology.
As a key project in response to the national strategy of west-east electricity transmission, the operation of Ningdong-Shandong DC power transmission project marked another vital technical breakthrough in the large scale and long distance power transmission in the country.
The HV thyristor is the core part and the "heart" of the HVDC power transmission converter. CSR Zhuzhou has grasped the design, manufacturing and test techniques of HV high-power thyristors with great endeavors. The company has spent several hundred million yuan in building up Asia s first class HV high-power thyristor industrial base. The base is committed to pushing forward the innovation and localization process of the HVDC power transmission technology.
