Abstract
This paper comprehensively introduces and summarizes the converter valve block strategy of the DC protection based on Xiangjiaba-Shanghai ±800 kV UHVDC project. In order to obtain more smooth and fast or more secure stop effect when relevant fault has been detected, the converter need to be removed and isolated as soon as possible to prevent the further breakdown and reduce the impact on the device and power grid. in this project, the different fault conditions are tested and simulated on site, the primary device is effectively protected through phase-shift, temporary stop, block, etc. According to the different combinations and delay of these fault clearing actions, the DC protection block are divided into four categories.关键词
