摘要
Abstract
De-icing connection of ultra high voltage DC (UHVDC) transmission project consists of Pole 1 and Pole 2 high-voltage converters in parallel connection. Hybrid parallel multi-terminal direct current (MTDC) control was used as de-icing mode control strategy for parallel converters of Xiangjiaba-Shanghai (abbr. XS) and Jinping-Sunan (abbr. JS) ±800 kV UHVDC projects, and current margin control was used as de-icing mode control strategy for parallel converters of Xiluodu Left bank to Jinhua of Zhejiang (abbr. XZ)±800 kV UHVDC project. De-icing mode control and protective principles are analyzed in this paper. De-icing mode test results were analyzed during XS, JS and XZ UHVDC system commissioning tests. During de-icing tests, DC current steady state operation value was slightly larger than setting value, DC current could not be stable. These technical problems were discussed in detail and their causes were analyzed. Solutions of above problems were presented and testified in XS UHVDC transmission project de-icing mode test.关键词
