| Abstract: | Based on the experience of DC filter design for ±500 kV HVDC transmission projects, this paper analyzes the key issues of DC filter design for ±800 kV UHVDC transmission project, including resonance of DC side and typical faults of DC filter, and introduces the models and methods for the typical faults calculation of DC filter. Taking Yunnan-Guangdong ±800 kV UHVDC transmission project as an example, the paper verifies the resonance of DC side and calculates the transient ratings of DC filter components, showing that the design of DC filter of the project is reasonable, and it can meet the requirement of the project operating safely. |
