Study on overvoltage of DC transmission line in AC to DC transmission project
The AC to DC transmission project uses the original AC transmission tower to carry out DC transmission, and realizes the significant improvement of transmission power without large-scale increase in investment, which has become an important solution to realize energy efficient interconnection. The use of AC tower for DC transmission puts forward different requirements for the combination of overvoltage and insulation. Based on Yangzhou-Zhenjiang ±200kV AC to DC transmission project, the generation mechanism of DC line overvoltage is analyzed, and the level and distribution characteristics of DC line overvoltage are calculated based on PSCAD electromagnetic transient simulation platform. This paper provides a reference for the research on the overvoltage of DC transmission lines in AC to DC transmission project, and the research results have provided a basis for the design and construction of the first AC to DC Yangzhen HVDC transmission project in China.
