Measurement method of traverse crossing distance based on moving edge calculation

In order to ensure the security of power system, the measurement method of traverse crossing distance is designed based on the principle of moving edge calculation. Taking ±800kV UHV DC transmission line as the research object, the interference value in the process of traverse cross measurement is collected by particle flow density algorithm, and the performance data of traverse is standardized and recorded according to the collection results. The sag value of traverse cross span distance is obtained by moving edge calculation method, and the traverse cross span distance is realized according to the sag value Accurate measurement. Finally, the experiment shows that the research method has higher accuracy in the practical application process, and can improve the security and stability of power system operation.
