Title: Simulation on Electromagnetic Transient Process in DC Transmission Line of ±800kV Power Transmission Project From Jinping to South Jiangsu
Abstract: The steady state operation voltage and the double 12-pulse structure per pole in ±800kV DC power transmission project from Jinping to South Jiangsu are same as those in ±800kV DC power transmission project from Xiangjiaba to Nanhui,however the transmission capacity,transmission distance and conductor type of the former are different from the latter.Based on the parameters of main circuit of ±800 kV DC power transmission project from Jinping to South Jiangsu,by use of electromagnetic transient analysis software EMTP-RV the electromagnetic transient processes of internal overvoltage and earth short circuit currents along the transmission line under two types of bundled conductor spacing,namely 45cm and 50cm,are simulated respectively,and the maximum overvoltage level of HVDC transmission line under these two spacings is obtained.According a lot of simulation results,the envelope of overvoltage level along the HVDC transmission line and the envelop of earth short circuit currents at different points along the HVDC transmission line are given.Results of this research issue offer technical basis for the design and construction for ±800kV DC power transmission project from Jinping to South Jiangsu.
