In order to work out the accident caused by the impact or frequent current into the ground on person or equipment near the substation when transmission line tower is short-circuited, the technology of multi-point monitoring to scattered current in the ground were studied in this paper. And then the method is verified by simulation and experiment. At the same time, the scattered current of not monitored...
Aiming at the low-frequency oscillation of traction network caused by the high-speed railway electric motor units (EMUs), when transient current control strategy (TCCS) based on traditional PI controller is adopted by the line-side converter (LSC) of the EMUs, by analyzing the PI controller parameter adjustment, it is found that this suppression measure has its limitations. In order to overcome the...
