A real-time digital simulation model of the electromagnetic transients of one phase short circuit of double-circuit high-voltage line on the same tower

New models are presented for one-phase earth short circuits of a double-circuit high-voltage three-phase power transmission line (DHTT) and appropriate integration methods as well as the relevant computation scheme are described. Simulation of the electromagnetic transients of the one-phase earth short circuit of the DHTT shows that using parallel processing, the models including their integration methods and computation steps are suited for real-time simulation of faults.
