The insulation level of power apparatus is mainly determined by the amplitudes and waveforms of system overvoltages. The substation is handled as a lumped equivalent model, and the detailed substation structure is not taken into account in present switching transient calculations. In this study, the influence of considering a substation structure on the switching transient calculation of a 1000-kV ultra-high-voltage system is analyzed, and the factors affecting this calculation are obtained… CONTINUE READING
