Recurrence of Accident Based on the Hornsea wind energy program model, the accident processes shown in Figures three and four are reproduced, along with the simulation benefits are shown in Figures 7 and eight, respectively. For comparison, thinking about that the voltage sag on the Hornsea wind farm that caused the blackout accident started at 16:52:33:490, a single-phase voltage sag fault was set at time node A (3.490 s) inside the simulation. It may be located by comparing Figures four and 8: 1. In the course of the simulation time of 3.490.590 s, inside the AB interval, the maximum drop on the 35 kV bus voltage on the Hornsea wind farm is approximately four . This corresponds to a five drop inside the voltage of the 35 kV bus inside 16:52:33:4906:52:33:600. Through the simulation time of three.590.695 s, within the BC interval, the vo.
