This study investigated the transient energy affection by grid-connected wind farm under lightning. Modeling of the energy system with grid-connected wind farm for Electro Magnetic Transients Program (EMTP) was established efficiently to simulate the transient phenomenon of energy distribution during lightning. The transient phenomena caused by lightning strikes on wind turbines connected to a power system were simulated through three different cases. From the simulation and analysis results, a number of informative suggestions and strategies can be provided to minimize or prevent the possible affection of wind farms and the connected power system during lightning.
► The transient energy impaction of grid-connected wind turbines under lightning are investigated. ► To install an arrester only on the high-voltage side for the step-up transformer for wind turbine is suggested. ► The radial type distribution system has more transient impaction than loop type during lightning on wind turbines. ► Higher voltage supply for end users has less transient impaction than lower voltage under lightning on wind turbines. ► There is no major influence for different short capacity and grid-connected voltage during a lightning strike.
