6 Key Problem The effect of wind power cannot be neglected anymore Grid operators expect wind turbines to behave like conventional synchronous generator: no switch-off during voltage dips high short circuit current voltage buffering through reactive current during voltage dips fast recovery of active power New grid codes for wind turbines 1.25 APCG / 5MOP8_EN-(Netzkurzschlussverhalten-Energieerzeuger).PPT / Dr.MÖHLENKAMP 6
7 Key Problem definition for the wind turbines resulting from the grid connection requirements 1. Extended frequency range: 47.5 Hz - [49 Hz - 51 Hz -] 51.5 Hz 2. Extended voltage range: 8 % - [9 % -] 11 % (for permanent operation) 3. Power factor can be chosen from 1 % active to 1 % reactive current to match the demanded reactive power at the grid connection point [cos ϕ =,95 at low voltage side] 4.
