WebGeneral curve limits for low-voltage ride through requirements [1] [4]. ... Post fault the reactive current injection has to be continued for a certain period of time depending on the grid code requirements. According to Figure 9, depicted from the German grid code [6] [20] , when the amplitude of grid voltage is between 0.9 p.u and 1.1 p.u ... WebReactive power is required for the voltage stability. According to the Germany grid code, 1% voltage drop requires a slope of 2% positive reactive current injection and the dead band zone is 10% without reactive current injection. b) Variation in voltage and frequency range: plant could operate continuously are established by Germany grid code.
