WebInstantaneous Active Reactive Control (IARC) The most intuitive way to compute the current references during voltage dips is using the vector of voltages v and v⊥and the active and reactive power references P* and Q* The current reference vector can be obtained as: * * p 2 P i v= v (7) * * q 2 Q i v=^ v (8) i i i= +p q (9) WebThe THD curves are plotted to suggest and help in selecting the amplitude and frequency of q-axis injection current for designing the q-axis injection current based islanding detection technique (IDT). The studies are carried out on a partial converter based small wind energy system on per unit basis to have generalized conclusions.
