Therefore, negative Q is lagging the voltage and positive Q is leading the voltage. Using the convention, you should rewrite your implication to be: Lagging PF = Leading Q = Positive Q Also, Leading PF = Lagging Q = Negative Q

Web26.2.1 Reactive power capability curves in the grid code requirements. The safe operational of WT generators equipped with full converter is guaranteed when the terminal voltage is between 90% and 110% of rated value. This range allows the secure transmission of the power into the grid. The lagging power factor (PF) depends on the terminal voltage. Leading and lagging current are phenomena that occur as a result of alternating current. In a circuit with alternating current, the value of voltage and current vary sinusoidally. In this type of circuit, the terms lead, lag, and in phase are used to describe current with reference to voltage. Current is in phase with voltage when there is no phase shift between the sinusoids describing their time varying beha…
