Devices absorb reactive energy if they have lagging power factor (are inductor-like) and produce reactive energy if they have a leading power factor (are capacitor-like). Electric grid equipment units typically either supply or consume the reactive power: • Synchronous generator will provide reactive power if overexcited and absorb it if underexcited, subject to the limits of the generator capability curve. WebFirst, the transmission system itself is a nonlinear consumer of reactive power, depending on system loading. At very light loading the system generates reactive power that must be absorbed, while at heavy loading …
