Abstract
A method and system for measuring broadband impedance of a renewable energy power generation device. A voltage disturbance is injected into the renewable energy power generation device by using a disturbance injection device, and three-phase voltage and three-phase current of each of preset measurement points are acquired. Relevant variables before the renewable energy power generation device is decoupled from a measurement device and impedance of a power grid, are calculated according to the three-phase voltage and the three-phase current of each of the preset measurement points. Impedance of the renewable energy power generation device after being decoupled from the measurement device and the impedance of the power grid, is calculated.
