The invention discloses a high-reliability damping reshaping method for a large-scale new energy power station, which mainly comprises an inverter-side current outer loop control method and an inverter-side current feedback active damping control method of a converter of the new energy power station, for solving the problem of power oscillation and harmonic resonance caused by impedance coupling of the multi-LCL type field station converter. The invented inverted-side current feedback active damping control method, with no need of an additional current and a voltage sensor, not only effectively reduces the influence of the resonance frequency deviation caused by the converter control on the resonance suppression, but also improves the influence on the stability control of the field stationconverter by the impedance variation of the grid under the digital control, which makes the equivalent virtual damping resistance exhibit a large positive resistance characteristic, and improves thestability and reliability of the large-scale new energy power station.
