Abstract

The invention provides a direct-driven wind turbine group simulation model and a data acquisition method and system thereof. The direct-drive wind turbine group simulation model comprises a direct-drive wind turbine, a multiplying amplifier, a controlled current source, line equivalent impedance and a power grid. The direct-drive fan is separately connected with the controlled current source and the line equivalent impedance and is used for outputting fan current signals to the line equivalent impedance. The multiplying amplifier is connected with the controlled current source and is used formultiplying and amplifying the fan current signals from an external system according to the preset number of fans and outputting the multiplied and amplified fan current signals to the controlled current source. The controlled current source is connected with the line equivalent impedance and is used for outputting a controlled current source signal to the line equivalent impedance by taking the multiplied and amplified fan current signal as a reference value; and the controlled current source signal and the fan current signal are accessed to the power grid through line equivalent impedance. The module is suitable for system simulation analysis of large-scale wind power integration, the simulation calculation amount is greatly reduced, and the engineering application value is improved.

Description

technical field [0001] The invention relates to the technical field of model simulation, in particular to a simulation model of a direct-drive wind turbine group and a data acquisition method and system thereof. Background technique [0002] In recent years, with the rapid development of new energy sources, the global installed capacity of wind power continues to increase. With the continuous improvement of wind power penetration, the transient characteristics of large-scale wind farms will have an important impact on the safe and stable operation of the power grid. Therefore, it is necessary to establish a simulation model that can accurately reflect the fault transient characteristics of the wind turbine fleet, so as to provide a strong guarantee for power grid operation and planning, accident warning and analysis. [0003] At present, the equivalent modeling of wind turbine fleets used in system simulation research often adopts detailed modeling methods, that is, to esta...
