Cascading failure risk perception for a wind power base Early Warning

The present invention relates to cascading failure risk perception for a wind power base and Early Warning System. The present invention is obtained by SCADA and WAMS real-time operation mode data grid and wind farm, combined with wind farms historical data to get wind power grid may occur current disturbances establish reasonable contingency set of wind turbine dynamic models and fan security model to simulate after grid failure dynamic operation of wind farms, stability analysis to transient after the fault wind power base occur, and static security analysis after a fault removal, through a series of indicators suitable for cascading failure warning large-scale wind power base built on the current grid the occurrence of wind power to be safe and stable situation after the disturbance calculated assessment, risk analysis of large wind power base of the cascading failure, for online safety warning after wind power system disturbances. The present invention is easy to implement, can directly reflect include large-scale wind power base of power system safe and stable operation.
