With the rapid development of smart grids,information networks and power networks are becoming increasingly interdependent.So studying the cascading Failures of power Cyber Physical System (CPS) helps to ensure the system operates safely and steadily.Considering the communication function of the information network,it is proposed to construct an information network node importance evaluation matrix to reflect the vulnerability of dependent power nodes;For the expression of load redistribution and failure propagation processes,it is proposed to use the vulnerability index as the weight and the fault propagation process as the direction to plot the failure graph which describes the cascading failure;The graph is used to analyse the vulnerability of the power CPS and the results are verified by comparison with existing methods.
