摘要： The application provides a method and apparatus for analyzing reliability of a cyber-physical system (CPS) of a very-large-scale (VLS) battery energy storage power station, which solves a problem that due to large and complex topology of communication and monitoring systems of a VLS battery energy storage power station, operation efficiency thereof is greatly reduced and the danger of power station shutdown may be caused when a communication and monitoring device fails. The method includes the following operations. Information disturbance data is obtained based on a preset reliability model of an information system. A failure rate and a repair rate of a cyber-physical interface apparatus are obtained based on a preset reliability model of the cyber-physical interface apparatus. A reliability model of the CPS of the VLS battery energy storage power station is obtained based on a preset reliability model of a physical system, the information disturbance data and the failure rate and the repair rate of the cyber-physical interface apparatus. A reliability index of the VLS battery energy storage power station is obtained based on the reliability model of the CPS of the VLS battery energy storage power station.
