Abstract

The invention discloses a power distribution network CPS safety evaluation method considering communication fault influence and a device thereof, and the method comprises the steps: constructing a physical anticipated fault set, carrying out the physical fault anticipation of a power distribution network CPS one by one, and considering the information faults in the execution process of power distribution automation fault processing services, such as fault positioning, isolation and recovery; constructing an information physical combination anticipated fault set with service correlation; quantitatively analyzing the influence of the communication fault on the execution process of the distribution automation service, and calculating a corresponding safety evaluation index; and finally, sorting and screening the calculated security consequences to obtain an information physical serious fault set in a corresponding analysis scene. According to the method, the influence of the information physical combination fault on the operation safety of the power distribution network is quantitatively analyzed, and the recovery control strategy after the power distribution network fault is effectively combined in the evaluation process, so that the safety evaluation result better conforms to the engineering practical situation.

Description

technical field [0001] The invention relates to a distribution network CPS safety evaluation method and device considering the influence of communication faults, and belongs to the technical field of distribution networks. Background technique [0002] The cyber physical distribution system (CPS) is a multi-dimensional heterogeneous complex system that integrates real-time perception, information processing and dynamic control. The system is integrated. With the massive access of wind power, photovoltaic and other distributed power sources and the wide application of advanced data acquisition, communication and control technologies, the modern distribution network has gradually transitioned to the active distribution system (Active Distribution System, ADS) in order to realize the Real-time perception of power grid operating status and flexible control of power grid dispatchable resources such as line switches, distributed power sources, energy storage, and demand-side resp...
