Beschreibung
Zusammenfassung:	The invention relates to a fault early warning system for an electric power communication network and a power grid and a working method, and the method comprises the steps: determining a service coupling relation between the communication network and the power grid according to the operation state data of the power grid and the safety protection data of the communication network based on a communication event and a power grid event corresponding to a fault alarm event; combining a power grid event corresponding to a fault alarm event in the power grid and a communication event corresponding to the same fault alarm event in the communication network into an associated event chain, preprocessing the event chain, and carrying out fault diagnosis and fault point positioning according to the characteristics corresponding to the alarm sequence and the relationship between the characteristics; pushing risk items in the alarm event to designated workers in a power grid and a communication network; and determining key
