In view of the large number of systems at the power network dispatching master station end and the difficulty of data sharing， a new mode of the fault information management system design is proposed. That is， on the basis of the existing data center， a system conformable with the status quo of the local power network should be established， which is capable of realizing not only highly efficient utilization and sufficient sharing of the relevant data and information on relay protection， but also the automatic and networked fault information analysis， computation and management along with the standardization of the working mode by using the setting computation and setting sheet distribution functions. Thus the automatic closed loop management of the three systems of setting computation， fault information analysis and setting sheet distribution is effectively realized and practiced in Anhui Power Grid.
