Title:
SYSTEMS AND METHODS FOR NETWORK FAILOVER IN DIGITAL SUBSTATIONS
Document Type and Number:
Japanese Patent JP2018183040
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide systems and methods for network failover in digital substations.SOLUTION: A method includes receiving, by an intelligent electronic device (IED) from a process interface unit (PIU), in parallel a pre-configured data stream via a point-to-point connection and other data streams via an Ethernet network. The method includes determining that the following failure conditions is satisfied: a frame in the pre-configured data stream is lost or delayed, quality of the data in the frame in the data stream is below a first threshold, period of the time associated with the data in the frame in the data stream is below a second threshold, or a health indicator associated with the PIU is below a third threshold. The method includes identifying a redundant frame in the other data streams, and using the redundant frame for further processing if the quality of data in the redundant frame is satisfactory.SELECTED DRAWING: Figure 1
