Abstract: Disclosed is a reliable resilient router for a wide-area phasor measurement system of a power grid. The reliable resilient router includes a Data-type data packet processing module, a RetransReq data packet processing module, a RetransReport data packet processing module, a basic data packet processing module, a multi-path forwarding state table module, a content storage queue module and a physical port. The reliable resilient router of the present invention realizes active detection of a lost data packet and a single or batch retransmission mechanism, so that the lost data packet can be directly recovered in the grid from an upstream router through which the lost data packet passes, which improves the recovery time success rate and the high efficiency of the lost data packet, and guarantees the safe and stable operation of the wide-area phasor measurement system of the power grid.

Abstract: Disclosed is a resilient route generation system for reliable communication of a phasor measurement system of a power grid. A named data network is a new network architecture to improve the communication reliability between a phasor measurement unit and a phasor measurement concentrator in power transmission and distribution networks. The lost data packets in a current router can be directly recovered from an upstream router with resilient route, and the optimal RR selection will maximize the success rate of retransmission of lost data packets, thus maximizing the network reliability. The mesh network and ring network structure of the power grid are fully utilized, and a resilient route generation system is provided, wherein the resilient route of each communication pair includes a corresponding primary path and a plurality of redundant sub paths, so that the success rate of retransmission of lost data packets and the network reliability are maximized.
