The distribution energy router (DER) is the core of the interacted and interconnected micro grid in future distribution network, which fully meets the needs of the ubiquitous power internet of things (IOT) based future distribution network. The reliability of micro grid which applies the DER is highly related to its cascaded full-bridge converters. With the redundant full-bridge converters and IOT technology, the DER can stand the component failures, hence improve the robustness of the DER as well as the future interacted and interconnected micro grid. For a ubiquitous power IOT technology based DER, this paper proposes a redundancy design for fault tolerant strategy. Several redundancy designs are discussed in detail with operational principles and control strategies. The proposed redundancy design is implemented on the power circuit of one phase for DER consists of a nine-level cascaded full-bridge converter in Saber simulation platform, and the simulation results prove that the redundancy design can minimize the customer’s power interrupt time and the consequent damages to the system.

Reliability is one of the most important properties of integrated supervisory and control system (ISCS) in metro. Redundancy technology, a fault tolerant mechanism, can significantly improve ISCS reliability. This paper introduces a redundancy design schema and its implementation in distributed real-time database, which is the kernel part of ISCS, Including upstream and downstream data redundancy processing technology, fault detection and redundancy switch technology. The result shows that this schema is feasible and reasonable.
