Reconfigurable inverter: An approach to self-healing of distributed generation

To meet the increasing demand of electric energy, the distributed generation has been put in more and more applications. Being the key part of the distributed generation, the inverter may break down, which makes the normal generation unavailable. To solve this problem, this paper proposes a reconfigurable inverter which based on paralleled similar modules. And the reconfiguration method is designed based on the UPnP Protocol. Compared with traditional high power inverter, the proposed inverter can diagnose circuit fault and recover normal operation from this fault status. This approach can reduce the equipment maintenance frequency and guarantee reliability of distributed generation.
