Abstract
Unique systems, methods, techniques and apparatuses of a power collection system are disclosed herein. One exemplary embodiment is an MVDC collection system coupled to a utility grid including a collection bus, a plurality of branches coupled to the collection bus, and a branch controller. Each of the plurality of branches include a semiconductor switch coupled to the collection bus, and a DC/DC converter coupled to the semiconductor switch and an LVDC power source. The branch controller configured to determine a fault condition is occurring within the MVDC collection system, determine the location of the fault condition, and isolate the fault condition using at least one of the semiconductor switches and the DC/DC converters.
