摘要

In a fault situation on a microgrid with multiple sources, a ring distribution architecture permits healthy parts of the power distribution network to remain operational while isolating a fault. However, fault localization in a multi-ring power distribution system can be considerably more complex than for a radially distributed network. This paper presents a nonintrusive approach for making microgrid protection systems aware of load operating condition in order to improve fault detection, e.g., for detecting destructive high-impedance and arcing faults.
