This paper proposes a new concept to control a bidirectional LCL converter which is suitable for applications in mobile mining equipment. This converter employs two DC/AC insulated-gate bipolar transistor-based (IGBT) converters and a passive LCL which replaces the more common high frequency transformer and plays the most important role in energy conversion. Compared to the previously known control...
Recently, DC microgrids have become a viable option for mining distribution systems. Fault diagnostics and protection are known challenges in DC microgrids. In this paper, we present an overview of the existing strategies for fault diagnostics and protection of a DC microgrid and apply them to an open cut DC mine scenario, which includes large electric excavators. We propose a comprehensive fault...
