Abstract

Bus differential protection is effective measures to cope with the bus-bar fault in ship MVDC system. A realization of DC bus-bar protection is based on digital protection device which are suitable for complex medium voltage power system. Firstly, the principle of DC bus-bar differential protection, the action characteristic and the connection mode of current transmitter are introduced. After that the dead zone of DC bus-bar protection and its counter measures are analyzed. Finally, the measures to increase the reliability of DC bus-bar protection are discussed according to the special environment of shipboard power system. The analysis results can be used as a reference for Ship MVDC power system protection design.
