    Abstract:
      Objectives  According to situation that the ship power information exchange system based on the traditional field bus has been unable to meet the needs of modern ship power system for informatization, automation, intelligent and safe operation.
      Methods   This paper proposes the use of industrial Ethernet Modbus/TCP to make up for lack of field-bus. Then, the data center is established by collecting the inherent data of the field bus of the combined ship power system and collecting the real-time data from the online measurement device based on the Modbus/TCP. Correlation theory and neural network intelligent algorithm are used to analyze big data to complete the dynamic power quality monitoring and fault diagnosis of ship power system.
      Results   Finally, the man-machine interface is designed with LabVIEW.
      Conclusions   The feasibility of the software and hardware implementation of the scheme is verified by the laboratory platform.
