Research And Application Of Fault Diagnosis System For Ship Power

The main content of this thesis is to analyze the fault features and principles of marine electric power system protection; compare the difference between land and marine power grid; achieve fault diagnosis method through researching the state of circuit breakers and protection relays also the disoperational or misoperational situation. Use a practical marine power grid as the research object to build a mathematical model of system failure. Compile the core diagnosis program to select the most advantageous fault states from fault domain based on the model and genetic algorithm toolbox on the MATLAB computing platform. Build the diagnosis software by.NET Framework and C# language, the dynamic link libraries of MATLAB is used as the data interface of this system.
