Study On Fault Response And Survivability Assessment Simulation Of Ship Power System

As the constant change of current international situation and the increasingly complex international relations,the military war status between countries is intensified.More and more countries put the ship as an important tool to master their sea control right.Thus,the design and manufacture of ship becomes their research focus.In addition,the development of weapons and equipment is an important factor of measuring a country's military strength,and weapons play a more and more important role in modern military war.In recent years,more kinds of weapons have been developed and lots of new technology has been used to them.The ships' attack ability has obviously improved,therefore,studying on how to cope with the fault effectively and improve the survivability is imminent.A new method of ship power system fault response is presented by using the new concept vector,which is proposed based on graph.This method proposed a table called energy algorithm,as a response strategy when fault occurred.Based on the existing integrated ship power system simulation platform of our laboratory,the fault response and survivability assessment simulation software of ship power system has been developed.Simulation software is a MFC project with SQL Server 2000 as the data supporting,written in C++ language.All of the analysis,design and program were followed by the object-oriented thoughts and methods.The simulation software's main function contains: Set up the structure of ship power system in the visual interface,generate the corresponding energy algorithm tables,set a fault freely,and give the next coping strategies;After building the system structure diagram,set the parameter properties of components,calculate the damage probability of each device after it was hit by a weapon,calculate the survivability of the whole ship power system,and assess the current damage level of the system.Finally,through the analysis and calculation of practical example,the correctness,reliability and practicability of the simulation system has been proved.The research works and has certain practical guiding value.
