Abstract


In this paper, the low - pressure vessel AC power system as the research object , based on the characteristics of the ship power system , combined with land-based power system studies mature theory , the ship power system stability studies . First , according to the characteristics of the ship power system , the study of a three - phase model of the ship power systems , generators, transformers, transmission and distribution lines and load method , on this basis , the combined ship power system characteristics similar to terrestrial distribution system work out applies to the trend of ship power system algorithm - UI - MEPS . Secondly , according to the characteristics of the short-circuit current of the power system of the ship , according to the China Classification Society \According to this approach , the development of the ship power system short-circuit current calculation software , in combination with the China Classification Society the steel ship classification rules 2009 \Then , in order to study the stability of the ship power system , the use of MATLAB / SIMULINK simulation model of the ship power system . The model includes : the simulation model of the synchronous generator excitation system simulation model , the simulation model of the diesel engine speed control system , as well as the load of the simulation model , the use of structures of ship power system simulation model , synchronous generators in stand-alone operation status sudden increase under sudden load reduction , synchronous generators and car operation , plus dual parallel operation of state suddenly , sudden load reduction and different conditions for dynamic simulation to study the stability of the ship power system . The simulation results show that : the established ship power system model to meet the China Classification Society the steel ship classification rules 2009 \Finally, on the basis of the full text of the study , the effective measures to improve the ship power system static stability and transient stability .
