The Study on the Application of Matlab Fault Simulation Technology in Short Circuit Electrical Fire Investigation

This paper takes the low-voltage distribution system as the research object,which uses the Matlab / Simulink software and builds a typical electrical fault simulation model of low voltage power distribution system. This model can imitate the various characteristics about the change of voltage and electric current,through adding different simulation modules and setting different module parameters. The data,which was gathered from these modules,can provide different regular patterns and characteristics of electrical fault for the analysis of the kind of the electrical fire accident.
