Abstract

Safety and reliability of inverter circuit is necessary assurance for the normal operation of STATCOM.In this paper

the open circuit fault of STATACOM inverter circuit is taken as a research object

the data is obtained by MATLAB simulation

the Fourier analysis of three-phase output current is made and a method to collect fault characteristic by the use of DC and fundamental harmonic contents of three phase current is proposed.It is shown by the analysis that use of the method can correctly judge type of fault and locate the faulty.
