The Defect Diagnosis Systerm for Grounding Grid
Zhang Da-nin · 2014
To solve the defect diagnosis system for grounding grid,the paper briefly introduces the function and characteristics of the ground simulation software CDEGS,developes a substation defect detection system of grounding grid,and computes the grounding grid model by using the MALZ module. Measuring ground net after the excitation current source injected into the grounding grid in the actual experiment,with ARM9 embedded system processing the data,QT software is used by human-computer interaction,and compared and analyzed with CDEGS software's simulation calculation results that are the distribution of the surface magnetic field. It is easy to diagnose and locate defect in the grounding grid.
