The Defect Diagnosis System for Grounding Grid of Substation
Zhang Da-nin · Northeast Electric Power Technology · 2014
The paper briefly introduces the function and characteristics of the ground simulation software CDEGS and developes a substation defect detection system grouding 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,it compared and analyzed with CDEGS software's simulation calculation results of the distribution in the surface magnetic field,it is easy to diagnose and locate defect in the grounding grid.
