Abstract

Aiming at the situation that the method to evaluate grounding grid’s safety in substation is simplex currently

the application to use grounding analysis software in grounding grid’s safety evaluation is summarized. Numerical analysis can compensate for the deficiency of field test and plays a irreplaceable role in grounding grid’s evaluation

design and running attention

where field test is not so good. Using a method combining field test and theoretical arithmetic

the solution of grounding grid’s safety evaluation is proposed

which complies with the needs of state inspection and condition-based maintenance for equipment. The basic processes and evaluation application cases of grounding network under the analysis software is also presented.
