Abstract
Conference Title: 2016 Eighteenth International Middle East Power Systems Conference (MEPCON) Conference Start Date: 2016, Dec. 27 Conference End Date: 2016, Dec. 29 Conference Location: Cairo, Egypt Proper operation of any power system depends on robust and continuous performance of the substations. The design of the substation grounding system plays vital role. Since the grounding system should preserve safe and effective protective schemes. This work is to investigate the different grounding systems design of a 500/220 kV substation in Egypt. The design of grounding system to get the optimum values of the desired parameters is performed by developing many M-Scripts of Matlab program. To verify the obtained results, the substation grounding system is designed using developed Ground Grid System. The obtained results are verified by using Module of the Electrical Transient and Analysis Program (ETAP). The best grounding system of the substation is advised to be used to achieve the minimum risk for equipment and workers inside the substation during normal and abnormal conditions.
