Effect of Neutral Grounding Protection Methods for Compensated Wind/PV Grid-Connected Hybrid Power Systems

Table 2

A comparison between solid grounding and Peterson coil grounding of 58.6 H inductance on the wind/PV GCS under various fault conditions.

Fault type	Maximum magnitude of fault current at fault location X (Amp)						Current minimization (%)
