Improving the Performance of Saturated Cores Fault Current Limiters by Varying Winding Density in the AC Coils

Abstract: Effect of the winding density in the AC coils on the performance of a saturated cores fault current limiter (SCFCL) has been studied, exploiting Finite Element Analysis. For a given design, a fixed number of turns was concentrated at the center of the AC coils limb, resulting in high windings density. The coil length was then increased gradually along the limb, decreasing the winding density and therefore decreasing the coil impedance. However, we found that the ratio between the fault to nominal state impedan… Show more

“…The concept in its basic form [19] has seen many modifications and studies while following the developments. The improved characteristics of novel SCFCL can easily be tuned to the general and specific grid requirements by adjusting the physical parameters of the magnetic core structure, AC and DC winding parameters and by controlling the DC bias current [20], [21]. The work addressed here belongs to the nonsuperconducting, novel SCFCL.…”

“…The authors in [60] intensively investigated the correlation between the design parameters of coils and iron cores and their influence on FCL characteristics. The effect of the winding density in the AC coils on the performance of a SCFCL was studied in [30]. A methodology to simulate the dynamic behaviour of the saturated core SFCL in an electrical grid was presented in [61].…”

“…The first is the split in the AC coil. Following the concept described in [21], the coil is split so that the limbs' center region-where saturating field is in the core, due to its farthest distance from the permanent magnets-is minimal. Leaving this point under a lower exposure to direct AC flux helps it remain in a deeper saturated region during nominal grid operation.…”
