Current Limiter

The increase in demand for electric power and the insertion of a distributed generation led to the rise of the short-circuit current in substations. Most of these Brazilian substations were designed decades ago, because of that their equipment may not support the new short-circuit current levels. To protect the installed equipment and avoid excessive costs replacing old devices, it is possible to install Fault Current Limiters (FCLs). This document is a report from an R&D project that evaluated FCL topologies considering real parameters in simulation from used equipment, concluding that the selected FCL topologies accomplished their technical objective. However, before implementing these topologies in the distribution system, one should consider the technical and economic feasibility of using semiconductor switching devices.

Nowadays, the complexity of electrical power systems is increasing. Consequently, the occurrence and the amplitude of the fault current are rising. This fault currents harm the substations’ electrical equipment. Besides, the growth in the fault current level is forcing the change of the circuit breakers to others with a higher interruption capability. A proposal to solve this problem is the fault current limiter (FCL). This equipment has low impedance in the normal operation and high impedance in a short circuit moment. Superconductors are an advantageous choice of material in this case, because of their properties. In order to simulate this equipment, the 2-D Finite Element Method (FEM) has been used. In this paper, a novel FEM simulation analysis of the saturated core Superconductor Fault Current Limiter (SFCL) is proposed using the A-V-H formulation. The current distribution in the superconducting coil is observed. The results are compared to the limited fault current measurements and simulations available in the literature.
