Abstract:To reduce the requirement of DC-biasing capacity and improve the biasing ability of a permanent magnet (PM), a novel hybrid saturated-core fault-current limiter (HSCFCL) is proposed in this paper. Compared with traditional saturated-core fault-current limiter (SCFCL), the HSCFCL has the advantages of small size, low DC-biasing capacity, a high biasing ability of the PM and excellent limiting performance. Firstly, the principle and the magnetic circuit model of the HSCFCL are introduced. Then, the improvement of DC-biasing capacity with a PM is analyzed. In addition, the influence of the leakage-flux effect on the biasing ability of the PM is presented in detail, and a small-section optimal structure is proposed to improve the biasing ability of the PM. Finally, to validate the principle and performance of the HSCFCL, various electromagnetic simulations, optimization studies and experiments are carried out. The simulation and experimental results demonstrate the effectiveness of the proposed method.

“…There are several traditional approaches to limiting the fault current, such as the air-core reactor, highimpedance transformer and network splitting. However, these approaches have some drawbacks [1]. The fault current limiter (FCL) has been one of the most promising methods to limit fault currents in power systems.…”

This paper presents a multi-objective Pareto optimal method for allocation of fault current limiters based on an immune algorithm, which takes into account two objectives of the cost and fault current mitigation effect. A sensitivity factor calculation method based on the rate of fault current mitigation is proposed to reduce the search space and improve the efficiency of the algorithm. In this approach, the objective functions related to the cost and fault current mitigation effect are established. A modified inversion operator based on equal cost is proposed to converge to global optimal solutions more effectively. The proposed algorithm is tested on the IEEE 39-bus system, and obtains the Pareto optimal solutions, from which the user can select the most suitable solutions according to the preferences and relative importance of the objective functions. Simulation results are used to verify the proposed method.

“…Superconducting FCLs are costly and need high maintenance requirements, and solid state FCLs are limited by rated power of semiconductor devices. Saturated-core FCLs (SFCLs) are widely analyzed and developed owing to its advantages, such as passive reaction to a fault, low cost and high reliability [4][5].…”

To reduce the requirement of DC-coil-generated magneto-motive force (DC MMF), this paper analyses the method of using permanent magnets (PMs) to saturate the core. In this paper, a novel bridge-type hybrid saturated-core fault current limiter (BHFCL) is proposed to investigate the influence of PM. For the BHFCL, a bridge structure is designed to guarantee fault clipping performance, with a fault limiting reactor. Also, the compact structure of magnetic device and the shared coil of AC and DC could reduce cost and losses. To compare the influence of PMs on the performance of BHFCL and validate the effectiveness of the proposed BHFCL, various FEA simulation models in a simple system are carried out by ANSOFT. Simulation results demonstrate that the BHFCL could achieve considerable energy consumption reduction with little effect on the normal condition voltage drop as well as fault clipping ability. The BHFCL is efficient in fault clipping and the performance is shown to depend mainly on the value of the reactor included in the bridge.Index Terms-Fault current limiter (FCL), permanent magnet, steel core, magneto-motive force (MMF).
