“…SCFCL's in theory should be able to limit the fault to a specific level continuously if thermal requirements are still met [17]. The prospective peak fault current in Figure 27 is shown to reach 50 kA with steady-state fault current to be approximately 25 kA.…”

“…The SCFCL is forced to operate immediately and limit the fault current as desired. The test shows the SCFCL's ability to recover from multiple faults quickly and provide automatic support to the system [17]. Zenergy Power has developed a smaller more compact SCFCL based on the information gain from the initial design.…”

“…Zenergy Power has developed a smaller more compact SCFCL based on the information gain from the initial design. This "Compact" design reduces the size, weight and cost without losing any operational functionality [17]. Figure 29, shows the new compact design of the SCFCL from Zenergy Power.…”

“…For a sinusoidal wave, the flux in the core will change from positive to negative per half cycle. The average rate of change of flux per cycle is given by equation (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17).…”

This dissertation presents a new hybrid fault current limiter (FCL) topology that is primarily intended to protect single-phase power equipment. It can however be extended to protect three phase systems but would need three devices to protect each individual phase. In comparison against the existing fault current limiter technology, the salient features of the proposed topology are: a) provides variable impedance that provides a 50% reduction in prospective fault current; b) near instantaneous response time which is within the first half cycle (1-4 ms); c) the use of semiconductor switches as the commutating switch which produces reduced leakage current, reduced losses, improved reliability, and a faster switch time (ns-µs); d) zero losses in steady-state operation; e) use of a Neodymium (NdFeB) permanent magnet as the limiting impedance which reduces size, cost, weight, eliminates DC biasing and cooling costs; f) use of Pulse Width Modulation (PWM) to control the magnitude of the fault current to a user's desired level. g) experimental test system is developed and tested to prove the concepts of the proposed FCL.This dissertation presents the proposed topology and its working principle backed up with numerical verifications, simulation results, and hardware implementation results. Conclusions and future work are also presented.ii DEDICATION

“…These equipments have a low resistance against the line current in the normal states and suddenly represent a large resistant against the current when a fault is occurred. In the past two decades, discovering High-Temperature Superconductors (HTS), several circuits for limiting the fault current such as the resistive HTS FCL, inductive FCLs, asymmetric flux, and saturated-core have been presented [2][3].…”

-The Active Superconducting Current Controller (ASCC) is a new type of Superconducting Fault Current Limiters (SFCL) which can limit the fault current in different modes. It also has the particular abilities of compensating active and reactive powers for electrical networks. In this paper, it is confirmed that the performance of ASCC in different operating modes introduces a limiting impedance in series with the network which can even degrade the transient stability and the operation of the Over-Current Relays (OCR) employed in a power system. In addition, the model of a three-phase ASCC is simulated, and the effect of descriptive modes on the current limiting level is investigated. For the transient stability analysis, a single machine-infinite bus system is tested, and the effect of operation modes is studied based on an equal area criterion obtaining the critical time and the critical angle. Modifying the setting parameters of OCR such as time dial and pick-up current, the protective coordination is also studied in different operating modes.

Part 14: Energy: SimulationInternational audienceSuperconducting fault current limiters are considered as emerging devices for the advent of modern power grids. Those limiters as well as other electric power grid applications have been developed in the last years in order to support the increased penetration of dispersed generation. The development of such limiters requires new design tools that allows to simulate those devices in electrical power grids with different voltage ratings and characteristics. This work presents a methodology to simulate the behaviour of saturated core type limiters based on its characteristic curves. A prototype is tested to obtain its characteristic and then the methodology is implemented in Simulink. The simulation carried out by the proposed methodology is compared with a real test
