Abstract Utility engineers faced with the challenges of integrating new generation into existing power systems, clearing faults more quickly or finding an alternative to SF6 breakers will soon have a new product to meet all of their needs: a solid state current limiting circuit breaker. Electric utilities have long wished for a practical, reasonably priced, solid state circuit breaker which cou...

Increasing the short circuit current due to the penetration of distributed generations (DGs) in various voltage levels and meshed topology is a basic problem in power systems. Using fault current limiter (FCL) is an efficient approach to mitigate the exceeded short circuit levels. In this paper, a new approach is presented for multiple FCLs locating to decrease short circuit levels in meshed ne...

This letter develops an equivalent circuit model of a grid-forming (GFM) converter with circular current limiter and analyzes its transient stability. It is revealed that the inner control loop can be simplified as voltage source behind resistor. Based on developed model, theoretical analysis experimental tests demonstrate stability <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML"...

This paper proposes a parallel-resonance bridge type fault current limiter (PRBFCL) to augment the transient stability of a hybrid power system consisting of a photovoltaic (PV) power generation source, a doubly-fed induction generator (DFIG)-based wind energy system, and a synchronous generator (SG). The PRBFCL is designed such a way that it can provide sufficient damping characteristics to th...

In this paper, short circuit analysis, based on the electromagnetic transient program (EMTP), has been used to investigate the behavior of the DC reactor type FCL installed in an electrical distribution grid. System studies show that the DC reactor type FCL can not only limit the fault current to an acceptable value, but also can mitigate the voltage sag. A DC reactor type fault current limiter...

We report experimental control of chaos in an electronic circuit at 43.9 MHz, which is the fastest chaos control reported in the literature to date. Limiter control is used to stabilize a periodic orbit in a tuned collector transistor oscillator modified to exhibit simply folded band chaos. The limiter is implemented using a transistor to enable monitoring the relative magnitude of the control ...
