The principles of controlled DC reactor fault current limiter for battery energy storage protection

The significance of battery energy storage systems (BESSs) technology has been growing rapidly, mostly due to the need for microgrid applications and the integration of renewables. Relevant to the importance of utilization of BESS in microgrids, the protection of the BESS during microgrid faults has become a concern too. The short circuit in...

Cost optimising design alternatives for the primary distribution system on Floating Liquid Natural Gas vessels

The global demand for natural gas is growing as gas is a cleaner partner to renewable energy than oil and coal. To be able to exploit remote offshore gas fields Shell is developing a floating facility to produce, treat and liquefy natural gas, called a Floating Liquid Natural Gas (FLNG) vessel. To make the FLNG vessel a cost effective option for...

3D Nonlinear transies field-circuit modeling of inductive fault current limiters

Due to increasing levels of fault currents, Fault Current Limiters (FCLs) are expected to play an important role in the protection of future power grids. Inductive saturable FCLs are particularly interesting due to their inherent reaction on the fault. Many different configurations have been proposed in literature. Being difficult or impossible...

Evaluation of changes required in the transmission system to facilitate developments of smart grids

This project is a study into the transmission network system setup of tomorrow in the Netherlands. This work was carried out at TenneT TSO and investigates the Network behavior in response to faults at various locations in the system and the influence of varying electrical generation and loads under four growth scenarios envisaged by TenneT in...

Novel Topology of Saturated-core Fault Current Limiter

Increasing levels of fault currents in utility grids are expected to result in mechanical and thermal overstresses of different power system components. To cope with these increased levels, expensive upgrades and replacements of currently employed Circuit Breakers might be required in the near future. Fault Current Limiters (FCLs) are expected...
