Masdar Institute’s new ‘fault ride through’ system receives patent




The Masdar Institute of Science and Technology, an independent, research-driven graduate-level university focused on advanced energy and sustainable technologies, on Wednesday announced that a new fault ride through (FRT) transient management system, which can support the electric power grid during grid faults, developed by a team of its researchers has been issued a patent by the United States Patent and Trademark Office.
The patented fault ride-through (FRT) system and transient management scheme, developed by
Dr Mohamed El Moursi, Associate Professor of Electrical Engineering and Computer Science, Dr. Weidong Xiao, Associate Professor of Electrical Engineering and Computer Science and Po Hsu Huang, Electrical Power Engineering MSc alumnus, responds to the need to maintain uninterrupted electrical power supply. Maintaining a constant supply of electrical power is critical to modern day life. Even a temporary stoppage of power can lead to monetary setbacks, health risks, and lost data, which is why maintaining grid performance and reliability is a priority worldwide.
The technology was designed in particular to enable grid-connected wind farms to ride through all types of grid faults. However the technology also has potential applications beyond wind energy system, including as a high-voltage direct-current transmission system based on voltage source converter, which helps to achieve smooth power delivery to grids during grid faults.
