PhD student Roya Nikjoo has received the High Voltage Association Student Excellence Award of 2016. The award was presented at the IEEE International Power Modulator and High Voltage Conference in San Francisco, United States in July.
Sweden’s top proponent of smart grid technology, Lina Bertling Tjernberg, has dedicated her career to analysing the reliability of electric power systems, mainly focusing on the grid. This is no easy task, especially given the rapid advance of technology and the changing nature of energy during the last 15 years.
Researchers don’t like them, nor do power companies. They are seen as disturbances in the power grid. But lightning and other natural high voltage currents are inevitable. Roya Nikjoo has exploited this fact to enable online diagnoses of power transformers. The innovative method landed her the international “Young Researcher Award” in high voltage engineering.
Smart grids are fundamental to allow increasing amount of renewable energy in the network. A much more flexible grid is also required in order to generate and transport solar energy from the Sahara to Sweden and connect more distributed generators. Researchers at KTH have contributed to the development of an eagerly awaited high voltage direct current (HVDC) circuit-breaker, which is essential to transmit renewable energy over long distances.
Andrés Alayón Glazunov combines signal processing and electromagnetic theory in his research. The result? He has discovered physical limitations on the antenna gain patterns in wireless propagation channels. The findings will contribute to enhancing multiple antennas, MIMO, used in communications, sensor and radar system, which among other things enables ultra-high spectral efficiency required in 4G and beyond wireless systems.
14 industry-sponsored master projects in controllable and intelligent power components for electric grids will give students the opportunity to apply their engineering skills in an industrial context. By tying academia and industry closer to each other, EIT InnoEnergy gives students better hopes for employment upon graduation.
With magnetic cooling, environmentally hazardous freon gas and other cooling agents can disappear from our fridges. David Jiles is coming to KTH to talk about material for magnetic cooling as well as material that can, among many other talents, independently set the focus on cameras and reduce vibrations in cars. However his magnetisation model has now received a challenge from doctoral students at KTH.
