Liu Haoliang, a 2018 doctoral student in the research group of Professor Du Boxue from the School of Electrical Automation and Information Engineering (SEIE) at Tianjin University (TJU), was recently awarded the 2023 IEEE DEIS Graduate Student Fellowship, which is the highest honor for graduate students in the field of electrical insulation worldwide. This is the second time that students from the SEIE at TJU have won this honor, following the 2017 doctoral student Liang Hucheng.
This award was established and funded by the Dielectrics and Electrical Insulation Society (DEIS), which enables its winner to further explore a research topic in the areas of electrical insulation and dielectric phenomena. The evaluation process of the project comprehensively considers the importance and innovation of the research topic, as well as the research work foundation of the researchers.
Liu Haoliang conducts experiments on magnetic confinement fusion devices on site
This award is open to graduate students in the field of electrical insulation from around the world, and is generally submitted anonymously before the end of September each year. It is selected by the DEIS Education Committee through double-blind evaluation. Every year, 3 to 5 outstanding graduate students in the field of electrical insulation are selected worldwide, with a funding amount of $5000.
Certificate
The funded project from Liu Haoliang is "Space Charge Measurement of Polymer Dielectrics in Strong Magnetic Field Based on Current Integral Method ". Magnetic confinement fusion is the "ULTIMATE ENERGY" pursued by humans, and its insulation reliability is crucial for the safe and stable operation of nuclear fusion devices. However, existing methods cannot be applied to the strong magnetic field environment inside nuclear fusion devices, causing insulation defects not detected in a timely manner, leading to serious explosion accidents and economic losses. The project aims to analyze the dielectric response of insulation materials and invert and reconstruct the space charge distribution and transmission characteristics inside the dielectric.
Technical route of the funded project
The project is expected to fill the gap in strong magnetic field space charge detection technology, achieve performance assessment and evaluation of strong magnetic field insulation equipment, and promote the steady development of magnetic confinement fusion devices towards higher field strength and larger energy.
