March 12，The School of Electrical Engineering successfully held the 25th "Expert Forum" academic lecture series in Classroom 5202, Xinglongshan Group Building。Associate Professor、Graduate tutor Zhong Hui was invited to be the keynote speaker，Students of all years in the School of Electrical Engineering actively participated。

Zhong Hui starts from the development of the Institute of Electrical Theory of Shandong University，Brief introduction to various topics such as the magnetic levitation artificial heart pump that he is currently responsible for。Afterwards，She is coupled from transformer multiphysics、Details the development and optimization project of offshore transformers in terms of partial discharge and stress analysis。

Zhong Hui pointed out，The available wind energy at sea is far more abundant than on land，But high humidity at sea、The special operating environment with high salt density has a great impact on the normal operation of wind turbine transformers。To solve the problem，Zhong Hui leads the team to establish an electromagnetic and thermal coupling model，Determine the temperature distribution within the transformer and calculate losses，Control the error within a smaller range，Use noise to determine stress at the same time，Then analyze the distribution of magnetic field，Improve system accuracy。Benefited from the above measures，Zhong Hui and his team have achieved great results in the research of offshore wind turbine transformers。final，She answered students’ questions about the scientific research process and other aspects。

This lecture enriches electrical students’ understanding of offshore wind turbine transformers，Broadens the students’ horizons，While creating a positive academic atmosphere，It has a good promoting effect on encouraging scientific research and innovation。
