It is widely known, that the power industry plays an important role in the progress of the society. Faculties at the Department of Electrical Engineering of Tsinghua University have an unusually high involvement with the power industry, to meet its ever increasing demand. Centered around the subjects of ‘Safe, Economical and Environmental Friendly’, the Department has participated in numerous great national projects and also taken part in research work on the basic theory and key technology. With the achievements of the research, the Department has also undertaken the industrialization of the research results. In the respect of the research funding, as an important group in China, the Department has been funded by many high-level projects each year. Several of them are promoted by the national government. It can be seen from this point that, firstly, faculties have the ability to take part in the key research work, and secondly, the state and main power companies have confidence in the research quality of the Department of Electrical Engineering at Tsinghua University.
