Graduate Program of Electrical Engineering 


Graduate Program of Electrical Engineering (Academic)

Electrical engineering is a subject that studies the generation, transmission, transformation and control of electric power involving its theory, method, technology and application in engineering. It combines electrical theory, electronic technology, control theory and information technology together. The field of electrical engineering at ZZULI covers all the sub-regions in electrical engineering, i.e. electric machines and electric devices, power system and automation, power electronics and electric drives, high voltage and insulation technology, electrical theory and new technology. The research work in the Department of Electrical Engineering at ZZULI is connected with many labs and research centers, such as the Henan Key Lab of Information-based Electrical Appliances (approved by the government of Henan Province), the Zhengzhou Engineering Center (approved by the municipal government of Zhengzhou), the Dynamic Simulation Lab of Power System, and the New Energy Lab. All of them are affiliated under ZZULI. The teaching staff in Dept. EE is professional and outstanding. Currently there are 19 full-time teachers, 7 of them are professors, 16 of them hold Ph.D. degrees, one is awarded as the National Role-Model, and 5 are elected as the Provincial Chief Academic Leaders of key discipline.
