Graduate students should complete all kinds of compulsory credits during their stay in school and complete research projects under the guidance of their tutors. Postgraduates will systematically cultivate and train their scientific research ability. Cultivate graduate students' scientific research ability and engineering practice ability, cultivate graduate students' creative thinking and innovation ability in scientific research, and have the ability of independent research and development. Can be engaged in scientific research and teaching in the field of electrical engineering.
In the long-term theoretical teaching, postgraduate training and scientific research practice, this subject has always been the foundation of electrical information majors. After several generations of predecessors' unremitting cultivation and efforts, research has been carried out around the key technical issues of this discipline, such as motors, transmission systems, control equipment, new energy and energy-saving technologies, and closely combined with the demand of local economic development in Jilin Province for on-the-job graduate students, seven stable research directions have been formed:
1. research direction of digital drive control and power saving technology: mainly study the signal detection technology, data processing method and system composition of intelligent control AC DC speed regulation system, servo system, electric traction system and motion control system, and the practical application of power saving control technology.
2. Research direction of servo control and tracking technology: mainly study the control theory, method and application technology of new power electronic devices, PWM power drive source composed of IGBT, computer control of digital power drive system, and power electronic energy-saving conversion technology. It is an interdisciplinary subject that integrates the latest achievements of electromechanical energy conversion and electromechanical integration equipment.
3. Research direction of power conversion technology and new energy development: engaged in new power conversion circuit design, development and utilization of wind, light and electric new energy, motor vehicle inverter control technology, multilevel inverter device, filter compensation and grid-connected switch control, power grid operation protection technology and energy-saving management system research.
4. Research direction of transmission system modeling and intelligent optimization control: modern control theory, sensor fusion technology and integrated comprehensive energy-saving method are adopted to engage in comprehensive measurement and control of production process objects such as machinery, electric vehicles, rail transit and program-controlled equipment drivers, process system identification, model establishment, control system design, prediction analysis and energy-saving optimization.
5. Wind-solar hybrid power generation and grid-connected technology: study the technical problems related to grid-connected operation of wind-solar hybrid power generation, that is, study the influence of adding wind-solar new energy devices to grid-connected power generation on the power flow distribution, power quality and stability of the whole system. Study the generation and operation planning method that can consider the characteristics of wind power, re-evaluate the power generation reliability of the system, analyze the capacity reliability of wind power, and study new reactive power dispatching and voltage control strategies.
6. Micro-motor and its control: mainly study servo motor, tachogenerator, stepping motor, synchro, resolver, permanent magnet brushless DC motor, single-phase AC series motor, doubly salient motor, linear motor, ultrasonic motor and their drive control system.
