Study in the Application of PSIM Software in the Teaching of Curriculums Related to the New Energy Power Generation

In view of the teaching requirements of the new curriculums about new energy power generation technology in electrical engineering field, this paper has proposed and designed a rated 3kW wind power system under the environment of PSIM9.0 software. Through systematically analyzing the mathematics and theory knowledge of the small and medium sized permanent-magnet direct-drive wind power system (PDWPS for short), the wind power system model has been built and the back-to-back double-PWM control circuit has been designed. Then the whole PDWPS has been established based on PSIM. The simulation results show that, when the wind speed changes, the output power of the generator is stable and the DC voltage of the inverter is constant. The results prove that the control strategy is correct and valid. As a powerful auxiliary teaching tool, PSIM can be used to strengthen student's understanding of theoretical knowledge and improve the students' learning interest and enthusiasm. The contents in this paper provide a new method to the teaching and practice in electrical engineering courses.
