摘要
并网型PWM变流器,可广泛应用于新能源并网发电系统、变频驱动系统、有源电力滤波器和无功补偿装置等,是"电力电子技术"课程中三相PWM逆变电路的具体应用。本文在阐述三相PWM整流器与锁相环控制策略基础上,建立相关数学模型,并使用Matlab/Simulink仿真软件进行分析。仿真分析与演示丰富了教学内容,加深学生对PWM逆变电路内容的理解和掌握,使教学内容具体化,提高教学质量。
Grid-connected convertor is an essential part of Power Electronics Teachnology course. It can be widely used in new energy grid generation system, frequency conversion driving system, active power filter, reactive power compensation equipments. In this paper, the control strategies of three phase PWM converter and phase locked loop are described. Mathematical model, simulation and so on are elaborated. The results of simulation and analysis enrich the teaching content, deepen students＂ understanding of PWM rectifier, and improve the teaching quality.
