摘要
针对现有实践教学体系中创新型、综合性实验缺乏的情况,立足于高电压输电线缆供电问题,提出了基于最大功率跟踪的电流互感器取电电源设计的创新实验方案。实验融合了电路理论、高电压技术、控制理论等学科相关知识,通过实验选题背景、理论分析、算法应用、硬件设计、仿真分析5个阶段,使学生了解电流互感器取电电源理论模型,学习基于粒子群算法与扰动观察法结合的双重最大功率跟踪算法跟踪二次侧最大功率,掌握硬件电路设计方法,培养学生软件编程思维,通过仿真能直观得到最优结果,提高学生分析和解决实际问题的能力。
In view of the lack of innovative and comprehensive experiments in the existing practical teaching system,an innovative experimental scheme of the current transformer power supply design based on the maximum power tracking is proposed based on the supply of high-voltage transmission cables. The experiment integrates relevant knowledge of circuit theory,high voltage technology,control theory and other disciplines. It consists of five stages: topic selection background,theoretical analysis,algorithm application,hardware design and simulation analysis. Through these,students can understand the theoretical model of current transformer power supply,learn the dual maximum power tracking algorithm based on particle swarm optimization and perturbation observation method to track the maximum power of the secondary side,and master the hardware circuit design method. In addition,students’ software programming thinking is cultivated,so that the optimal results can be obtained intuitively through simulation,and students’ ability to analyze and solve practical problems is improved.
