中文摘要: |
“双碳”战略下,新能源装置广泛接入电网时常面临阻抗失配与小信号失稳的挑战。掌握精准且实用的变换器建模与阻抗分析方法对于“新工科”专业人才十分重要。针对“电力电子技术”课程中阻抗分析章节理论公式多、动手实验少导致的教学内容抽象问题,从测量平台等方面进行教改实践,促使学生理解并掌握变换器建模与阻抗分析方法。旨在增强面对实际阻抗设计与匹配时的思维能力。 |
英文摘要: |
To achieve the carbon peaking and carbon neutrality goals, new energy devices are widely connected to the power grid, which creates impedance mismatch and small signal instability problems. Aiming at the lack of suitable experiments for the DC/DC converter dynamic modeling and impedance analysis, this paper explores a novel experimental platform design and corresponding analysis method. It not only guides students to understand the application of dynamic modeling, but also grasp the impacts related with parameters, measurement and algorithm. Finally, the impedance design and matching research capability in practical project get enhanced. |
