The course has implemented modular and multi-level teaching reforms. The course team has built a unique CIPE resource library to integrate ideological and political education organically into professional teaching, developed a differentiated process assessment system to precisely track students’ learning progress, and promoted cross-disciplinary integration to cultivate students’ comprehensive application and innovation abilities. The reform measures have achieved significant results, with students highly evaluating the integration of CIPE and the differentiated assessment methods. In the future, universities should further deepen teaching reforms, strengthen CIPE construction and interdisciplinary integration, comprehensively improve the quality of undergraduate education, and provide strong support for talent cultivation in the new era.展开更多

文摘提出一种模块化多电平变流器(modular multilevel converter,MMC)的自适应均压方法。在每个控制周期中,根据桥臂电流绝对值的大小选择不同个数的功率模块进行轮换。此外,还推导并计算了采用该自适应均压方法的功率器件平均开关频率的解析表达式。通过160 k V/400 MVA的MMC仿真系统验证了所提出的自适应均压算法的有效性和平均开关频率计算的正确性。最后,在RT-LAB实时仿真实验平台中搭建了350 k V/1000 MW的MMC背靠背系统,对上述方法进行了实验验证。实验结果表明,采用所提出的自适应均压方法能够在保证功率模块电容电压均衡的前提下降低开关频率,提高系统效率。
