为深入推进专业学位研究生培养模式改革,进一步提升电气工程专业学位研究实践与服务国家电力行业能力。文章提出了以培养学生的创造能力和实践能力为核心,以电力系统分析与计算课程为主要对象,探索案例教学法在该课程中的应用。案例教学作为一种新型的互动教学方法,是以教师为主导,学生为主体,将真实案例融入课堂中,有助于课程思政教育、提升课堂互动、促进产教融合和提升专业学位研究生的人才培养质量。To promote the reform of the professional degree graduate training mode, further enhance the research ability of electrical engineering professional degrees and the service ability of the national power industry. We propose to focus on cultivating students’ creative and practical abilities, with the course of power system analysis and calculation as the main object, and explore the application of case teaching method in this course. Case teaching is a new type of interactive teaching method centered on students. Integrating real cases into the classroom can help with ideological and political education, enhance classroom interaction, promote the integration of industry and education, and enhance the quality of talent cultivation for professional degree graduate students.
电动汽车充电桩运行时产生的谐波,在采用并联APF(active power filter)治理时,负载侧会产生谐波放大效应。该文提出改进APF检测跟踪策略,通过改进ip-iq检测与双重准谐振控制来精确补偿5、7次谐波,降低了谐波补偿率和改进APF拓扑结构,通过在负载侧并联无源滤波器,增大负载交流侧阻抗,两个方面来抑制充电桩负载侧谐波放大效应。仿真结果证明了改进方法的正确性。
