摘　　要：“新能源发电技术”课程内容宽泛且抽象,前沿性和专业性极强、学习难度大。为了激发学生的学习兴趣和创新热情,进一步提升教学效果,基于ANSYS/Maxwell设计了海上风机雷电暂态虚拟仿真实验教学平台,开展相关实验教学工作。基于该实验教学平台,设计开发了3个实验:①搭建海上风机机舱、塔筒和接地体的等效电路模型,依托ANSYS/Maxwell搭建电磁暂态仿真模型,分析不同工况下的输出特性;②选取Heidler雷电流模型,利用偶极子法计算一次和二次雷击作用下整个风机内部的电磁场分布;③分析海上风机接地环境各层深度对塔筒内所产生的感应磁场大小的影响,通过实验验证雷电防护措施的必要性。The “Renewable energy power generation technology” course has the characteristics of extensive and abstract content,strong cutting-edge and high profession,and difficulty for learner.In order to stimulate students' learning interest,innovative enthusiasm and further improve the teaching effectiveness,a virtual simulation experimental teaching platform of offshore wind turbine under lightning transient on ANSYS/Maxwell is designed to carry out relevant experimental teaching work.Based on the experimental teaching platform,three experiments are designed and developed:①The equivalent circuit model of offshore wind engine room,tower and grounding body is built,and the electromagnetic transient simulation model is built based on ANSYS/Maxwell to analyze the output characteristics under different working conditions.②Heidler lightning current model is selected and dipole method is used to calculate electromagnetic field distribution of wind turbine under first and second lightning strikes.③The effect of each depth of grounding environment of the offshore wind turbine on inducting magnetic field of tower is analyzed,and the necessity of lightning protection measures is verified through experiments.
