摘要
“新能源发电并网技术”具有内容广泛且抽象、前沿性和专业性极强、学习难度大等特点。为了激发学生的学习热情,进一步提升教学效果,基于PSCAD/EMTDC设计了光伏发电并网系统的虚拟仿真实验教学平台,以便开展相关实验教学工作。基于该实验教学平台,初步设计开发了3个实验:①依托光伏阵列的数学模型搭建电磁暂态仿真模型,分析不同工况下的输出特性;②根据增量电导法的基本原理,设计并实现光伏发电系统的最大功率跟踪策略;③在PSCAD/EMTDC中搭建光伏并网系统的实验模型,验证主回路设计的合理性和控制系统的正确性。
The “Renewable energy power generation and grid-connection technology” course has the characteristics of extensive and abstract content, strong cutting-edge and high professional, and difficulty to learn,etc. In order to stimulate students’ learning enthusiasm and further improve the teaching effectiveness, a virtual simulation experimental teaching platform based on PSCAD/EMTDC is designed for photovoltaic grid-connected system to carry out relevant experimental teaching work. Based on the experimental teaching platform, three experiments are initially designed and developed:(1)building an electromagnetic transient simulation model based on the mathematical model of the photovoltaic array, analyzing the output characteristics under different operating conditions;(2)designing and achieving the maximum power tracking strategy of the photovoltaic power generation system according to the basic principles of incremental conductance method;(3)building an experimental model of the photovoltaic grid-connected system in PSCAD/EMTDC to verify the rationality of the main circuit design and the correctness of the control system.
