Research on exploratory photovoltaic power generation simulation experiment based on PSIM

光伏发电是“新能源”这一新工科专业的重要方向,具有工程实践性强的特点。受制于大规模铺设光伏电池板的客观困难以及光伏发电自身的随机性、不稳定性等问题,实验教学活动较难开展。将PSIM仿真软件引入光伏发电实验教学中,可以更快地帮助学生将光伏发电技术的理论知识转换为工程应用能力,并利用该平台提升学生创新实践水平。以光伏发电系统中电池板特性、最大功率跟踪算法、功率变换等核心问题为例,介绍PSIM在探究型光伏发电仿真实验中的应用。实践表明,采用PSIM仿真软件可以有效激发学生的学习兴趣,提高学生实践创新能力。

Photovoltaic power generation is an important direction of the new engineering major of“new energy”,and it has the characteristics of strong engineering practice.Subject to the objective difficulties of large-scale installation of photovoltaic panels and the randomness and instability of photovoltaic power generation itself,it is difficult to carry out experimental teaching activities.The introduction of PSIM simulation software into the experimental teaching of photovoltaic power generation can help students convert the theoretical knowledge of photovoltaic power generation technology into engineering application capabilities more quickly.And students’innovative practice level can be improved by the simulation platform.This paper takes core issues such as panel characteristics,maximum power tracking algorithm,and power conversion in photovoltaic power generation systems as examples to introduce the application of PSIM in exploratory experiments.Practice shows that the use of PSIM simulation software can effectively stimulate students’interest in learning and improve students’practical innovation ability.
