摘要
直流配电系统便于实现分布式电源的消纳和直流负荷的供电,在分布式电源与直流负荷发展较快的当今具有较大的发展空间。为使学生对直流配电系统有一个较为直观、全面的认识,进一步提升教学质量,同时提高学生的仿真建模能力,设立了直流配电系统仿真实验教学资源。该实验基于电磁暂态仿真软件PSCAD/EMTDC实现,依照选定直流配电系统的拓扑结构完成系统参数、关键设备设计以及模型搭建。正常运行和负荷投切的仿真实验结果表明,搭建的直流配电系统模型可靠且有效。该仿真实验能较好地贴近实际的直流配电系统示范工程,可为直流配电系统的理论教学提供仿真案例,提升教学效果。
Use of DC distribution net will take easy of connecting distributed generator and supplying power to DC load, and it has large development space in today’s rapid development of distributed generator and DC load. In order to enable students to have more intuitive and comprehensive understanding of the DC distribution system,further improve the teaching quality, and improve the students’ simulation modeling ability at the same time, the teaching resource of the simulation experiment of DC power distribution system is constructed. The experiment is based on the electromagnetic transient simulation software PSCAD/EMTDC, system parameters, key equipment design and model building are completed according to a selected topology of DC distribution system. Simulation results of normal operation and load switching show that the DC distribution system model is reliable and effective.The simulation experiment is closing to actual DC distribution system demonstration project, and it can provide a simulation case for the theoretical teaching of DC power distribution system, so as to improve the teaching effect.
