摘要
微电网主要由分布式电源、能量转换装置、负载以及监测和保护装置构成的小型电力系统。实验微电网可以在实验室模拟微电网的常见运行工况,支持研究和实验用。传统的微电网实验系统由于电压高、容量大、成本高等问题,不便于学生实操使用。本文首先对实验室微电网的研究现状进行分析,其次对所设计实验室微电网拓扑结构、实现功能以及保护设计等内容进行研究,最后给出仿真和实验结果。该系统也可作为工程研究的实验培训平台。
Microgrid is a small power system mainly composed of distributed generation,energy conversion device,load,monitoring and protection device.The experimental microgrid can simulate the common operating conditions of microgrid in the laboratory to support research and experiment.The traditional microgrid experimental system is not convenient for students to operate because of its high voltage,large capacity and high cost.Firstly,this paper analyses the research status of laboratory microgrid,then the topology,implementation function and protection design of laboratory microgrid were studied,and finally the simulation and experimental results were given.The system can also be used as an experimental training platform for engineering research.
