摘要
微电网的稳定运行至关重要,而微电网系统中各设备的运行状况、电能质量都对微电网的稳定运行产生极大影响,所以对系统中电能质量、各设备运行状况的检测尤为重要。论述了微电网中电能质量及其并网设备检测装置的优缺点和发展现状,以及国内外并网设备检测规范和标准,介绍了微电网并网设备监测指标及其测试方法,总结了一些已经在工程中广泛应用的电能质量及并网设备监测平台的基本结构、软硬件组成,指出随着无线通信技术、传感技术的.高速发展,未来微电网检测平台的智能化程度将会越来越高。
Stable operation of microgrid is of vital importance,and because the operation status and power quality of all equipment in microgrid system have a great impact on the stable operation of microgrid,the detection of power quality and operation status of all equipment in the system is particularly important.In this paper,the power quality of microgrid and the advantages and disadvantages as well as the development status of the detection device for grid-connection equipment are discussed,the detection specifications and standards for grid-connection equipment home and abroad are analyzed,the monitoring indicators and testing methods of microgrid connection equipment are introduced and the basic structure,hardware and software composition of the monitoring platforms for some power quality and grid-connection equipment that have already been widely used in projects are summarized.Finally,it is pointed out that with the rapid development of wireless communication technology and sensing technology,the level of intelligence of the microgrid detection platform will become higher and higher.
