随着燃料电池技术的迅速发展,越来越多的大功率级别燃料电池运用到分布式发电中.为了使燃料电池安全稳定运行,燃料电池分布式发电需要准确的检测出孤岛效应.运用主动移频式(AFD)孤岛检测方法对质子交换膜燃料电池(PEMFC)发电并网系统进行了检测,实验结果表明AFD法能有效的检测PEMFC发电并网系统孤岛的发生.
Along with the rapid development of the fuel cell technology, more and more high power fuel cell were used to distributed generation. Like many distributed generation technologies, accurate detection of the islanding effect was required by fuel cell distributed generation. The islanding method based on active frequency drift (AFD) was tested in proton exchange membrane fuel cell (PEMFC) power generation and grid-connected system, and the results and analysis were given. The results show that the occurrence of the PEMFC power generation and grid-connected system island can be effectively detected by AFD method.
