摘 要: 当并网逆变器的输出与负载需求的功率相匹配时,被动式孤岛检测方法就会失效。介绍了带正反馈的有源频率偏移法检测孤岛效应的原理,讨论了该法可能存在的检测盲区,并基于此法在Matlab/Simulink 平台进行了系统的仿真验证。结果表明,该法检测孤岛效应迅速有效,对特定负载无检测盲区,达到了孤岛检测相关标准的要求。

Abstract: When the grid-connected inverter output power was equivalent to the power of loads, the passive islanding test might be ineffective. Introduction was made to the principle of active frequency drift (AFD) method with positive feedback to test islanding effect. This paper discussed the possible blind zone by AFD method and based on this method, simulation verification was carried out on Matlab/Simulink platform. The results show that the method to test islanding effect is fast and valid, without test blind zone for special load, to have reached requirements of related islanding test standard.
Key words: islanding test; photovoltaic; grid-connected inverter; active frequency drift method
