IEEE-1547 问题请教
各位，我一直在看微网和分布式电源的文章，大多数都提到了IEEE 1547，也都说：当系统故障时，分布式电源必须退出运行，但是，我在IEEE 1547中没有扫到有这类似的语句，毕竟英文太长了。而且，IEEE1547有很多版本了，1547-2003、1547-2005、1547-2006、1547-2008、1547-2011。这还是成稿，如果是样稿/草稿，版本更多。我想请教这原文在哪一个版本哪一页哪一段出现的，给出小标题也行，非常感谢！ 95页，Islanding 这一章就有讲到。
To prevent islanding, a DR unit operating in parallel with the Area EPS should disconnect from the
system within 2 seconds of sensing a voltage sag or discontinuity of service on Area EPS side of the PCC.
This is typically fast enough to allow disconnection prior to the shortest reclosing times found in
protective relays on the Area EPS. It should also prevent reclosure into an out of phase DR unit, as well
as allow the fault arc to deionize prior to reclosure. Once a DR unit has disconnected from the Area EPS,
it should not reconnect into a de-energized system 对了，查的2006版，随便翻了翻，看得不仔细，楼主再仔细看看吧。 我看的是1547-2006 第4.2节 当系统出现异常（电压，频率异常）时，微电源需要退出的响应时间要求。
