微电网保护问题与传统配电网保护有着极大的不同，典型表现在以下几个方面：a.微电网在并网运行和孤岛运行两种运行方式下，短路电流大小不同且差异很大。b.微电网中电源及相关负荷的接地方式对故障电流的大小影响也很大。c.加入分布式能源后，微电网的双向潮流特性对微电网保护的方向判别也有新的要求。d.发生故障时，微电网与配电网的不同隔离策略需要与微电网保护相结合，这也是微电网保护的关键。(The problem of microgrid protection is very different from that of traditional distribution network protection. Typical manifestations are as follows: a. The short-circuit current of microgrid varies greatly under the two operation modes of grid-connected operation and island operation. B. The grounding mode of power supply and related loads in microgrid also has a great influence on the magnitude of fault current. C. With the addition of distributed energy, the bidirectional power flow characteristics of microgrid also have new requirements for the direction discrimination of microgrid protection. D. When a fault occurs, different isolation strategies of microgrid and distribution network need to be combined with microgrid protection, which is also the key of microgrid protection.)

Awk 是一种非常好的语言，同时有一个非常奇怪的名称。在本系列（共三篇文章）的第一篇文章中，Daniel Robbins 将使您迅速掌握 awk 编程技巧。随着本系列的进展，将讨论更高级的主题，最后将演示一个真正的高级 awk 演示程序。 捍卫 awk (Awk is a very good language, at the same time have a very strange name. In this series (a total of three articles) in the first article, Daniel Robbins will quickly grasp your awk programming skills. With the progress of this series will discuss more advanced subject, and finally will demonstrate a real demonstration of advanced awk program. Defend awk)
