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.)

滚球游戏意智游戏 问题描述 有八个小洞，序号和分布位置如图。小球从A、B、C（即洞号0、1、2）三个位置之一滚下。如果洞的状态为0时，球向左滚；如果洞的状态为1时，球向右滚。凡是球滚过的洞，状态取反（既由1变0，由0变1）。 现用8位二进制数依次从左到右表示八个小洞的状态。 例： 图中的初始状态为 00000101 时，最多滚入3个球时有 从C洞滚入一小球状态为 ――――＞ 00101111 从B洞滚入一小球状态为 ――――＞ 01111011 从A洞滚入一小球状态为 ――――＞ -bowls game Italy-game description eight holes and serial number and distribution figure. Small ball from the A, B, C (hole No. 0,1,2), one of the fallen three locations. If the state of the hole 0:00 a.m., the ball rolling left; If the state of the hole 1:00, the ball rolling right. Whatever strain at the hole, from the anti-state (both from a variable 0, 0 Variable 1). Now with eight followed by the binary number eight hole, said whatever the state.
