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.)

说明：  我们描述了所提出的方法对超声（US）信号的压缩多路复用的直接应用。该技术利用压缩多路复用器架构进行信号压缩，并依靠频域中US信号的联合稀疏性进行信号重建。由于换能器元件具有压电特性，因此可以获得有关US信号频率支持的准确先验知识，并且可以在联合稀疏算法中使用。 我们在数值实验中验证了所提出的方法，并显示了它们在秩次缺陷情况下相对于最新方法的优越性。我们还证明，与没有已知支持的重建相比，该技术可显着提高体内颈动脉图像的图像质量。(We describe a direct application of the proposed methods for compressive multiplexing of ultrasound (US) signals. The technique exploits the compressive multiplexer architecture for signal compression and relies on joint-sparsity of US signals in the frequency domain for signal reconstruction. Due to piezo-electric properties of transducer elements, accurate prior knowledge of the frequency support of US signals is available and can be used in joint-sparse algorithms. We validate the proposed methods on numerical experiments and show their superiority against state-of-the-art approaches in rank-defective cases. We also demonstrate that the techniques lead to a significant increase of the image quality on in vivo carotid images compared to reconstruction without known support.)
