直流微电网中的断路器研究,本文介绍了直流微网的基本概念，在直流微网基本模型的基础上加以模块具体细化，提出了一种合家用智能直流微网的架设结构，同时通过参考欧洲微网系统的标准，并依据已有文献对微网电压等级的优化对比，给出了合适的微网电压标准。在此基础上，介绍了一种基于直流母线电压信号（DBS）的直流微网的控制策略，包含新能源的变换器控制和储能装置的变换器控制。对于实现负载与直流母线的交互，本文以软开关技术为基础，提出了一种新型智能直流断路器拓扑，并通过仿真验证其工作原理，该断路器不仅可以实现零电流机械开关的拉断，还可以作为功率路由器的基础模块，实现能量路由的概念。(a study of DC breaker applied in DC microgrid)

仿真了地球杂波的情况。考虑了地球自转带来的多普勒旋转等影响。仿真结果和理论相一致。可作为星载雷达地球杂波仿真的参考(Clutter simulation in the case of the Earth. Taking into account the Earth' s rotation brought about by the impact of Doppler rotation. Simulation results and theoretical line. Can be used as space-borne radar clutter simulation of the Earth' s reference)

可以实现对大量数据的实时在线预测及其分类效果(The real-time online prediction and classification effect of a large number of data can be realized)

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.
