关于DFIG的低压穿越能力的研究。对以后实现低压穿越做一些探索性的工作(Along with the sharp increase in the proportion of wind power supply some areas the impact of Large-scale wind farms for the stability of regional power grid is more significant. The research on low voltage ride-through (LVRT) of wind power system based on doubly-fed induction generators (DFIG) becomes a hot issue. In this paper ,Firstly introduces the concept of low voltage ride-through technology, The standards of LVRT of some European countries are presented, And then analyses and compares the kinds of common realize low voltage ride- technology and improve control strategy. The transient characteristics of DFIG when the grid voltage sagging.)

传感器网络由大量能量有限的微型传感器节点组成.因此,如何保证在足够覆盖监测区域的同时延长网络的寿命,是一个需要解决的重要问题.为了达到这一目标,一种广泛采用的策略是选出部分能够足够覆盖监测区域的节点作为工作节点,同时关闭其他冗余节点.提出了一个数学模型,使得只要已知监测范围和节点感知半径的比值,就可以计算出达到服务质量期望所需要的节点数量.需要指出的是:与大部分研究覆盖的文献不同,该研究不基于节点的位置信息,因此可以极大地降低硬件成本,并且减少节点获得和维护位置信息的开销.模拟实验结果表明:在随机部署条件下,服务质量期望与实验所得到的实际覆盖度的误差不大于服务质量期望的2％ 而对于相同的服务质量期望和实际覆盖度,计算所得的工作节点数量与实验所得的工作节点数量的误差小于计算数量的5％,这表明推导出的节点数量与服务质量期望之间的关系与模拟实验的结果相吻合.该结果可以广泛应用于传感器网络的节点部署、拓扑控制等领域中.()

说明：  虚拟仪器代表着目前测试仪器领域的发展方向，LabⅥEw语言是一种功能强大的仪器开发平台。对淹没在噪声中声发射信号的有效提取(去噪)是声发射信号处理技术的第一步，也是声发射信号处理的关键所在。本文介绍了基于小波变换的阈值去噪方法。在LabⅥEw平台上，通过仿真试验，对声发射信号的几种阈值法的去噪结果进行比较，选出一种适合声发射信号去噪的阈值准则。(Virtual instrument on behalf of the current developments in the field of testing equipment direction, Lab Ⅵ Ew language is a powerful development platform apparatus. Submerged in the noise of the acoustic emission signal in the effective extraction (denoising) is the acoustic emission signal processing technology, a first step, the acoustic emission signal processing is the key. In this paper, based on wavelet transform thresholding denoising method. Lab Ⅵ Ew in the platform through the simulation of acoustic emission signals of several denoising threshold method for comparison of results to elect a suitable acoustic emission signal de-noising threshold criteria.)
