  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.)

    同相牵引供电系统旨在实现电能质量的综合补偿。提出了一种基于同步坐标变换的电流检测方法,能实时准确地检测 出负载电流的基波正序有功分量、基波正序无功分量、基波负序分量以及谐波分量,为综合补偿提供了基础。电能质量的补 偿力度与设备容量之间存在非线性关系。提出补偿度的概念,并给出补偿度与电能质量参数的关系,通过给定电能质量期望 参数,实时调整负序、谐波以及无功补偿度,使得综合潮流控制器容量在各电能质量补偿参数之间得到实时优化配置,从而 实现同相供电系统容量优化满意补偿。理论推导和仿真结果验证了所提方法的正确性和可行性。(The cophase traction power supply system aims at achieving power quality comprehensive compensation.A current detection method based on synchronous reference frame transformation is proposed.The method can decompose the load current real-timely into fundamental positive-sequence active component,fundamental positive-sequence reactive component,fundamental negative-sequence component and harmonic component,which lays a foundation for comprehensive compensation.There are nonlinear relation between compensation strength of power quality and device capacity.The paper proposes the concept of compensation degree and gives the relationship between compensation degree and power quality parameters.By giving expected power quality parameters,it adjusts compensation ratios of negative,reactive and harmonics instantaneously,so that the IPFC capacity can be allocated between power quality compensating parameters optimally and real-timely,thus achieving capacity optimal satisfactory compensa)

    说明:  Recent advances in the relevant technologies of contemporary wireless sensor nodes has motivated a growth in the deployment of wireless sensor networks (WSN) for commercial, non-commercial and research applications. In the aforementioned applications, it is often prudent to frustrate unauthorised wireless communications with WSN nodes.

    This paper presents a clustering approach which estimates the specific subspace and the intrinsic dimension of each class. Our approach adapts the Gaussian mixture model framework to high-dimensional data and estimates the parameters which best fit the data. We obtain a robust clustering method called High- Dimensional Data Clustering (HDDC). We apply HDDC to locate objects in natural images in a probabilistic framework. Experiments on a recently proposed database demonstrate the effectiveness of our clustering method for category localization.
