Bat-inspired algorithm is a metaheuristic optimization algorithm developed by Xin-She Yang in 2010. this is the demo of bat algorithm

用遗传算法求取函数的最大值。遗传算法的每一步骤都用子函数的形式给出。适合对遗传算法的入门级选手学习、参考。(Using genetic algorithms to strike a function of the maximum. Each step of the genetic algorithm is given in the form of a subfunction. Suitable for entry-level players genetic algorithm learning, reference.)

说明：  两个用于图像处理的Matlab工具箱，OMPbox10和KSVDbox13，由于后者是要求安装前者的，所以就打包一起发上来了，下载一次就够了。(Two Matlab toolbox for image processing, OMPbox10 and KSVDbox13。 Since the latter requires the installation of the former, so packed together, so download once is OK。)

With increasing wind penetration in power systems, many national grid codes will demand complete models and simulation studies under different system conditions in order to ensure that the connection of a wind farm will not have a detrimental impact on the network to which it will be connected. Hence a dynamic model with reduced-order double cage representation for the DFIG and its associated control and protection circuits has been developed. It was then used to simulate the response of wind turbine to network faults on a simple two busbar system.

介绍了 Cohen类双线性时频分布并针对交叉干扰项影响无法完全消除的问题进行了重排时频变换以提取及分辨 含有白噪声和窄带周期干扰的局部放电信号。处理仿真和现场检测到的局部放电超声信号时根据白噪声和窄带 周期干扰信号在时域上的平稳性特性发现重排 Cohen类时频变换方法不仅可以很好地将局放信号和背景噪声以 及窄带周期干扰信号分辨开来,而且大大减弱并抑制了交叉干扰项的影响,保持了更高的时频分辨率和时频聚集 性,从而验证了重排 Cohen类时频变换方法的有效性。 (In order to express the partial discharge ( PD) information of gas insulated switchgear ( GIS) in time-frequency domain, weintroduced theCohen? s class bilinear time-frequency distribution and its reassigned time-frequency transform method to pick up and distinguish theultrasonic signals in field from the whitenoises and narrow band periodic interference signals using the acousticemission ( AE) technology. After the processing of the simulated and PD ultrasonic signals in field, and according to the stationary feature of white noises and narrow band interference signals, wedraw a conclusion that the reassigned time-frequency distribution method can not only distinguish thePD signal from back ground noises and narrow band interference signals, but also decrease and restrain the influenceof cross-items, and acquire better time )
