为了保证配电网稳定运行，对容易受雷击影响的配电网提出一种包含小波分析与信息熵的小波能量熵雷击故障识别方法和一种基于互相关算法的雷击定位方法。基于标准双指数函数模型、Heidler 函数模型和 IEEE的氧化锌避雷器模型，使用 PSCAD/EMTDC软件对配电网中的雷击故障与普通故障进行仿真，首先使用小波算法进行故障识别，然后使用相关算法进行雷击定位。仿真数据验证了两种方法可以准确有效地识别与定位雷击故障。

For ensuring stable operation of power distribution network,this paper proposes a kind of wavelet energy entropy lightning stroke recognition method containing wavelet analysis and information entropy and lightning stroke positioning method based on cross correlation algorithm for power distribution network which is easy to be affected by lightning stroke.On the basis of standard double exponential function model,Heidler function model and IEEE zinc oxide arrestor model,it applies PSCAD/EMTDC software for simulating on lightning stroke failures and common failures in power distri-bution network.It firstly applies wavelet algorithm for failure recognition and then correlation algorithm for lightning stroke positioning.Simulation data verifies that these two methods are useful to correctly and effectively realize lightning stroke failure recognition and positioning.
