优秀论文及配套源码。电压暂降是动态电能质量问题中最受关注的热点之一。大量新型电力电子设备的广泛使用对电网电能质量的要求越来越高,而且电压暂降在电网中又具有一定的传播性。因此,无论从电网还是用户都迫切需要对电压暂降进行研究和治理。对电压暂降的检测是解决电压暂降的前提条件,故本论文主要对电压暂降的检测方法进行研究。
本文分析了国内外短时电能质量扰动检测的研究现状,并着重讨论了短路故障、感应电动机启动和变压器激磁三种电压暂降扰动情况下电压暂降的特性;在此基础上选择了基于S变换的短时电能质量扰动检测

能量检测法是一种比较简单的信号检测方法[1], 属于信号的非相干的检测, 直接对时域信号采样值求模,然后平方即可得到;或利用FFT转换到频域,然后对频域信号求模平方也可得到。它无需知道检测信号的任何先验知识,对信号类型也不作限制。
实际上,能量检测是在一定频带范围内作能量积累,如果积累的能量高于一 定的门限,则说明信号的存在;如果低于一定的门限,则说明仅有噪声。能量检 测的出发点是信号加噪声的能量大于噪声的能量。能量检测方法对信号没有作任何假设,是一种盲检算法。
此代码“利用FFT转换
