本发明提出的一种深度并行柔性发射网络的电力终端指纹识别方法,结合附图详细说明如下:A power terminal fingerprint identification method of a deep parallel flexible transmission network proposed by the present invention is described in detail as follows with reference to the accompanying drawings:

图1是本发明方法的总体设计流程图。首先,从大量的电力终端设备中获取不同运行条件下的电压、电流波形,通过深度并行柔性发射网络对波形特征进行学习,实现介入新设备产生新波形后的电力终端指纹识别,具体通过以下步骤实现。Fig. 1 is the overall design flow chart of the method of the present invention. First, the voltage and current waveforms under different operating conditions are obtained from a large number of power terminal equipment, and the waveform characteristics are learned through the deep parallel flexible transmission network, so as to realize the fingerprint identification of the power terminal after the new equipment is involved to generate a new waveform. The specific steps are as follows. accomplish.

步骤S1,对需要进行学习的电力终端设备进行工况采集,将这些电力终端设备连接至电压和电流监测设备上,对其施加不同的工况,得到电力终端设备在不同工作条件下的电压和电流波形。对波形进行高频采集,并存储形成测试数据。Step S1, collect the working conditions of the power terminal equipment that needs to be learned, connect these power terminal equipment to the voltage and current monitoring equipment, apply different working conditions to it, and obtain the voltage and voltage of the power terminal equipment under different working conditions. current waveform. The waveform is collected at high frequency and stored to form the test data.

步骤S2,对步骤S1中高频采集到的电压电流数据进行处理,对其进行离散傅里叶分解运算,得到电压电流波形的各次谐波幅值和相位信息,对其整合形成一个4n的矩阵,即视为电力终端设备的指纹。由于在电网中负荷往往呈现近正弦波形特性,高次谐波含量逐渐降低,因此电力终端指纹矩阵可以合理弃值,忽略较高频率的分解值,提高后续步骤的运算速度。Step S2, process the voltage and current data collected by the high frequency in step S1, perform discrete Fourier decomposition operation on it, obtain the amplitude and phase information of each harmonic of the voltage and current waveform, and integrate them to form a 4n matrix. , which is regarded as the fingerprint of the power terminal equipment. Since the load in the power grid often presents a near-sinusoidal waveform characteristic, and the high-order harmonic content gradually decreases, the power terminal fingerprint matrix can reasonably discard the value, ignore the decomposition value of higher frequency, and improve the operation speed of the subsequent steps.

步骤S3,使用步骤S2处理的电力终端指纹数据对深度并行柔性发射网络进行训练,柔性发射网络是在麦卡洛克·皮特斯模型的基础上改进而来,它引入了新的仿生学原理,根据生物学对神经元的研究结果进行改进,将前馈通道的参数改进为2个,并引入了第3个参数来模拟神经元的记忆强度,改进后的模型有了更快的目标拟合速度和更高的拟合精度。在执行训练之前,首先应合理设置深度柔性发射网络的深度和迭代参数,深度学习的神经元个数应在3个以上,并使用并行计算对不同参数或深度的深度柔性发射网络模型进行训练。Step S3, use the power terminal fingerprint data processed in step S2 to train the deep parallel flexible transmission network. The flexible transmission network is improved on the basis of the McCulloch Peters model. It introduces a new bionics principle, according to Biology improves the research results of neurons, improves the parameters of the feedforward channel to 2, and introduces a third parameter to simulate the memory strength of neurons, the improved model has a faster target fitting speed and higher fitting accuracy. Before performing training, the depth and iteration parameters of the deep flexible emission network should be reasonably set, and the number of neurons in deep learning should be more than 3, and parallel computing should be used to train deep flexible emission network models with different parameters or depths.

柔性发射网络神经元框架包括两个前馈通道参数(w,v)、一个迭代记忆强度参数M,每个并行的深度柔性发射网络训练步骤具体包括如下步骤:The neuron framework of the flexible firing network includes two feedforward channel parameters (w, v) and an iterative memory strength parameter M.

After the complex number description of the feedforward function, The following feedforward process function will be obtained as
