摘　　要：为解决因用电数据缺失造成的电量失衡问题,确保重构后的中频感应加热设备能够保持相对稳定的运行状态,设计基于压缩感知的中频感应加热设备边缘用电数据缺失重构方法。对用电数据样本进行两次转化处理,得到电信号稀疏变换结果,通过构建压缩矩阵的方式,描述中频感应加热设备边缘用电数据的失稳现象,求解基于压缩感知的中频感应加热设备边缘用电数据脆弱性函数。设置电网网格结构,按照缺失数据的自编码形式,计算连续重构阈值指标的取值范围,完成压缩感知下中频感应加热设备边缘用电数据缺失重构方法的设计。实验结果表明,数据缺失区域内的最大电压数值只能达到30.0 V,电网主机可以根据实时电压的不同,确定缺失数据所处区间,对于解决电量失衡问题、增强重构后电网的运行稳定性可以起到促进性影响作用。In order to solve the power imbalance problem caused by the loss of power consumption data and ensure that the reconstructed intermediate frequency induction heating equipment can maintain a relatively stable operating state,a reconstruction method based on compressed sensing for the loss of power consumption data at the edge of intermediate frequency induction heating equipment is designed.The power consumption data samples are converted twice to obtain the sparse transformation result of the electrical signal.By constructing a compression matrix,the instability phenomenon of the edge power consumption data of the intermediate frequency induction heating equipment is described,and the vulnerability function of the edge power consumption data of the intermediate frequency induction heating equipment based on compressed sensing is solved.Set the grid structure,calculate the value range of the continuous reconstruction threshold index according to the self coding form of missing data,and complete the design of the reconstruction method of the edge power consumption data missing of the intermediate frequency induction heating equipment under compressed sensing.The experimental results show that the maximum voltage value in the area with missing data can only reach 30.0V.The power grid host can determine the interval where the missing data is located based on different real-time voltages,which can play a promoting role in solving the problem of electricity imbalance and enhancing the operational stability of the reconstructed power grid.
