摘　　要：随着国家智能电网策略的实行,对应智能终端电能计量配套系统也逐步向多功能智能化发展,为此对电量预测模型和电量数据智能检测方面进行分析。建立电量原灰色预测模型,利用支持向量机拟合电量参数,并确定各项权重形成电量标准化模型。电量数据信号检测运用瞬时谐波参数估计法,将数字信号通过卷积运算获取相应带通滤波器的输出信号,在零频处对信号处理后得到对应的谐波分量瞬时参数,实验表明该方法可以提高电网运行效率。With the implementation of the national smart grid strategy,the corresponding intelligent terminal electric energy measurement system should be developed gradually towards the multi-functional intelligence,therefore,the electricity quantity forecasting model and electricity quantity data intelligent detection are analyzed. The grey prediction model of electricity quantity is established. The support vector machine is used to fit the parameters of electricity quantity,and determine the weight of each item to form the electricity quantity normalized model. The instantaneous harmonic parameter estimation method is used to detect the data signal of electricity quantity. The convolution operation is performed for the digital signal to acquire the corresponding output signal of the band-pass filter,and then the signal is processed at the zero frequency to get the instantaneous parameters of the harmonic component. The experimental results show that the technology can improve the operating efficiency of power grid.
