基于BP神经网络的谐波计量误差分析软件

Software for Analyzing Harmonic Metering Error Based on BP Neural Network

利用BP神经网络建立了谐波对电子式电能表计量误差影响的数学模型 ,它反映了谐波功角与该误差间的非线性映射关系。基于该模型应用VC ++ net开发了误差分析软件并计算了某牵引站谐波数据 。

In order to analyze the influence of harmonics on electronic watt-hour metering error, in this paper, a nonlinear mapping mathematic model is established.; This method shows the relationship between harmonic power angle and electronic watt-hour's metering error by means of BP neural network. Based on the model. An analysis software of electronic watt-hour meter's harmonic metering error is developed using VC++.net. In the end, the software is tested on a real data of harmonics in a traction substation and it shows that the software is valuable in practical application.
