摘要
线损电量产生于发电、输电、配电及用电等环节,线损电量占供电量的百分比称为线损率。针对线损率预测问题,提出了一种基于对抗生成网络与BP神经网络的低压台区线损率预测模型。选取某市低压台区线损数据作为实验数据集,经数据预处理后,通过K-Means++算法将低压台区分类,对不同类别的低压台区分别训练对抗生成网络来增加不同类别的样本数据,利用不同类别样本数据分别训练BP神经网络搭建低压台区线损预测模型。实验结果表明,与传统BP神经网络模型相比,该预测模型具有更加准确的效果,通过对抗网络增加样本数据可以有效改善低压台区线损数据量偏小的问题。
The line loss energy consumption comes from power generation,transmission,distribution and power consumption,and the percentage of the line loss power in the power supply is called the line loss rate. Aiming at the problem of line loss rate prediction,this paper proposes a low-voltage transformer area line loss prediction model based on the generative adversarial networks and BP neural network. The line loss data of a low-voltage transformer area in a city is selected as the experimental data sets. After data pre-processing,similar low-voltage transformer areas are classified by K-Means++ algorithm,and different types of low-voltage transformer areas are trained to increase different types of data by different generative adversarial networks,Finally,different types of sample data are used to train BP neural network and construct a low-voltage transformer area line loss prediction model. The experimental results show that the prediction model proposed in this paper is more accurate than the traditional BP neural network model,and it shows that increasing the sample data by generative adversarial networks can effectively improve the problem of small line loss data quantity in the low-voltage transformer area.
