Abstract

Ultra-high voltage (UHV) transmission lines are an important part of China’s power grid and are often surrounded by a complex electromagnetic environment. The ground total electric field is considered a main electromagnetic environment indicator of UHV transmission lines and is currently employed for reliable long-term operation of the power grid. Yet, the accurate prediction of the ground total electric field remains a technical challenge. In this work, we collected the total electric field data from the Ningdong-Zhejiang ±800 kV UHVDC transmission project, as of the Ling Shao line, and perform an outlier analysis of the total electric field data. We show that the Local Outlier Factor (LOF) elimination algorithm has a small average difference and overcomes the performance of Density-Based Spatial Clustering of Applications with Noise (DBSCAN) and Isolated Forest elimination algorithms. Moreover, the Stacking algorithm has been found to have superior prediction accuracy than a variety of similar prediction algorithms, including the traditional finite element. The low prediction error of the Stacking algorithm highlights the superior ability to accurately forecast the ground total electric field of UHVDC transmission lines.
