In the study of crosstalk of multiconductor overhead transmission lines, the traditional model is often established on a perfectly conducting ground, ignoring the influence of the ground as a poor conductor on the transmission voltage and current. In this paper, the influence of being placed on the ground with a frequency-varying ground impedance loss is studied, and the contribution of ground impedance loss to crosstalk is added into the classical multiconductor transmission line (MTL) equation. For the parasitic parameters of overhead lines with insulating medium, a simple analytical method of hierarchical series method is adopted. According to the updated equation and the boundary condition derived by finite-difference time-domain (FDTD) method, the accurate crosstalk solution is obtained. In this paper, considering the influence of non-uniform medium and ground impedance loss and combining with MTL time-domain analysis method, the crosstalk can be calculated accurately, which is of great significance for the research on crosstalk of multiconductor overhead transmission lines.

Energy demand forecast has an important practical significance for the sustainable development of the national economy, the reasonable allocation of resources, and the construction of modernization goals. This study is based on the analysis of coal, electricity, natural gas, and other energy data in Yunnan Province from 2011 to 2018 and uses long short-term memory, sequence to sequence, deep learning, and ridge regression coupling methods to construct an energy demand forecast model in Yunnan Province. Forecast results show the following. The total energy consumption of Yunnan Province from 2021 to 2025 will continue to increase. Moreover, the coal consumption of Yunnan Province will continue to decline from 2021 to 2025. Furthermore, the electricity consumption of Yunnan will increase by about 8.02% year-on-year from 2021 to 2025. The experiment proves that the forecasting effect of the energy demand forecast model proposed in this study is excellent.
