The Study of Shielded Wires’ Impact on Greenhouse Induction Electricity Under UHV AC Transmission Lines Based on the Maximum Information Coefficient

Due to the strong electric field near the Ultra High Voltage (UHV) transmission lines, there are increasing complaints about induced electrical problems in greenhouses near the lines. In this study, a model of a 1000 kV double-circuit AC transmission line and a steel-framed greenhouse was established to investigate the effects of different shielded wire parameters on induction electricity in the greenhouse. The simulation results were analyzed based on the maximum information coefficient. The study found that the correlation between different shielded wire parameters and induction electricity in the greenhouse was ranked from high to low as follows: installation height, the horizontal distance from the greenhouse, the number of shielding wires, and spacing between shielding wires. The installation height had a significant impact on the induction electricity value, while the correlation between the spacing between shielding wires and induction electricity was relatively low.
