VRGIS 3D simulation system for power grid soil and water conservation

This paper proposes a three-dimensional simulation system based on a virtual reality geographic information system (VRGIS) for optimizing the environmental adaptability of power grid soil and water conservation and transmission lines. The system integrates GIS and virtual reality technology and provides scientific decision-making support for power grid construction through three-dimensional visualization and intelligent optimization algorithms. This paper proposes a multi-objective optimization model based on soil and water conservation and power grid demand and combines GA and PSO to optimize the coordination of soil and water conservation measures and power grid construction. The experimental simulation results show that in a particular actual case, the soil and water conservation measures after the optimization algorithm reduce the soil erosion rate by 15%, while the power grid construction cost is reduced by 8%. At the same time, the system simulates the soil and water loss under different precipitation conditions through virtual simulation, which further verifies the model's accuracy and the system's feasibility.
