A New GIS Based Material Estimation Method of Out-Building Transmission Construction at Low-Voltage Distribution Grid for Supplying New Power Consuming Capacity

sWith the rapid development of the power industry, traditional manual methods for out-building transmission construction at low-voltage distribution grid, which heavily rely on human intervention, are unable to meet the industry{\prime}s needs due to issues such as outdated data and inefficient resource allocation. To address this, this paper introduces a material estimation method of out-building transmission construction at low-voltage distribution grid. This method utilizes trajectory coordinate information recorded by Geographic Information System (GIS) devices to optimize and match the linear equation system of wiring paths in specific out-building scenarios. By analyzing the trajectory coordinates, the detailed wiring paths for transmission construction applications are determined, followed by material estimation for the entire project. Numerical studies on four Out-Building trajectory scenarios validate the feasibility of the proposed material estimation method of out-building transmission construction at low-voltage distribution grid. Comparative experiments with traditional method demonstrate the superiority of the proposed method.
