## Sample Detailed Section (Excerpt from Chapter 3):

### 3.1 Transforming the Energy Sector According to the National Energy Administration’s 2021 “Technical Guidelines for Power Grid Drone Inspection,” DJI’s Matrice 300 RTK has been designated as the recommended model. Equipped with the Zenmuse P1 photogrammetric camera, it can generate high‑precision 3D models of 20 km of 500 kV transmission lines in a single flight, achieving centimeter-level accuracy. Test data from one provincial power grid indicate that tasks traditionally requiring five workers three days to complete can now be finished by a drone crew in just two hours, while defect detection rates have improved by 40%.

In the solar sector, DJI has partnered with LONGi Green Energy to develop an intelligent diagnostic system that combines visible-light and infrared multispectral scanning to automatically identify 12 types of faults, including hotspots and hidden cracks in solar panels. Following implementation at a 200 MW photovoltaic plant in Xinjiang, annual revenue losses were reduced by approximately RMB 2.7 million.

## Suggestions for Expansion: 1. Include specific case studies: select 3–5 representative user interviews 2. Add data visualizations: endurance comparison charts/inspection accuracy comparison graphs 3. Incorporate policy analysis: evolution of national airspace regulations 4. Elaborate technical details: provide a more thorough explanation of RTK positioning principles 5. Conduct economic feasibility analyses: ROI modeling frameworks
