Why is simulation training essential for drone-based power line inspections?
Accident Case 1: On May 25, 2025, in Chengde, Hebei Province, China, a power utility worker conducting a wind turbine inspection encountered strong winds, causing the drone to lose control and crash.
Accident Case 2: On July 14, 2025, in Luohe, China, a drone operator performing pesticide spraying accidentally entangled the drone with high-voltage power lines due to operational error.
Proper simulation training is essential before pilots perform real-world inspections. SRIZFLY’s simulator helps pilots practice safely, identify risks, and respond to emergencies, greatly reducing the likelihood of crashes or errors during field operations. With over 10 years of experience in drone powerline inspection simulation, SRIZFLY brings extensive expertise in real-world UAV inspection operations.
Zero-risk training before entering high-voltage fields
Simulation provides a safe, controlled setting to practice powerline inspection maneuvers before operating near energized towers. Trainees learn to handle high-voltage environments, tower structures, narrow work corridors, and approach paths without real-world danger. The system reinforces safe-distance awareness, clearance judgment, and obstacle avoidance around conductors, cross-arms, and guy wires. By the time pilots enter live sites, they already understand utility flight discipline and safety procedures, reducing accidents and protecting both equipment and grid assets.
Accelerated learning and shorter training cycles
Simulation allows pilots to repeatedly practice standard inspection missions in diverse environments, from plains to complex mountainous powerlines.Trainees can complete more training cycles in less time, mastering critical maneuvers faster than field-only training.
Data-driven and measurable performance evaluation
Simulation tracks every inspection photo and evaluates its quality against predefined standards, including clarity, angle, and coverage of critical points.Trainees receive measurable feedback on each photo, enabling objective assessment of inspection accuracy and overall work quality.This data-driven evaluation ensures pilots meet operational standards before real-world deployment, improving reliability and reducing errors in field inspections.
Design and Standards of Power Line Inspection Drone Simulation Systems
Design and Development of Powerline Inspection Drone Simulation Systems Must Follow Official Industry Standards.
Our simulation system strictly follows authoritative Chinese regulations:
- DL/T 1482-2015 《架空输电线路无人机巡检作业技术导则/Technical Guidelines for UAV Inspection of Overhead Transmission Lines》
- T/CEC 193-2018 《电力行业无人机巡检作业人员培训考核规范/Training and Assessment Standards for UAV Inspection Personnel in the Power Industry》
- 《无人机数字航空摄影测量与遥感外业技术规范/Technical Specifications for UAV Digital Aerial Photogrammetry and Remote Sensing Fieldwork》
- 《民用无人机驾驶员合格评定规则/Civil UAV Pilot Qualification Assessment Rules》
These standards define flight procedures, inspection workflows, point positioning, risk control, training, and assessment, providing the top-level framework for industry operations and personnel development.
Chinese standards are chosen because they cover the longest, most complex transmission networks, full operational scenarios (marine, desert, mountains, extreme cold, typhoon zones), and strictest safety and qualification requirements.
Our system is built according to these standards to ensure that training results directly translate into real-world inspection capability.
