The invention relates to the field of power
system operation and maintenance, in particular to a three-dimensional
visualization method applied to a substation operation and
maintenance system, which comprises the following steps of: acquiring a three-dimensional model and position information of substation equipment, constructing an integral three-dimensional model of a substation by utilizing technologies such as
laser scanning and
photogrammetry and combining positioning technologies such as GPS (
Global Positioning System) and RTK (Real-Time Kinematic); a sensor is installed on equipment, operation parameters such as
voltage, current, temperature and vibration are collected in real time and transmitted to a three-dimensional
visualization system through a
wireless or
wired communication network, association display of real-
time data and a three-dimensional model is achieved, and the
system provides a three-dimensional view capable of rotating, zooming and translating. The operation state and fault alarm information of the equipment are displayed in real time, and historical
data query and alarm log functions are supported. By analyzing real-time and historical data, the system can identify and predict potential faults of the equipment, generate maintenance plans and optimization suggestions, and support remote
collaboration and
fault handling.
