The invention relates to a transformer station three-dimensional real scene simulation system and an implementation method. The system comprises a safety region monitoring unit, a three-dimensional visualization display unit, and a system management unit. The safety region monitoring unit comprises a wireless real-time positioning module using a UWB positioning technology, a moving target security monitoring module, a moving target information query module, a target historical data query module, a safety region early warning setting module, an equipment information query module, and an alarm management module. The three-dimensional visualization display unit comprises a roaming module, an operation deduction module, a field operation instruction scheme making module, and a risk management and control module of an electrified dangerous region. The system management unit comprises a user management module, a system setting module, and a log query module. The system realizes functions of daily inspection and maintenance visual management of a transformer station, operating personnel daily inspection and maintenance process real-time tracking and monitoring, security alert alarm and intelligent recording management.
