The comprehensive perception of substation equipment status is the precondition of ensuring safe operation and realizing intelligent patrol inspection of substation. With the development of digital power grid, higher requirements are put forward for the fine management of power equipment. Digital twin technology is one of the ideal ways to realize the real-time perception and evaluation of the running state of equipment by using digital technology such as sensor, Internet of Things, virtual reality and artificial intelligence. Aiming at the problem of precision constraint and error accumulation of physical model, a digital twin modeling method for substation equipment based on multi-parameter perceptual data and a method for equipment operation state evaluation is proposed.
