The application provides a generator
transformer unit protection device performance detection
system and method, relates to the generator
transformer unit protection technical field, and solves the problem of single
monitoring data dimension in traditional technology through multi-dimensional data collection and fusion. The
system collects various state parameters of the generator and the
transformer, can reflect the equipment operation state in all directions, accurately identifies electrical, acoustic, mechanical and thermal abnormalities through modular
feature extraction, extracts key features from the
signal by using
fast Fourier transform and other technologies, generates the transformer
abnormality index and the power generation
abnormality index by establishing a mathematical analysis model, and the comprehensive analysis capability can more accurately evaluate the overall
health condition of the equipment. The performance detection module combines the transformer
abnormality index and the power generation abnormality index, calculates the comprehensive abnormality index, compares the comprehensive abnormality index with the preset threshold value, and the
system can timely identify the potential fault state of the equipment.
