The invention discloses an
offshore wind power fault monitoring method based on a
knowledge graph and digital twinning, and aims to solve the problems that multi-
source data acquisition is dispersed, the
transmission delay is high, and real-time convergence and integration are difficult to realize in the operation state monitoring of
offshore wind power equipment. According to the invention, the following modules are provided: a multi-
source data acquisition layer is used for solving the problems of dispersed
data acquisition and transmission
lag and ensuring the real-time performance; the
knowledge graph construction module is used for solving the problems of extraction, fusion and storage of equipment entity relationships; the digital twin modeling module realizes
visual presentation and accurate
simulation of the state of physical equipment; the fault monitoring reasoning module solves the problems of
anomaly detection and
root cause positioning; the intelligent early warning decision module determines an early warning level and efficiently matches a solution; the
visual interaction module solves the problems of scattered information display and poor linkage, supports third-party docking, realizes accurate early warning and
root cause positioning, improves the decision-making efficiency, adapts to severe environments, supports large-scale
wind power plant monitoring, and reduces the operation and maintenance cost.
