Analysis of gearbox fault diagnosis system of wind turbine based on fuzzy Petri nets

Design and develop a gearbox remote fault diagnosis expert system based on nets considering current situation of operation and maintenance of the gearbox. Suggest a new fuzzy Petri nets parallel deduction algorithm to solve the fuzzy and parallelism of the gearbox fault and the indeterminacy, insufficiency information in the diagnosis process. The simulation and example indicate that this method is accurate and efficient when diagnosing the gearbox faults.
