Association Rules-based Fault Analysis for Electromechanical Systems Used in Thermal Protection of Thermal Power Plants
The conventional fault analysis for electromechanical systems used in thermal protection of thermal power plants directly analyzes the high-dimensional characteristics of fault signals without efficient decoupling and extraction of weak system fault signals,resulting in low fault recognition rate.Therefore an association rules-based fault analysis meth-od is proposed.Efficient decoupling extraction of weak system fault signals is carried out,and based on this,high-dimen-sional feature analysis of fault signals is performed based on association rules.A fault automatic detection process for elec-tromechanical systems used in thermal protection of thermal power plants is designed to achieve automatic system fault detection.The experimental results show that the proposed method achieves improvements in fault recognition rate and fault recognition utility.
