| Abstract: | A condenser's on-line monitoring and fault diagnosing system has been developed for effectuating fault diagnosis and operational guidance,thus warranting safe and reliable operation of power plant condensers.The fundamental structure,the main functions and the advantages of the system are here being explained.The system employs a diagnosis method,which combines fuzzy neural networks with improved BP algorithm and can swiftly and accurately determine the location of a condenser fault.This fact has been vindicated by on-site practice. |
