| Abstract | A three-level system for condition based maintenance (CBM) of hydroelectric generating unit (HGU) is proposed in this paper. The aim is to overcome the projected problems like monitoring items not covering most critical equipments, information inconsistency or redundancy, and insufficient information exchanging and sharing. A systematic audit to HGU is performed, covering from acquired data and parameters to equipment degradation mechanism and experience knowledge. This is the first step to obtain the unit-relevant information and gauge how reliability-improvement funds can be spent most effectively. The architecture of this CBM system is presented from the low field level to the high enterprise one. Key implementation strategies are described in details, involving hiberarchy storage method for data management, condition monitoring based on equipment criticality and fault modes, combined neural network diagnosis and prediction, and hybrid reasoning techniques based maintenance decision making. Eventually an application in a medium hydropower plant is described. The results show that such a system is feasible and practical, and it's promising to be used in other industrial fields. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
