| Abstract | Unforeseen failures of components of a wind turbine have a significant impact on the power generation capability. Anemometer, which measures the wind speed as seen by the turbine, can be used to predict within some degree of accuracy the amount of power the turbine should produce. It is a good indicator of incipient failures that the power production is consistently low. Unsupervised and automated monitoring of the dynamic behavior of a wind turbine and power produced can detect faults early. Thus, secondary defects and major breakdowns are avoided as well as minimizing the impact this failure has on the total production of the turbine. This paper presents a failure detection method relying on the wind speed differences between two turbines. We collect a week's worth of data and model the wind speed difference between two turbines using a Weibull distribution. Two original tests are proposed. The first test is based on the fitted Weibull distribution, where the abnormal weeks have higher values in both the scale and shape parameters. The second test evaluates the area under the weekly empirical cumulative density function. Both tests yield similar fault detection results, and the second test reveals the sequential progression. A fusion using the second test on multiple turbine pairs can clarify the ambiguity in the single turbine pair test. |

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.
