Research on data processing for condition monitoring of wind turbine based on Hadoop platform

摘要

The status monitoring data of wind turbines have large, multi-source, heterogeneous, complex and rapid growth of large data characteristics. The existing data processing methods are difficult to guarantee efficiency when handling massive amounts of data, and may miss the best time to troubleshoot. How to deal with the monitoring data more efficiently is of great significance to the accurate judgment of the fault. This paper proposes the use of cloud platform to deal with massive data to improve efficiency. Firstly, the state monitoring model of wind turbine is put forward. Then, the fuzzy C means clustering algorithm is introduced, and the algorithm process is realized by MapReduce model. Finally, the experiment is carried out with Hadoop platform, using distributed database HBase to store data, and using distributed programming framework MapReduce to calculate data. It is found that with the increase of the data volume and the number of nodes, the cloud platform is able to store and calculate data at a faster speed.
