چکیده

As the amount of information collected by wind turbines continues to grow, so too does potential its leveraging. The application machine learning techniques as an advanced analytic tool has proven effective in solving tasks whose inherent complexity can outreach expert-based ability. Such is case presented this study, which dataset be leveraged high-dimensional (79 × 7 SCADA channels) and high-frequency (1 Hz). In paper, a series applied retrospective power performance analysis withheld test set containing data collectively representing 2 full days worth operation at Horns Rev I offshore farm. A sequential machine-learning based methodology thoroughly explored, refined, then task identifying instances abnormal behaviour; namely turbine under over-performance. results final suggest that normal behaviour model (NBM), consisting uniquely constructed artificial neural network (ANN) variant trained on abnormality filtered dataset, indeed proves accomplishing objective. Instances over captured developed NBM are discussed, including status uncertainty embedded prediction results.

Performance analysis of modeling framework for wind speed prediction in wind farms

This paper focuses on the analysis of prediction of wind speed in the wind farms. The performance of modeling can be analyzed by using the real time data with different heights of the wind mill. Artificial Neural Network is used here to develop models for predicting wind speed in wind farms. The models are mainly based on back propagation neural network and radial basis function neural network....

Machine Learning Techniques for Face Analysis

In recent years there has been a growing interest in improving all aspects of the interaction between humans and computers with the clear goal of achieving a natural interaction, similar to the way human–human interaction takes place. The most expressive way humans display emotions is through facial expressions. Humans detect and interpret faces and facial expressions in a scene with little or ...
