Hessian Locally Linear Embedding of PMU Data for Efficient Fault Detection in Power Systems
نویسندگان
چکیده
This article develops a computationally efficient fault-detection method for power systems, by exploiting phasor measurement unit (PMU) data and Hessian locally linear embedding (HLLE) technique. First, via HLLE technique, high-dimensional PMU are transformed into low-dimensional coordinates, which effectively captures the fluctuations of data. Next, based on feature space T-squared statistic is employed online fault detection. The evaluated IEEE 39-bus system real-world system, exhibiting decent performance as well considerably lower computational complexity when compared with existent methods.

Hessian eigenmaps: locally linear embedding techniques for high-dimensional data.
We describe a method for recovering the underlying parametrization of scattered data (m(i)) lying on a manifold M embedded in high-dimensional Euclidean space. The method, Hessian-based locally linear embedding, derives from a conceptual framework of local isometry in which the manifold M, viewed as a Riemannian submanifold of the ambient Euclidean Space R(n), is locally isometric to an open, c...
متن کاملRobust Hessian Locally Linear Embedding Techniques for High-Dimensional Data
Recently manifold learning has received extensive interest in the community of pattern recognition. Despite their appealing properties, most manifold learning algorithms are not robust in practical applications. In this paper, we address this problem in the context of the Hessian locally linear embedding (HLLE) algorithm and propose a more robust method, called RHLLE, which aims to be robust ag...

متن کاملFace Detection Using Locally Linear Embedding
ii Abstract Human face detection in gray scale images has been researched extensively over the past decade, due to the recent emergence of applications such as security access control, visual surveillance and content-based information retrieval. However, this problem remains challenging because faces are non-rigid objects that have a high degree of variability in size, shape, color and texture....
متن کاملBearing Fault Diagnosis Based on Statistical Locally Linear Embedding
Fault diagnosis is essentially a kind of pattern recognition. The measured signal samples usually distribute on nonlinear low-dimensional manifolds embedded in the high-dimensional signal space, so how to implement feature extraction, dimensionality reduction and improve recognition performance is a crucial task. In this paper a novel machinery fault diagnosis approach based on a statistical lo...
