According to the characteristics and current situation of power transformer fault diagnosis , information fusion technology is introduced into this field of fault diagnosis of power transformer. By studying the general framework of information fusion fault diagnosis process, combined with…

In this paper, a new method of 3D model automatic annotation is proposed based on a two-dimensional Hidden Markov Model(2-D HMM). Growing importance in the last years Hidden Markov Models are a widely used methodology for sequential data modeling. Recent…

AbstractThe frame of an optimization model of coal alloction in a power generation group was introduced in present study. The influence of multi-coals blending and transportation were all considered in the model. Firstly, the impact of each process of coal…

The variable and non-dispatchable output of wind farms brings great difficulty to the quantitative analysis of the economic operation for peak shaving of power system integrated with high penetration of wind power. For the random nature of wind power, the…

With the miniaturization and portability of online detection and grading equipment, traditional PC is being replaced with ARM or DSP embedded systems in beef quality grading industry. As the low basic frequency of embedded system, the traditional beef marbling segmentation…

In this study, the theory of technology analysis and decomposition of the 3-D (three dimensional) visualization of GIS (Geographic Information System) are analyzed, it divides the 3-D visualization of GIS into virtual reality technology, and it presents situation and development…

The rapid development of plug-in electric vehicles (PHEVs) and wind power brings new challenges to power system security and economic operation. Traditional deterministic models fail to capture their extra characteristics. In this paper, PHEVs, wind power and thermal units are…

An integrity monitoring system is an inseparable part of global positioning system (GPS). According to the measurement noise feature of GPS receiver and the degeneracy phenomenon and alleviating the sample impoverishment problem in particle filter (PF). An approach to fault…

Key management play a central role for protecting communication in WSNs. Due to the limited memory resources and energy constraints, complex security algorithms cannot be used in sensor networks. Therefore, to secure data communication and well balance between the security…

The heat exchange station of central heating system has been increasingly widely used as the intermediate hub connecting the heat source and heat users. If the specific temperature control requirements are not satisfied effectively and specifically, the security and stability…
