This paper proposes a dimension root distance and its similarity measure of single-valued neutrosophic sets (SVNSs), and then develops the fault diagnosis method of hydraulic turbine by using the dimension root similarity measure of SVNSs. By the similarity measure between the fault diagnosis patterns and a testing sample with single-valued neutrosophic information and the relation indices, we ...

This research deals with investigations on the “Active Generator” under rotor speed variations and output frequency control. It runs at turbine speed and it is connected to a three phase electrical power grid which has its own frequency different from turbine frequency. In this regard the set composed of a four phase synchronous generator and a natural commutated matrix converter (NCMC) made wi...

The work presented in this paper has two major aspects: (i) investigation of a simple, yet efficient model of the NREL (National Renewable Energy Laboratory) 5-MW reference wind turbine; (ii) nonlinear control system development through a real-time nonlinear receding horizon control methodology with application to wind turbine control dynamics. In this paper, the results of our simple wind turb...

A circuit model is proposed in this paper for calculating the transient potential rise on the wind turbine struck by lightning. The model integrates the blade, sliding contact site, and tower and grounding system of the wind turbine into an equivalent circuit. The lightning current path from the attachment point to the ground can be fully described by the equivalent circuit. The transient poten...

Turbine oil plays an important role in supporting optimal steam turbine performance. Some additives in turbine oil can cause emulsification when the oil is contaminated by water, so demulsibility is a very important property of the steam turbine oil. In order to improve the demulsibility of steam turbine oil, two kinds of polyether-silicone comb copolymers are synthesized and used as steam turb...

Surveys have shown that noise from wind turbines is perceived as annoying by a proportion of residents living in their vicinity, apparently at much lower noise levels than those inducing annoyance due to other environmental sources. The aim of the present study was to derive the exposure-response relationship between wind turbine noise exposure in L(den) and the expected percentage annoyed resi...

The power chimney tower isone of modern promised energy whichmay be developed by low losses,simple and has high facilities.In this paper, many parameters werestudied exactly which influenced theprediction system operation andfundamentally depend on thecombustion gases compound thespilled oil. Velocity distribution is theimportant parameter gives thefirst prediction to put the position oferectio...

This article presents the development of Control-oriented, Reconfigurable, and Acausal Floating Turbine Simulator (CRAFTS). CRAFTS has a modular, hierarchical model architecture that enables rapid accurate simulation wind turbines. The facilitates incorporation variants, its system reconfiguration features help simulate multiple design variants. also supports integration models developed on cau...

This paper examines the city of Steelport in Saints Row: The Third (Volition, 2011) as a real-and-imagined space that can be described using an urban framework of constitutional, representational, and experiential components. It relates mediated and physical cities through spatial arrangement, processes of representation, and the factors that contribute to a sense of place in both material and ...
