The doubly-fed generators (DFIG) have clear superiority for the applications of large capacity and limited-range speed control case due to the partially rated inverter, lower cost and high reliability. These characteristics enable the doubly-fed wound rotor induction machine to have vast applications in wind-driven generation.In this paper Combined Vector and direct power control (CVDPC) strate...

This paper presents a MATLAB based technology to predict the steady state behaviour of Self Excited Induction Generator. Taking into consideration the fact of rapid growing popularity of Self Excited Induction Generator research has been centered on analysis, control and design of the same for standalone applications. In this paper to obtain relevant performance equations, symmetrical component...

This paper presents a laboratory study on ‘effects of integration of induction generators on grid power quality parameters such as voltage, frequency power factor, harmonics and reactive power’. Study is carried out with different switching sequence of grid connected induction generators. The analysis is done with two squirrel cage induction generators and one wound rotor induction generator co...

In this paper, a co-axial dual-mechanical ports flux-switching permanent magnet (CADMP-FSPM) machine for hybrid electric vehicles (HEVs) is proposed and investigated, which is comprised of two conventional co-axial FSPM machines, namely one high-speed inner rotor machine and one low-speed outer rotor machine and a non-magnetic ring sandwiched in between. Firstly, the topology and operation prin...

The CORBON 2017 Shared Task, organised as part of the Coreference Resolution Beyond OntoNotes workshop at EACL 2017, presented a new challenge for multilingual coreference resolution: we offer a projection-based setting in which one is supposed to build a coreference resolver for a new language exploiting little or even no knowledge of it, with our languages of interest being German and Russian...

Recent results by Ng and Cardie (2002a) challenge the idea–advanced, e.g., by Vieira and Poesio (2000)–that including methods for identifying discourse new descriptions in an anaphoric resolver leads to better results. In previous work we analyzed the literature on discourse-new detection that followed Vieira and Poesio’s original work, and identified a set of features that appear to be present...

Given the relatively small amount of work on event coreference resolution, our understanding of the task is arguably fairly limited. This makes it difficult to determine how to improve an event coreference resolver. We seek to gain a better understanding of the state of the art in event coreference resolution by performing the first publicly available analysis of a Chinese event coreference res...

this work deals with effects of asymmetric stiffness on the dynamic behaviour of the rotor system. the analysis is presented through an extended lagrangian hamiltonian mechanics on the asymmetric rotor system, where symmetries are broken in terms of the rotor stiffness. the complete dynamics of asymmetries of rotor system is investigated with a case study. in this work, a mathematical model is ...
