One of the concepts in restructuring the electric power industry is the ability to accurately and rapidly quantify the power transfer so-called as the available transfer capability (ATC). Accurate identification of ATC provides vital information for both planning and operation of the bulk power market in reserving transmission services. There are various methods used to determine ATC such as th...

Abstract In this work, a dynamic optimizer (DO) is enhanced with elements taken from the Modifier Adaptation (MA) methodology for Real-Time Optimization (RTO). The objective to use capability of MA methodologies reach real optimum process despite existence process-model mismatch. modifiers are computed during transient, without waiting several steady states occur, speeding up time required plan...

background: transient and stable transformation of host plants are the common techniques to produce transgenic plants. however, the main drawback of stable transformation is the fact that it takes quite a long time to produce a transgenic line. while, transient gene expression is a quick method to produce recombinant proteins in plants.  objective: the main goal of the present study was to eval...

Abstract: At present, the common practice in the power system of China is to represent the small and medium hydropower generator group as a negative load. This paper presents a method to build a dynamic equivalent model of the hydropower generator group using a 3rd order generator model and a static characteristic load model. Based on phasor measurements in the tie line which connects to the mo...

There are typically uncertain parameters in power system models. This paper presents a computational method for evaluating the effect of parameter uncertainty on the dynamic behaviors of power systems. The effect of parameter uncertainty is represented by system trajectory or performance bounds around ccepted 23 April 2008 vailable online 5 June 2008 eywords: arameter uncertainty uccessive line...

Among the many force s to which hydraulic structures are exposed to, the forces induced by cavitation incident are of typical hydrodynamic unknown forces. The aim of this study is to define these forces as coupled fluid-structure interaction under two dynamic effects. The first dynamic effect which incorporates facilities for dealing with cavitation fluid is based on the appearance and bursting...

Aiming at the impact process of a fuel tank, which is transient energy conversion process, material absorbs through deformation to analyze mechanical properties tank during process. The defense node method adopted simulate dynamic response impact. results show that it can accurately evaluate safety container.

The paper presents a deterministic method of estimating the transient inductance and rotor resistance of an induction machine for field commissioning purposes. The parameter values obtained by the method are compared with those for a transient method of commissioning. Skin effects inherent with the transient test are documented. Experimental results for a wide range of machine sizes are include...

Instantaneous friction and wear energy density are important indicators of the state tooth flank milling cutter. Existing methods for identifying on cutters mainly focus overall level consumption maximum width accumulated teeth flanks, ignoring unevenness variability volume distribution tool flank, dynamic relationship between instantaneous each cutter is to be revealed. Transient cutting posit...
