Under section 431.24 of the DOE's Proposed Rule for compliance with EPCA, the manufacturer would determine the average full-load eeciency of each basic model of electric motor either by testing or by application of an Alternative EEciency Determination Method AEDM. Under section 431.127 of DOE's Proposed Rule for enforcement of EPCA, the DOE would ascertain, through an enforcement sampling plan...

Braking in hoisting drives is used to reduce the speed of the load (cargo) or to stop it completely. Braking can be realized using electrical and mechanical means; mechanical brake is used to hold the suspended cargo after disconnecting the driving motor from the supply. In modern hoisting electric drive systems, in addition to mechanical braking, electric braking is also used. Electric braking...

Performance and economical efficiency of the combined cooling, heating and power (CCHP) system mainly depend on the system structure, operation strategy and choice of facility capacity. This paper proposes a structural configuration of the CCHP system with hybrid chillers, consisting of a combined electric and absorption chiller, whose electric cooling to cool load ratio varies according to dif...

In recent years, environmental and energy problem has become one of the world's hot spot problems. Today, the road cars not only consume a lot of oil resource, but also cause serious pollution to human survival environment. Therefore, to save energy and protect environment, a green environmental friendly electric car instead of fuel car will be needed for sustainable development of the society....

In this paper, the active buckling control of smart functionally graded (FG) plates using piezoelectric sensor/actuator patches is studied. A simply supported FG rectangular plate which is bonded with piezoelectric rectangular patches on the top and/or the bottom surface(s) as actuators/sensors is considered. When a constant electric charge is imposed, the governing differential equations of mo...

electro-thermo-elastic stress analysis of piezoelectric polymeric thick-walled cylinder reinforced by boronnitride nanotubes (bnnts) subjected to electro-thermo-mechanical fields is presented in this article. the electro-thermo-elastic properties of piezoelectric fiber reinforced composite (pefrc) was studied by a modified xy micromechanical model capable of exhibiting full coupling relation be...

A daily peak load forecasting technique that uses artificial neural network presented in this paper. A neural network of used to predict the daily peak load for a period available using one step ahead prediction load to the actual load. The ith index is used as load for the ith day of the year following networks are trained by the back propagation algorithm. from the Nigerian national electric ...

This paper presents a method for applying realtime scheduling techniques to balance the power usage of electric loads in cyber-physical energy systems. The aim of the proposed approach is to achieve predictability of the activation of electric loads to guarantee an upper bound on the peak electric power consumption. The contribution of this paper encompasses several aspects. The relevance of ba...
