Broken damper bars and shorted field winding turns degrade the starting running performance of industrial wound synchronous motors (WFSMs), can lead to a forced outage motor driven process. Testing WFSM rotor windings mainly relies on offline tests, which cannot be performed frequently are known lack reliability. Shorted in detected online from airgap flux measurement, but require sensor instal...

In this paper, we use experimental data collected from an Austin, Texas smart grid test bed with a system-level battery energy storage model to assess the lifetime of batteries in a microgrid operating in islanded mode during a distribution-level outage. We consider a hypothetical microgrid consisting of 21 single-family detached homes and three transformer-level community energy storage (CES) ...

Photovoltaic (PV) systems and other Distributed Energy Resources (DERs) can provide voltage and frequency support to the electric grid through commanded and autonomous operating modes. These functions have been standardized in the International Electrotechnical Commission (IEC) Technical Report 61850-90-7 in 2013; and recently, in response to national and international requirements, are being a...

This paper studies bank loans over the business cycles in Iran to determine the role of Iranian banks in stabilizing credit. By estimating the long-run relations using dynamic OLS and fully modified OLS estimators, the findings show that real bank lending is positively related to real GDP in the long-run providing evidences of the pro-cyclicality of bank lending in Iran. Hence, Iranian banking ...

â â â  â â  abstract: â  china and asean have been maintaining a relationship both cooperative and competitive in the textile trade. due to its labor intensive feature and high dependence on foreign trade , the textile trade has received much attention after the 2008 financial crisis. the customs data (classified by the hs code) from year 2006-2009 is employed to research the impact of the cris...

the purpose of this paper is to evaluate the effect of financial liberalization on exchange rate volatilities of the selected developing countries, which are now known as liberalizing countries. thus we test the hypothesis in which financial liberalization effect exchange rate volatilities in 43 selected developing countries during 1996-2005. accordingly, a regression model of exchange rate vol...

as a result of higher crude oil prices, in one hand, it is expected that alternative energy resources consumption is increased and consumers change their behavior to decline energy intensity too. on the other hand, more alternative energy consumption can leads to a decline of crude oil aggregate demand. therefore, existence of mutual causality between crude oil price and alternative energy cons...

budget plays an important role in public sector management and administration .one of its components is revenues forecasting and without the necessary accuracy in predicting revenues, government deficit will occur and people are incapable of facing with losses of reducing of important and essential services like education and health care. in this study, the rational expectations hypothesis is a...

Pumpable purees from purple-flesh sweetpotatoes (PFSP) were subjected to microwave heating using a 60 kW, 915 MHz continuous flow system, followed by aseptic packaging in flexible containers to obtain a shelf-stable product. Initial test runs were conducted using a 5 kW 915 MHz microwave system to measure dielectric in-line properties and examine the puree temperature profiles. The results demo...
