Abstract:Today, one of the important issues of power quality (PQ) in power systems is the current harmonics. Increasing expansion of nonlinear loads at different parts of the electric network makes harmonic distortion flow through the network. This causes the network to have background voltage and current harmonic distortion and even affect on the PQ of linear load performance. Therefore, it is...
Disconnecting microgrid from main grid, may lead to severe frequency changes. Under frequency load shedding method provides a proper protection scheme by shedding certain amount of loads. Under frequency load shedding relay is used for frequency control of islanded microgrid. Each synchronous distributed generator (DG) of microgrid is equipped with a protective islanding detection device such a...
Emotion and cognition are both considered influential factors in language learning. In this study, the role of "emotioncy" (which is a combination of emotion and frequency) in the cognitive load and sentence comprehension of a group of language learners was examined. Emotioncy includes emotions that are evoked by the senses. To this aim, 200 English as a foreign language (EFL) learners were ask...
In this paper, a heuristic mathematical model for optimal decision-making of a Distribution Company (DisCo) is proposed that employs demand response (DR) programs in order to participate in a day-ahead market, taking into account elastic and inelastic load models. The proposed model is an extended responsive load modeling that is based on price elasticity and customers’ incentives in which they...
in this study the performance and emissions characteristics of a heavy-duty, direct injection, compression ignition (ci) engine which is specialized in agriculture, have been investigated experimentally. for this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (bsfc), peak pressure (pp), nitrogen oxides (nox), carbon dioxide (co2), carbon mon...
The safety transfer on the sea is threatened by wind, wave and surge loads. An offshore gangway ensures smooth safe compensating ship’s motion. In a mixed system, huge asymmetric load top of stable platform, displacement its center gravity causes it to exert large dynamic platform. A model under established in this work. Lagrange equation used establish gangway; equivalent method visualize load...
چکیده: مقدمه:از زمانی که پرسلن لامینت ونیرها معرفی شده اند، محبوبیت آن ها افزایش یافته است. آماده سازی دندان با استفاده از این روش، محافظه کارانه بوده و همچنین این رستوریشن ها، زیبا می باشند؛ اگرچه بعضی از مطالعات مشکلاتی را از جمله عدم تطابق مارجین و failure load پایین را برای آن ها گزارش کرده اند. جهت ساخت لامینت تراش دندان باید در مینا باشد و عاج را در برنگیرد. در نتیجه محدودیت هایی درباره ...
