The inherent time-varying nature of the wind farm power causes undesired voltage flicker in network. In order to mitigate enhance performance system with very fast dynamics, static VAr compensator (SVC) is utilized. However, SVC operates some delays which negatively affects its performance. This persuades us predict reactive compensate for real-world delay. predicted then utilized SVC. Therefor...

From February to May 1997, three devastating earthquakes occurred in rural areas of north and east of Iran. Considering the three consequent earthquakes in bad weather conditions and remoteness of the affected areas, the overall performance of the rescue and relief operations was excellent. In all these earthquakes 95 per cent of people were rescued within first 24 hours and by 48 hours all the...

In this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for V47/660kW wind turbine operated in Manjil wind farm, Gilan province, Iran. According to the acquired data from Iran wind turbine industry, common faults of the wind turbine such as sensor fault...

One of the major challenges in grid-connected wind farms is flicker emission caused by reactive power extremely short time variations. A general used solution installing a static volt-ampere (VAR) compensator (SVC) as most cost-saving device, which still holds risk incomplete compensation subject to operating delay time. To this end, an accurate extreme short-term forecasting structure essentia...

abstract temperature is the most important environmental factor that affects flowering and fruiting. the temperatures induce reproduction and cause damaging to tree or its crop.this paper analyzed daily minimum temperatures 0.0oc, and maximum temperatures 12.5 oc from october 1 to may 31 at nine sites in olive producing and cultivating regions, and one control station, using thermal adaptabilit...

in order to study of genetic diversity and similarity among four native olive cultivars including ‘mari’, ‘zard’, ‘shengeh’ and ‘rowghani’, these cultivars were evaluated in five regions including ali abad, gilvan, tarom, manjil and jamal abad at 2012-2013. there was a significant difference among studied individuals. the correlation coefficient analysis among studied traits showed that there w...
