Dağıtık üretim, yeni bir uygulama alanıdır ve uygulama yaygınlaştıkça yeni sorunlarla karşılaşılacaktır. Çıkabilecek sorunlara aday konulardan biri, mevcut röle koordinasyonunun bozulması ihtimalidir. Herhangi bir arıza olmasa dahi, devre kesiciler tetiklenebilir veya bir arıza durumunda tetiklenmesi gereken kesiciler devreyi kesmeyebilir. Ayrıca,...

Over the last decades, solar energy systems have aroused much interest due to increased concern for the environment. Photovoltaic (PV) module based electric power generation systems present promising solutions to ensure sustainable, abundant, inexhaustible, and environmentally friendly energy. In view of the foregoing, converters used in PV systems...

This paper proposes to estimate the electrical characteristics and maximum power point of a photovoltaic (PV) panel under variable environmental conditions in fianlfiurfa region (southeast of Turkey). Variable environment conditions cause to change of current, voltage and maximum power point (MPP) of PV panels. Under any environmental conditions th...

Pansy (Viola cornuta) is a facultative long-day plant that flowers from October until March in Turkey. During the winter months, low light levels can limit plant growth and development. Light emitting diodes (LEDs) can provide supplemental lighting in greenhouses which produce same light intensity with less energy than conventional incandescent lig...

Electric power quality (PQ) in distribution system has become increasingly significant subject both for end users and power suppliers with the deregulation of the electric power market. The inadequate performance of conventional compensation devices to mitigate PQ problems has revealed the use of advanced power electronics based compensation device...

Power quality (PQ) problems have become a serious concern of both power suppliers and end user customers with the deregulation of the electric power market. In the recent years, power electronics based compensation devices with advanced technology has been required due to the inadequate of conventional compensation devices to improve PQ in utility...

Abstract Plants need light for a good development. During the growth of plants, the required sources of the light are provided by either the sun or artificial lights. Recently, lighting which is cheaper and more intense activity in the plant photosynthetic light quality can be achieved with LED (Light Emitting Diode-Light-Emitting Diodes) technolog...

The use of split-type air conditioners (STAC) is very popular in residential and commercial buildings and demand for these types of air conditioners is increasing year by year. Theoretical and practical case studies for fault detection and diagnosis of STAG constitute a vital part in technical services and refrigeration/air-conditioning laboratorie...
