application of upfc based on svpwm for power quality improvement

در سالهای اخیر،اختلالات کیفیت توان مهمترین موضوع می باشد که محققان زیادی را برای پیدا کردن راه حلی برای حل آن علاقه مند ساخته است.امروزه کیفیت توان در سیستم قدرت برای مراکز صنعتی،تجاری وکاربردهای بیمارستانی مسئله مهمی می باشد.مشکل ولتاژمثل شرایط افت ولتاژواضافه جریان ناشی از اتصال کوتاه مدار یا وقوع خطا در سیستم بیشتر مورد توجه می باشد. برای مطالعه افت ولتاژ واضافه جریان،محققان زیادی کار کرده ...

Early Warning System for forest fires in Mexico

Since 1999, The National Commission for the Knowledge and Use of Biodiversity (CONABIO) contributes to combating Forest Fires in Mexico and Central America, by means of CONABIO ́s program for hot spot detection using remote sensing techniques. Currently the program is using Terra/Aqua-MODIS satellite images between six and eight times a day to detect hot spots which might be considered as possib...

Earthquake Early Warning System Based on Multiple Sensor Network

Earthquake is one of the major natural calamity. So prediction of the reach of earthquake event to the various locations could result in minimizing the disaster due to it. This system contains the design of sensor system and the techniques used for detection and processing of the received signals in real time. In this system, an earthquake which is also known as a tremor or temblor is the resul...
