Power Upgrading of Transmission Line by Combining AC–DC Transmission
Long extra high voltage (EHV) ac lines cannot be loaded to their thermal limits in order to keep sufficient margin against transient instability. With the scheme proposed in this project, it is possible to load these lines very close to their thermal limits. The conductors are allowed to carry usual ac along with dc superimposed on it. The added dc power flow does not cause any transient instab...
متن کاملPower Upgrading of Transmission Line by Injecting DC Power in to AC Line with the help of ZIG-ZAG Transformer
We never loaded a long extra high voltage to their thermal limits in order to keep sufficient margin against transient instability. With this scheme proposed in this paper, it is possible to load these lines very near to their thermal limits. Here we inject dc power in to dc transmission line to carry usual ac along with dc superimposed on it. The added power flow does not cause any transient i...
متن کاملanalysis of power in the network society
اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولDesigning Power Line Filters for DC-DC Converters
A method for designing power line filters for SMPS is presented. The practical design work is optimized, by excluding the nonviable combinations of filter components. The designer can choose among the theoretically viable combinations, to try practical designs. The theoretical calculations are based on chain parameters. As an illustration of the method a single stage π-filter for a buck convert...
متن کاملPower System Stability Enhancement by Simultaneous AC-DC Power Transmission
This paper presents the concept of simultaneous ac-dc power transmission. Long extra high voltage (EHV) ac lines cannot be loaded to their thermal limits due to this instability occurs in the power system. It is difficult to load long extra high voltage (EHV) ac lines to their thermal limits as a sufficient margin is kept against transient instability. With the model proposed in this thesis, it...
