coordination of protective schemes in distribution and subtransmission systems including distributed generation
نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
Control of Inverter-Interfaced Distributed Generation Units for Voltage and Current Harmonics Compensation in Grid-Connected Microgrids
In this paper, a new approach is proposed for voltage and current harmonics compensation in grid-connected microgrids (MGs). If sensitive loads are connected to the point of common coupling (PCC), compensation is carried out in order to reduce PCC voltage harmonics. In absence of sensitive loads at PCC, current harmonics compensation scenario is selected in order to avoid excessive injection of...
متن کاملIntegration and Operation Strategies for Inverter-interfaced Distributed Generation System
This paper describes an inverter-interfaced distributed generation system that is interconnected with the electric power system. This system has two main goals: to serve customers with reliable electric power and to improve power quality. This system is interfaced through inverters because they are effective to control output voltage and current. Because DGs are interconnected with the electric...
متن کاملTransient Stability Enhancement in Microgrids Including Inverter Interfaced Distributed Generations
With increasing the presence of Microgrids (MGs) in the power systems, investigating the MG stability during transient faults is necessary. This study investigates the transient stability analysis of a MG supplied by multiple inverter interfaced distributed generations (IIDGs) during fault. The transient stability of a MG is highly depends on the IIDGs control strategy. A MG, simulated on Matla...
متن کاملNeural Network Controller for Harmonic Elimination in Multilevel Inverter
Uninterruptible power supplies (UPSs) are emergency power sources which have wide spread application in critical equipments, such as computers, automated process controllers, and hospital instruments. With the rapid growth in the use of high-efficiency power converters, more and more electrical loads are nonlinear and generate harmonics. It is a big challenge for a UPS to maintain a high-qualit...
