The interline power flow controller (IPFC) is a concept of the FACTS controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. This paper proposes a novel IPFC-Based Damping Neuro-control scheme using PSO for damping oscillations in a power system to improve power system stability. The addition of a supplementary controll...
Flexible AC Transmission Systems (FACTS) controllers with its ability to directly control the power flow can offer great opportunities in modern power system, allowing better and safer operation of transmission network. In this paper, in order to find type, size and location of FACTS devices in a power system a Dedicated Improved Particle Swarm Optimization (DIPSO) algorithm is developed for de...
august wilson is undoubtedly one of the rare black playwrights whose works have attracted streams of attention and worldwide audience. the present study aims at analyzing fences and piano lesson which are two of the most successful plays in his pittsburgh cycle from the perspective of michel foucault’s theories and ideas. studying these two plays from foucault’s perspective opens new windows in...
در این مقاله بهبود پایداری ولتاژ بر مبنای شاخص های قابلیت اطمینان سیستم های قدرت از طریق ادوات facts نظیر svc و statcom پرداخته شده است.روش پیشنهادی در این راستا به شکلی است که می توان با کنترل مناسب عناصر جبران ساز شاخص های قابلیت اطمینان را بهبود بخشید. statcom وsvc کنترلر موازی هست و هر یک از این ادوات به طور جداگانه در سیستم قرار داده شده و اثر آن ها بر پارامترهای سیستم ازجمله پروفیل ولتاژ،...
The boiler is one of the most vulnerable parts of a power plant, which is responsible for producing steam for moving turbines. In order to increase the thermal efficiency of the power plant, it is necessary to prevent heat loss in the boiler combustion chamber and simultaneously control the environmental pollutant parameters such as NOx and CO. Failure to control environmental pollutants will...
This paper introduces a new bidirectional, isolated dc–dc converter. A typical application for this converter can be found in the auxiliary power supply of hybrid electric vehicles. A dual half-bridge topology has been developed to implement the required power rating using the minimum number of devices. Unified zero-voltage switching was achieved in either direction of power flow with neither a...
The constant pursuit of higher operating speeds combined with the effort to reduce power consumption creates increasingly stringent requirements for modern I/O interfaces. As the voltage margins shrink and the operating frequencies increase, the quality of the power delivery network becomes the critical factor that determines the I/O performance. A successful I/O design depends on having a robu...
High-power applications of rf often require the use of overmoded waveguide to reduce the probability of rf breakdown by lowering surface fields, as well as to reduce the attenuation due to ohmic losses in transporting the power from the point of generation to the point of use. This is particularly true in the development of warm linear collider designs, such as NLC, JLC, and CLIC, especially th...
