EHV and HV transmission lines are used widely to transfer power from power generating area to large load centers. Nowadays compensating devices which uses modern power electronic devices are mostly used to improve the power transfer capability of transmission line. Use of FACTS devices in transmission line affects protection system very drastically. In this work, we have addressed the issues related with distance protection of transmission line with STATCOM connected at mid-point. To mitigate the
and output power • AC to DC (rectifier) • DC to AC (inverter) • DC to DC (DC-to-DC converter) • AC to AC (AC-to-AC converter) 1.2 AC to DC converter(rectifier) A rectifier is an electrical device that can converts alternating current into direct current. The process is known as rectification. Rectifiers have many uses, but mostly used as components of DC power supplies and high-voltage direct current power transmission system. Because of the alternating nature of the input AC sine wave, the process
theoretical knowledge about the fundamentals of electrical engineering. The course about power transmission really inspired me and forced me to choose my majors in Electrical Power. In my senior years, I developed a strong interest in the field of power generation and power system protection. So, I decided to do my final year project on the “Protection system of 3-phase interconnected distribution system”. I was leading my group in this project and my tasks were the designing and simulation of the
Introduction: The microgrid system comprising of small-scale distributed generation system and loads can be promptly incorporated by means of the renewable energy sources [1-2]. Numerous researches have been conducted on the microgrid notion [3-5]. The performance of microgrid system is complex and irregular while some microsources are associated. In order to understand the behavior of a microgrid with several microsources, key issues such as microgrid control, stability and protection have to be
thanks to the advancement in the field of electronics, most of the manually controlled systems are getting replaced with sophisticated electronic circuits with intelligent controlls. These circuits are capable of monitoring, analyzing and controlling the systems. In earlier days these electronic circuits were fabricated around discrete hardware components such as transistors, logic ICs etc that made the system bulky and costly. Also since the component count was more the failure rate was also more
E90/E92/E93, E46. E36 and E30 then it can be sold with coupe, convertible and saloon body styles. The Hi-Fi Cars During 20th Century of standard series 3 automobiles involve more responsive and powerful engines, enhanced suspension, handling, braking systems, lightweight components, aerodynamic body enhancements and exterior/interior accents. The last M3 model of the Coupe was produced in Germany in 2013 and which can be replaced by F82/F83 M4 convertible and Coupe beginning with 2015 model year. But
relativistic quasi particle, known as Dirac fermions. (Geim et al, 2007) The outstanding electrical conductivity and the transparency and flexibility of graphene-based material have led to research and development of some future technologies, such as flexible and wearable electronics. In addition, graphene can also be used for efficient energy storage materials, polymer composites, and transparent electrodes. (Geim et al, 2007) This paper presents a 2 brief overview on the structure and some properties
