com Abstract — Development of electrical power supplies began more than one hundred years ago. At the beginning‚ there were only small DC networks within narrow local boundaries‚ which were able to cover the direct needs of industrial plants by means of hydro energy. With an increasing demand on energy and the construction of large generation units‚ typically built at remote locations from the load centres‚ the technology changed from DC to AC. Power to be transmitted‚ voltage levels and transmission

ABSTRACT In this paper we look into the recent trends in power transmission engineering‚ FACTS and HVDC. The first part of our presentation starts with a quick idea of FACTS. FACTS is defined as a power electronic based system and other static equipment that provide control of one or more AC transmission system parameters to enhance controllability and increase the power transfer capability. This paper also deals with the basic concept involved in the usage of FACT controllers which are capable
