This paper proposes a coordinated control algorithm of UPFC and shunt capacitors/reactors. Operating UPFC with this algorithm can keep the voltage of voltage control target buses in the range of desired level and avoid inverter capacity limit problem. In order to maximize operational reserve of shunt inverter, the shunt capacitors/reactors is switched on or off and operating point of UPFC is changed...
The dispatcher training simulator (DTS) provides a realistic environment for system dispatchers to practice operating tasks and experience emergency operation situations. In order to provide a realistic environment, the power system simulator which is a component of the DTS should include models of all devices that exist in real power system such as generating units, transmission devices and loads...
Advanced ring type technology and encapsulating scheme were developed to fabricate highly manufacturable and reliable 256Mb PRAM. Very uniform BEC area was prepared by the advanced ring type technology in which core dielectrics were optimized for cell contact CMP process. In addition, relatively high set resistance was stabilized from encapsulating Ge2Sb2Te5 (GST) stack with blocking layers, thus...
