Paper Details

For practical system operation, for the satisfactory operation of the system at a particular operatingcondition, it is important to make sure that the system operates with adequate level of security. Security defines as theability of the system to operate within system constraints (on bus voltage magnitudes, current and power flow over thelines) in the event of outage (contingency) of any component (generator or transmission line). The goal of this powersystem analysis function is to give the information about the static security to operator. Contingency analysis is the studyof outage in the system. Whenever the maximum violation occurs in power system, that line and generator are outageelements. For the generation, transmission, and distribution system, security can be assessed using contingency analysis.For the corrective actions, FACTS devices like TCSC is installed on line by finding proper location by sensitivityanalysis method based on performance index by AC load flow. After installed TCSC device, GSF and LODF sensitivityfactors are calculated and compared for with and without TCSC. This paper presents the modeling of TCSC as anapplication of FACTS devices for the power system security. It also describes the operating modes of TCSC, which one issafer mode, calculation of the TCSC reactance.
