Now daily's electrical power necessity has expanded exponentially while the development and rebuilding of the electrical power framework for age and transmission in the power segment has been basically restricted because of present assets and natural conditions. Accordingly, roughly of the halls of power transmission overhead lines are intensely stacked and clogged. Additionally the serious issue of power framework voltage dependability turns into a power move constraining and capacity factor. A Modern power electronics innovation FATCS based gadget Static Synchronous Series Compensator (SSSC) is a VSC based series FACTS gadget. Bound together power flow controller (UPFC) is to control power flow, voltage magnitude, and phase point. In this examination paper proposed to keep up the voltage magnitude just as power flow of broken lines. The result of change of the power framework parameters, for example, voltage, phase point, dynamic power, responsive power, and in general power factor with and without SSSC and UPFC have additionally been consolidated. Assessment of power framework security is important in the public arena to create approaches to keep up framework activity when at least one segments come up short. A power framework is "secure" when it can resist the loss of at least one fixings and still continue working without serious issues. The Contingency occasion examination strategy is taken to recognize electrical hub power flow in the flawed transmission lines. The Performance of power framework is checked on IEEE 14-Bus System.
