Controlling of reactive power in transmission line using facts technology with closed loop controller

Abstract

The paper proposes the power flow control in the transmission line using FACTS devices. In the existing system the power flow in the line system is controlled by using STATCOM. In the proposed system we are going to implement the Combined FACTS device. Which is a combination of series and shunt controller like HPFC (Hybrid power flow controller). Comparison of open loop and closed loop are analyzed for fourteen bus system. In the closed loop PI and FOPID are analyzed for both FACTS Devices. The simulation of both open loop and closed loop are done in the Matlab software.
