To Maintain Voltage Stability In Transmission Line Using 2- Level Space Vector Pulse Width Modulation Technique

Abstract

In this paper we have obtained voltage stability in 100 km Transmission Line System. To
achieve this we have used FACTs devices such as UPFC and STATCOM converter, with a
control strategy of 2-Level Space Vector Pulse Vector Modulation Algorithm. By using this
technique it is easy to control the reactive power from sending end to the receiving end of the
transmission system. We have shown here that if the reactive power at receiving end is much
smaller than the sending so the voltage at sending and receiving end is equal to each other.
We have UPFC and STATCOM with linear load system in transmission line system. The
simulation is carried out through POWER SIMULINK in MATLAB.
