CSC Use for Power Flow Control in the Electrical Power System- A Review

Electrical & Electronics

Today’s power system demand have been increase with loads, it is more difficult to provide stability and control. Power electronic controllers for a flexible ac transmission system (FACTS) can offer a greater control of power flow, secure loading of power system. In this paper deals with possibilities of the thyristor controlled series capacitor (TCSC) to control power flows in interconnected power systems. The main goal is to describe the working principle of TCSC and its possible use in the transmission system and advantages and disadvantages of using of such equipment in the electric power system. FACTS technology new opportunities for controlling power and enhancing the usable capacity of present, as well as new and upgraded lines. A TCSC is a one of series FACTS device. The real and reactive power flow in the transmission line can be controlled by changing the magnitude and phase angle of the injected voltage produced by the series converter. In this paper discusses that used a TCSC to improving the real and reactive power flow of the power systems.
