Voltage Profile Improvement of Transmission Lines Using Static VAR Compensator

Devendra Kumar Sahu, Ankit Dubey

In the present scenario the power system are operated nearer to their stability limits due to economic and environmental reasons. Now days a stable and secure operation of a power system is therefore a very important and challenging issue. Efficient transmission of voltage and stable operation of the power system is very much essential. The stability has been given much attention by power system researchers and planners in recent years, and is being regarded as one of the major sources of power system problems and insecurity. To compensate these problems in transmission system svc is used. A static VAR compensator is chosen as a low cost solution to replace a conventional capacitor bank, thus allowing a continuous and flexible nodal voltage adjustment. Due to simplest structure, easy designing and low cost, PI controller is used in SVC as voltage regulator is used to regulate the voltage in most industries. In this paper shunt FACTS device-SVC is used in transmission line for improving the voltage profile and stability. MATLAB Simulink platform has been used in this study.
