Feedback Control of Transmission Line by Static VAR Compensators (TSC {&} TCR) Using Fuzzy Logic.

Voltage profile maintenance of a transmission system can be done by using feedback control methodology and the compensation technique used is Static VAR compensation. This thesis describes a MATLAB based SIMULINK model that can be implemented in real time systems to maintain a constant voltage profile during load changes and fault conditions. In any power system the basic requirement is to keep the voltage of the system constant so that the load functions properly. Whenever there is a fault or any load is disconnected, the active and reactive power requirements of the system changes. As a result, the voltage of the system changes. Therefore to maintain a constant voltage profile shunt compensators are used near the load end, in the model presented in this project. Fuzzy logic is also implemented to set the proper compensation required.
