Transient Performance Of A Series Compensated Transmission System

There are many different methods used to improve the stability of power systems. One of them is series compensation; it is the use of capacitance in series with the transmission lines. The addition of capacitance serves multiple purposes the most important being the improvement in the stability along the entire line and they are also found on long transmission lines used to improve voltage regulation. The series capacitors are provided with modern capacitor protection techniques Metal Oxide Varistors (MOV) to protect from high voltages that would be seen across their terminals when there is a faulty condition (very high currents). Transient tests are to be performed on the model of power system for desired load flow and to obtain a steady state. For some faults, the transient performance of the system is analyzed. One of the major and hazardous disadvantage of series compensation is Sub-synchronous Resonance is considered and analyzed for various degrees of compensation. In our project, we have built the simulations of the above mentioned systems and their transient performances are thoroughly analyzed and developed using MATLAB 7.0.1 and also using SIMULINK. The reason for choosing MATLAB is, it is a high-performance language for technical computing
