Abstract |
The low frequency oscillation (LFO) are related to the small signal stability of a power system. The main objective of this paper to achieve damping to low frequency electromechanical oscillation of synchronous generator rotor for stability of system and improve small signal stability. Modern power systems are widely interconnected, highly non-linear and constantly experience changes in generation, transmission and different load conditions. Due to that power system almost all major transmission network in the world are operated nearly close to their stability limit. One of the major factor in power system operation is related to small signal instability caused by insufficient synchronizing and damping torque in the system. It leads generators to pull out from synchronism and sometimes it is also reason for blackout. Small signal stability of synchronous machine under small disturbances is assessed and enhanced for Single Machine connected to an Infinite Bus (Heffron – Philips model). For the given operating conditions, comparative analysis is done with incorporation of power system stabilizer (PSS), PID – PSS for small signal stability enhancement of SMIB system. The system is simulated by using MATLAB / SIMULINK. Comparison is done for specific parameters i.e. Rotor speed deviation and Rotor angle deviation by using two different controller. |
