Abstract :
This paper describes a method to locate and analyses the performance of power system stabilizer (PSS) for damping electromechanical oscillation of power system. It presents a location identification of power system stabilizer based on a participation factor method. The analysis of the load effect on eigen values confirms that the calculation of best location of PSS by participation factor method is more effective in enhancing the small-signal stability of the system. The Recursive Least Square (RLS) algorithm based PID controller is used to tune the parameters of the PSS to achieve quicker settling time for the system parameters such as load angle and speed deviation. The proposed method is applied to the identification location and tuning of PSS in a model of the Indian practical utility system, possessing sixty two buses and 19 machines.
