Abstract: The requirement of electricity is increasing at an alarming rate but the running demand of power is ahead of its supply. More the demand more generation. Due to increase generation, synchronism between different parts of power system has become difficult. In this research paper firstly the behavioral study of synchronous machine with PID controller and discrete filter is carried out of transfer by aid transfer function and In the second step point-by-point method using simulink show the transient behavior of the synchronous machine. The prefault condition, during fault and after fault condition is presented in this paper.
