摘要：Small signal stability investigation is vital as the system outage due small signal perturbation being unknown to the system operators. The small signal disturbance may be initiating event for large system outage. The Single Machine Infinite Bus (SMIB) power system helps in tuning the controllers at one machine without considering the effect of other machines in the power system. The effect of disturbance seen by the machine being 100%, whereas in interconnected power system the effect gets distributed among different machines. Therefore, the controller tuning with SMIB remains valid for miltimachine power system as well. In this paper a comparison of PID, PSS, TCDB controllers is presented through small signal stability of power system comprising of one machine connected to infinite bus and modeled through six K-constants. The power system components such as synchronous machine, exciter, power system stabilizer, PID, TCDB are also modeled after linearization of governing equations.
