چکیده
One of the indicators of safe operation in the power system the dynamic stability of the power system against disturbances such as short-circuit, off and switch transmission lines, load variation and production is ,Which is the ability and capability to return the power system to steady state and maintain synchronization against such disturbances .Since disturbance in an electrical grid is unavoidable,so the improvement of dynamic stability in different directions is of particular importance, Which include Reducing the number of unwanted outputs, Rise of equipment life span, Optimal utilization of available capacities in power plants, Improve the quality of electricity. Due to the fundamental changes in the network topology and so the deviation of the model parameters of some components of the power plant, such as generator and turbine, relativ to the Installation time, it is clear that The controller settings of these units are out of optimum mode.This matter has also been a local influence on the the stability of the power plant. And more generally, can affect the overall network stability Additionally, these controllers may not be optimized at the installation time and commissioning of the power plant. Also, in many PSS power plants, this controller is out of range due to inappropriate settings. One of the most important tools required to carry out these activities is to have a precise dynamic model of the network, in particular the components of the energy generation units, including generator, excitation system, PSS, governor and turbine. Currently, for the modeling of Iran s network, considering the lack of precise models, examples of standards, articles, or Producer companies are used, that they may differ from the existing reality. This can lead to unusual conservatism in the studies and exploitation of the power system and or it can cause unwanted problems Therefore, it is important do identification tests to determine the exact model of the components of the power plants and to have a consistent and regular program Periodically for these experiments In this paper, a method is based on simulating by Particle Swarm Optimization algorithm (PSO) Which is discussed for tuning in the power stabilizer system (PSS).کلیدواژه ها
