IMPROVING DYNAMIC STABILITY OF POWER SYSTEMS BY USING AVR, POWER SYSTEM STABILIZER

This paper introduced a sum method for controlling electrical power systems for multi-machines under dynamic loads by using artificial intelligence. This paper includes complete descriptions of the sum methods used to controlling dynamic power system stability through the method of recognizing pattern and proposition of suitable control systems for re-adjusting the machines in power system for instable cases. PSAT program had been used in analyzing the stability in the power systems. In this paper, the studied power system included dynamic load model, the program gave excellent results in standard time, and the used network consists of 9 bus bars – 4 generators.
