This thesis proposes a method and develops a mathematical model for determining the effects of hydro power plants’ governor settings on the Turkish power system frequency. The Turkish power system suffers from frequency oscillations with 20 30 seconds period. Besides various negative effects on power plants and customers, these frequency oscillations are one of the most important obstacles before the interconnection of the Turkish power system with the UCTE (Union for the Coordination of Transmission of Electricity) network. Taking observations of the system operators and statistical studies as an initial point, the effects of hydro power plants’ governor settings on the Turkish power system frequency are investigated. In order to perform system wide simulations, initially mathematical models for two major hydro power plants and their stability margins are determined. Utilizing this information a representative power system model is developed. After validation studies, the effects of hydro power plants’ governor settings on the Turkish power system frequency are investigated. Further computer simulations are performed to determine possible effects of changing settings and structure of HPP governors to system frequency stability. Finally, further factors that may have negative effects on frequency oscillations are discussed. The results of study are presented throughout the thesis and summarized in the “Conclusion and Future Work” chapter.
