碩士 === 國立臺北科技大學 === 電機工程系所 === 93 === The purpose of this thesis is to study the utilization of gas turbine generator unit as black-start unit, and connect this unit to the bus of power transmission system network outside power plants, for supplying power to auxiliary equipment of conventional fossil-fueled power generating unit during black-start period. This proposed planning is different from Taipower’s existing system with individual black-start unit at each fossil-fueled power plant; such plan not only reduces quantity of black-start units but also saves the initial investment, operation and maintenance costs of black-start unit. In order to search for optimal location of black-start unit, this thesis applies Genetic Algorithm with merit of random searching to plan the optimal energizing path on power system transmission network during black-start period. Once the optimal location of black-start unit is selected, then it will be simulated by power flow analyzing program to review and verify the derived location and energizing path to avoid over-voltage on transmission line, it will be used as the reference in planning of black-start energizing path. The proposed approach of this thesis is applying systems of IEEE 14-bus, IEEE 30-bus and Taipower transmission system network as examined object, and the outcome indicates that searching for the optimal location of black-start units and the energizing path by applying Genetic Algorithm is feasible.
