Study On The Datong Area Power Grid "Black-start" Scheduling Plan And Full Process Simulation

This paper studies the Datong area power system black start scheduling plan "". According to the actual situation of the grid is the one’s own knack in Datong area selection of small thermal power as the black start power supply, and the implementation of the black start scheme are studied in detail. At the same time, the Datong area power grid "black start" in the process should pay attention to the problem, such as over voltage, self excitation, gradually restore the system load and other aspects are analyzed. This paper lays the foundation for the specific implementation in Datong area power grid "black start".This text probe into electric wire netting " black-start " the concept and specification requirement at first. " black-start", should guarantee that there is reliable starting power at first. Secondly confirm that " black-start " route according to the structure characteristic of the system. In addition study in " black to start " question and corresponding countermeasure that might appear among the course.Through analyse and research a large number of throughgoing and painstaking investigations of generating sets of electric wire netting of Da Tong, and possess since the aircrew which starts ability carries on feasibility to compare, when all black that the electric wire netting of Da Tong happens we, the power plants had jurisdiction over choose 3#’4# machine of power plant of Guangling as the black starting power that started in case of losing the factory and use electricity. The power plant of Guangling has been since starting successfully, according to starting and keep the short aircrew’s principle of power plant of hot time of the boiler as soon as possible, hands over the factory and uses the electricity to the first power plant in Da Tong immediately. According to the electric wire netting structure of Da Tong, confirm that" black-start" route. This text through a large number of theory computational analysis, after proving aircrew, power plant of Guangling start, charge and to Da Tong one bus bar,110kV of power plant, become typical generator bring unloaded long circuit behind the structure directly, aircrew, power plant of Guangling, can’t take place excitation and 110 kV bus bar of the first power plant in Da Tong can’t take place the issues, such as voltage,etc.In this paper, preparation of Datong district power grid black-start dispatch plan, The whole plan from the "black start" the choice of the power plant unit to the datong area power grid normal operation, Always revolve around the principle of "practical, feasible, practical strong", This plan for Datong area power grid scheduling all black processing power grid accident at all levels has played a guiding role.
