A method of black-start and island operation for Đăkrơsa hydroelectric power plant using fuzzy logic
Abstract
Black Start is the procedure of restoring power by using generators in the event of a total or partial shutdown of the national electricity transmission system. In this paper, the solution to black start and island operation is proposed for the Dakrosa hydroelectric power plant in Kontum province. Firstly, the mathematical model of Đăkrơsa hydropower plant is developed as the basis for the analysis and design of the solution. Secondly,based on this mathematical model, PID and fuzzy control algorithms are proposed to black start and operate in island mode to supply a specified load. Thirdly, to verify the feasibility and the effectiveness of the proposed algorithms, simulations have been carried out on Matlab-Simulink software. The results have shown better mobilization power and frequency stability in case of using fuzzy logic combined with traditional PID algorithm.
