Abstract: To study the dynamic characteristics of large-scale wind power integration is important significance for the improvement of power system stability. This paper analyzed the working principle of wind turbine generation unit, hydraulic turbine generation unit and steam turbine generation unit respectively, and established the corresponding mathematical model. On the basis of the above, this paper constructed the model of multisource hybrid electric power system including wind turbine generation unit, hydraulic turbine generation unit and steam turbine generation unit, and analyzed the model under the conditions of wind speed fluctuation. The simulation results show that when the output power of the wind turbine is changed, the multisource hybrid power system model can accurately describe the dynamic characteristics of various parameters of the power system.
Key words: wind turbine generation unit; hydraulic turbine generation unit; steam turbine generation unit; large-scale wind power integration;
multisource mixture electrical power system
