Research On DSPACE-Based Half-Practicality Simulation For Wind Turbine Intelligent Control

Hardware-in-loop simulation technology with real-time, realistic, research become an effective research tool following the off-line simulation technology in the field of wind power. At present, China's wind power industry, its core technologies, including the main control, viable pitch, converter and so dependent on imports, so our country must master the own intellectual property rights in wind power technique as soon as possible. Therefore, this article focus on wind power technology under the laboratory conditions designed and built a set of wind power in-the-loop simulation platform for development and research in wind power generation technology, and the theory about wind turbine main control is researched and analyzed based on this platform, through the experimental results verify the correctness of theoretical research.First of all, this paper studied the wind speed and wind turbine aerodynamic model, the establishment of a steady wind, gradient wind, gust wind and mixed based on the two-parameter Weibull distribution of wind speed model which is basically accord with the Blade software model and in accordance with the aerodynamics of wind turbine set up a mathematical model. This paper studied four kinds of Wind turbine maximum power pursuit tactic(MPPT) and advantages and disadvantages is comparative too; Beyond the rated speed the constant power control strategy is talked about. This paper introduced the stratification hierarchical control system structure of the wind turbine and analyzed the control theory and research strategy.Secondly, in order to provide a veracious well platform to study the wind power technology under laboratory conditions, this article set up a wind power hardware-in-loop simulation platform with related theories to simulate the 2MW wind turbine. Theoretical studies as experimental validation, this paper has developed a dSPACE-based wind turbine control algorithm process, and test in the simulation platform, the experimental results proves that wind power hardware-in-loop simulation platform is rationality and feasibility, and it is also proves that wind turbine control algorithm process is verify.
