The Research And Development Of Simulation Test Platform For Wind Trubine Generator System

The establishment of the wind turbine simulation platform, similar to the real operating environment, operational status, I/O interfaces and control system, has an important and realistic significance. At the same time, the rapid development of computer interface technology, automatic control theory and digital simulation technology provides the conditions for the realization of the simulation platform.In this paper, built a wind power system model, as the basis for the establishment of all-digital simulation platform for wind turbine generator and digital + physical synthesis simulation platform.First of all, established a accurate model of wind power generator systems, including wind speed, wind machines, generators, transmission system, yawing system and control system models. Established a dynamic model of wind turbine temperature system for the first time. Modeled the regulating mechanism by adjusting the pitch of blade and yawing system with first-order model. Using BP network to model the Cp curve of wind turbine.Second, introduced the all-digital simulation platform, and sub-section described its objectives, significance, function, structure, function realization, operating methods and so on. Completed friendly man-machine interface and full-featured application with Visual C++ 6.0.Once again, introduced an integrated digital + physical simulation platform including the meaning of the platform, function, composition, function realization and operating methods etc. Detailed described the hardware I/O interface including the composition and performance indicators, and gave a brief description of the remaining physical part.Finally, forcasted and estimated the work that should be done in future for improving the application and the Ct curve.
