| Wind power as a clean energy in the case of the increasingly tense energy crisisemerged. In order to reduce the cost of wind power, and conducive to the maintenance,fully hydraulic wind power system to improve this point have important sense, because ofstability for wind power, it is necessary to study the hydraulic system of control. Theimprovement of the hydraulic system will accelerate the development rate of the windpower industry, and will set up a new era of wind power industry.Firstly, this paper describes the status of wind power at home and abroad, and theworldwide research situation of wind power, and proposes generation technology can beimproved and the great advantages of wind power in China.Secondly, the paper researches on the wind power technology and analysis of theproblems under the current technology, has designed the entire hydraulic system based ondeveloped technology of wind power.Once again, design of wind power generation system, found that the instability of thewind power hydraulic system. To solve this problem, based on the physical models of thecomponents, using the AMESim software to analyze the mathematical model, set thecomponents AMESim model and establish the overall system simulation model.Finally, the system model, simulate the stability of wind turbine hydraulic system,analyze the link affecting the stability, and accomplish the stability of the output motorspeed of the entire hydraulic system in order to achieve the stability of the output of thepower generation, through the good control on the key link. The research make analysisquick and easy. Comparing the simulation results with experimental results verify thefeasibility of simulation ,the use of PID control technology,and obtained factors affectingthe stability of the system and the solution, the research provides a theoretical basis for thefurther study. |
