Design And Research On Hydraulic System Of1.5MW Wind Turbine

As energy issues become increasingly prominent, human beings need to seek aclean and easy access to renewable energy. Wind power can not only meet therequirements of human beings for clean energy, and because of the development ofwind power generation technology, the cost of wind power has also been reduced,governments pay more and more attention to the use of wind energy. As the key toolto obtain wind power from the nature, the related technology research of wind powergenerator is very important.Firstly the article summarizes the research status of wind power generator athome and abroad, and discusses the hydraulic system of the current wind powergenerator, put forward the design of the hydraulic system of1.5MW wind powergenerator. By aerodynamics theory knowledge and electro-hydraulic proportionalcontrol technology, the article put forward the design of wind power generatorhydraulic pitch control system,independent hydraulic yaw system and highspeed shaft hydraulic brake system. Through the theoretical calculation,parameters ofthe elements of the hydraulic system are determined,selects the key element model.Used the AMESim software to establish the model of the hydraulic systemof1.5MWwind power generator, and the hydraulic model of independentpitch module, hydraulic yaw module and a high-speed shaft hydraulic brake moduleis simulated in different conditions. The simulation results are analyzed and comparedwith the design requirements, the conclusion is that the system is stable and meet thedesign requirements.
