中文摘要:在分析风力机制动数学模型的基础上,设计了柔性制动系统,搭建了半物理混合仿真实验台,并在实验台上进行了风力机柔性制动模拟仿真实验。实验结果表明,风力机正常停机时,柔性制动系统通过改变PLC的PWM输出控制高速开关阀通断时间,从而调节制动力,完成柔性制动过程,可以使叶轮转速下降平缓,风力机齿轮箱扭矩波动减小。

Abstract:A soft braking system was designed based on the mathematic model of wind turbine braking, and a semi-physical simulation test-bed for wind turbine was really formed. Analog simulation experiment for wind turbine soft braking was performed on the test-bed. Experiment results indicated that, when the wind turbine was regularly stopped, soft braking controls the high-speed switch valve on-off time by means of varying the PWM output of PLC, to adjust brake force through, which can make rotor speed fall down gently and minish the gearbox torque wave. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
