摘要:

以液压型风力发电机组为研究对象,针对其液压调速系统恒转速输出问题,建立了定量泵-变量马达液压调速系统数学模型,得到了系统泄漏、系统压力瞬态调整和模型参数误差对机组恒转速输出的补偿控制数学模型。以数学模型为基础,给出了液压型风力发电机组恒转速输出补偿控制方法。以30kV·A液压型风力发电机组实验台为仿真和实验基础,对提出的控制方法展开研究。仿真和实验结果表明,液压型风力发电机组恒转速输出补偿控制方法具有较好的控制效果,可实现机组的恒转速输出的高精度控制。

Abstract:

Taking a hydraulic wind turbine as the research object, the mathematical models for fixed displacement pump-variable displacement motor of hydraulic system were established for the constant speed output problem in hydraulic wind turbine. The compensation control mathematical models caused by system leakage, transient adjusting of system pressure and errors of model parameters were derived for the constant speed output. A compensation control method for constant speed output in hydraulic wind turbine was given based on mathematical models. Using 30kV·A hydraulic wind turbine simulation platform as the simulation and experimental platform, the proposed control method was researched. Simulation analysis and experimental results show that the compensation control method for constant speed output in hydraulic wind turbine has good control effect, achieving the high-precision control for constant speed output.

Key words: wind power, hydraulic transmission, constant speed output, compensation control
