摘　　要：建立了风力发电液压储能系统数学模型,分析液压储能发电系统的特点与原理,通过AMESim仿真在该系统带蓄能器与不带蓄能器情况下,对马达转速、转矩、功率进行对比研究。结果表明,蓄能器在新型液压储能风力发电系统中起到辅助动力源、削峰填谷、吸收流体脉动、稳定发电环节的作用。We develop a mathematical model of the hydraulic accumulator for the wind power to analyze the characteristics and principle of the hydraulic energy storage power generation system. Through the AMESim simulation of the system with and without accumulator, the motor speed, torque, power are compared. The results show that the new type hydraulic accumulator energy storage in wind power generation systems plays an important role in assisting power source, load shifting, pulsating fluid absorption and stabilizing the power generation sector.
