    摘 要:為了提高風力發(fā)電系統(tǒng)的安全性、穩(wěn)定性和低壓穿越能力,提出了基于滑模自抗擾的風機系統(tǒng)混合儲能控制策略。儲能系統(tǒng)由鋰電池和超級電容構成,并在傳統(tǒng)雙閉環(huán)控制中引入了滑模自抗擾控制器。通過 MATLAB/Simulink 仿真平臺搭建了系統(tǒng)的仿真模型,仿真結果表明,該方法可以提高系統(tǒng)的動態(tài)響應,平抑直流母線電壓波動,提高并網電能質量,且提升了風機的低電壓穿越能力。
    關鍵詞: 風力發(fā)電;低電壓穿越;混合儲能;滑模自抗擾控制

    Abstract: To improve the safety, stability and low voltage ride-through ability of wind power generation system, the hybrid energy storage control strategy of wind turbine system is put forward based on sliding mode auto-disturbance rejection control. The energy storage system is composed of lithium battery and super capacitors, and sliding mode auto-disturbance rejection controller is introduced into the traditional double closed-loop control. The paper builds a simulation model of the energy storage system by MATLAB/Simulink. The simulation results show that this strategy can improve dynamic response of the system, grid-connected power quality, low voltage ride-through ability of wind turbine system and stabilizes DC bus voltage fluctuation.
    Key words: wind power generation; low voltage ride-through; hybrid energy storage; sliding mode auto-disturbance rejection control
