摘要
以捕获最大风力发电机组功率为目的,提出了变增益分段组合控制策略。该控制策略通过分析变速恒频风电机组主要采用的两种变速变距控制方法,根据功率-转速曲线,提出了变增益式分段组合控制策略,将变速恒频风电机组发电运行分成3个区域:低于切入风速,高于切入风速低于额定风速和高于额定风速,针对每个区域分别采用不同的变增益组合控制方法和实现方式;并通过Bladed软件仿真验证了组合控制策略的可行性,在不同运行区域控制结果能够满足控制策略的要求。
To capture the maximum wind turbine power, variable gain regional combination control strategy is pro-posed. The control strategy analyzes two main control strat-egies of variable speed and pitch control applied on variable speed constant frequency （VSCF） wind turbine, and pro- posed variable gain regional combination control strategy ac- cording to the curve of the power-speed. The VSCF wind turbine generating operation is divided into three regions： below cut-in speed, higher than cut-in speed but below rated speed and higher than rated speed. For different operating regions, different variable gain control strategies and imple- mentation are proposed, Finally, a simulation is conducted in the professional software Bladed on the proposed control strategies and results of different regions meet the requirement of the control strategy.
