摘要: 针对大容量风电系统风轮的大惯量特性所造成的系统在快速响应控制上的困难,基于风力机特性和永磁同步电机数学模型,建立风电系统的仿射性非线性模型,运用微分几何学原理及反馈线性化理论提出系统转速控制策略。在此基础上引入负载转矩前馈补偿的方法,形成一种易于物理实现的快速响应控制策略。具有较高相较于传统矢量控制策略及电压前馈解耦控制策略,所提控制策略在大容量风电机组快速响应控制问题上具有较高有效性和先进性。

Abstract: Because of large system inertia in high capacity wind power turbines, it is difficult to respond quickly to controls. Based on wind turbine characteristics and PMSM mathematical model, a non-linear affine model is established for wind power system. A system speed control strategy is proposed by using differential geometry principle and feedback linearization theory. A load torque forward compensation method is introduced to form a rapid response control strategy with easy physical implementation. Compared with traditional vector control stagey and voltage decoupled forward compensation strategy, the simulation results show the effectiveness of proposed method in large capacity wind turbine quick control response.

Key words: large scale direct drive wind turbine, feedback linearization, MPPT, large inertia load, torque feedforward
