【摘要】：为了提高风力发电机的发电功率和使用效率,需要进行风电发电功率有效预测,实现电机优化控制。提出一种基于模糊PID的风电发电功率预测模型。首先建立风电发电机的电路模型,以风电发电机的输出目标电流、输出功率、励磁电流和动子电流等参量为约束参量模型,进行风电发电机的控制器模型设计。在优化控制模型中,根据基尔霍夫电压回路模型建立发电功率预测的模糊PID控制目标函数,并进行最优解求取,实现发电功率有效预测。实验结果表明,采用该方法进行风电发电功率预测的精度较高,收敛性较好,有效提高了风电发电机的输出效率。
[Abstract]:In order to improve the generation power and efficiency of wind turbine, it is necessary to effectively predict the power of wind power generation and realize the optimal control of the generator. A fuzzy pid based power prediction model for wind power generation is proposed. Firstly, the circuit model of wind generator is established. The output parameters such as target current, output power, excitation current and mover current are taken as the constrained parameter model to design the controller model of wind generator. In the optimal control model, the fuzzy-PID control objective function of generating power prediction is established according to Kirchhoff voltage loop model, and the optimal solution is obtained to realize the effective generation power prediction. The experimental results show that the proposed method has high accuracy and good convergence, and can effectively improve the output efficiency of wind power generators.
