摘要
受参数与工况差异影响,风电场多机组间响应特性存在差异,难以同时完成功率参考值给定,降低了控制系统的稳态精度和动态特性。对于风电场控制系统中的灰色不明确部分,以灰色理论为基础,以风电场闭环最优动态响应为目标,加入灰色PID控制算法,创建变桨风电机组的灰色模型,并施以预测补偿。仿真实验及研究表明,使用灰色PID控制能准确跟踪功率变化,响应快,误差小,明显提高系统性能和控制效果。
As for the wind farm control system＇s gray part is not clear,in order to get the optimal dynamic response of the wind farm,based on grey theory,this paper constructs a grey model of variable-pitch wind turbine which adds grey PID control algorithm to impose predictive compensation.Experiments and simulation studies have shown that using gray PID control have fast response and small errors,which can also accurately track the changes in power.
