基于风场AGC调度控制的三区域控制法

Three-area Control Based on AGC Dispatch Control in the Wind Farm

针对电网调度中心对风场的自动功率调度目标要求,在分析MW级双馈变桨风机机组运行特性的基础上,采用传统的PID控制为基础、结合控制保护区域检测单元、机组控制输出保护单元组合的三区域控制系统建立的风场有功控制单元,针对莱州风电场进行AGC控制测试,证明三区域控制系统具有良好的系统控制性能。

With respect to the automatic power dispatch target set by the grid dispatch center on the wind farm, based on the analysis of the oPerational characteristics of the double-fed pitch-controlled MW wind turbine, the wind farm active control unit adopting the 3-area control system { traditional PID control in combination with the control/protection area test unit and the control output protection unit） is tested on its AGC in the Laizhou Wind Farm, and the result proves that the 3-area control system has a good system control function.
