风力发电机组控制单元(WPCU)是每台风机的控制核心，分散布置在机组的塔筒和机舱内。由于风电机组现场运行环境恶劣，对控制系统的可靠性要求非常高，而风电控制系统是专门针对大型风电场的运行需求而设计，应具有极高的环境适应性和抗电磁干扰等能力，其系统结构如下：
风电控制系统的现场控制站包括：塔座主控制器机柜、机舱控制站机柜、变桨距系统、变流器系统、现场触摸屏站、以太网交换机、现场总线通讯网络、UPS电源、紧急停机后备系统等。 风电控制系统的网络结构如图1所示：
1、塔座控制站
塔座控制站即主控制器机柜是风电机组设备控制的核心，主要包括控制器、I/O模件等。 控制器硬件采用32位处理器，系统软件采用强实时性的操作系统，运行机组的各类复杂主控逻辑通过现场总线与机舱控制器机柜、变桨距系统、变流器系统进行实时通讯，以使机组运行在最佳状态。
控制器的组态采用功能丰富、界面友好的组态软件，采用符合IEC61131-3标准的组态方式，包括：功能图(FBD)、指令表(LD)、顺序功能块(SFC)、梯形图、结构化文本等组态方式。
