風(fēng)力發(fā)電機(jī)組控制單元(WPCU)是每臺(tái)風(fēng)機(jī)的控制核心，分散布置在機(jī)組的塔筒和機(jī)艙內(nèi)。由于風(fēng)電機(jī)組現(xiàn)場(chǎng)運(yùn)行環(huán)境惡劣，對(duì)控制系統(tǒng)的可靠性要求非常高，而風(fēng)電控制系統(tǒng)是專(zhuān)門(mén)針對(duì)大型風(fēng)電場(chǎng)的運(yùn)行需求而設(shè)計(jì)，應(yīng)具有極高的環(huán)境適應(yīng)性和抗電磁干擾等能力，其系統(tǒng)結(jié)構(gòu)如下：

風(fēng)電控制系統(tǒng)的現(xiàn)場(chǎng)控制站包括：塔座主控制器機(jī)柜、機(jī)艙控制站機(jī)柜、變槳距系統(tǒng)、變流器系統(tǒng)、現(xiàn)場(chǎng)觸摸屏站、以太網(wǎng)交換機(jī)、現(xiàn)場(chǎng)總線通訊網(wǎng)絡(luò)、UPS電源、緊急停機(jī)后備系統(tǒng)等。 風(fēng)電控制系統(tǒng)的網(wǎng)絡(luò)結(jié)構(gòu)如圖1所示：

1、塔座控制站

塔座控制站即主控制器機(jī)柜是風(fēng)電機(jī)組設(shè)備控制的核心，主要包括控制器、I/O模件等。 控制器硬件采用32位處理器，系統(tǒng)軟件采用強(qiáng)實(shí)時(shí)性的操作系統(tǒng)，運(yùn)行機(jī)組的各類(lèi)復(fù)雜主控邏輯通過(guò)現(xiàn)場(chǎng)總線與機(jī)艙控制器機(jī)柜、變槳距系統(tǒng)、變流器系統(tǒng)進(jìn)行實(shí)時(shí)通訊，以使機(jī)組運(yùn)行在最佳狀態(tài)。

控制器的組態(tài)采用功能豐富、界面友好的組態(tài)軟件，采用符合IEC61131-3標(biāo)準(zhǔn)的組態(tài)方式，包括：功能圖(FBD)、指令表(LD)、順序功能塊(SFC)、梯形圖、結(jié)構(gòu)化文本等組態(tài)方式。
