后備危急安全鏈系統(tǒng)獨(dú)立于計(jì)算機(jī)系統(tǒng)的硬件保護(hù)措施，即使控制系統(tǒng)發(fā)生異常，也不會(huì)影響安全鏈的正常動(dòng)作。安全鏈?zhǔn)菍⒖赡軐?duì)風(fēng)力發(fā)電機(jī)造成致命傷害的超常故障串聯(lián)成一個(gè)回路，當(dāng)安全鏈動(dòng)作后將引起緊急停機(jī)，機(jī)組脫網(wǎng)，從而最大限度地保證機(jī)組的安全。

所有風(fēng)電機(jī)組通過光纖以太網(wǎng)連接至主控室的上位機(jī)操作員站，實(shí)現(xiàn)整個(gè)風(fēng)場(chǎng)的遠(yuǎn)程監(jiān)控，上位機(jī)監(jiān)控軟件應(yīng)具有如下功能：

廈門岳航計(jì)算機(jī)工程有限公司

聯(lián)系人：李素云

企業(yè)QQ：2851195446，2851195466

手機(jī)：18965423501

座機(jī)：0592-5165501

① 系統(tǒng)具有友好的控制界面。在編制監(jiān)控軟件時(shí)，充分考慮到風(fēng)電場(chǎng)運(yùn)行管理的要求，使用漢語(yǔ)菜單，使操作簡(jiǎn)單，盡可能為風(fēng)電場(chǎng)的管理提供方便。

② 系統(tǒng)顯示各臺(tái)機(jī)組的運(yùn)行數(shù)據(jù)，如每臺(tái)機(jī)組的瞬時(shí)發(fā)電功率、累計(jì)發(fā)電量、發(fā)電小時(shí)數(shù)、風(fēng)輪及電機(jī)的轉(zhuǎn)速和風(fēng)速、風(fēng)向等，將下位機(jī)的這些數(shù)據(jù)調(diào)入上位機(jī)，在顯示器上顯示出來，必要時(shí)還可以用曲線或圖表的形式直觀地顯示出來。

③ 系統(tǒng)顯示各風(fēng)電機(jī)組的運(yùn)行狀態(tài)，如開機(jī)、停車、調(diào)向、手/自動(dòng)控制以及大/小發(fā)電機(jī)工作等情況，通過各風(fēng)電機(jī)組的狀態(tài)了解整個(gè)風(fēng)電場(chǎng)的運(yùn)行情況。

④ 系統(tǒng)能夠及時(shí)顯示各機(jī)組運(yùn)行過程中發(fā)生的故障。在顯示故障時(shí)，能顯示出故障的類型及發(fā)生時(shí)間，以便運(yùn)行人員及時(shí)處理及消除故障，保證風(fēng)電機(jī)組的安全和持續(xù)運(yùn)行。

⑤ 系統(tǒng)能夠?qū)︼L(fēng)電機(jī)組實(shí)現(xiàn)集中控制。值班員在集中控制室內(nèi)，只需對(duì)標(biāo)明某種功能的相應(yīng)鍵進(jìn)行操作，就能對(duì)下位機(jī)進(jìn)行改變?cè)O(shè)置狀態(tài)和對(duì)其實(shí)施控制。如開機(jī)、停機(jī)和左右調(diào)向等。但這類操作有一定的權(quán)限，以保證整個(gè)風(fēng)電場(chǎng)的運(yùn)行安全。

⑥ 系統(tǒng)管理。監(jiān)控軟件具有運(yùn)行數(shù)據(jù)的定時(shí)打印和人工即時(shí)打印以及故障自動(dòng)記錄的功能，以便隨時(shí)查看風(fēng)電場(chǎng)運(yùn)行狀況的歷史記錄情況。
