本發明(ming)屬于大(da)型可變(bian)速抽水(shui)蓄(xu)能機組監控系統協(xie)調控制，具體涉及一(yi)種(zhong)大(da)型可變(bian)速抽水(shui)蓄(xu)能機組監控系統工況協(xie)調控制方法(fa)。

背景技術：

1、可變(bian)速(su)抽水(shui)蓄能(neng)(neng)是(shi)新能(neng)(neng)源(yuan)消(xiao)納(na)的(de)(de)重要設(she)備(bei)，具備(bei)經(jing)濟性高、容量(liang)大、功(gong)率調(diao)節(jie)范(fan)圍寬(kuan)和(he)速(su)度快的(de)(de)特點。在大規(gui)模可再(zai)生能(neng)(neng)源(yuan)接入電(dian)網的(de)(de)背(bei)景下(xia)，可變(bian)速(su)機組(zu)能(neng)(neng)承擔調(diao)峰填谷、調(diao)頻等任務，助力清潔能(neng)(neng)源(yuan)消(xiao)納(na)，維持電(dian)網頻率穩(wen)定(ding)和(he)提高電(dian)網安全水(shui)平。

2、可變(bian)速(su)(su)(su)抽(chou)水(shui)(shui)蓄(xu)(xu)能機(ji)(ji)組(zu)(zu)通常采用(yong)交流勵磁，使得可變(bian)速(su)(su)(su)抽(chou)蓄(xu)(xu)機(ji)(ji)組(zu)(zu)工(gong)(gong)況種類(lei)繁多(duo)，除具有與定速(su)(su)(su)抽(chou)蓄(xu)(xu)機(ji)(ji)組(zu)(zu)相同的(de)(de)靜止、啟動、發電(dian)、抽(chou)水(shui)(shui)、同步調相等工(gong)(gong)況外，還具有發電(dian)空轉、發電(dian)空載、抽(chou)水(shui)(shui)啟動和抽(chou)水(shui)(shui)同期等特有的(de)(de)工(gong)(gong)況。通常機(ji)(ji)組(zu)(zu)還能根據電(dian)網的(de)(de)需要，頻繁、迅速(su)(su)(su)、靈(ling)活地在(zai)不同工(gong)(gong)況間轉換。因此，合理的(de)(de)工(gong)(gong)況協聯控(kong)制是可變(bian)速(su)(su)(su)機(ji)(ji)組(zu)(zu)安全、穩定工(gong)(gong)作的(de)(de)前提。

3、由(you)于可變速抽水蓄能機(ji)組(zu)工(gong)況(kuang)多達十(shi)幾種(zhong)，且轉換關系(xi)多達三十(shi)多種(zhong)，需(xu)要設置專(zhuan)門的機(ji)組(zu)工(gong)況(kuang)轉換模塊(kuai)識別機(ji)組(zu)工(gong)況(kuang)，并(bing)將實時(shi)工(gong)況(kuang)同步發送給勵磁系(xi)統、調速系(xi)統、發電(dian)電(dian)動機(ji)等設備。

4、盡管(guan)傳統定速抽蓄機(ji)組(zu)(zu)完整的工況協聯(lian)控(kong)制技術已比較(jiao)成熟，但由于可變速機(ji)組(zu)(zu)與(yu)傳統機(ji)組(zu)(zu)在結構(gou)、勵磁方式(shi)和控(kong)制方法上差異均較(jiao)大(da)，導致傳統機(ji)組(zu)(zu)的監控(kong)系(xi)統工況協聯(lian)控(kong)制方法無法適應可變速機(ji)組(zu)(zu)。

技術總結
本發明提出一種有限狀態機的大型可變速抽水蓄能機組工況轉換方法，涉及大型可變速抽水蓄能機組監控系統工況協調控制技術。所述的方法包括：機組默認工況為停機(S00)，若無輸入事件，則機組一直處于停機(S00)；設置機組工作模式和啟動模式；若機組工作模式設為發電模式(e00)，且接收到機組監控系統的啟動指令(e10)，則機組按照所設定的啟動模式進入發電過程；若機組工作模式設為抽水模式(e01)，且接收到機組監控系統的啟動指令(e10)，則機組按照所設定的啟動模式進入抽水過程。本發明使可變速機組安全、快速而又柔和地實現工況轉換，并且各轉換階段間銜接平滑，為大型可變速抽水蓄能機組監控系統工況協調控制仿真奠定理論基礎。
