水下電弧有著廣泛的用途,其中應用之一是水下制取“電弧氣”。制造電弧氣的一個關鍵要素就是保持電弧電壓的穩(wěn)定,使電弧能在水下穩(wěn)定放電。大電流(1000 A,DC)、大功率(50 kW)水下電弧放電本身是一個復雜的過程,電弧長度短,具有非線性、變參數、不易穩(wěn)定等特點。試驗表明采用PFC-PID串級控制策略的水下電弧控制系統(tǒng)的動態(tài)品質明顯優(yōu)于采用傳統(tǒng)PID控制的系統(tǒng),具有較強的魯棒性和抗干擾能力。 大多數PID控制都是基于單片機進行,但單片機控制的DDC系統(tǒng)軟硬件設計較為復雜,特別是涉及到邏輯控制方面更不是其長處,而PLC在這方面卻是公認的選擇。隨著PLC功能的擴充,許多PLC控制器中都集成了PID控制功能,因此在邏輯控制與PID控制混合的應用場所中采用PLC控制是較為合理的。經過認真的市場調研和技術準備,筆者使用了目前比較先進的PLC技術開發(fā)控制系統(tǒng),對現(xiàn)場各種生產過程信號進行采集.監(jiān)測、計量。從實際應用的效果來看,該系統(tǒng)具有性價比高、可維護性強、性能穩(wěn)定等優(yōu)點。
系統(tǒng)的工作原理 在水下電弧控制系統(tǒng)中,電弧放電在反應器中完成,氣體由此產生。電極控制裝置連續(xù)地將碳棒電極送入反應器中并維持電極電弧的穩(wěn)定,從而保持電弧電壓和電流的恒定,使得產氣成分穩(wěn)定且產氣效率提高。水下電弧控制系統(tǒng)示意圖如圖所示。
