采用性能優(yōu)良的電源，抑制電網(wǎng)引入的干擾

? ? 在PLC控制系統(tǒng)中，電源占有極重要的地位。電網(wǎng)干擾串入PLC控制系統(tǒng)主要通過PLC系統(tǒng)的供電電源（如CPU電源、I/O電源等）、變送器供電電源和與PLC系統(tǒng)具有直接電氣連接的儀表供電電源等耦合進入的?，F(xiàn)在，對于PLC系統(tǒng)供電的電源，一般都采用隔離性能較好電源，而對于變送器供電的電源和PLC系統(tǒng)有直接電氣連接的儀表的供電電源，并沒受到足夠的重視，雖然采取了一定的隔離措施，但普遍還不夠，主要是使用的隔離變壓器分布參數(shù)大，抑制干擾能力差，經(jīng)電源耦合而串入共模干擾、差模干擾。所以，對于變送器和共用信號儀表供電應選擇分布電容小、抑制帶大（如采用多次隔離和屏蔽及漏感技術(shù)）的配電器，以減少PLC系統(tǒng)的干擾。

? ? 此外，位保證電網(wǎng)饋點不中斷，可采用在線式不間斷供電電源（UPS）供電，提高供電的安全可靠性。并且UPS還具有較強的干擾隔離性能，是一種PLC控制系統(tǒng)的理想電源。

電纜選擇的敖設

? ? 為了減少動力電纜輻射電磁干擾，尤其是變頻裝置饋電電纜。筆者在某工程中，采用了銅帶鎧裝屏蔽電力電纜，從而降低了動力線生產(chǎn)的電磁干擾，該工程投產(chǎn)后取得了滿意的效果。

? ? 不同類型的信號分別由不同電纜傳輸，信號電纜應按傳輸信號種類分層敖設，嚴禁用同一電纜的不同導線同時傳送動力電源和信號，避免信號線與動力電纜靠近平行敖設，以減少電磁干擾。

? ? 3、硬件濾波及軟件抗干擾措施

? ? 信號在接入計算機前，在信號線與地間并接電容，以減少共模干擾；在信號兩極間加裝濾波器可減少差模干擾。

? ? 由于電磁干擾的復雜性，要根本消除迎接干擾影響是不可能的，因此在PLC控制系統(tǒng)的軟件設計和組態(tài)時，還應在軟件方面進行抗干擾處理，進一步提高系統(tǒng)的可靠性。常用的一些措施：數(shù)字濾波和工頻整形采樣，可有效消除周期性干擾；定時校正參考點電位，并采用動態(tài)零點，可有效防止電位漂移；采用信息冗余技術(shù)，設計相應的軟件標志位；采用間接跳轉(zhuǎn)，設置軟件陷阱等提高軟件結(jié)構(gòu)可靠性。
