PLC是一種可以進行編輯邏輯的控制器。PLC技術是自動化技術中十分關鍵的部分之一。這一技術在實際應用中有著較高的便捷性。PLC技術在電力系統(tǒng)當中通常是在數(shù)字控制系統(tǒng)的邏輯控制方面進行應用，也是系統(tǒng)反饋的重要環(huán)節(jié)。因此，PLC技術在我國的配電系統(tǒng)自動化當中有著重要的推動效果。此外，PLC技術在電力系統(tǒng)的故障檢修和養(yǎng)護方面也有著很好的作用，可以有效地降低電力系統(tǒng)的故障檢修成本。在電力系統(tǒng)當中PLC技術主要在以下幾個方面進行應用：1）PLC技術在閉環(huán)操作中的應用。在電力系統(tǒng)的閉環(huán)操作中，需要對環(huán)境溫度等因素進行模擬計算，在確定數(shù)值后對環(huán)境因素進行有效的控制。模擬計算的過程中需要使用PLC技術當中的I/O狀態(tài)對環(huán)境因素進行閉環(huán)控制。其中D/A和A/D之間的轉換操作十分重要，需要應用PID系統(tǒng)技術進行對應的操作。要程度上保證系統(tǒng)的轉換效率。通過對信息數(shù)據(jù)系統(tǒng)轉換效率的提高，整個電力系統(tǒng)的運行效果也會隨之增長[5]。2）PLC技術的順序控制應用。當前，我國的科學技術水平有著十分明顯的提高，因此很多電力企業(yè)在系統(tǒng)方面也進行了相應的更新，一些傳統(tǒng)的控制系統(tǒng)也開始應用PLC技術的控制系統(tǒng)。這種系統(tǒng)在實際應用過程中能夠大程度地提高電力系統(tǒng)的生產效率，降低系統(tǒng)對資源的損耗，為電力企業(yè)帶來良好的經(jīng)濟效益。PLC技術在控制系統(tǒng)的改善過程中，可以利用信息模塊提高系統(tǒng)效率。通過PLC技術可以對電力生產工作進行有效的管理和調控，并對系統(tǒng)的操作順序有的改善[
