在供配電系統(tǒng)中，穩(wěn)定的運行是整個供配電系統(tǒng)的基本要求，要保障在供電、輸電、配電等每個環(huán)節(jié)的及穩(wěn)定。供配電的功能就是供應(yīng)各個區(qū)域的所需電力量，達(dá)到合理分配，并且在此過程中盡量減少電力損耗，并且能夠運行。把電氣自動化控制技術(shù)運用到整個系統(tǒng)中，不僅可以提高供配電的運行效率，而且可以確保整個電路運行穩(wěn)定，降低隱患的發(fā)生概率，保障整個系統(tǒng)的性能。在供配電系統(tǒng)中，運用到電氣自動化控制技術(shù)，對于整個電力行業(yè)而言，是科學(xué)技術(shù)領(lǐng)域的創(chuàng)新，它推動了行業(yè)發(fā)展，帶來了巨大的經(jīng)濟(jì)效益，對行業(yè)和社會的發(fā)展都具有重要意義。把互聯(lián)網(wǎng)技術(shù)、PLA技術(shù)、電氣自動化控制技術(shù)三者結(jié)合起來并應(yīng)用于供配電系統(tǒng)中，可以實現(xiàn)系統(tǒng)的自行控制和管理模式。加強管理人員的意識，提高對危險的防范意識，并把這些意識融入應(yīng)用中去，通過智能化、自動化的電力供應(yīng)，降低人員操作引發(fā)的失誤，使整個系統(tǒng)的運行效果得到提升。
