描述

電能質(zhì)量是指公用電網(wǎng)對(duì)電力用戶公共連接點(diǎn)的電壓質(zhì)量和電力用戶在公共連接點(diǎn)對(duì)公用電網(wǎng)的干擾水平?？捎弥C波電壓、電壓偏差、電壓波動(dòng)和閃變、三相電壓不平衡度、電壓暫降、電壓暫升、諧波電流、負(fù)序電流等參數(shù)描述。

節(jié)能降耗就是應(yīng)用技術(shù)上可靠、經(jīng)濟(jì)上可行合理、環(huán)境和社會(huì)都可以接受的方法，有效利用能源，提高用能設(shè)備或工藝的能量利用效率，降低能源的損失與浪費(fèi)。

隨著電網(wǎng)電能質(zhì)量污染的日益嚴(yán)重，各種電能質(zhì)量治理措施提上日程，它們對(duì)系統(tǒng)的節(jié)能降耗起到了積極的作用。而近年來(lái)電力電子技術(shù)的進(jìn)步也帶動(dòng)節(jié)能技術(shù)、設(shè)備不斷發(fā)展，在電網(wǎng)中大量應(yīng)用的節(jié)能設(shè)備都使用了現(xiàn)代電力電子技術(shù)，將不可避免地對(duì)電網(wǎng)電能質(zhì)量產(chǎn)生一定的影響。因此，有必要對(duì)電能質(zhì)量和節(jié)能之間的關(guān)系進(jìn)行研究，以便更好地解決各相關(guān)問(wèn)題。電能質(zhì)量治理與節(jié)能降耗的關(guān)系可以從兩個(gè)方面來(lái)論述：一是治理電網(wǎng)電能質(zhì)量會(huì)帶來(lái)節(jié)能效益，二是節(jié)能、設(shè)備技術(shù)對(duì)電網(wǎng)電能質(zhì)量也有影響。
