摘要:自電能產(chǎn)生以來,它在一定程度上加速了社會發(fā)展。作為商品,電能的質(zhì)量是衡量其價(jià)值的關(guān)鍵,且不同用戶對電能質(zhì)量的需求各異。因此,開展相關(guān)研究,提出切實(shí)可行、經(jīng)濟(jì)合理且易于實(shí)施的效能優(yōu)化方案,可為企業(yè)電能質(zhì)量管理提供科學(xué)決策依據(jù)。

Abstract: Since the advent of electric energy, it has accelerated social development to some extent. As a commodity, the quality of electric energy is the key to measuring its value, and different users have different requirements for the quality of electric energy. Therefore, it is necessary to conduct relevant research and propose practical, economically reasonable, and easy-to-implement efficiency optimization schemes to provide scientific decision-making basis for enterprise power quality management.
Keywords: high-order power quality; online monitoring device; analysis software; system application

隨著變電站及配電系統(tǒng)線路不斷增多,電網(wǎng)系統(tǒng)供配電設(shè)備在不斷的更新,設(shè)備功率在不斷增加,用電設(shè)備的容量也越來越大;三相負(fù)荷不平衡、電力系統(tǒng)諧振接地等會產(chǎn)生負(fù)序,大功率整流和非線性設(shè)備等會產(chǎn)生諧波,長期運(yùn)行會導(dǎo)致電能質(zhì)量下降,嚴(yán)重威脅供電、用電設(shè)備的安全運(yùn)行。(剩余3775字)
