negative sequence

基本解釋

For the power quality control and relay protection, it is very important of rapid, correct and practical detection of the negative sequence fundamental current.
快速、準(zhǔn)確、實(shí)用的負(fù)序基波電流檢測(cè)方法對(duì)於電能質(zhì)量監(jiān)測(cè)與控制、繼電保護(hù)等具有極其重要的意義。
This control principle can improve the control of power quality and effectively compensate the harmonic currents at load side, reactive power and negative sequence current.
該控制方法能改善系統(tǒng)電能質(zhì)量的調(diào)節(jié)，有傚地補(bǔ)償負(fù)荷側(cè)諧波電流、無(wú)功功率和負(fù)序電流。
With the substantial growth of power electronic devices and unbalanced loads in power systems, the outcoming harmonics and negative sequence endanger the running safety of the generators seriously.
隨著電力系統(tǒng)中電力電子裝置以及不平衡負(fù)載大量增加，諧波和負(fù)序汙染日趨嚴(yán)重，它們對(duì)發(fā)電機(jī)的運(yùn)行安全帶來(lái)危害。

負(fù)序
The basic concept of the single phase tractive power negative sequence to the electrified railroad was introduced in this paper. It analyses the negative influence of negative sequence influence to generator,electric motor,power transformer and transmission line.
介紹了電氣化鉄路單相牽引供電負(fù)序的基本概唸,詳細(xì)分析了負(fù)序?qū)Πl(fā)電機(jī)、電動(dòng)機(jī)、電力變壓器、輸電線路和繼電保護(hù)的負(fù)麪影響,論述了對(duì)電氣化鉄路中單相牽引供電負(fù)荷負(fù)序影響採(cǎi)取對(duì)策的必要性,提出了改變這種不良影響的對(duì)策。
