基波功率的英文
例句與用法
- It is deduced theoretically that non - linear load , rather than linear load , generates harmonics , which translates part of fundamental reactive power absorbed from power system into harmonic reactive power injected into the power system . the rationality of electric power measurement for linear and non - linear load is studied , and as a result some rational advices are addressed here
從理論上推導(dǎo)了線性負載不產(chǎn)生諧波，非線性負載將吸收的部分基波功率轉(zhuǎn)化為諧波功率注入系統(tǒng)，并對電能計量準確性和合理性做了一些探討，最后提了一些無功的收費意見。 - What the subject researching is that power energy should be measured with base wave ammeter to power systematic nonlinear user ; and that it is high veracious by base wave ac parameters measurement method to those not bad contaminative . it is well known that all kinds of ac parameters including of base wave and harmonics , but the content of harmonics in power systems increase largely with the mass disturbance to power using high - power electric equipment . which makes wave shape of voltage and current aberrence , so the measurement veracity and reliability decreased largely . at the same time brings out serious infuency to safe run of power system and electric equipment . the power which any non - linear loads consumes can be divided into two sides , one is base power absorbed in power and the other is minus harmonics power
本課題所研究的問題是針對電力系統(tǒng)非線性負載用戶采用基波電度表來計量電能；而對諧波污染不嚴重的線性用戶采用基波交流參數(shù)測量的方法仍然具有較高的準確性。眾所周知，各種交流參量都包含基波和各次諧波，然而隨著電力電子技術(shù)的迅速發(fā)展，大功率的用電設(shè)備對電網(wǎng)的干擾也是越來越嚴重，導(dǎo)致電力系統(tǒng)諧波含量迅速增長，使電壓和電流的波形產(chǎn)生嚴重畸變，測量的準確性和可靠性都大大降低，同時也對電力系統(tǒng)和用電設(shè)備的安全運行帶來嚴重的影響。任何一種非線性負載所消耗的功率都可以分為兩部分，一部分為從電網(wǎng)中吸取的基波功率，另一部分則是負的諧波功率。
