line-voltage variation 中文意思是什麼
line-voltage variation
解釋
線路電壓變化-
The background harmonic voltage is related with not only the power of harmonic sources and variation of power line voltages but also the power system structure and capability
背景諧波電壓不僅與電網中諧波源強弱、網壓變化有關，而且與電網容量、結構有關。 -
The non uniform variation along the line of the input impedance calculated from phasor voltage to current ratio is conformed with that calculated from the phasor ratio of one plus the reflection and one minus reflection along the line
數值驗證，由駐波電壓與駐波電流之相量比及由沿傳輸線一加反射與一減反射相量比計算所得之輸入阻抗，沿傳輸線之不均勻變化是一致的。 -
For an ev drive system, the variation of rotor time constant will bring on variation of torque and exorbitant line voltage even the field orientation may be destroyed. the varied torque will affect ev dynamic performance, and the higher voltage will limit the output power due to the bound of batteries in ev
對于電動汽車驅動系統來說，轉子時間常數的波動會導致輸出轉矩和電機電壓的波動，並且嚴重時會導致系統出現振蕩，轉矩的波動會影響汽車的動態性能，電機電壓的波動則會由於電池電壓的限制而影響電機的輸出功率，這些都是電動汽車的驅動系統應該避免的問題。 -
This article has discussed the control problem in a distribution substation and on the distribution line respectively. reactive power / voltage control in a substation using general approach usually results in the voltage of the second side being too close to the boundary. it will make the ability of enduring the variation of load in a system decrease a lot and become the threat of the system
本文分別對配電系統中的變電站及配電線路的無功電壓優化控制問題進行了研究，採用常規方法進行變電站電壓無功控制時，往往使二次側電壓過于接近邊界而導致系統承受負荷波動的能力大大下降，成為系統安全運行的隱患。
