1) three-phase unbalanced voltage
三相不平衡电压
3) unbalanced three-phase voltage
不平衡三相电压，不对称三相电压
4) unbalanced voltage sags
三相不平衡电压暂降
1.
A method for unbalanced voltage sags detection is presented,which can identify unbalanced voltage sags characteristics,such as magnitude,duration and phase-angle jump.
目前动态电压恢复器(Dynamic Voltage Restorer,DVR)装置中常用的dq变换检测法只适用于三相对称扰动,故提出了一种可用于三相不平衡电压暂降的检测方法。
5) three-phase voltage unbalance factor
三相电压不平衡度
1.
At first,electrical energy quality is calculated and analyzed theoretically from two aspects of harmonic and negative-sequence,including harmonic current injected to point of common coupling(PCC),total harmonic distortion of voltage(THDU) of PCC,three-phase voltage unbalance factor of PCC and voltage fluctuation of PCC,etc.
先从理论上分析比较两种供电电压等级下电气化铁路注入系统的谐波和负序引起的电能质量,其中主要计算比较注入公共连接点母线谐波电流、电压总畸变率、三相电压不平衡度和电压波动等几个重要的电能质量指标。
6) three phase unbalance current
三相不平衡电流
1.
In order to make solutions for system stable influence of the three phase unbalance current by the increasing of unbalance load, the unbalance load integrated theory is described and the balance compensation algorithm based on STATCOM and SVC has been adopted.
随着不对称大负荷增加,三相不平衡电流对系统的稳定性影响也日益严重。
补充资料：三相
【三相】
（名数）一、解脱相，言无生死之相也。二、离相，言无涅槃之相也。三、灭相，言生死涅槃之无相，其无相亦无。即非有非无之中道也。法华经药草喻品曰：“如来说法，一相一味，所谓解脱相离相灭相。”文句七上曰：“解脱相者，无生死相，离相者，无涅槃相，灭相者无相，亦无相。”又曰：三有为相。(参见：有)
