voltage regulation factor

A power quality problem can be defined: problem due to frequency, voltage regulation, voltage dips, flicker, transients, harmonics, and power factor and 3 phase imbalance.

电能质量问题被定义为：频率、电压所导致的问题，如电压跌落、电压闪变、电压短时中断、谐波、功率因数以及三相不平衡度。

Single meter threshold logic detection checks if the phase voltage, phase current or power factor acquired from one electric meter violates the limits, or if the energy consumption increment follows its own regulation.

单表阀值逻辑检测是检测单个电度表上的相电压、相电流、功率因数是否越限或判断电量增值是否符合自身的规律确定是否有窃电发生；

At last, the resonance rectifier method is brought into improve the power factor of back stage AC voltage regulation module.

最后探讨了一种谐振整流电路，以提高后级交流电压调节模块的功率因数。
