| 摘 要： | 电压陷落(电压骤降)是电能质量的重要问题,也是电力工程领域的一个重要研究方向。电压陷落不仅会引起电力系统的安全和电能质量问题,也会危及用电设备的可靠运行。为了解决这个问题,该文提出了一种新型动态电压补偿器的设计,它并无注入变压器,直接串联在低压线路中、保护用电设备。该设计主要解决90%以上的电压陷落,它充分利用电压陷落时电网所剩的电压,达到用最少量的直流电容量来储能的目的。

| Abstract: | Voltage sag is one of main power quality problems;it is also an important research direction of power electrical engineering field.It will cause power quality and power system security problem,and it will also affect reliable operation of electrical equipment.A transformer-less dynamic voltage compensator(DVC) proposed in this study is to address those issues-by injecting compensating voltage directly into power system to mainly mitigate more than 90% events of voltage sag at the customer side.Thus,the load will be protected by the output voltage of DVC and the amount of DC capacitor used for energy storage is minimized and the designed device is cost-effective. |
