Abstract

Power quality problem is a very big problem in power system, some equipment is installed in the power system to solve it, among them dynamic voltage restaurateur is one of the best equipment. Many types of control techniques can be installed in dynamic voltage restaurateurs. Three types of control methods have been adopted in this research work. Various types of the control techniques such as PI control technique, PR control technique, and hysteresis control technology has been investigated. In this study, two major effects of power quality have been taken, which include voltage sag and voltage swell. These two power quality problems are included up to 30 percent, which is solved through all three methods. Based on the analysis of control technology, the “PI control” method is the best method for Dynamic Voltage Restorer. In this study, Designed control strategies using PI PR Hysteresis controller, with comparative analysis for the implemented for the DVR. PI PR control strategies are designed for medium-level voltage and Hysteresis control strategy design for low-level voltage.

动态电压恢复器控制策略的比较分析

电能质量问题是电力系统中一个非常大的问题，电力系统中安装了一些设备来解决电能质量问题，其中动态电压餐厅就是最好的设备之一。许多类型的控制技术可以安装在动态电压餐馆。本研究工作采用了三种控制方法。研究了各种类型的控制技术，如PI控制技术、PR控制技术和迟滞控制技术。本文主要考虑了电压凹陷和电压膨胀对电能质量的影响。这两个电能质量问题包括高达30%，这是通过所有三种方法解决。通过对控制技术的分析，认为“PI控制”方法是动态电压恢复器的最佳控制方法。在本研究中，设计了PI - PR迟滞控制器的控制策略，并对其在DVR中的实现进行了对比分析。针对中电压设计了PI - PR控制策略，针对低电压设计了迟滞控制策略。
