摘要
电力系统中区域性供电不平衡和负荷波动会导致系统电压跌落,随着用户对电能质量要求的不断提高,解决这类问题显得极为迫切。动态电压恢复器作为治理电压跌落的最有效的途径之一,近些年来受到学者们的广泛关注。控制策略是动态电压恢复器研究中最为关键的部分,主要负责检测、计算和确定补偿所需的电压或电流。不同的控制策略对动态电压恢复器的控制性能不同。对动态电压恢复器中的线性控制策略和非线性控制策略及其改进的控制策略进行综述,阐述了不同控制策略的原理、特点及动态电压恢复器在不同控制策略下控制性能的效果分析。为了进一步推动动态电压恢复器控制策略的研究和发展,对动态电压恢复器控制策略未来需要深入研究的方向进行了展望。
Regional unbalanced power supply and load fluctuations in the power system will cause the system voltage to drop.With the continuous improvement of users'requirements for power quality,it is extremely urgent to solve these problems.As one of the most effective ways to manage voltage sag,dynamic voltage restorer has received extensive attention from scholars in recent years.The control strategy is the most critical part of the research on dynamic voltage restorer.It is mainly responsible for detecting,calculating and determining the voltage or current required for compensation.Different control strategies have different control performances for the dynamic voltage restorer.This paper summarizes the linear control strategy,nonlinear control strategy and its improved control strategy in the dynamic voltage restorer,expounds the principles and characteristics of different control strategies and the effect analysis to the dynamic voltage restorer’s control performance under different control strategies.In order to further promote the research and development of the dynamic voltage restorer control strategy,this paper looks forward to the future research directions on dynamic voltage restorer control strategy.
