摘要
随着可再生能源发电在中低压配电网中接入比例不断升高,加上电力电子化冲击性、非线性负荷的大量应用,现代配电网中的电能质量问题受到广泛关注。选取电压质量、三相不平衡和谐波谐振三个电能质量典型问题进行概述,并结合国内外研究现状,针对每种典型电能质量问题梳理出若干条相对应的治理方案,最后总结出引发新能源配电网电能质量问题的原因虽然是电力电子技术的大规模应用,但电力电子化治理方案也是未来新能源配电网电能质量问题治理中必不可少的角色。
With the increasing proportion of renewable energy power generation accessed in medium and low-voltage distribution networks,as well as the massive application of power electronic impact and nonlinear loads,the power quality problems in modern distribution networks have received widespread attentions.In this paper,three typical power quality problems,namely,voltage quality problem,three-phase unbalance problem and harmonic resonance problem,are selected to be outlined.Combined with the research status at home and abroad,several corresponding solutions are sorted out for each problem.Finally,it is concluded that the power quality problems in new energy distribution networks arise from the large-scale application of power electronics technology.However,power electronic solutions will play an important role in dealing with the power quality problems in the future distribution networks.
