电力系统闪变的高精度检测是闪变评估和治理的前提和基础.从闪变产生的机理出发,对波动负荷和间谐波引起的电压闪变特性和测量方法进行分类总结.结合现有IEC闪变仪对于荧光灯闪变和频率高于100Hz间谐波导致的闪变无法检测的两点不足,对电力系统闪变检测中需要关注的问题和研究方向进行了探讨.总结了2010年版IEC 61000-4-15新标准与原标准的不同,并指出新型闪变仪设计中应注意的问题.

Accurate flicker measurement in electrical power systems is the foundation of flicker assessment and mitigation schemes designing. From the point of the flicker mechanism and characteristic, the paper totally discusses the periodically changed loads and inter-harmonic, as well as its detection methods. It also proposes some research points in the future, considering that the deficiency of the IEC flicker meter for measuring fluorescent lamp flickers and interharmonic-caused flickers with frequency higher than 100Hz. Furthermore, the updates of the IEC 61000-4-15 and some design problems for the new flicker meter are also summarized in the paper.
