摘　　要：介绍了闪变的概念和闪变测量的基本原理,并根据该原理设计了一种基于虚拟仪器的电压闪变测量模块,对所设计的闪变测量模块进行了仿真验证,用该闪变测量模块对模拟电弧炉装置的电压闪变进行了实际测量,仿真验证和测量结果表明,该闪变测量模块工作稳定,测量精度满足IEC要求,具有一定的工程实用性。The paper discusses the conception of flicker and the basic theory of flicker measurement, and designs a voltage flickermeter based on virtual instrument according to this theory. Then simulation validation is carried out to the designed flickermeter, and practical measurement is taken to the voltage flicker of simulated electric arc-furnace with this flickermeter. Finally, the result of simulation validation and measurement shows that this flickermeter has a certain project practicality with stable running and the accuracy of measurement meeting the requirement of the IEC.
