- Voltage sag is one of the most serious power quality problems which impacts many electric equipments. Rapidly and accurately detecting the characteristics of the voltage sag is crucially important for voltage sag compensation. Used in the detection of voltage sag, traditional transform method which has good real-time performance and high accuracy brings time delay, so it cannot satisfy the requirement of compensation. In this paper, an improved transform method of voltage sag is proposed, which can achieve the purpose of testing considering the effects of harmonic without the filter. The improved transform method for voltage sag detection not only has good real-time performance but also has high accuracy. The simulation results verify the validity of the method.
