PMU’s Behavior with Flicker-Generating Voltage Fluctuations: An Experimental Analysis

An Experimental Analysis of Intertemporal Allocation Behavior

If the future is uncertain, optimal intertemporal decisions rely on anticipating one’s own optimal future behavior as is typical in dynamic programming. Our aim is to detect experimentally stylized facts about intertemporal decision making in a rich stochastic environment. Compared to previous experimental studies our experimental design is more complex since the time horizon is uncertain and t...

Voltage Flicker Reduction with Svc in Steel Plant

The voltage flicker is main factor influencing the power quality and SVC is well-proven solution. The flicker reduction requires very short response time, according to the relation analysis between flicker improvement factor and response time. SVC has a fast open-loop control function to achieve effective voltage support. The fast algorithm of flicker reduction is presented here based on synchr...

Voltage Flicker Detecting Based on Improved HHT

Abstract: This paper puts forward a new method based on Hilbert-Huang Transform (HHT) and Wavelet denoising for extracting feature information of voltage flicker signal. Firstly, envelope signal could be extracted by using HHT from original signal containing noises. Then the noises and higher harmonic components of envelope signal could be removed by using Wavelet denoising. Finally, the noise-...

Characterizing dynamic behavior of PMUs using step signals

Evaluating performance of PMUs to verify the consistency of phasor measurements is of a great importance since it promotes the interoperability among PMUs from different manufacturers. This paper presents a set of test methodology and tools for evaluating the dynamic performance of PMUs when exposed to a step change of input signals. A phasor estimation scheme is proposed to achieve high accura...
