This paper discusses the application of the hierarchical state estimation technique to wide-area monitoring. A wide-area network comprised of a large number of interconnections between various utilities requires monitoring of the entire system. Hierarchical state estimation can be modified to consolidate the state outputs from the existing state estimators(More)
Wavelet Transform is a mathematical tool for time frequency analysis of non stationary signals like the current waveform in electric traction system. The locomotives used in traction system have different types of traction motors –dc and three phase ac motors with different methods of speed control. Hence technologies will be different depending on the type(More)
