in this paper a new algorithm based on phasor measurements for estimating the thévenin equivalent (te) and system inertia constant is proposed. the method estimates the network te seen from a generator terminal and equivalent system inertia constant by means of phasor data that is available at phasor data concentrator (pdc) center. it is shown that the parameters of the te could be estimated at...

We wanted to use a multiple probes and white light interferometer to measure the surface profile of thin film. However, this system, as assessed with a scanning method, suffers from the presence of a moving stage and systematic sensor errors. In this paper, in order to separate measurement error caused by the moving stage and systematic sensor errors, the least squares analysis is applied to ac...
