Originally, ancillary services (ASs) were provided by large-scale power plants to ensure the
secure and reliable operation of power systems. However, with the advent of renewable …

The aim of this paper is the broken rotor bars fault detection for a sensorless vector
controlled induction motor drive. The technique of control used is based on the field-oriented …

State estimation is an important area required for enabling proper operation and control of
the power system and its real-time monitoring. Correct knowledge of the states (like rotor …

Wireless sensor networks equipped with rechargeable batteries are useful for outdoor
environmental monitoring. However, the severe energy constraints of the sensor nodes …

This article deals with the parameters' measurement of interarea oscillations, which are low-
frequency damped oscillations that affect the high-voltage transmission lines when an …

This paper proposes a new algorithm for estimating the resonant frequency of adaptive
notch filters used in servo systems. Notch filters and adaptive notch filters are widely used in …

This paper develops a robust estimator of correlation as a data preprocessing stage to the
Prony method that is able to suppress white impulsive noise. The method consists of the …

The inclusion of the governor droop and dead-band in dynamic models helps to reproduce
the measured frequency response accurately and is a key aspect of model validation. Often …

Abstract Nowadays, GNSS (Global Navigation Satellite System) receivers can measure with
sampling rates up to 100 Hz, and it is possible to provide displacements at a level of …

Recently, the application of the adaptive notch filter (ANF) concept to the analysis of damped
oscillations and the estimation of frequency and dam** factor of such oscillations was …
