This paper presents various applications of a nonlinear adaptive notch filter which operates based on the concept of an enhanced phase-locked loop (PLL). Applications of the filter for online signal analysis for power systems protection, control a

The CS5460A is a highly integrated power measurement solution which combines two   Analog-to-digital Converters (ADCs), high-speed power calculation functions, and a serial interface on a single chip. It is designed to accurate

This paper presents harmonic and reactive power compensation based on a generalized theory of instantaneous reactive power for three-phase power systems. This new theory gives a generalized definition of instantaneous reactive power,which is valid

This paper, focus on the study and design of a shunt active power (APF) filter for the compensation of harmonic currents and reactive power in polluted environment and under unbalanced network voltage. In APF design and control, p-q theory was often
