Abstract:
One of the enabling technologies for smart grid development are synchrophasor measurements typically performed by devices called phasor measurement unit (PMU), that produce synchronized subsecond high-resolution voltage and current measurements, so greatly augment the traditional response time of supervisory control and data acquisition measurements. In this paper we present an algorithm that measures amplitude, frequency and phase of voltage and current phasors with great accuracy. It is based on the recursive search of the solution of the maximum likelihood function and can track small variations of all phasor parameters. Preliminary results show that its performance is comparable to the Cramer-Rao Lower Bound.
