This paper describes an algorithm for accurate ﬁlter phase compensation in PMUs.It is based on two realistic assumptions: (1) the group delay of the ﬁltering stages in the system is approximately constant in the frequency range of interest and (2) the information input signal is narrowband. Numerical results conﬁrm the accuracy improvement of this algorithm with respect to a standard compensation and compliance with the IEEE Std. for synchrophasor measurements.
