New adaptive algorithm for precise voltage phasor measurement in a series compensated network

Abstract

This paper describes a new adaptive algorithm which estimates the positive sequence voltage phasor in a series compensated network with a high precision. This measurement is used in a shunt reactor switching scheme which will control voltage profiles along the Hydro-Quebec transmission grid. The particular nature of the noise observed in the voltage wave forms is discussed. The noise particularities have been considered in the development of the algorithm. The real time implementation of the algorithm is briefly discussed.
