The measurement of power factor and reactive power is indispensable in reactive power compensation.In this paper
several mainstream measurement methods in the reactive power compensation controller
such as phase-time conversion
S.Fryze generalized reactive power
AC sampling phase shift
DFT fundamental wave
pq algorithm based on instantaneous reactive power theory
are analyzed in detail.The characteristics of those measurement methods
automatic phase identification condition and applicable condition from the standard point of compensation are discussed.It is shown by the analysis that the controller adopting DFT fundamental wave and pq algorithm is suitable to various working conditions including large harmonic current.If power grid voltage distortion smaller
the AC sampling phase shift method also has the same effect.
