Phasor measurements impact on the a priori data filtration and power systems state estimation

An effective method of remote metering data validation is the a priori filtration applied in conjunction with the conventional state estimation procedure. The a priori filtration aimed to the gross remote measurement error detection is applied before the state estimation procedure. The phasor measurements unit implementation significantly improves the efficiency of a priori filtration and further state estimation. Even the partial equipment of power system with the phasor measurement units allows the power systems state information quality improvement.
