Detection of systematic errors in PMU measurements by the power system state estimation methods

... determines the current state of a power system. For this purpose synchronized phasor measurements from PMU are used in combination with SCADA measurements. A method of test equations (TE) is used to detect gross errors in both SCADA and PMU measurements. The mathematical expectation of the TE discrepancy is used to identify a systematic error in measurements. The non-zero value of this expectation can only testify to the presence of a systematic error in measurements contained in TE, but cannot be used to ...
